SCFHS Saudi Nursing Licensing Exam (SNLE) — Questions and Answers

Question 1: A patient admitted to a NGHA hospital has a history of chronic liver disease and presents with upper GI bleeding. He is started on octreotide infusion. After endoscopy reveals esophageal varices with active bleeding, band ligation is performed. On day 3, the patient develops fever of 38.9°C, abdominal pain, and ascitic fluid analysis shows: WBC 420 cells/mm³ with >70% polymorphonuclear cells, protein 12 g/L, LDH 180 U/L, glucose 5.1 mmol/L. What is the MOST likely diagnosis and the nurse's priority intervention?

Tuberculous peritonitis; initiate respiratory isolation precautions immediately
Secondary bacterial peritonitis; prepare the patient for emergency surgical drainage
Spontaneous bacterial peritonitis (SBP); ensure IV albumin is administered alongside antibiotic therapy as prescribed (Correct answer)
Hepatic encephalopathy precipitated by infection; administer lactulose 30 mL orally stat

Correct answer: Spontaneous bacterial peritonitis (SBP); ensure IV albumin is administered alongside antibiotic therapy as prescribed

The ascitic fluid PMN count ≥250 cells/mm³ with clinical signs confirms spontaneous bacterial peritonitis (SBP), a common and life-threatening complication in cirrhotic patients with ascites. The protein level of 12 g/L is consistent with SBP (not secondary peritonitis, which typically shows higher protein, LDH > serum LDH, and glucose <2.8 mmol/L). The critical nursing priority, alongside ensuring prescribed antibiotic therapy (e.g., cefotaxime), is to ensure IV albumin (1.5 g/kg on day 1) is administered as it significantly reduces renal impairment and mortality — a distinction unique to SBP management per EASL and SCFHS-aligned guidelines. Surgical drainage is for secondary peritonitis. TB peritonitis would require further workup and the fluid profile differs.

Question 2: The nurse is preparing to apply physical restraints to an agitated patient. Which action is most important?

Apply restraints immediately to ensure staff safety
Document restraint use but no physician order is needed
Apply restraints and then contact the physician for an order
Explore all less restrictive alternatives before applying restraints (Correct answer)

Correct answer: Explore all less restrictive alternatives before applying restraints

Restraints are a last resort and must be used only when all less restrictive alternatives have been tried and failed. A physician order is required (retroactively in emergencies). Restraints carry risks including injury, aspiration, and psychological harm.

Question 3: Which electrolyte imbalance is most commonly associated with muscle cramps, tetany, and positive Chvostek's sign?

Hypocalcemia (Correct answer)
Hyponatremia
Hypercalcemia
Hyperkalemia

Correct answer: Hypocalcemia

Hypocalcemia causes neuromuscular excitability, resulting in muscle cramps, tetany, and positive Chvostek's sign (facial muscle twitching when tapping the facial nerve). Hypercalcemia causes muscle weakness and lethargy.

Question 4: A nurse is preparing to administer a blood transfusion to a patient in a Saudi MOH hospital. After confirming the patient's identity using two identifiers, the nurse notes the blood unit was issued 28 minutes ago. The patient's baseline vital signs are: BP 118/76 mmHg, HR 82 bpm, Temp 37.1°C. Fifteen minutes into the transfusion, the patient reports lower back pain and the nurse notes haemoglobinuria. Which action is the highest priority?

Collect a urine specimen and obtain a 12-lead ECG before making any transfusion changes
Slow the transfusion rate to 30 mL/hour and reassess vital signs every 5 minutes
Stop the transfusion immediately, keep the IV line open with normal saline, and notify the physician and blood bank (Correct answer)
Administer IV diphenhydramine as prescribed and continue the transfusion at the current rate

Correct answer: Stop the transfusion immediately, keep the IV line open with normal saline, and notify the physician and blood bank

Lower back pain and haemoglobinuria are hallmark signs of an acute haemolytic transfusion reaction (AHTR), the most dangerous transfusion reaction caused by ABO incompatibility. Per SCFHS nursing standards and Saudi MOH haemovigilance protocols, the nurse must immediately stop the transfusion, maintain IV access with 0.9% NaCl via new tubing, notify the physician and blood bank, and return the blood unit with a fresh patient sample for re-crossmatch. Slowing the rate or administering antihistamines is appropriate for allergic reactions, not haemolytic ones, and delays life-saving intervention.

Question 5: A 24-year-old primigravida at 41+3 weeks gestation undergoes an oxytocin induction of labor in a Saudi tertiary hospital. The electronic fetal monitoring (EFM) shows a baseline FHR of 145 bpm, with repeated late decelerations after every contraction, and minimal variability (amplitude 2–5 bpm) over 40 minutes. The cervix is 5 cm dilated. The attending nurse should FIRST:

Increase IV fluid rate to 500 mL normal saline over 30 minutes and continue monitoring for another 20 minutes
Prepare for immediate operative vaginal delivery as the cervix is sufficiently dilated
Place the mother in a left lateral position, discontinue oxytocin, administer O₂ via face mask at 8–10 L/min, and call the obstetrician immediately (Correct answer)
Perform amnioinfusion to relieve variable decelerations and re-evaluate the FHR pattern

Correct answer: Place the mother in a left lateral position, discontinue oxytocin, administer O₂ via face mask at 8–10 L/min, and call the obstetrician immediately

Repeated late decelerations with minimal variability constitute a Category III (ominous) fetal heart rate pattern per ACOG/SCFHS intrapartum guidelines, indicating uteroplacental insufficiency and possible fetal acidemia. The priority nursing actions are: position change to lateral decubitus (improve uteroplacental blood flow), immediate oxytocin discontinuation (remove uterotonic stimulus), supplemental oxygen, IV fluid bolus, and urgent physician notification for possible emergency cesarean delivery. Amnioinfusion addresses variable decelerations (cord compression), not late decelerations.

Question 6: What is the nursing consideration for administering insulin lispro (Humalog)?

Give immediately before or within 15 minutes of eating due to its rapid onset of action (Correct answer)
It can only be given intravenously
Give at bedtime only
Give 1 hour before meals

Correct answer: Give immediately before or within 15 minutes of eating due to its rapid onset of action

Insulin lispro is a rapid-acting insulin with onset in 15 minutes. It must be given immediately before eating (within 15 minutes) to match the postprandial glucose rise. Giving it too early without food risks hypoglycemia.

Question 7: A nurse in a Saudi NICU is caring for a premature infant at 28 weeks gestation receiving phototherapy for hyperbilirubinemia. The infant suddenly develops abdominal distension, bloody stools, and temperature instability. The attending neonatologist suspects Necrotizing Enterocolitis (NEC). Which nursing action is the HIGHEST priority at this moment?

Obtain a stool culture and administer a glycerin suppository to relieve distension
Increase the phototherapy irradiance level and reposition the infant
Discontinue all enteral feeds immediately and notify the physician for NPO orders and IV access (Correct answer)
Continue current feeds but reduce volume by 50% until culture results return

Correct answer: Discontinue all enteral feeds immediately and notify the physician for NPO orders and IV access

The clinical triad of abdominal distension, bloody stools, and temperature instability in a premature neonate is a hallmark presentation of NEC (Bell Stage II or higher). The immediate life-saving priority is bowel rest — all enteral feeds must be stopped immediately to prevent intestinal perforation, sepsis, and death. Subsequent management includes gastric decompression via nasogastric tube, IV fluids, broad-spectrum antibiotics, and surgical consultation. Continuing or modifying feeds in any amount is contraindicated. Phototherapy management is irrelevant to this emergency. This aligns with Saudi MOH NICU care protocols and SCFHS neonatal nursing standards.

Question 8: The nurse is caring for a post-operative patient with a nasogastric tube. Before administering tube feeding, the nurse should first:

Flush the tube with 30 mL of water
Elevate the head of the bed to 30 degrees
Verify tube placement by checking gastric pH and/or X-ray (Correct answer)
Check the patient's last bowel movement

Correct answer: Verify tube placement by checking gastric pH and/or X-ray

Verifying NG tube placement is the critical first step before any feeding to prevent aspiration. pH testing (gastric pH <5) and chest X-ray are the most reliable methods. Auscultation alone is no longer considered reliable.

Question 9: What are the principles of de-escalation when dealing with an agitated patient?

Maintain safe distance, use calm voice, offer choices, set clear limits, acknowledge feelings, and avoid threatening body language (Correct answer)
Match the patient's aggressive tone
Use physical force immediately
Ignore the patient until they calm down

Correct answer: Maintain safe distance, use calm voice, offer choices, set clear limits, acknowledge feelings, and avoid threatening body language

De-escalation principles: maintain safe distance (arm's length), calm low tone of voice, non-threatening body language, acknowledge the patient's feelings, offer limited choices (empowerment), set clear limits, remove audience, and offer medication or a quieter space.

Question 10: During a routine ward round in a Saudi hospital, a nurse notes that a patient's surgical wound shows the following: wound edges are well-approximated, slight serous drainage is present, and a thin, pale-pink layer of epithelium is visible across the wound surface. No sutures remain. This presentation is best described as which phase and type of wound healing?

Inflammatory phase; healing by tertiary intention
Proliferative phase; healing by primary intention (Correct answer)
Maturation (remodelling) phase; healing by primary intention
Proliferative phase; healing by secondary intention

Correct answer: Proliferative phase; healing by primary intention

The proliferative phase of wound healing (days 3–24) is characterised by the formation of granulation tissue, collagen synthesis, angiogenesis, and epithelialisation — visible here as the thin pink epithelial layer migrating across the wound. Well-approximated wound edges with a clean suture line indicate primary intention healing (wound edges are surgically closed). Secondary intention involves an open wound healing from the base with significant granulation. Tertiary intention (delayed primary closure) involves a wound left open initially then closed later. The maturation phase would show a contracted, pale, avascular scar.

Question 11: During a group therapy session at a SCFHS-accredited psychiatric rehabilitation center in Saudi Arabia, a nurse observes that one patient is monopolizing conversation, speaking rapidly, and interrupting others. A second patient becomes visibly distressed and begins making subtle self-harm gestures under the table. Using therapeutic group dynamics principles, what is the nurse's PRIORITY intervention?

Pause the session and address both issues simultaneously to the entire group to maintain transparency
Immediately and privately remove the distressed patient from the group to assess self-harm risk (Correct answer)
Gently redirect the dominant patient's behavior using group process feedback to restore balance
Document the self-harm gestures and address them after the group session concludes

Correct answer: Immediately and privately remove the distressed patient from the group to assess self-harm risk

While managing group dynamics is important, the immediate physical and psychological safety of the individual patient always takes priority over group process. Subtle self-harm gestures indicate escalating distress and potential imminent risk, which requires immediate private assessment using the appropriate risk stratification tool (e.g., Columbia Suicide Severity Rating Scale, C-SSRS, used in Saudi psychiatric settings). Addressing self-harm publicly in front of the group could cause further harm and violates the patient's dignity and privacy rights under Saudi Mental Health Law. Documenting without acting is a critical patient safety failure. Redirection of the dominant patient is appropriate but secondary to the immediate safety concern.

Question 12: A nurse is performing a physical assessment on a post-operative Saudi patient and notes a capillary refill time of 4 seconds in the fingertips. The patient's SpO₂ is 97% and the room temperature is 18°C. How should the nurse interpret this finding?

Abnormal — the SpO₂ discrepancy confirms poor perfusion despite adequate oxygen saturation
Abnormal — indicative of peripheral vascular compromise requiring immediate physician notification
Normal variant — ambient room temperature below 20°C can prolong capillary refill time in healthy individuals (Correct answer)
Normal variant — post-operative patients routinely exhibit capillary refill times up to 5 seconds

Correct answer: Normal variant — ambient room temperature below 20°C can prolong capillary refill time in healthy individuals

Normal capillary refill time is less than 2 seconds in warm conditions. However, cold ambient temperatures (below 20°C) cause peripheral vasoconstriction that physiologically prolongs capillary refill time beyond 2–3 seconds without indicating true peripheral vascular compromise. With an SpO₂ of 97% and no other signs of circulatory impairment, the prolonged CRT in a cold room (18°C) is a normal environmental variant. The nurse should reassess in a warmer environment before escalating.

Question 13: A nurse is preparing a morphine PCA for a 68-year-old patient with chronic kidney disease (eGFR 18 mL/min/1.73m²) post-abdominal surgery. The physician orders morphine 1 mg demand dose with a 10-minute lockout. What is the PRIMARY pharmacokinetic concern specific to this patient?

Increased plasma protein binding reducing the free fraction of morphine available
Accumulation of morphine-6-glucuronide causing prolonged and exaggerated opioid effects (Correct answer)
Reduced hepatic first-pass metabolism leading to increased oral bioavailability
Accelerated renal clearance of the parent compound causing inadequate analgesia

Correct answer: Accumulation of morphine-6-glucuronide causing prolonged and exaggerated opioid effects

Morphine is hepatically metabolized to morphine-3-glucuronide (M3G, which is inactive but may cause neuroexcitatory effects) and morphine-6-glucuronide (M6G). M6G is a potent active opioid metabolite that is renally excreted. In patients with severe CKD (eGFR <30), M6G accumulates significantly, leading to prolonged sedation, respiratory depression, and exaggerated opioid toxicity — even at standard doses. This is why alternative opioids such as hydromorphone (with monitoring) or fentanyl are often preferred in advanced renal impairment in Saudi clinical practice. Morphine PCA in this patient requires extreme vigilance and likely dose reduction or agent substitution.

Question 14: Which class of diuretics can cause hyperuricemia and is therefore used cautiously in patients with gout?

Loop diuretics (Correct answer)
Osmotic diuretics
Potassium-sparing diuretics
Carbonic anhydrase inhibitors

Correct answer: Loop diuretics

Loop diuretics (e.g., furosemide) compete with uric acid for renal tubular secretion, reducing uric acid excretion and raising serum uric acid.

Question 15: The nurse is developing a care plan for a patient with major depressive disorder. Which nursing diagnosis has the highest priority?

Risk for suicide related to hopelessness (Correct answer)
Impaired social interaction related to withdrawal
Disturbed sleep pattern related to depression
Imbalanced nutrition: less than body requirements

Correct answer: Risk for suicide related to hopelessness

In psychiatric nursing, Maslow's hierarchy guides priority. Risk for suicide is a life-threatening priority that supersedes all other nursing diagnoses. Safety is always the first priority regardless of other identified problems in a patient with depression.

Question 16: A nurse is caring for a patient with active pulmonary tuberculosis in the community. How long after initiating effective antibiotic therapy is the patient generally considered non-infectious?

2–3 weeks (Correct answer)
6 weeks
3 months
24–48 hours

Correct answer: 2–3 weeks

After 2–3 weeks of effective anti-TB therapy, sputum smears usually become negative and the patient is considered non-infectious. Clinical improvement typically occurs within the first 2 weeks. This guideline governs return to school or work decisions.

Question 17: A nurse working in a SCFHS facility is preparing to administer a unit of packed red blood cells (PRBCs) to a 45-year-old female patient. Fifteen minutes into the transfusion, the patient complains of low back pain, the nurse notes dark reddish-brown urine in the catheter bag, and the patient's temperature rises from 37.0°C to 38.8°C. What is the nurse's PRIORITY action?

Switch to the secondary IV line, increase IV fluid rate to force diuresis, and administer antipyretics
Slow the transfusion rate to 50 mL/hr, administer IV diphenhydramine, and continue monitoring
Stop the transfusion immediately, keep the IV line open with normal saline via new tubing, and notify the physician (Correct answer)
Stop the transfusion, send the remaining blood bag to the blood bank, and obtain a urine specimen for culture

Correct answer: Stop the transfusion immediately, keep the IV line open with normal saline via new tubing, and notify the physician

The triad of low back pain, hemoglobinuria (dark reddish-brown urine), and fever during a blood transfusion is pathognomonic for an acute hemolytic transfusion reaction (AHTR) — a life-threatening ABO incompatibility. The nurse must STOP the transfusion IMMEDIATELY and keep the IV access patent with normal saline through NEW tubing (to avoid infusing any remaining incompatible blood from the existing tubing). The physician must be notified urgently. While sending the blood bag and obtaining specimens are correct subsequent steps, the immediate priority is stopping the transfusion and maintaining IV access. Slowing the rate (option A) is used for febrile non-hemolytic reactions and is dangerous in AHTR.

Question 18: Which physiological change of normal aging MOST directly increases an elderly patient's risk for hypothermia in air-conditioned Saudi hospital environments?

Increased sensitivity of peripheral thermoreceptors
Increased basal metabolic rate
Thickening of the skin epidermis
Decreased subcutaneous fat and impaired thermoregulatory mechanisms (Correct answer)

Correct answer: Decreased subcutaneous fat and impaired thermoregulatory mechanisms

Normal aging leads to loss of subcutaneous adipose tissue (which provides insulation) and impaired hypothalamic thermoregulation, reducing the body's ability to generate and retain heat. This makes elderly patients in heavily air-conditioned Saudi hospital rooms particularly vulnerable to hypothermia. Basal metabolic rate decreases (not increases) with age; peripheral thermoreceptor sensitivity diminishes; skin becomes thinner, not thicker.

Question 19: A postpartum Saudi woman on Day 3 after a cesarean section develops a fever of 38.6°C, uterine tenderness, and foul-smelling lochia. Her WBC is 18,000/µL. She is breastfeeding her neonate. The physician prescribes clindamycin and gentamicin IV for endometritis. What is the MOST important nursing consideration specific to this pharmacological regimen in the context of breastfeeding?

Both clindamycin and gentamicin are compatible with breastfeeding; continue breastfeeding and monitor the neonate for loose stools (Correct answer)
Substitute gentamicin with amoxicillin-clavulanate oral therapy as IV antibiotics are contraindicated in breastfeeding mothers
Advise pumping and discarding breast milk for 48 hours after each gentamicin dose to protect the neonate
Advise the mother to temporarily discontinue breastfeeding during the course of gentamicin therapy due to ototoxicity risk to the neonate

Correct answer: Both clindamycin and gentamicin are compatible with breastfeeding; continue breastfeeding and monitor the neonate for loose stools

Both clindamycin and gentamicin are classified as compatible with breastfeeding by international lactation pharmacology references (LactMed, WHO). Gentamicin has very low oral bioavailability, so negligible amounts are absorbed by the breastfeeding neonate even if present in breast milk. Clindamycin may cause loose stools in the infant, which should be monitored. Interrupting breastfeeding is not indicated and contradicts Saudi MOH breastfeeding promotion policies, which emphasize maintaining breastfeeding during most maternal antibiotic treatments.

Question 20: A community health nurse in Riyadh is conducting a windshield survey and notices a high prevalence of obesity-related signage at local clinics. According to the Saudi National Plan for Prevention and Control of Overweight and Obesity, which PRIMARY determinant classification should the nurse document as the leading modifiable risk factor driving Saudi Arabia's obesity epidemic?

Hormonal dysregulation secondary to extreme heat exposure
Genetic predisposition unique to the Arabian Peninsula population
Over-reliance on domestic workers reducing physical household activity
Sedentary lifestyle combined with excessive consumption of high-calorie traditional foods (Correct answer)

Correct answer: Sedentary lifestyle combined with excessive consumption of high-calorie traditional foods

The Saudi National Plan for Prevention and Control of Overweight and Obesity identifies physical inactivity and high-calorie dietary patterns (including traditional Saudi foods high in saturated fats and refined carbohydrates) as the primary modifiable determinants. Saudi Arabia has one of the highest obesity rates in the GCC region, with the Ministry of Health attributing it predominantly to lifestyle factors. While cultural practices involving domestic workers contribute marginally, the dual combination of sedentary behavior and caloric excess is documented as the primary driver.

Question 21: A patient presents with a sudden 'thunderclap' headache, neck stiffness, photophobia, and CT showing blood in the subarachnoid space. Which complication should the nurse monitor for most closely in the following days?

Atrial fibrillation
Pulmonary embolism
Aortic dissection
Cerebral vasospasm (Correct answer)

Correct answer: Cerebral vasospasm

Cerebral vasospasm is the most feared delayed complication of subarachnoid hemorrhage, typically occurring 4–14 days after the initial bleed and leading to ischemic stroke.

Question 22: During a school health screening in the Eastern Province, a nurse identifies a 10-year-old male student with a BMI at the 97th percentile, fasting blood glucose of 6.8 mmol/L, and a waist circumference exceeding age-specific Saudi reference norms. According to the Saudi Guidelines on the Diagnosis and Management of Metabolic Syndrome in Children, how should this cluster of findings be classified?

At-risk for metabolic syndrome requiring lifestyle intervention and 3-month follow-up (Correct answer)
Obese with prediabetes — does not meet metabolic syndrome criteria without dyslipidemia confirmation
Impaired fasting glucose only — metabolic syndrome cannot be diagnosed under age 16 per Saudi guidelines
Confirmed metabolic syndrome requiring immediate pharmacological referral

Correct answer: At-risk for metabolic syndrome requiring lifestyle intervention and 3-month follow-up

Saudi pediatric metabolic syndrome guidelines (adapted from IDF pediatric criteria) allow identification of 'at-risk' status in children aged 6–15 using waist circumference plus two additional risk factors. A fasting glucose of 6.8 mmol/L meets the prediabetes threshold (≥5.6 mmol/L per IDF). However, full metabolic syndrome confirmation in this age group requires lipid panel and blood pressure data. The appropriate clinical response is lifestyle intervention (diet, physical activity) with 3-month follow-up — not immediate pharmacotherapy, which is reserved for persistent cases after lifestyle failure. The claim that metabolic syndrome cannot be diagnosed under 16 is incorrect per Saudi-adapted IDF criteria.

Question 23: A patient is prescribed IV heparin infusion for DVT. The initial order is 80 units/kg bolus followed by 18 units/kg/hr infusion. The patient weighs 75 kg. What is the bolus dose and initial infusion rate?

Bolus: 5,000 units; infusion: 1,000 units/hr
Bolus: 6,000 units; infusion: 18 units/hr
Bolus: 6,000 units; infusion: 1,350 units/hr (Correct answer)
Bolus: 8,000 units; infusion: 1,800 units/hr

Correct answer: Bolus: 6,000 units; infusion: 1,350 units/hr

Bolus: 80 units/kg × 75 kg = 6,000 units. Infusion rate: 18 units/kg/hr × 75 kg = 1,350 units/hr. Both calculations use the same weight-based formula. aPTT monitoring guides subsequent dose adjustments per protocol.

Question 24: A nurse working in a Saudi primary healthcare center is conducting a well-child visit for a 15-month-old child. The mother reports the child has not yet started walking and uses only 2-3 words. According to the Saudi Child Health and Development Surveillance Program (Seha), which response is MOST appropriate?

Administer the Ages and Stages Questionnaire (ASQ) and refer only if the score is below the cutoff
Document the findings and schedule a repeat surveillance visit at 18 months
Reassure the mother that gross motor and language development vary widely up to 18 months
Refer the child immediately to a developmental pediatrician for formal evaluation (Correct answer)

Correct answer: Refer the child immediately to a developmental pediatrician for formal evaluation

At 15 months, a child is expected to walk independently (milestone: 12–15 months) and use at least 3 meaningful words. Failing both gross motor and language milestones simultaneously is a significant developmental red flag. Saudi MOH and the Seha Child Development Program mandate immediate referral when two or more developmental domains are delayed at any surveillance visit, rather than watchful waiting until the next scheduled review.

Question 25: Which isolation precaution is required for a patient with active pulmonary tuberculosis?

Droplet precautions with surgical mask
Standard precautions only
Airborne precautions with negative-pressure isolation room and N95 respirator (Correct answer)
Contact precautions with gown and gloves

Correct answer: Airborne precautions with negative-pressure isolation room and N95 respirator

Pulmonary TB is spread via airborne droplet nuclei (<5 micrometers) that remain suspended in air. Airborne precautions require: negative-pressure (at least 6–12 air changes/hour), N95 or higher respirator for healthcare workers, and door kept closed.

Question 26: What are the therapeutic communication techniques used in mental health nursing?

Giving personal opinions and advice
Telling the patient not to worry
Active listening, open-ended questions, reflection, silence, summarizing, and empathic responses (Correct answer)
Changing the subject when uncomfortable

Correct answer: Active listening, open-ended questions, reflection, silence, summarizing, and empathic responses

Therapeutic communication includes: active listening (full attention), open-ended questions ('Tell me about...'), reflection (repeating key thoughts), therapeutic silence, summarizing, empathy, and validation. These build trust and encourage patient expression in Saudi mental health settings.

Question 27: A 54-year-old female is prescribed warfarin for mechanical heart valve anticoagulation (target INR 2.5–3.5). She reports she has been regularly consuming large amounts of waraq al-khadra (dark leafy greens including spinach and parsley) as part of a Ramadan diet. Her INR today is 1.6. The pharmacokinetic explanation for this finding, and the most appropriate intervention, is:

Oxidative compounds in leafy greens induce CYP2C9 enzyme activity, accelerating warfarin metabolism — switch to a CYP2C9-independent anticoagulant
Warfarin undergoes increased renal clearance with high vegetable consumption — increase the dose by 25% and recheck INR in 72 hours
Dietary vitamin K1 in leafy greens competes with warfarin at VKORC1, increasing clotting factor synthesis — adjust warfarin dose upward and counsel on consistent dietary intake (Correct answer)
Chlorophyll binds warfarin in the GI tract reducing absorption — advise the patient to take warfarin 4 hours before eating vegetables

Correct answer: Dietary vitamin K1 in leafy greens competes with warfarin at VKORC1, increasing clotting factor synthesis — adjust warfarin dose upward and counsel on consistent dietary intake

Warfarin acts by inhibiting Vitamin K epoxide reductase complex 1 (VKORC1), blocking recycling of vitamin K and thereby reducing synthesis of clotting factors II, VII, IX, and X. High dietary vitamin K1 (phylloquinone) intake from leafy greens directly counteracts this mechanism by saturating VKORC1 and increasing active vitamin K availability. The INR of 1.6 is below target for a mechanical valve (high thrombosis risk). The correct action is upward warfarin dose adjustment AND consistent dietary counseling — the patient should maintain consistent (not eliminate) leafy green intake, as fluctuation causes INR instability. CYP2C9 induction and GI binding are incorrect mechanisms.

Question 28: A primipara asks the nurse when to expect the onset of true labor. Which characteristic distinguishes true labor from false (Braxton Hicks) contractions?

Contractions stop when the patient walks
Contractions become regular, stronger, longer, and closer together (Correct answer)
Contractions decrease in intensity with hydration
Contractions are felt only in the abdomen

Correct answer: Contractions become regular, stronger, longer, and closer together

True labor contractions progressively increase in frequency, duration, and intensity, cause cervical change, and are not relieved by rest, hydration, or position change. Braxton Hicks contractions are irregular, do not intensify progressively, and may be relieved by activity change.

Question 29: The nurse is teaching a community group about common water-borne diseases in Saudi Arabia. Which pathogen is most commonly associated with contaminated water supplies?

Vibrio cholerae and enterotoxigenic E. coli (ETEC) (Correct answer)
Mycobacterium tuberculosis
Staphylococcus aureus
Influenza A virus

Correct answer: Vibrio cholerae and enterotoxigenic E. coli (ETEC)

Vibrio cholerae (cholera) and ETEC are the most significant water-borne diarrheal pathogens globally and in regions with water supply challenges. They spread through contaminated drinking water and food washed with contaminated water. TB is airborne; influenza is droplet; Staph is contact/food.

Question 30: Which of the following is a NANDA-approved nursing diagnostic statement format?

Risk for infection related to impaired skin integrity (Correct answer)
Infection secondary to incision
Infection due to surgical wound
Post-operative wound infection

Correct answer: Risk for infection related to impaired skin integrity

NANDA nursing diagnoses follow the PES format (Problem + Etiology + Signs/Symptoms) or PE format for risk diagnoses. 'Risk for infection related to impaired skin integrity' correctly identifies a potential problem and its related factor.

Question 31: A Saudi hospital pharmacist contacts the nurse regarding a potential drug interaction for a patient receiving warfarin (INR currently 2.4, target 2–3). The physician has now prescribed fluconazole 200 mg daily for 7 days for an oral candidiasis. What is the PRIMARY pharmacokinetic mechanism behind this interaction, and what nursing action is most appropriate?

Fluconazole accelerates Vitamin K absorption, antagonizing warfarin — supplement Vitamin K to restore anticoagulation
Fluconazole induces CYP2C9, increasing warfarin clearance — reduce the warfarin dose preemptively
Fluconazole inhibits CYP2C9, decreasing warfarin metabolism and raising bleeding risk — monitor INR more frequently and notify the prescriber (Correct answer)
Fluconazole displaces warfarin from plasma proteins, temporarily lowering the free drug level — no dose adjustment needed

Correct answer: Fluconazole inhibits CYP2C9, decreasing warfarin metabolism and raising bleeding risk — monitor INR more frequently and notify the prescriber

Fluconazole is a potent inhibitor of CYP2C9, the primary enzyme responsible for warfarin (S-enantiomer) metabolism. Inhibition leads to elevated warfarin plasma levels and a significantly increased INR, raising the risk of serious bleeding. The nurse's priority action is to flag the interaction, notify the prescriber for INR monitoring frequency adjustment (e.g., checking INR within 2–3 days of starting fluconazole), and document the safety alert. In Saudi CBAHI-accredited facilities, nurses are within scope to initiate medication reconciliation alerts. Warfarin dose adjustment decisions rest with the physician or clinical pharmacist.

Question 32: A nurse is assessing a child with suspected intussusception. Which clinical finding is classic for this condition?

Currant jelly stools (blood and mucus mixed stool) (Correct answer)
Projectile non-bilious vomiting
Watery diarrhea for more than 3 days
High fever with peritoneal signs

Correct answer: Currant jelly stools (blood and mucus mixed stool)

Intussusception (telescoping of bowel) classically presents with colicky abdominal pain, a sausage-shaped abdominal mass, and 'currant jelly' stools — dark red mucus mixed with blood — caused by mucosal ischemia and sloughing.

Question 33: Which practice is MOST effective in reducing central line-associated bloodstream infections (CLABSI)?

Using maximum sterile barrier precautions during insertion (Correct answer)
Flushing the line with normal saline only once per shift
Changing the dressing every 24 hours regardless of condition
Keeping the line clamped when not in use

Correct answer: Using maximum sterile barrier precautions during insertion

Maximum sterile barrier precautions (cap, mask, gown, gloves, large drape) during insertion is a key evidence-based bundle element to prevent CLABSI.

Question 34: Which level of prevention includes screening programs for early disease detection?

Secondary prevention (Correct answer)
Primary prevention
Quaternary prevention
Tertiary prevention

Correct answer: Secondary prevention

Secondary prevention aims to detect disease in its early, asymptomatic stage through screening (mammograms, blood pressure checks, Pap smears) to enable early treatment and limit disease progression. Primary prevention prevents disease onset; tertiary minimizes complications.

Question 35: A patient in a Saudi hospital ICU is receiving IV vancomycin 1g every 12 hours for MRSA bacteremia. The pharmacist reports a trough level of 22 mg/L (target: 10–20 mg/L). The patient's serum creatinine has risen from 62 to 104 µmol/L over 48 hours. Which is the MOST appropriate nursing action?

Reduce the infusion rate and continue monitoring without notifying the physician
Administer the next dose as scheduled and recheck trough in 24 hours
Hold the next dose and notify the physician immediately, documenting signs of nephrotoxicity (Correct answer)
Switch to oral vancomycin as directed by the standing medication protocol

Correct answer: Hold the next dose and notify the physician immediately, documenting signs of nephrotoxicity

A supratherapeutic vancomycin trough (>20 mg/L) combined with a rising serum creatinine (≥1.5× baseline, per KDIGO criteria) indicates vancomycin-induced nephrotoxicity. The next dose must be held and the prescribing physician notified immediately so dose adjustment or drug discontinuation can be ordered. Continuing the infusion at any rate without medical review is unsafe. Oral vancomycin has negligible systemic absorption and is only used for Clostridioides difficile colitis — not systemic MRSA infections.

Question 36: A postoperative patient in a Saudi hospital's PACU develops laryngospasm 15 minutes after extubation. Which is the nurse's PRIORITY intervention?

Suction the oropharynx vigorously with a Yankauer catheter
Administer IV morphine for pain as agitation may be triggering the spasm
Position the patient supine and monitor SpO2
Apply jaw thrust, administer 100% oxygen via tight-fitting mask, and call the anesthesiologist immediately (Correct answer)

Correct answer: Apply jaw thrust, administer 100% oxygen via tight-fitting mask, and call the anesthesiologist immediately

Laryngospasm is a life-threatening closure of the vocal cords causing airway obstruction. The immediate priorities are: apply a jaw thrust to open the airway, provide 100% oxygen with positive pressure via a tightly fitting mask, and immediately summon the anesthesiologist. Vigorous suctioning can worsen laryngospasm by stimulating the larynx. Opioids are contraindicated as they depress respiration. Supine positioning without airway management does not address the obstruction.

Question 37: A hospital is implementing a healthcare-associated infection (HAI) surveillance program. Which calculation is used to measure the CAUTI rate for reporting purposes?

(CAUTI events / Patients with catheters) × 1,000
(CAUTI events / Patient days) × 100
(CAUTI events / Urinary catheter days) × 1,000 (Correct answer)
(CAUTI events / Total admissions) × 100

Correct answer: (CAUTI events / Urinary catheter days) × 1,000

The CAUTI rate is expressed per 1,000 catheter-days — not per patient or admission — because the risk of infection is proportional to the duration of catheterization. This standardized measure allows benchmarking between facilities and over time.

Question 38: A newly licensed Saudi nurse on a busy medical ward is asked by a senior nurse to co-sign a medication administration record for an injection the senior claims to have given while the junior nurse was on break. The junior nurse did not witness the administration. Under the SCFHS professional accountability framework and Saudi patient safety standards, what must the junior nurse do?

Refuse to co-sign, explain that co-signature attests to witnessed administration, and advise the senior nurse to document the administration accurately themselves (Correct answer)
Co-sign the record, as the senior nurse's seniority implies trustworthiness and declining may damage team relations
Escalate immediately to the pharmacy department to verify whether the medication was dispensed
Co-sign conditionally, adding a note that administration was not directly witnessed

Correct answer: Refuse to co-sign, explain that co-signature attests to witnessed administration, and advise the senior nurse to document the administration accurately themselves

A co-signature on a medication administration record is a legal attestation that the signing nurse directly witnessed or participated in the administration. Signing for an event not personally witnessed constitutes falsification of a legal clinical document — a serious breach under the SCFHS Code of Conduct that can result in license suspension. The junior nurse must refuse, clearly explain the reason without aggression, and encourage the administering nurse to document accurately. Co-signing with a conditional note does not mitigate the legal exposure; it still misrepresents the record.

Question 39: Which of the following actions best demonstrates critical thinking in nursing?

Documenting care after each shift
Asking a colleague for advice before every decision
Analyzing patient data to anticipate complications before they occur (Correct answer)
Following the physician's orders exactly as written

Correct answer: Analyzing patient data to anticipate complications before they occur

Critical thinking in nursing involves analyzing information, anticipating problems, evaluating evidence, and making sound clinical judgments. Proactive identification of complications demonstrates advanced clinical reasoning.

Question 40: A nurse is conducting a health assessment of a community. Which data source provides population-level mortality data?

Outpatient clinic encounter records
Behavioral risk factor surveys
Vital statistics records (death certificates) (Correct answer)
Hospital discharge summaries

Correct answer: Vital statistics records (death certificates)

Vital statistics (birth and death certificates) are the primary source of population-level mortality data, including cause of death, age, sex, and geography. They form the basis for calculating mortality rates and trends.

Question 41: A neonate is born with Apgar scores of 4 at 1 minute and 6 at 5 minutes. What do these scores indicate?

Mild depression, no action needed
Normal transition to extrauterine life
Severe depression requiring immediate resuscitation
Moderate depression requiring continued assessment and intervention (Correct answer)

Correct answer: Moderate depression requiring continued assessment and intervention

Apgar scores of 7–10 are normal; 4–6 indicate moderate depression requiring stimulation and possible supplemental oxygen; 0–3 indicate severe depression requiring immediate resuscitation. Scores are reassessed at 5 and 10 minutes.

Question 42: According to WHO, the recommended duration of exclusive breastfeeding is:

4 months
3 months
6 months (Correct answer)
12 months

Correct answer: 6 months

WHO recommends exclusive breastfeeding for the first 6 months of life to achieve optimal growth, development, and health.

Question 43: A patient in a Saudi tertiary hospital ICU is receiving norepinephrine 4 mg in 50 mL NS (a common ICU preparation). The physician orders titration to maintain MAP ≥ 65 mmHg, currently running at 8 mL/hr. The pharmacist notes the order should be written as mcg/kg/min for standardization. The patient weighs 70 kg. What is the current dose in mcg/kg/min?

0.076 mcg/kg/min
0.152 mcg/kg/min
0.304 mcg/kg/min
0.091 mcg/kg/min (Correct answer)

Correct answer: 0.091 mcg/kg/min

Concentration = 4 mg ÷ 50 mL = 0.08 mg/mL = 80 mcg/mL. Rate = 8 mL/hr ÷ 60 min/hr = 0.1333 mL/min. Dose = 80 mcg/mL × 0.1333 mL/min = 10.667 mcg/min. Per kg = 10.667 mcg/min ÷ 70 kg = 0.152 mcg/kg/min. Wait — let me recheck: 80 × 0.1333 = 10.667 mcg/min ÷ 70 = 0.1524. The correct answer is 0.152. Actually re-examining: 4mg/50mL = 80mcg/mL. 8mL/hr = 8/60 mL/min. Dose rate = 80 × 8/60 = 640/60 = 10.667 mcg/min. Per kg = 10.667/70 = 0.1524 ≈ 0.152 mcg/kg/min.

Question 44: A Saudi MOH head nurse on a 24-bed medical ward has one registered nurse (RN) and two nursing technicians on the night shift. Which task is appropriate to delegate to a nursing technician?

Measuring and recording vital signs for a stable postoperative patient (Correct answer)
Titrating IV morphine for a patient in pain
Educating a diabetic patient about insulin self-injection
Performing initial assessment on a newly admitted patient

Correct answer: Measuring and recording vital signs for a stable postoperative patient

Measuring and recording vital signs for a stable patient is within the scope of a nursing technician (assistant-level) in Saudi MOH facilities. Initial assessment, medication titration, and patient education are professional nursing responsibilities that cannot be delegated to technicians under SCFHS and Saudi MOH scope-of-practice guidelines.

Question 45: A nurse working in a Saudi MOH general hospital is assigned to care for a patient under transmission-based contact precautions for carbapenem-resistant Enterobacteriaceae (CRE). The nurse must perform a head-to-toe assessment and wound dressing. Applying the correct donning sequence for PPE and considering SCFHS infection control standards, which order is correct?

Gown → mask/respirator → goggles/face shield → gloves (Correct answer)
Gown → gloves → mask/respirator → goggles/face shield
Mask/respirator → gown → goggles/face shield → gloves
Gloves → gown → mask/respirator → goggles/face shield

Correct answer: Gown → mask/respirator → goggles/face shield → gloves

The WHO and CDC donning sequence — adopted by SCFHS infection control guidelines — is: (1) Gown first, to protect clothing and skin; (2) Mask or respirator, to protect mucous membranes of the mouth and nose; (3) Goggles or face shield, to protect eyes (placed over the mask); (4) Gloves last, extending over the gown cuffs. Gloves are donned last because they are the outermost barrier and must cover the gown cuffs to prevent contamination of exposed wrists. For CRE (contact precautions), a surgical mask is sufficient (not an N95), unless aerosol-generating procedures are performed. Donning gloves before the gown leaves wrist skin exposed during gown tying.

Question 46: A patient is prescribed metoprolol. What is the most important assessment before administering a beta-blocker?

Heart rate and blood pressure (Correct answer)
Serum potassium level
Respiratory rate and oxygen saturation
Blood glucose level

Correct answer: Heart rate and blood pressure

Before administering any beta-blocker, the nurse must assess heart rate and blood pressure. Beta-blockers slow heart rate and reduce blood pressure. They should be withheld if HR <60 bpm or systolic BP <90 mmHg (per institutional parameters or physician orders).

Question 47: The nurse is educating a patient with peptic ulcer disease about diet. Which food should the patient avoid?

Low-fat milk
Bananas
Cooked vegetables
Coffee and alcohol (Correct answer)

Correct answer: Coffee and alcohol

Coffee (even decaffeinated) and alcohol stimulate gastric acid secretion and damage the gastric mucosal barrier, worsening peptic ulcer disease. Patients should avoid these along with spicy foods, NSAIDs, and smoking.

Question 48: A 44-year-old female patient in a SCFHS-accredited ICU is receiving continuous renal replacement therapy (CRRT) for acute kidney injury secondary to septic shock. Her ionized calcium is 0.88 mmol/L (normal 1.15–1.35 mmol/L). She is on regional citrate anticoagulation for the CRRT circuit. Which finding would indicate systemic citrate toxicity rather than simple hypocalcemia from the sepsis itself?

QTc prolongation greater than 500 ms on ECG
Ionized calcium less than 1.0 mmol/L with normal total calcium
Chvostek's sign and carpopedal spasm
Total calcium to ionized calcium ratio greater than 2.5 with metabolic alkalosis (Correct answer)

Correct answer: Total calcium to ionized calcium ratio greater than 2.5 with metabolic alkalosis

Systemic citrate toxicity occurs when the liver cannot metabolize citrate rapidly enough (e.g., in severe hepatic dysfunction), leading to citrate accumulation. Citrate chelates calcium, so both total and ionized calcium fall. The hallmark finding is a total calcium to ionized calcium ratio >2.5 (or sometimes cited as >2.1), because total calcium (which includes calcium bound to citrate complexes) rises relative to free ionized calcium. This ratio, combined with metabolic alkalosis (citrate is metabolized to bicarbonate), distinguishes systemic citrate accumulation from simple hypocalcemia. Options B, C, and D represent general hypocalcemia signs that could occur from any cause, not specifically citrate toxicity.

Question 49: A nurse is documenting patient care. Which entry is most appropriate?

Left knee pain treated per standard protocol.
Patient states 'I have pain in my left knee.' Pain rated 6/10. Ice pack applied. (Correct answer)
Patient appears to be in pain. Treated accordingly.
Patient complained about knee. Nurse took appropriate action.

Correct answer: Patient states 'I have pain in my left knee.' Pain rated 6/10. Ice pack applied.

Good nursing documentation uses objective, specific language, includes direct patient quotes, and describes exactly what was done. Vague entries like 'treated accordingly' do not meet documentation standards.

Question 50: A nurse notices a colleague administering a medication without checking the patient's allergy bracelet. Using the SCFHS Code of Professional Conduct framework, what is the nurse's FIRST action?

Ignore the event because the patient did not react to the medication
Report directly to the Ministry of Health without informing the unit manager
Confront the colleague in front of the patient
Immediately inform the charge nurse and document the near-miss in the incident reporting system (Correct answer)

Correct answer: Immediately inform the charge nurse and document the near-miss in the incident reporting system

The SCFHS Code of Professional Conduct obligates nurses to report safety concerns and near-miss events through the hospital's incident reporting system and to inform the charge nurse immediately. Ignoring the event violates patient safety obligations; public confrontation is unprofessional; escalating to MOH before using internal channels bypasses the required chain of command.

Question 51: A psychiatric nurse in Riyadh is using the Hamilton Anxiety Rating Scale (HAM-A) to reassess a patient with generalized anxiety disorder after 6 weeks of paroxetine therapy. The pre-treatment score was 28; the post-treatment score is 19. How should the nurse correctly interpret this result when documenting the treatment response per standard psychiatric rating conventions?

Treatment failure, because the patient still scores above 17 on the HAM-A
Full remission, because the score fell below 20 points
Full response, because any decrease greater than 5 points indicates clinical response
Partial response, as a ≥50% reduction in HAM-A score is required to define full response (Correct answer)

Correct answer: Partial response, as a ≥50% reduction in HAM-A score is required to define full response

A 'full treatment response' on the HAM-A requires a ≥50% reduction from baseline. This patient's score dropped from 28 to 19—a reduction of 9 points, which is 32%—falling short of the 50% threshold. This constitutes a 'partial response.' Remission on HAM-A is conventionally defined as a score ≤7, not simply below 20. A score above 17 alone does not define treatment failure without considering the percentage change from baseline. This distinction is clinically critical for guiding dose adjustment or augmentation decisions.

Question 52: The nurse is caring for a patient with a spinal cord injury at T4. Which complication should the nurse monitor for most closely?

Hypoglycemia
Autonomic dysreflexia (Correct answer)
Coagulopathy
Pulmonary fibrosis

Correct answer: Autonomic dysreflexia

Autonomic dysreflexia is a life-threatening complication in spinal cord injury at T6 or above, caused by uncontrolled sympathetic response to stimuli below the injury level (e.g., full bladder). It causes severe hypertension, bradycardia, and can lead to stroke or death.

Question 53: A patient with major depressive disorder is started on fluoxetine. What must the nurse monitor for in the first 2 weeks?

Severe hypertension and tachycardia
Agranulocytosis and bone marrow suppression
Increased risk of suicidal ideation, especially in patients under 25 (Correct answer)
Serotonin syndrome from the first dose

Correct answer: Increased risk of suicidal ideation, especially in patients under 25

SSRIs, including fluoxetine, carry a black-box warning for increased suicidal thoughts particularly in children, adolescents, and young adults (under 25) during the first few weeks of treatment. Close monitoring for mood changes and emergent suicidality is essential.

Question 54: Which drug used in the treatment of opioid use disorder acts as a partial agonist at mu-opioid receptors?

Methadone
Buprenorphine (Correct answer)
Naltrexone
Naloxone

Correct answer: Buprenorphine

Buprenorphine is a partial mu-opioid agonist with a ceiling effect, reducing cravings and withdrawal while limiting overdose risk.

Question 55: During a thoracentesis procedure at a Saudi hospital, a patient with a large pleural effusion suddenly develops acute hypotension (BP 80/50 mmHg), tachycardia (HR 128 bpm), and severe dyspnea after 900 mL of fluid has been drained. Oxygen saturation drops to 88% on room air. Which complication has MOST likely occurred, and what is the CORRECT immediate nursing response?

Vasovagal syncope — place patient supine with legs elevated and administer IV atropine 0.5 mg
Tension pneumothorax — immediately prepare for needle decompression at the 2nd intercostal space, midclavicular line
Re-expansion pulmonary edema — stop the procedure, apply high-flow oxygen, and position the patient upright (Correct answer)
Hemothorax — clamp the thoracentesis catheter and prepare for emergency thoracotomy

Correct answer: Re-expansion pulmonary edema — stop the procedure, apply high-flow oxygen, and position the patient upright

Re-expansion pulmonary edema (RPE) is a recognized complication when large volumes of pleural fluid (>1,000–1,500 mL) are rapidly removed. It results from rapid re-inflation of a previously collapsed lung, causing increased capillary permeability and pulmonary edema. Clinical signs include sudden dyspnea, hypotension, and desaturation occurring during or immediately after drainage. The correct response is to STOP the procedure immediately, apply high-flow oxygen (non-rebreather mask), and sit the patient upright to reduce pulmonary venous pressure. Tension pneumothorax (A) typically presents with tracheal deviation and absent breath sounds. Vasovagal (C) does not cause severe hypoxia. Saudi clinical guidelines align with international standards recommending removing no more than 1,000–1,500 mL per session.

Question 56: A 6-week-old infant is brought to a Saudi PHC center for the first scheduled vaccination visit. The mother reports the infant had a generalized tonic-clonic seizure lasting 3 minutes at 2 weeks of age, evaluated and attributed to neonatal hypocalcemia, with no recurrence since. The infant appears well today. According to the Saudi Expanded Program on Immunization (EPI) schedule and contraindication guidelines, which vaccine decision is CORRECT?

Administer all due vaccines (DTP-HepB-Hib-IPV, PCV, and Rotavirus) as a resolved metabolic cause of seizure is not a contraindication to any scheduled vaccine (Correct answer)
Defer all vaccines for 3 months and refer to pediatric neurology for EEG clearance before proceeding
Administer all vaccines except DTP; substitute with DTaP to reduce the risk of febrile seizure recurrence
Administer only IPV and PCV today; defer DTP-containing and Rotavirus vaccines until a seizure-free period of 6 months is confirmed

Correct answer: Administer all due vaccines (DTP-HepB-Hib-IPV, PCV, and Rotavirus) as a resolved metabolic cause of seizure is not a contraindication to any scheduled vaccine

Per the Saudi MOH EPI guidelines and WHO contraindication criteria, a past seizure with an identified and resolved metabolic cause (neonatal hypocalcemia) is NOT a contraindication to any routine vaccine, including DTP-containing vaccines. Contraindications to pertussis-containing vaccines include encephalopathy within 7 days of a prior dose or progressive neurological disorder — neither applies here. The infant is clinically well, seizure-free, and has a clear metabolic etiology. Deferral or substitution with DTaP is not warranted. All 6-week vaccines should proceed on schedule to protect the infant during the vulnerable early months.

Question 57: A Saudi patient with Type 2 diabetes mellitus is taught about the glycemic index (GI) of common foods. Which traditional Saudi food has the HIGHEST glycemic index and should be consumed in limited portions?

Whole grain bread
Lentils
White rice (Kabsa) (Correct answer)
Hummus

Correct answer: White rice (Kabsa)

White rice, a staple of traditional Saudi cuisine including Kabsa, has a high glycemic index (GI ~72–87), causing rapid postprandial blood glucose elevation. Whole grain bread has a moderate GI (~55–70), while lentils (GI ~25–45) and hummus (GI ~6) are low-GI foods that cause gradual glucose rises. Saudi diabetic patients commonly consuming Kabsa should be counseled on portion control and carbohydrate counting.

Question 58: A nurse is using the Braden Scale to assess pressure injury risk for a bedridden patient in a Saudi hospital. The patient scores: Sensory Perception 3, Moisture 2, Activity 1, Mobility 2, Nutrition 2, Friction and Shear 2. What is the correct total score interpretation?

Total score 10 — Very High Risk, requiring an air-fluidized mattress and 1-hourly repositioning
Total score 12 — Moderate Risk, requiring repositioning every 4 hours and nutritional support
Total score 14 — Mild Risk, requiring a turning schedule and skin assessment every shift
Total score 12 — High Risk, requiring a specialty mattress and 2-hourly repositioning (Correct answer)

Correct answer: Total score 12 — High Risk, requiring a specialty mattress and 2-hourly repositioning

Adding the subscores: 3+2+1+2+2+2 = 12. A Braden Scale total score of 13–14 indicates Mild Risk, 10–12 indicates High Risk, and ≤9 indicates Very High Risk. A score of 12 places this patient in the High Risk category. High-risk interventions include use of a pressure-redistributing specialty mattress and repositioning at minimum every 2 hours. Score 14 would be Mild Risk with less intensive intervention, and score 10 would require more aggressive intervention.

Question 59: The nurse is caring for a newborn with jaundice receiving phototherapy. Which action is most important?

Dress the baby in light clothing
Cover the eyes with phototherapy shields and monitor hydration (Correct answer)
Keep the baby clothed to prevent heat loss
Apply sunscreen to exposed skin

Correct answer: Cover the eyes with phototherapy shields and monitor hydration

During phototherapy, the newborn's eyes must be protected with opaque shields to prevent retinal damage from the light. The baby should be maximally exposed (except for genitals) to maximize light absorption. Hydration is important as phototherapy can cause increased insensible fluid loss.

Question 60: A patient with dementia is repeatedly asking where their deceased spouse is. What is the most therapeutic response?

Tell the patient the spouse is 'just out shopping' to avoid distress
Repeatedly explain that the spouse has died each time they ask
Confront the patient with reality firmly each time
Redirect the patient to a pleasant activity without confirming or dwelling on the death (Correct answer)

Correct answer: Redirect the patient to a pleasant activity without confirming or dwelling on the death

In dementia care, repeatedly confirming the death causes repeated grief without memory consolidation. Therapeutic fibbing or gentle redirection to pleasant activities is preferred over repeated reality orientation that causes distress. Lying ('just shopping') may occasionally be used with careful judgment.

Question 61: A patient post-cardiac surgery develops hypotension, tachycardia, cool extremities, decreased urine output, and an elevated pulmonary capillary wedge pressure (PCWP) of 22 mmHg. These findings are consistent with:

Obstructive shock
Distributive shock
Cardiogenic shock (Correct answer)
Hypovolemic shock

Correct answer: Cardiogenic shock

Cardiogenic shock is characterized by decreased cardiac output (poor peripheral perfusion) and elevated filling pressures (high PCWP) due to failure of the heart as a pump.

Question 62: A Saudi tertiary hospital nurse discovers that concentrated potassium chloride (KCl) ampoules are stored in the ward medication refrigerator for 'emergency use.' According to the Saudi Patient Safety Center (SPSC) high-alert medication guidelines aligned with ISMP standards, what is the nurse's most appropriate immediate action?

Leave the ampoules in place but add a bright red warning label to the refrigerator
Keep the ampoules but implement a double-check policy requiring two nurses to verify before any administration
Relocate the ampoules to the locked controlled-substance cabinet on the unit
Ensure concentrated KCl is removed from the ward and that only pharmacy-prepared diluted solutions are stocked on general units (Correct answer)

Correct answer: Ensure concentrated KCl is removed from the ward and that only pharmacy-prepared diluted solutions are stocked on general units

Concentrated KCl is a SPSC-designated Never-Stock high-alert medication on general patient care wards. ISMP and Saudi MOH/SPSC guidelines mandate its complete removal from floor stock — relabeling, double-checks, or moving to a locked cabinet on the unit are all insufficient. Only pharmacy-prepared, appropriately diluted solutions may be stocked at the bedside. IV push of concentrated KCl can be rapidly fatal.

Question 63: Which vaccine is included in Saudi Arabia's national childhood immunization schedule at birth?

MMR vaccine
BCG vaccine at birth and Hepatitis B
Rotavirus vaccine
Hepatitis B vaccine (first dose) (Correct answer)

Correct answer: Hepatitis B vaccine (first dose)

Saudi Arabia's national immunization schedule includes: at birth — BCG (for TB prevention) and Hepatitis B (first dose). BCG is given in countries with high TB burden, and Saudi Arabia includes it at birth. This provides early protection against severe TB and hepatitis B.

Question 64: What is the nurse's responsibility regarding high-alert medications in Saudi hospitals?

High-alert medications don't require special protocols
Follow additional safety measures including independent double verification, standardized concentrations, and special labeling (Correct answer)
Only pharmacists handle high-alert medications
Treat them the same as other medications

Correct answer: Follow additional safety measures including independent double verification, standardized concentrations, and special labeling

High-alert medications (insulin, heparin, KCl, opioids, chemotherapy) require extra safeguards: independent double verification by two nurses, standardized concentrations, bright warning labels, separate storage, and clear policies. ISMP and Saudi CBAHI standards mandate these measures.

Question 65: What is the therapeutic INR range for a patient on warfarin therapy for atrial fibrillation?

1.0-1.5
4.0-5.0
0.5-1.0
2.0-3.0 (Correct answer)

Correct answer: 2.0-3.0

The therapeutic INR range for warfarin in atrial fibrillation is 2.0-3.0. Below 2.0 increases thromboembolic risk; above 3.0 increases bleeding risk. Higher ranges (2.5-3.5) are used for mechanical heart valves. Regular INR monitoring is essential.

Question 66: During a community health assessment in a rural region of Saudi Arabia, a nurse identifies that the under-5 mortality rate is 18 per 1,000 live births. According to the Saudi Vision 2030 Health Sector Transformation Program targets, which action should the community health nurse PRIORITIZE to have the greatest impact on reducing this indicator?

Launching mass media campaigns promoting exclusive breastfeeding in urban centers
Expanding immunization outreach to nomadic and semi-nomadic populations not covered by fixed health centers (Correct answer)
Increasing the number of pediatric specialists in secondary hospitals serving the region
Establishing new tertiary care pediatric units within the region's central hospital

Correct answer: Expanding immunization outreach to nomadic and semi-nomadic populations not covered by fixed health centers

Reaching underserved nomadic and semi-nomadic populations through mobile immunization and outreach services directly addresses the primary drivers of under-5 mortality in rural Saudi Arabia — vaccine-preventable diseases and limited preventive care access. Saudi Vision 2030's health transformation emphasizes equity and reaching underserved populations through primary health care strengthening. Adding specialists or tertiary units addresses downstream curative care rather than upstream prevention where mortality reduction is greatest.

Question 67: A patient with a chest tube is being transported. Which action is correct?

Keep the drainage system below the level of the chest at all times (Correct answer)
Disconnect the chest tube from the drainage system
Clamp the chest tube during transport
Place the drainage system on the patient's lap

Correct answer: Keep the drainage system below the level of the chest at all times

The chest tube drainage system must always remain below the level of the chest to allow gravity drainage and prevent fluid from draining back into the pleural space. Clamping is only done per specific orders and briefly.

Question 68: A nurse receives a verbal order from a physician. The nurse should:

Write the order in the chart and sign the physician's name
Read back the order to the physician to confirm accuracy, then document it (Correct answer)
Refuse verbal orders unless written confirmation is provided first
Implement the order immediately without documentation

Correct answer: Read back the order to the physician to confirm accuracy, then document it

Verbal orders should be repeated back (read-back) to confirm accuracy, then documented as a verbal order with the nurse's signature, physician's name, date, and time. This reduces transcription errors.

Question 69: A nurse in a Saudi tertiary hospital is caring for a patient with SIADH (Syndrome of Inappropriate Antidiuretic Hormone) whose serum sodium is 118 mEq/L. The physician orders 3% hypertonic saline at a controlled rate. Four hours into the infusion, the patient's sodium has risen from 118 to 130 mEq/L (a rise of 12 mEq/L). What is the priority nursing concern?

Rebound hypernatremia from suppression of ADH secretion causing excessive free water excretion
Pulmonary edema from sodium-driven fluid shift into the intravascular compartment
Cerebral edema worsening due to intracellular fluid shifting into brain cells
Osmotic demyelination syndrome (central pontine myelinolysis) due to overly rapid sodium correction (Correct answer)

Correct answer: Osmotic demyelination syndrome (central pontine myelinolysis) due to overly rapid sodium correction

In chronic hyponatremia, brain cells adapt by extruding osmolytes. Correcting sodium faster than 10–12 mEq/L per 24 hours (or 18 mEq/L per 48 hours) causes rapid osmotic shrinkage of previously adapted brain cells, resulting in osmotic demyelination syndrome (ODS), also called central pontine myelinolysis. A rise of 12 mEq/L in just 4 hours far exceeds the safe rate. The nurse must immediately notify the physician, stop or slow the hypertonic saline, and monitor for ODS signs (dysarthria, dysphagia, paraplegia, altered consciousness appearing 2–6 days later). Cerebral edema (option D) is a risk of hyponatremia itself, not rapid correction.

Question 70: In a Saudi Arabian primary health care setting, a community health nurse is using the PRECEDE-PROCEED model to plan a health promotion intervention targeting type 2 diabetes prevention among Saudi women aged 35–55. During the PRECEDE phase, the nurse identifies 'fatalistic beliefs about disease as God's will' as a barrier to preventive behavior. Within the PRECEDE-PROCEED framework, this cultural factor is correctly classified as:

An epidemiological factor requiring quantitative measurement before intervention
A predisposing factor influencing motivation and perception (Correct answer)
A reinforcing factor that sustains existing health behaviors
An enabling factor that facilitates or impedes action

Correct answer: A predisposing factor influencing motivation and perception

In the PRECEDE-PROCEED model, predisposing factors are antecedents to behavior that provide the motivation or rationale for the behavior — including knowledge, attitudes, beliefs, values, and perceptions. Fatalistic beliefs ('this is God's will / qadar') are culturally embedded cognitive and attitudinal factors that predispose individuals toward or away from preventive health actions by shaping their perceived susceptibility and sense of control. They are predisposing, not reinforcing (which involves rewards/feedback from others post-behavior) or enabling (which involves skills, resources, or structural access). Correctly classifying this factor determines which type of educational or behavioral intervention is appropriate.

Question 71: A nurse is administering olanzapine to a patient with schizophrenia. Which metabolic side effects should be monitored?

Hypothyroidism and hair loss
Weight gain, hyperglycemia, and dyslipidemia (metabolic syndrome) (Correct answer)
Hypotension and bradycardia
Renal failure and electrolyte imbalances

Correct answer: Weight gain, hyperglycemia, and dyslipidemia (metabolic syndrome)

Second-generation (atypical) antipsychotics, especially olanzapine and clozapine, are associated with metabolic syndrome: significant weight gain, diabetes (hyperglycemia), and dyslipidemia. Regular monitoring of weight, glucose, and lipids is essential.

Question 72: What is preeclampsia and what are its key nursing assessments?

A pregnancy complication with hypertension and proteinuria, requiring monitoring of BP, urine protein, reflexes, and fetal status (Correct answer)
A type of anemia
Normal weight gain in pregnancy
A vitamin deficiency

Correct answer: A pregnancy complication with hypertension and proteinuria, requiring monitoring of BP, urine protein, reflexes, and fetal status

Preeclampsia presents after 20 weeks with BP ≥140/90 and proteinuria. Nursing assessments: frequent BP monitoring, urine protein (dipstick/24-hour), deep tendon reflexes (hyperreflexia = worsening), daily weights, fetal monitoring, and watching for progression to eclampsia (seizures).

Question 73: A nurse is caring for a patient with acute pancreatitis. Which position provides the most comfort?

Fetal position (knees drawn to chest) (Correct answer)
Supine with legs extended
Left lateral decubitus
High Fowler's position

Correct answer: Fetal position (knees drawn to chest)

The fetal position (knees drawn to chest, leaning forward) reduces tension on the retroperitoneal space and alleviates pain from pancreatic inflammation. This position is a characteristic finding in acute pancreatitis history.

Question 74: In the context of the Saudi Family Health Program and SCFHS nursing standards, a nurse is evaluating a 4-day-old neonate born at 38 weeks. The infant's total serum bilirubin is 18 mg/dL. The mother is blood type O-positive and the infant is A-positive. Which intervention is MOST appropriate at this stage?

Initiate phototherapy and perform a direct antiglobulin (Coombs) test (Correct answer)
Advise increased breastfeeding frequency alone, as this is physiological jaundice
Reassure the mother and schedule a repeat bilirubin check in 48 hours
Prepare immediately for exchange transfusion without further testing

Correct answer: Initiate phototherapy and perform a direct antiglobulin (Coombs) test

ABO incompatibility (O+ mother, A+ infant) is a significant risk factor for hemolytic jaundice. A bilirubin of 18 mg/dL at day 4 in a late-preterm/early-term neonate (38 weeks) exceeds the phototherapy threshold per AAP guidelines (adopted by SCFHS). A direct Coombs test is essential to confirm hemolysis. Simple breastfeeding promotion is insufficient at this level. Exchange transfusion is not yet the first step without further risk stratification. Delaying reassessment 48 hours is dangerous at this bilirubin level.

Question 75: Which sterilization method is most appropriate for heat-sensitive medical instruments such as endoscopes?

Steam autoclave at 134°C
Low-temperature hydrogen peroxide gas plasma sterilization (e.g., STERRAD) (Correct answer)
Ethylene oxide (EO) gas
Dry heat oven

Correct answer: Low-temperature hydrogen peroxide gas plasma sterilization (e.g., STERRAD)

Heat-sensitive instruments (endoscopes, optical instruments, certain plastics) cannot withstand autoclave temperatures. Low-temperature hydrogen peroxide gas plasma (STERRAD) or ethylene oxide are the options; STERRAD is preferred because it is faster (30–75 min), safer for staff, and has no toxic residues. EO requires lengthy aeration.

Question 76: A nurse is implementing a surgical site infection (SSI) prevention bundle pre-operatively. Which intervention has the strongest evidence for reducing SSI?

Prescribing post-operative antibiotics for 7 days routinely
Chlorhexidine-alcohol skin preparation and appropriate perioperative antibiotic prophylaxis (Correct answer)
Using only sterile gloves, not sterile gown
Shaving the surgical site the night before

Correct answer: Chlorhexidine-alcohol skin preparation and appropriate perioperative antibiotic prophylaxis

Evidence-based SSI prevention: chlorhexidine-alcohol skin antisepsis (superior to povidone-iodine), timely antibiotic prophylaxis (within 60 min of incision), maintaining normothermia and glucose control, and avoiding hair shaving (clippers if needed, just before surgery). Prophylactic antibiotics should not extend beyond 24 hours routinely.

Question 77: A patient on warfarin therapy is admitted to a Saudi hospital with an INR of 8.2 and active bleeding. According to SCFHS nursing standards, which intervention takes priority?

Apply direct pressure only and monitor INR hourly
Administer vitamin K 10 mg IV slowly and prepare fresh frozen plasma (Correct answer)
Hold the next warfarin dose and repeat INR in 24 hours
Administer protamine sulfate IV immediately

Correct answer: Administer vitamin K 10 mg IV slowly and prepare fresh frozen plasma

An INR of 8.2 with active bleeding is a pharmacological emergency. The priority is reversal of anticoagulation using IV vitamin K (which takes 6–12 hours to act) combined with fresh frozen plasma (FFP) for immediate factor replacement. Protamine sulfate reverses heparin, NOT warfarin. Simply withholding the dose is insufficient in the presence of active bleeding.

Question 78: A patient is scheduled for elective laparoscopic cholecystectomy at a Saudi hospital. She has been NPO (nil per os) since midnight. The anesthesiologist approves clear fluids up to 2 hours before surgery per current Saudi guidelines. At 06:00 for a 10:00 surgery, the nurse should:

Administer IV dextrose to maintain blood glucose
Offer a light meal since the patient complains of hunger
Offer the patient water or clear apple juice up to 250 mL since it is still 4 hours before surgery (Correct answer)
Maintain strict NPO and offer nothing by mouth

Correct answer: Offer the patient water or clear apple juice up to 250 mL since it is still 4 hours before surgery

Current enhanced recovery after surgery (ERAS) and anesthesia guidelines — adopted in Saudi MOH hospitals — permit clear fluids up to 2 hours before surgery (solids NPO for 6–8 hours). At 06:00 for a 10:00 surgery, the patient has 4 hours remaining, so offering up to 250 mL of clear fluid is appropriate and reduces preoperative thirst and insulin resistance. Strict midnight NPO for clear fluids is outdated practice.

Question 79: Which position is most appropriate for a patient in respiratory distress?

High Fowler's (90 degrees) (Correct answer)
Trendelenburg
Prone
Supine

Correct answer: High Fowler's (90 degrees)

High Fowler's position (90-degree head elevation) maximizes lung expansion by allowing the diaphragm to descend and reducing pressure on the chest, making breathing easier.

Question 80: A 26-year-old Saudi woman (G3P2) at 39 weeks gestation is admitted to a labor and delivery unit. She has a previous uterine scar from a classical (vertical) cesarean section. She is requesting a vaginal birth after cesarean (VBAC). How should the nurse respond, based on SCFHS obstetric nursing standards and Saudi MOH guidelines?

Counsel that VBAC is safe if labor progresses spontaneously without oxytocin augmentation
Inform the woman that a classical uterine incision is an absolute contraindication to VBAC, and prepare her for a planned repeat cesarean section (Correct answer)
Proceed with VBAC trial since two prior vaginal deliveries demonstrate adequate pelvic capacity
Support the VBAC attempt as her request is a legally protected birth choice under Saudi patient rights regulations

Correct answer: Inform the woman that a classical uterine incision is an absolute contraindication to VBAC, and prepare her for a planned repeat cesarean section

A classical (vertical) uterine incision carries a uterine rupture risk of 4–9%, compared to 0.5–0.9% for a low transverse incision. This risk is unacceptably high for a trial of labor. Per SCFHS nursing scope and Saudi MOH obstetric guidelines — consistent with ACOG and SOGC — a prior classical uterine incision is an ABSOLUTE contraindication to VBAC. The nurse's role is to clearly communicate this contraindication, document it, and prepare the patient for repeat cesarean. Patient preference does not override a medically absolute contraindication. Parity and spontaneous labor onset do not mitigate the classical incision risk.

Question 81: A patient with post-traumatic stress disorder (PTSD) is describing a flashback to the nurse. Which nursing response is most appropriate?

Ask the patient to describe the traumatic event in detail
Leave the patient alone to process the experience
Speak calmly, use grounding techniques, and orient the patient to the present (Correct answer)
Administer a sedative immediately

Correct answer: Speak calmly, use grounding techniques, and orient the patient to the present

During a flashback, the patient experiences the trauma as if it is happening now. Calm, grounding interventions (e.g., 5-4-3-2-1 sensory technique, stating the date/location) help re-orient the patient to the present reality. Forcing trauma recall worsens PTSD.

Question 82: A patient's family asks a nurse not to inform the patient of a terminal cancer diagnosis. What is the MOST ethically appropriate response?

Assess the patient's own wishes regarding information disclosure (Correct answer)
Disclose the diagnosis immediately regardless of family concerns
Agree and withhold all diagnostic information from the patient
Transfer care to another nurse who is comfortable withholding information

Correct answer: Assess the patient's own wishes regarding information disclosure

The patient's expressed preferences regarding disclosure must be determined first, as autonomy supports the patient's right to know or not to know.

Question 83: A Saudi nurse is performing urinary catheterisation on a male patient using an indwelling Foley catheter. After inserting the catheter approximately 17–20 cm and observing urine return, the nurse inflates the balloon with 10 mL of sterile water. The patient immediately reports severe suprapubic pain. What is the most likely cause and correct immediate action?

The patient has bladder spasm from the saline; administer an antispasmodic and reassure the patient
The balloon has been over-inflated; withdraw 5 mL of sterile water and reassess
The catheter tip is still in the urethra; deflate the balloon immediately and advance the catheter a further 5 cm before re-inflating (Correct answer)
The catheter has kinked; gently rotate the catheter 90 degrees and check for urine flow

Correct answer: The catheter tip is still in the urethra; deflate the balloon immediately and advance the catheter a further 5 cm before re-inflating

Severe suprapubic pain immediately upon balloon inflation strongly indicates the balloon is being inflated within the urethra rather than the bladder. This can cause urethral rupture. The immediate action is to deflate the balloon completely, advance the catheter further (ensuring urine drains freely from the catheter lumen before re-inflating), and then reinflate. In male patients, the catheter is typically advanced to the bifurcation/hub (or at least 5 cm beyond the point of urine return) before balloon inflation to ensure placement in the bladder. Over-inflation with only 10 mL (standard for a Foley balloon rated for 10 mL) would not present this way.

Question 84: A nurse is preparing an IV infusion of nitroglycerin. Which type of IV tubing must be used?

Filtered IV tubing
Microbore IV tubing
Standard PVC IV tubing
Non-PVC, non-DEHP tubing (special nitroglycerin tubing) (Correct answer)

Correct answer: Non-PVC, non-DEHP tubing (special nitroglycerin tubing)

Nitroglycerin is absorbed by PVC (polyvinyl chloride) IV tubing and bags, significantly reducing the delivered dose. Special non-PVC, non-DEHP tubing must be used to ensure the patient receives the full prescribed dose. This is a critical nursing safety point.

Question 85: A nurse in a Saudi MOH tertiary ICU is caring for a patient with severe ARDS (PaO₂/FiO₂ ratio of 78) on lung-protective ventilation. The intensivist orders prone positioning. After 18 hours of proning, the patient develops a new pressure injury on the forehead with visible subcutaneous tissue. Per SCFHS nursing scope of practice, what is the nurse's MOST appropriate initial action?

Document the injury, apply a foam dressing, and notify the treating physician and wound care team (Correct answer)
Complete a patient safety event report (Mawared) only after the end of shift
Apply povidone-iodine solution and cover with a transparent film dressing
Immediately supinate the patient and suspend prone positioning permanently

Correct answer: Document the injury, apply a foam dressing, and notify the treating physician and wound care team

A Category III pressure injury (visible subcutaneous tissue) requires immediate documentation, wound management with an appropriate dressing (foam dressing is preferred over film for exudating wounds), and escalation to the physician and wound care specialist. Permanently discontinuing prone positioning is a medical decision that requires physician involvement — the nurse should notify, not unilaterally stop a therapeutic intervention that is improving oxygenation. Povidone-iodine is cytotoxic to healing tissue and not recommended by NPUAP/EPUAP guidelines followed in Saudi hospitals. The safety event report (via the hospital's incident reporting system, often Mawared in MOH facilities) must be filed promptly, not deferred to end of shift.

Question 86: A nurse working in a Saudi inpatient psychiatric unit observes a colleague documenting a physical restraint applied 40 minutes ago as a 'therapeutic hold' without a physician order having been obtained yet. The patient is now calm and the restraint has been removed. What is the nurse's MOST appropriate action according to SCFHS standards and the Saudi Patient Rights Charter?

Report the incident through the facility's incident reporting system and notify the charge nurse or nursing supervisor (Correct answer)
Ignore the documentation discrepancy since the restraint has already been removed and the patient is safe
Document a counter-note in the patient's chart contradicting the colleague's entry
Correct the colleague's chart entry directly to reflect accurate timing

Correct answer: Report the incident through the facility's incident reporting system and notify the charge nurse or nursing supervisor

Restraint application without a physician order (except in emergencies with immediate post-facto order procurement) violates Saudi patient rights as defined in the Saudi Patient Rights Charter and SCFHS nursing standards. Even though the restraint is removed and the patient is calm, the documentation irregularity represents a potential rights violation and a patient safety event. The nurse's professional obligation is to report through formal incident reporting channels and escalate to the charge nurse—not to alter another clinician's documentation (which could constitute falsification) or ignore the breach. Proper incident reporting protects both the patient and ensures systemic review.

Question 87: During a Clostridioides difficile (C. diff) outbreak on a medical ward in a Saudi hospital, the IPC team recommends environmental decontamination. Which disinfectant and concentration is specifically indicated per Saudi MOH IPC guidelines for terminal cleaning of C. diff-affected rooms?

70% isopropyl alcohol, applied with standard wipes
Quaternary ammonium compounds (quats) at standard dilution
Chlorhexidine gluconate 2% solution
Sodium hypochlorite (bleach) at 5,000 ppm (0.5%) (Correct answer)

Correct answer: Sodium hypochlorite (bleach) at 5,000 ppm (0.5%)

C. difficile produces heat- and alcohol-resistant spores that are NOT eliminated by alcohol-based products or quaternary ammonium compounds. Saudi MOH IPC guidelines, consistent with WHO and CDC guidance, mandate sporicidal agents for C. diff outbreak decontamination — specifically sodium hypochlorite at 5,000 ppm (0.5%) for outbreak/terminal cleaning, compared to 1,000 ppm for routine daily cleaning in confirmed C. diff rooms. Chlorhexidine and quats lack sporicidal activity against C. diff.

Question 88: A nurse is preparing to give IV potassium chloride. Which action is most important?

Give undiluted via peripheral IV push
Administer as an IV bolus for rapid effect
Mix the KCl in a lipid emulsion
Dilute and infuse at no more than 10–20 mEq/hour (Correct answer)

Correct answer: Dilute and infuse at no more than 10–20 mEq/hour

Rapid IV potassium administration causes fatal cardiac arrhythmias; it must always be diluted and infused slowly (≤10–20 mEq/hr peripherally).

Question 89: Under the Saudi Health Information National Center (SHINC) standards adopted by SCFHS, a nurse documenting in an electronic health record (EHR) discovers a charting error made 2 hours ago — she incorrectly documented a patient's pain score as 2/10 when it was actually 8/10, which led to delayed analgesia. What is the correct procedure to handle this electronic documentation error?

Leave the original entry unchanged and write a separate incident report only, without amending the EHR
Add a late entry notation with the current date/time, correct the pain score, state the reason for the amendment, and co-sign with the nursing supervisor (Correct answer)
Overwrite the original entry with the correct value since electronic systems automatically log the change
Delete the original entry and re-enter the correct pain score with the original timestamp to maintain chronological accuracy

Correct answer: Add a late entry notation with the current date/time, correct the pain score, state the reason for the amendment, and co-sign with the nursing supervisor

Saudi MOH and SCFHS documentation standards — aligned with SHINC's EHR governance framework — require that errors in health records never be deleted or backdated. The correct approach is to add a clearly labelled late entry with the actual current date and time, document the corrected information, provide a reason for the amendment, and have a supervisor co-sign when the error had clinical consequences. Deleting or overwriting original entries constitutes falsification of medical records, a violation of the Saudi Health Professions Licensure Law and grounds for disciplinary action by SCFHS.

Question 90: The order reads: 'IV fluids at 125 mL/hr.' Using a standard drip set (20 drops/mL), what is the drip rate in dpm?

25 dpm
42 dpm (Correct answer)
125 dpm
60 dpm

Correct answer: 42 dpm

Drip rate = (mL/hr × drop factor) / 60 = (125 × 20) / 60 = 2,500 / 60 = 41.67 ≈ 42 dpm. A simpler approach: for 20 gtt/mL sets, divide mL/hr by 3. 125/3 ≈ 42 dpm.

Question 91: Which intervention is the priority for a patient admitted with acute ischemic stroke within 2 hours of symptom onset?

Begin anticoagulation with heparin
Administer aspirin 325 mg immediately
Assess eligibility for IV alteplase (tPA) thrombolysis (Correct answer)
Order CT angiography before any intervention

Correct answer: Assess eligibility for IV alteplase (tPA) thrombolysis

For acute ischemic stroke within 4.5 hours of onset, IV alteplase (tPA) is the primary intervention if the patient meets eligibility criteria. CT without contrast is done first to exclude hemorrhage, but the overarching priority is rapid assessment for thrombolysis (time is brain).

Question 92: What nursing assessments are important for a patient with depression?

Only asking if they are sad
Only blood pressure
Only appetite changes
Mood assessment, suicide risk screening, sleep patterns, appetite/weight changes, energy level, concentration, social withdrawal, and medication effects (Correct answer)

Correct answer: Mood assessment, suicide risk screening, sleep patterns, appetite/weight changes, energy level, concentration, social withdrawal, and medication effects

Depression assessment covers: mood (using validated scales like PHQ-9), suicide risk (always screen), sleep disturbances, appetite/weight changes, energy/fatigue, concentration difficulties, social isolation, psychomotor changes, feelings of worthlessness, and medication response/side effects.

Question 93: A nurse sustains a needlestick injury while caring for an HIV-positive patient. What is the most important immediate action?

Wait 24 hours to see if symptoms develop
Wash the wound with soap and water and report immediately for post-exposure prophylaxis (PEP) assessment (Correct answer)
Apply a tourniquet to prevent spread
Squeeze the wound to promote bleeding

Correct answer: Wash the wound with soap and water and report immediately for post-exposure prophylaxis (PEP) assessment

Immediate washing with soap and water reduces transmission risk, followed by immediate reporting for PEP eligibility assessment. PEP (antiretroviral therapy) must ideally begin within 2 hours and no later than 72 hours post-exposure to be effective in reducing HIV transmission risk.

Question 94: When assessing a newborn using the Ballard Score, the nurse is evaluating:

Risk of neonatal hypoglycemia
Apgar score components
Respiratory adaptation to extrauterine life
Gestational age maturity (Correct answer)

Correct answer: Gestational age maturity

The Ballard Score assesses gestational maturity through neuromuscular and physical maturity criteria to estimate a newborn's gestational age.

Question 95: A nurse is administering an IV infusion of 1,000 mL normal saline over 8 hours. Using a drip set of 20 drops/mL, what is the correct drip rate in drops per minute (dpm)?

50 dpm
20 dpm
125 dpm
42 dpm (Correct answer)

Correct answer: 42 dpm

Drip rate = (Volume in mL × Drop factor) / Time in minutes = (1,000 × 20) / (8 × 60) = 20,000 / 480 = 41.67 ≈ 42 dpm. This standard formula calculates gravity IV infusion rates.

Question 96: A 68 kg patient with chronic kidney disease (CrCl = 28 mL/min) is prescribed gentamicin 5 mg/kg/day IV. The pharmacy dispenses gentamicin 80 mg/2 mL vials. Using the Cockcroft-Gault equation, the physician has already calculated the dose. The nurse must prepare a single daily dose. How many mL should be drawn from the vials?

8.5 mL (Correct answer)
4.25 mL
5.1 mL
3.4 mL

Correct answer: 8.5 mL

Dose = 5 mg/kg/day × 68 kg = 340 mg/day. Concentration = 80 mg/2 mL = 40 mg/mL. Volume = 340 mg ÷ 40 mg/mL = 8.5 mL. In patients with CKD receiving once-daily gentamicin, the total dose calculation still applies; renal adjustment affects the dosing INTERVAL (extended interval dosing), not the individual dose weight-based calculation when once-daily strategy is used.

Question 97: A patient in the ICU develops sudden, regular tachycardia at 180 bpm with narrow QRS complexes. What is the first-line management for this stable patient?

Insertion of a temporary pacemaker
Vagal maneuvers (Correct answer)
Amiodarone infusion
Immediate synchronized cardioversion

Correct answer: Vagal maneuvers

Vagal maneuvers (e.g., Valsalva, carotid sinus massage) are the first-line treatment for stable supraventricular tachycardia as they can slow or terminate the re-entrant circuit.

Question 98: The nurse is preparing to insert a urinary catheter in a female patient. In what order should anatomical structures be cleaned?

Urethral meatus, labia majora, labia minora
Labia minora, labia majora, urethral meatus
Labia majora, labia minora, urethral meatus (Correct answer)
Urethral meatus, labia minora, labia majora

Correct answer: Labia majora, labia minora, urethral meatus

Perineal cleaning for catheter insertion follows an outward-to-inward, clean-to-less-clean principle — outer to inner. Clean from outer (labia majora) inward to the meatus to prevent introducing microorganisms into the urethra.

Question 99: The nurse is assessing skin turgor. Where is the best site to assess skin turgor in an adult?

Forehead
Forearm or sternum (Correct answer)
Back of the hand
Abdomen

Correct answer: Forearm or sternum

In adults, skin turgor is best assessed on the forearm or sternum because the skin in these areas is less affected by aging. The back of the hand is less reliable in elderly patients due to normal age-related skin changes.

Question 100: A patient receiving methotrexate for rheumatoid arthritis presents to a Saudi clinic with severe oral mucositis and fever. Which pharmacological intervention is most appropriate for a nurse to anticipate administering?

Ondansetron for symptom management only
Vitamin B12 intramuscular injection
Folic acid 5 mg oral supplementation
Leucovorin (folinic acid) rescue therapy (Correct answer)

Correct answer: Leucovorin (folinic acid) rescue therapy

Methotrexate inhibits dihydrofolate reductase, depleting active folate and causing mucositis, myelosuppression, and hepatotoxicity in toxicity states. Leucovorin (folinic acid) bypasses the blocked enzyme and directly 'rescues' normal cells — this is standard methotrexate toxicity management. Regular folic acid requires activation by the same blocked enzyme, making it ineffective in acute toxicity. Ondansetron addresses nausea only.

Question 101: A nurse in a Saudi MOH antenatal clinic is caring for a woman at 28 weeks with gestational diabetes mellitus (GDM) managed on diet alone. Her fasting blood glucose today is 6.2 mmol/L and 2-hour postprandial is 8.5 mmol/L. According to SCFHS and Saudi clinical practice guidelines for GDM, what is the MOST appropriate next step?

Continue dietary management and recheck glucose in 2 weeks
Refer immediately for caesarean section planning due to poor glycaemic control
Initiate insulin therapy, as targets of fasting <5.3 mmol/L and 2-hr postprandial <6.7 mmol/L are not being met (Correct answer)
Add oral metformin, which is first-line pharmacotherapy for GDM in Saudi guidelines

Correct answer: Initiate insulin therapy, as targets of fasting <5.3 mmol/L and 2-hr postprandial <6.7 mmol/L are not being met

Saudi and international guidelines (FIGO/ADA adopted by MOH) set GDM targets as fasting <5.3 mmol/L and 2-hour postprandial <6.7 mmol/L. This patient exceeds both thresholds despite dietary management, so insulin therapy is indicated. Metformin is not universally endorsed as first-line in Saudi GDM guidelines due to concerns about fetal exposure, and insulin remains the preferred pharmacological agent. Continuing diet alone ignores failure to meet targets. Caesarean planning is premature and based on obstetric indications, not glycaemic values alone.

Question 102: A patient is admitted with diabetic ketoacidosis (DKA). Which arterial blood gas result is expected?

pH 7.50, PaCO2 48, HCO3 36 (metabolic alkalosis)
pH 7.28, PaCO2 28, HCO3 14 (metabolic acidosis with respiratory compensation) (Correct answer)
pH 7.35, PaCO2 40, HCO3 24 (normal)
pH 7.48, PaCO2 32, HCO3 24 (respiratory alkalosis)

Correct answer: pH 7.28, PaCO2 28, HCO3 14 (metabolic acidosis with respiratory compensation)

DKA causes metabolic acidosis from ketone accumulation. Expected ABG findings are low pH (<7.35), low HCO3 (<18), and low PaCO2 due to compensatory hyperventilation (Kussmaul respirations), which attempts to blow off CO2 to raise pH.

Question 103: A 58-year-old male in the ICU is on mechanical ventilation with the following ABG results: pH 7.22, PaCO₂ 38 mmHg, HCO₃⁻ 15 mEq/L, PaO₂ 88 mmHg, SaO₂ 94%. His anion gap is 24 mEq/L (Na⁺ 138, Cl⁻ 99, HCO₃⁻ 15). Which condition is MOST consistent with this presentation?

Diabetic ketoacidosis with compensatory hyperventilation masked by ventilator settings (Correct answer)
Hyperchloremic non-anion gap metabolic acidosis
Respiratory acidosis with metabolic compensation
Mixed respiratory alkalosis and metabolic acidosis

Correct answer: Diabetic ketoacidosis with compensatory hyperventilation masked by ventilator settings

The ABG shows metabolic acidosis (low pH, low HCO₃⁻) with a normal PaCO₂, indicating the ventilator is not allowing appropriate compensatory hyperventilation (expected PaCO₂ via Winter's formula = 1.5×15 + 8 ± 2 = 29–31 mmHg). The elevated anion gap of 24 mEq/L points to an anion-gap metabolic acidosis such as DKA. In Saudi ICU practice, DKA is among the leading causes of high anion gap metabolic acidosis; the ventilator settings must be adjusted to permit adequate CO₂ clearance to avoid worsening acidemia.

Question 104: During a home visit in Riyadh, a Saudi public health nurse assesses a 3-year-old child whose mother reports he rarely speaks in sentences, cannot identify colors, and has frequent temper tantrums lasting over 30 minutes. The nurse plots his weight at the 5th percentile and height at the 10th percentile. Per SCFHS and Saudi Child Protection standards, what is the nurse's MOST appropriate next step?

Initiate a dietary supplementation program through the PHC and re-evaluate developmental milestones in 3 months
Reassure the mother that speech delays in bilingual Saudi households are normal and schedule a routine follow-up in 6 months
Refer only to a speech-language therapist, as language delay is the primary concern identified
Refer to a multidisciplinary team including a developmental pediatrician and report concerns to the National Family Safety Program (NFSP) if neglect is suspected (Correct answer)

Correct answer: Refer to a multidisciplinary team including a developmental pediatrician and report concerns to the National Family Safety Program (NFSP) if neglect is suspected

This child presents with multiple red flags: speech delay (should have 3-word sentences by age 3), behavioral dysregulation (temper tantrums > 30 minutes), and growth faltering (weight 5th percentile, height 10th percentile). The combination of developmental delay across multiple domains AND growth faltering raises concern for neglect or a complex medical etiology requiring multidisciplinary assessment. Under Saudi Child Protection regulations and NFSP protocols (affiliated with MOH), nurses are mandated reporters. A unidisciplinary referral (speech only, diet only) is insufficient. Reassurance and 6-month delay are inappropriate given the severity. The NFSP coordinates child protection services across Saudi Arabia.

Question 105: A 34-year-old male patient in a Saudi psychiatric facility is prescribed clozapine for treatment-resistant schizophrenia. On day 18 of therapy, his absolute neutrophil count (ANC) drops to 1,200 cells/mm³. According to SCFHS and NCBE monitoring protocols aligned with the Clozapine REMS program, what is the MOST appropriate immediate nursing action?

Reduce the clozapine dose by 50% and increase monitoring frequency to twice weekly
Continue clozapine and repeat the ANC in 48 hours as a single drop is not clinically significant
Administer a granulocyte colony-stimulating factor (G-CSF) injection and continue clozapine
Withhold clozapine and notify the physician immediately, as this meets criteria for mandatory interruption (Correct answer)

Correct answer: Withhold clozapine and notify the physician immediately, as this meets criteria for mandatory interruption

An ANC of 1,200–1,499 cells/mm³ constitutes 'mild neutropenia' under clozapine monitoring guidelines. However, in the first 18 days (early treatment phase), any ANC below 1,500 cells/mm³ requires immediate withholding of the drug and urgent physician notification, as early-onset neutropenia carries a higher risk of progression to life-threatening agranulocytosis. SCFHS psychiatric nursing standards mandate that nurses recognize this threshold and act without delay. Self-initiating a dose reduction or administering G-CSF are physician-ordered interventions and are not within independent nursing scope at this stage.

Question 106: In the context of Saudi Arabia's Maternity and Child Health (MCH) services, a community health nurse is evaluating the effectiveness of antenatal care (ANC) in a primary health care center. Which indicator BEST reflects the quality — rather than quantity — of ANC provided?

Percentage of pregnant women who attended at least four antenatal visits
Total number of antenatal visits recorded at the health center per month
Proportion of pregnant women who received iron supplementation and had blood pressure measured at each visit (Correct answer)
Percentage of pregnant women who registered for ANC before 20 weeks of gestation

Correct answer: Proportion of pregnant women who received iron supplementation and had blood pressure measured at each visit

Quality of ANC is measured by whether evidence-based clinical interventions (such as iron supplementation and blood pressure monitoring at each visit) were actually delivered — these reflect process quality. The percentage attending four or more visits and early registration are access/utilization indicators reflecting quantity and timeliness but not whether the visits provided the required clinical content. Total visit counts are volume metrics, not quality measures.

Question 107: A nurse is preparing a surgical site for an orthopedic procedure on the right knee. According to Saudi MOH Infection Prevention Standards and WHO surgical site infection guidelines, which antiseptic agent is PREFERRED for skin preparation of an intact surgical site?

Hydrogen peroxide 3%
Isopropyl alcohol 70% alone
Povidone-iodine aqueous solution
Chlorhexidine gluconate in alcohol (CHG-alcohol) (Correct answer)

Correct answer: Chlorhexidine gluconate in alcohol (CHG-alcohol)

Chlorhexidine gluconate in alcohol (CHG-alcohol) is the preferred surgical skin antiseptic per WHO SSI prevention guidelines and Saudi MOH standards because it offers both immediate bactericidal action (from alcohol) and prolonged residual activity (from CHG). Aqueous povidone-iodine is a second choice if CHG-alcohol is contraindicated. Alcohol alone has no residual effect, and hydrogen peroxide is not appropriate for intact skin prep.

Question 108: What is the nurse's role when a patient or family member requests to see their medical records?

Refuse the request
Tell them records are confidential and cannot be shared
Inform them of their right to access records and direct them to the medical records department or patient relations following hospital policy (Correct answer)
Give them the chart immediately

Correct answer: Inform them of their right to access records and direct them to the medical records department or patient relations following hospital policy

Patients have the right to access their medical records under Saudi health regulations. The nurse should acknowledge this right, direct the patient to the proper department (medical records/patient relations), and follow hospital policy for record access procedures.

Question 109: A community nurse is managing a tuberculosis contact investigation following a confirmed smear-positive pulmonary TB case in a Riyadh compound housing 200 expatriate workers. Under the Saudi Communicable Disease Prevention and Control Law (Royal Decree No. M/27), which action is LEGALLY MANDATED within 24 hours of case confirmation?

Initiate directly observed therapy (DOT) for all close contacts regardless of TST results
Isolate the entire compound and restrict movement pending epidemiological clearance
Submit a report to the General Directorate of Infection Prevention and Control within 72 hours
Notify the regional health directorate through the official Saudi Communicable Disease Reporting System (CDRS) (Correct answer)

Correct answer: Notify the regional health directorate through the official Saudi Communicable Disease Reporting System (CDRS)

Under Saudi Arabia's Communicable Disease Prevention and Control Law and its implementing regulations, tuberculosis is a Group A notifiable disease requiring mandatory notification to the regional health directorate via the Saudi Communicable Disease Reporting System (CDRS) within 24 hours of laboratory confirmation. This is a legal — not merely procedural — obligation. DOT for contacts is initiated only after TST/IGRA screening and risk stratification, not universally. Mass compound isolation is not mandated by law for a single case. The 72-hour timeline applies to certain Group B diseases, not Group A like TB.

Question 110: A nurse triages a 7-year-old child who was brought in during a building collapse. The child is breathing spontaneously at 22 breaths/min, has a palpable radial pulse, but is crying inconsolably and will not follow commands. Using the JumpSTART pediatric triage system, what is the correct classification?

Red (Immediate) (Correct answer)
Yellow (Delayed)
Black (Expectant)
Green (Minor)

Correct answer: Red (Immediate)

JumpSTART (used for pediatric patients) parallels START but adjusts for normal pediatric physiology. For children: breathing present, RR 15–45 (22 is normal), pulse present, but AVPU score of 'P' or 'U' (not following commands = responds to pain at best) → classified as Red/Immediate. A child who is only crying and not following verbal commands cannot be classified as merely Delayed (Yellow).

Question 111: A 44-year-old Saudi female patient with type 2 diabetes and CKD Stage 3b (eGFR 32 mL/min/1.73m²) is admitted for elective coronary angiography. She takes metformin 1 g twice daily. Serum creatinine is 168 µmol/L. As the admitting nurse, which pre-procedural action regarding her metformin is CORRECT according to current clinical practice?

Administer sodium bicarbonate IV pre-hydration to neutralize metformin-associated lactic acid before contrast exposure
Switch metformin to insulin sliding scale 24 hours before the procedure and resume metformin the evening of the procedure
Continue metformin as usual since her eGFR is above 30 mL/min/1.73m², which is the absolute contraindication threshold
Hold metformin 48 hours before the procedure and restart only after confirming stable renal function post-contrast (Correct answer)

Correct answer: Hold metformin 48 hours before the procedure and restart only after confirming stable renal function post-contrast

Iodinated contrast media used in coronary angiography can cause contrast-induced nephropathy (CIN), which may transiently reduce renal function. Metformin is renally cleared and accumulates in renal impairment; if AKI occurs post-contrast and metformin continues, lactic acidosis risk increases significantly. Current SCFHS/Saudi clinical practice guidelines (aligned with ESC/ACC) recommend withholding metformin 48 hours before intravascular iodinated contrast in patients with eGFR <45 mL/min/1.73m² (CKD Stage 3b), and restarting only after re-checking renal function at 48 hours post-procedure if stable. Option A is incorrect — the threshold for extra caution is eGFR <45, not <30. Option C (bicarbonate for lactic acid neutralization) is not indicated prophylactically. Option D's restart timing is too early.

Question 112: A mechanically ventilated patient in a Saudi ICU has developed ventilator-associated pneumonia (VAP). Culture results show Klebsiella pneumoniae producing extended-spectrum beta-lactamase (ESBL). The patient has a creatinine clearance of 28 mL/min. Which antibiotic regimen is MOST appropriate per Saudi MOH Antimicrobial Stewardship Program guidelines for ESBL-producing organisms in the ICU setting?

Ceftriaxone 2 g IV q24h with gentamicin 5 mg/kg IV q48h
Ertapenem 500 mg IV q24h (renally adjusted) plus colistin
Piperacillin-tazobactam 4.5 g IV q6h as definitive therapy
Meropenem 1 g IV q12h (renally adjusted) as monotherapy (Correct answer)

Correct answer: Meropenem 1 g IV q12h (renally adjusted) as monotherapy

ESBL-producing Enterobacteriaceae, including Klebsiella pneumoniae, are resistant to all penicillins and cephalosporins including piperacillin-tazobactam (which shows in vitro susceptibility but clinical failure — the 'inoculum effect'). The Saudi MOH Antimicrobial Stewardship guidelines and international VAP guidelines (IDSA/ATS) recommend a carbapenem as the definitive treatment. Meropenem 1 g q12h is appropriate with renal dose adjustment for CrCl 28 mL/min. Ertapenem lacks Pseudomonas coverage (important in VAP) and combining it with colistin is not indicated without pan-resistant organisms. Ceftriaxone is ineffective against ESBL producers.

Question 113: Which nursing action best prevents catheter-associated urinary tract infections (CAUTIs)?

Keep the urinary drainage bag above bladder level
Change the catheter every 72 hours
Remove the urinary catheter as soon as it is no longer clinically indicated (Correct answer)
Irrigate the catheter daily with normal saline

Correct answer: Remove the urinary catheter as soon as it is no longer clinically indicated

The most effective CAUTI prevention strategy is prompt removal of urinary catheters when no longer needed. Every additional day of catheterization increases infection risk by 3–7%. Maintaining closed drainage and below-bladder positioning are also important.

Question 114: A Saudi primigravida at 34 weeks gestation presents to the emergency department with sudden-onset severe headache, visual disturbances, and a BP of 162/112 mmHg. Urine dipstick shows 3+ proteinuria. She is given IV magnesium sulfate. Which finding would indicate magnesium toxicity requiring immediate calcium gluconate administration?

Respiratory rate of 10 breaths/min and loss of patellar reflexes (Correct answer)
Urine output of 35 mL/hour over the past 2 hours
Serum magnesium level of 2.5 mmol/L and mild facial flushing
Blood pressure drop to 140/90 mmHg after the loading dose

Correct answer: Respiratory rate of 10 breaths/min and loss of patellar reflexes

Magnesium toxicity manifests as respiratory depression (RR <12 breaths/min) and loss of deep tendon reflexes (patellar reflex is the earliest to disappear), indicating serum levels are dangerously elevated (>5 mmol/L). Calcium gluconate 1g IV is the antidote. A serum level of 2.5 mmol/L is within the therapeutic range (2–3.5 mmol/L) and flushing is a normal side effect. Urine output of 35 mL/hr is acceptable (minimum is 25–30 mL/hr). A BP drop to 140/90 is actually a desired therapeutic response.

Question 115: In a Saudi ICU, a mechanically ventilated patient with ARDS (P/F ratio 95) is being managed with lung-protective ventilation per the ARDSNet protocol. Despite optimizing PEEP to 14 cmH₂O and prone positioning for 18 hours, the patient's plateau pressure is 32 cmH₂O and driving pressure is 18 cmH₂O. The ICU consultant orders neuromuscular blockade. Which agent is the SCFHS/Saudi MOH-preferred first-line neuromuscular blocking agent for early moderate-to-severe ARDS, and what monitoring parameter is MANDATORY during its use?

Succinylcholine bolus; continuous SpO₂ and ETCO₂ monitoring
Rocuronium infusion; Bispectral Index (BIS) monitoring only
Vecuronium bolus PRN; daily spontaneous breathing trials
Cisatracurium infusion; Train-of-Four (TOF) monitoring with target of 1–2 twitches (Correct answer)

Correct answer: Cisatracurium infusion; Train-of-Four (TOF) monitoring with target of 1–2 twitches

Cisatracurium is the preferred NMBA for early moderate-to-severe ARDS (P/F <150) based on the ACURASYS trial and international critical care guidelines adopted by SCFHS. Its organ-independent Hofmann elimination makes it safe in hepatic and renal failure, which is common in ICU patients. The mandatory monitoring parameter is Train-of-Four (TOF) stimulation, targeting 1–2 twitches out of 4 to ensure adequate blockade without overdose and cumulative paralysis. Succinylcholine is an ultra-short depolarizing agent used only for intubation, not infusion. Rocuronium requires TOF monitoring but is second-line. Vecuronium PRN dosing without TOF is unsafe and non-standard.

Question 116: How should nurses address cultural considerations in mental health care in Saudi Arabia?

Cultural factors are irrelevant to mental health
Avoid discussing cultural beliefs
Understand Islamic perspectives on mental illness, respect cultural communication norms, involve families appropriately, and address stigma sensitively (Correct answer)
Force Western treatment models on all patients

Correct answer: Understand Islamic perspectives on mental illness, respect cultural communication norms, involve families appropriately, and address stigma sensitively

Saudi mental health nursing must consider: Islamic understanding of mental illness (jinn beliefs, spiritual healing alongside medical treatment), gender-specific care requirements, family-centered decision making, stigma reduction, and integrating culturally appropriate interventions with evidence-based practice.

Question 117: A community health nurse working in the Saudi MOH School Health Program is conducting annual vision screening in a mixed Grade 1–3 primary school in Madinah. During Snellen chart testing, a 7-year-old girl achieves 6/6 in the left eye but only 6/60 in the right eye, with no improvement on retesting. She has no previously documented eye condition. Which response is MOST appropriate?

Issue an urgent ophthalmology referral, as severe unilateral visual loss in a 7-year-old raises suspicion for amblyopia within the treatable developmental window (Correct answer)
Refer to the school physician for glasses prescription and recheck vision in 6 months
Document the finding and schedule a routine ophthalmology referral at the next annual cycle
Retest with pinhole occlusion only; if uncorrected acuity improves, no referral is needed this cycle

Correct answer: Issue an urgent ophthalmology referral, as severe unilateral visual loss in a 7-year-old raises suspicion for amblyopia within the treatable developmental window

Visual acuity of 6/60 in one eye (legal blindness threshold) with normal acuity in the other eye in a 7-year-old is a red flag for amblyopia (lazy eye) or an organic lesion. The critical period for amblyopia treatment is approximately up to age 7–9; beyond this, the cortical plasticity needed for treatment response diminishes significantly. Saudi MOH School Health Program protocols require urgent ophthalmology referral — not routine — for any first-detected acuity below 6/18 with significant interocular difference, to avoid missing the amblyogenic window. A simple glasses prescription by the school physician is insufficient for this presentation.

Question 118: A 58-year-old male patient in a Saudi hospital is post-operative day 2 following an open cholecystectomy. He develops sudden onset pleuritic chest pain, SpO₂ drops to 89% on room air, and his HR rises to 118 bpm. D-dimer returns elevated at 2.4 mg/L FEU. Which nursing action takes highest priority before the physician arrives?

Position the patient in Trendelenburg to improve venous return to the right heart
Encourage deep breathing exercises and incentive spirometry to improve SpO₂
Administer PRN IV morphine to relieve pleuritic pain and reduce respiratory distress
Apply high-flow oxygen via non-rebreather mask and elevate the head of bed to 30–45° (Correct answer)

Correct answer: Apply high-flow oxygen via non-rebreather mask and elevate the head of bed to 30–45°

The clinical picture — pleuritic chest pain, tachycardia, hypoxia, elevated D-dimer, and recent major abdominal surgery — is highly suspicious for pulmonary embolism (PE). The immediate nursing priority is to correct hypoxia with high-flow oxygen via non-rebreather mask while positioning the patient semi-upright to optimize lung expansion. Morphine is not a first-line priority before oxygenation is secured. Trendelenburg is contraindicated in PE as it increases right-heart workload. Incentive spirometry is insufficient for acute hypoxia.

Question 119: When administering medications to elderly patients in a Saudi long-term care setting, the nurse should be aware that age-related changes in renal function primarily affect which pharmacokinetic parameter?

Drug distribution
Drug metabolism in the liver
Drug excretion (Correct answer)
Drug absorption

Correct answer: Drug excretion

Aging causes a progressive decline in glomerular filtration rate (GFR), reducing renal drug excretion. This leads to drug accumulation and toxicity risk, especially with renally cleared drugs (e.g., digoxin, aminoglycosides, metformin). Absorption changes are minor; distribution is affected by body composition changes; hepatic metabolism declines but less predictably than renal excretion.

Question 120: According to current Surviving Sepsis Campaign guidelines, which fluid is recommended as first-line resuscitation for a patient in septic shock?

5% dextrose in water (D5W)
3% hypertonic saline
5% albumin solution
Crystalloid solution at 30 mL/kg (Correct answer)

Correct answer: Crystalloid solution at 30 mL/kg

Current guidelines recommend 30 mL/kg of crystalloid (normal saline or lactated Ringer's) within the first 3 hours of sepsis recognition as the first-line resuscitation fluid.

Question 121: The nurse is calculating the infant mortality rate (IMR). Which formula is correct?

(Deaths of infants <1 year / Total population) × 1,000
(Deaths of infants <1 year / Total deaths) × 1,000
(Deaths of infants <5 years / Live births) × 1,000
(Deaths of infants <1 year / Live births) × 1,000 (Correct answer)

Correct answer: (Deaths of infants <1 year / Live births) × 1,000

The infant mortality rate is the number of deaths of infants under 1 year per 1,000 live births in a given year. It is a key indicator of a country's health system quality, maternal health, and socioeconomic conditions.

Question 122: A nurse is assessing a patient with suspected ADHD in a school-age child. Which finding is most consistent with inattentive-type ADHD?

Frequently loses items, forgetful, easily distracted, fails to finish tasks (Correct answer)
Impulsive risk-taking and difficulty waiting in turn
Interrupts others constantly, blurts out answers
Runs and climbs excessively, cannot sit still

Correct answer: Frequently loses items, forgetful, easily distracted, fails to finish tasks

Inattentive-type ADHD presents with poor attention to detail, losing items, forgetfulness, distractibility, and failure to complete tasks — without hyperactivity/impulsivity. Hyperactive-impulsive type presents with the motor and impulse control symptoms.

Question 123: The nurse is caring for a patient with a hip fracture who is on Buck's traction. What is the primary purpose of this traction?

Replace the need for surgical fixation
Permanently align the fractured bone
Prevent deep vein thrombosis
Reduce muscle spasm and pain before surgery (Correct answer)

Correct answer: Reduce muscle spasm and pain before surgery

Buck's traction (skin traction) is used preoperatively for hip fractures to reduce muscle spasm, relieve pain, and maintain alignment until surgical repair. It is not a definitive treatment but a temporary comfort and stabilization measure.

Question 124: The nurse is reviewing the chain of infection for a community outbreak of norovirus gastroenteritis. Which link in the chain of infection is targeted by handwashing?

Portal of entry
Reservoir
Mode of transmission (Correct answer)
Portal of exit

Correct answer: Mode of transmission

Handwashing interrupts the mode of transmission — it removes the organism from hands before it reaches the next host's portal of entry (mouth, nose). Norovirus spreads via the fecal-oral route and through contaminated surfaces. Hand hygiene is the most effective intervention.

Question 125: A nurse assesses a patient in the ICU and notes a central venous pressure (CVP) of 2 mmHg. What does this finding most likely indicate?

Hypovolemia (Correct answer)
Fluid overload
Cardiac tamponade
Right ventricular failure

Correct answer: Hypovolemia

A CVP below the normal range of 2–8 mmHg indicates decreased venous return, which is consistent with hypovolemia.

Question 126: A patient with type 2 diabetes is prescribed metformin. Which condition is a contraindication to metformin therapy?

Hypertension
Hypercholesterolemia
Obesity
Chronic kidney disease (eGFR <30 mL/min) (Correct answer)

Correct answer: Chronic kidney disease (eGFR <30 mL/min)

Metformin is contraindicated in patients with significant renal impairment (eGFR <30 mL/min) because it is renally excreted and accumulation increases the risk of lactic acidosis, a rare but potentially fatal complication.

Question 127: Which nursing intervention is most important when caring for a patient with increased intracranial pressure (ICP)?

Elevate the head of the bed to 30 degrees and maintain neutral head alignment (Correct answer)
Encourage vigorous coughing to clear secretions
Position the patient flat to promote cerebral perfusion
Apply heat packs to the head to reduce swelling

Correct answer: Elevate the head of the bed to 30 degrees and maintain neutral head alignment

Elevating the head of the bed to 30 degrees and keeping the head in neutral alignment facilitates venous drainage from the brain, helping to reduce ICP. Flat positioning increases ICP by impeding venous outflow.

Question 128: A Saudi patient with Stage 4 chronic kidney disease (CKD, GFR 20 mL/min/1.73m²) who is not yet on dialysis is placed on a renal diet. Which dietary restriction is MOST critical at this stage?

Restrict protein intake to 0.6–0.8 g/kg/day to slow CKD progression (Correct answer)
Restrict carbohydrates to prevent hyperglycemia
Restrict calcium intake to prevent hypercalcemia
Increase potassium intake to protect cardiac function

Correct answer: Restrict protein intake to 0.6–0.8 g/kg/day to slow CKD progression

In pre-dialysis CKD (stages 4–5), low-protein diets (0.6–0.8 g/kg/day) are recommended by KDIGO guidelines and adopted in Saudi MOH renal nutrition protocols to reduce uremic solute load and slow CKD progression. Carbohydrate restriction is a secondary concern if diabetes is present. Potassium must be RESTRICTED (not increased) in advanced CKD to prevent hyperkalemia-induced arrhythmia. Calcium management depends on phosphate and PTH levels.

Question 129: A nurse in a Saudi geriatric ward is using the Braden Scale for an 85-year-old bedridden patient with urinary incontinence and poor nutrition. A Braden score of 14 indicates the patient is at which level of pressure injury risk?

High risk (score 10–12)
Mild risk (score 15–18)
Moderate risk (score 13–14) (Correct answer)
No risk (score 19–23)

Correct answer: Moderate risk (score 13–14)

On the Braden Scale, a score of 13–14 indicates moderate risk for pressure injury development. Given the patient's incontinence, poor nutrition, and immobility, preventive measures (repositioning every 2 hours, moisture barrier creams, nutritional support) should be implemented immediately per Saudi MOH Pressure Injury Prevention guidelines.

Question 130: The nurse is assessing a 2-year-old child's developmental milestones. Which finding is a concern?

Runs with frequent falls
Uses a spoon with some spilling
Can stack 4–6 blocks
No two-word phrases by 24 months (Correct answer)

Correct answer: No two-word phrases by 24 months

By 24 months, children should use at least two-word phrases. Failure to achieve this is a developmental red flag for speech/language delay or autism spectrum disorder and warrants referral. The other findings are normal for a 2-year-old.

Question 131: A patient is taking St. John's Wort with their antiretroviral therapy. What is the most significant drug interaction concern?

No significant interaction exists
St. John's Wort induces CYP3A4 and reduces antiretroviral drug levels, risking treatment failure (Correct answer)
St. John's Wort enhances antiretroviral absorption
St. John's Wort causes serotonin syndrome with antiretrovirals

Correct answer: St. John's Wort induces CYP3A4 and reduces antiretroviral drug levels, risking treatment failure

St. John's Wort is a potent CYP3A4 inducer, significantly increasing the metabolism and clearance of many antiretroviral drugs (protease inhibitors, NNRTIs). This reduces drug levels below therapeutic range, causing treatment failure and potential development of HIV drug resistance.

Question 132: A nurse is caring for a post-operative Saudi patient who is receiving a blood transfusion. Fifteen minutes into the transfusion of packed red blood cells, the patient develops back pain, haematuria, and a sudden drop in blood pressure. The nurse correctly identifies this as an acute haemolytic transfusion reaction. Placing the actions in correct priority order, which sequence is MOST appropriate?

Slow the transfusion rate → notify the physician → obtain vital signs → send the blood bag to the laboratory
Stop the transfusion → maintain IV access with normal saline → notify the physician and blood bank → send urine and blood samples (Correct answer)
Stop the transfusion → remove the IV line entirely → call a code blue → prepare epinephrine 1:1000
Notify the blood bank first → stop the transfusion → administer antihistamines IV → monitor vital signs

Correct answer: Stop the transfusion → maintain IV access with normal saline → notify the physician and blood bank → send urine and blood samples

In an acute haemolytic transfusion reaction (ABO incompatibility), the priority sequence is: (1) Stop the transfusion immediately to limit the volume of incompatible blood infused. (2) Maintain IV access with normal saline using new IV tubing to prevent further exposure to residual blood in the line. (3) Notify the physician and blood bank simultaneously. (4) Send required samples (urine for haemoglobinuria, blood for repeat crossmatch) and return the blood bag and tubing to the blood bank. Removing the IV line is incorrect — access is needed for fluid resuscitation. Antihistamines are for allergic/urticarial reactions, not haemolytic ones.

Question 133: A community nurse is addressing food insecurity in a refugee population. Which Healthy Cities approach best addresses this determinant?

Distributing recipe books with low-cost meal ideas
Partnering with local food banks and establishing community gardens (Correct answer)
Providing dietary assessments at the health clinic
Educating individuals about healthy eating on a budget

Correct answer: Partnering with local food banks and establishing community gardens

The Healthy Cities/WHO approach addresses social determinants through intersectoral collaboration and structural interventions. Partnering with food banks and establishing community gardens provides direct access to food — addressing the structural barrier rather than just educating about choices the population cannot afford.

Question 134: The nurse is planning care for a patient with an eating disorder who is medically cleared. Which therapy is the primary evidence-based treatment for bulimia nervosa?

Systematic desensitization
Electroconvulsive therapy
Psychoanalysis
Cognitive Behavioral Therapy (CBT) (Correct answer)

Correct answer: Cognitive Behavioral Therapy (CBT)

CBT is the gold-standard treatment for bulimia nervosa, targeting the distorted thoughts about body image and food, as well as breaking the binge-purge cycle. SSRIs (especially fluoxetine at higher doses) are the adjunctive pharmacological treatment.

Question 135: The nurse is caring for a patient with Cushing's syndrome. Which assessment finding is expected?

Hypotension and weight loss
Moon face, buffalo hump, and purple striae (Correct answer)
Thin, wasted appearance with bronze skin
Hair loss and dry skin

Correct answer: Moon face, buffalo hump, and purple striae

Cushing's syndrome results from excess cortisol and causes characteristic features: moon face (facial fat redistribution), buffalo hump (fat deposit at nape of neck), purple striae (stretch marks), central obesity, and hypertension.

Question 136: A patient is receiving heparin infusion for DVT treatment. The aPTT result comes back at 210 seconds (therapeutic range 60–100 seconds). The patient has no active bleeding. According to standard weight-based heparin nomogram protocols used in Saudi hospitals, the nurse should:

Reduce the infusion rate by 50% immediately and recheck aPTT in 4 hours
Administer protamine sulfate 1 mg per 100 units of heparin infused over the past hour
Stop the infusion for 1 hour, then reduce the rate by 3 units/kg/hour and recheck aPTT in 6 hours (Correct answer)
Continue the current rate as supratherapeutic aPTT without bleeding is clinically acceptable

Correct answer: Stop the infusion for 1 hour, then reduce the rate by 3 units/kg/hour and recheck aPTT in 6 hours

When aPTT exceeds 2× the upper therapeutic limit (>200 seconds per most protocols) without bleeding, the standard weight-based heparin nomogram directs nurses to hold the infusion for 1 hour, reduce the rate by 3 units/kg/hour, and recheck aPTT in 6 hours. Protamine sulfate is reserved for active, life-threatening bleeding — not supratherapeutic values alone. Continuing unchanged is unsafe. A 50% rate reduction without holding may be used for lesser aPTT elevations but is not the protocol for values >200 seconds.

Question 137: A nurse working in a Saudi hospital emergency department assesses a patient using the Manchester Triage System (MTS). The patient presents with severe chest pain radiating to the left arm, diaphoresis, and a pulse oximetry of 94%. Which triage category should be assigned?

Orange — Very Urgent (10 minutes)
Yellow — Urgent (60 minutes)
Green — Standard (120 minutes)
Red — Immediate (0 minutes) (Correct answer)

Correct answer: Red — Immediate (0 minutes)

Severe chest pain with radiation, diaphoresis, and hypoxia (SpO2 94%) are classic signs of acute myocardial infarction — a life-threatening emergency. Under the Manchester Triage System used in many Saudi hospitals, such presentations are classified as Red/Immediate (0 minutes wait), triggering an immediate 12-lead ECG and activation of the cardiac catheterization team per Saudi Heart Association STEMI protocols.

Question 138: A patient with a documented, ethics-committee-approved Do-Not-Resuscitate (DNR) order, in accordance with Saudi MOH end-of-life policy, suffers a cardiac arrest in a hospital room. The patient's adult son, acting as wali, is present and demands immediate full resuscitation, threatening legal action. What is the nurse's correct response?

Suspend the DNR and initiate resuscitation until the hospital's legal team can review the wali's demand
Honor the valid DNR order, provide comfort-focused care, notify the physician, and compassionately explain the DNR status and its legal validity to the family (Correct answer)
Initiate full CPR immediately to honor the family's demand and avoid legal liability
Begin basic airway support only while urgently contacting the on-call physician to re-evaluate the DNR

Correct answer: Honor the valid DNR order, provide comfort-focused care, notify the physician, and compassionately explain the DNR status and its legal validity to the family

A DNR order that has been reviewed and approved by the hospital ethics committee in accordance with Saudi MOH policy is a legally and ethically binding clinical directive. The wali's authority does not override a valid advance directive for a patient who, while alive, expressed a competent wish. Initiating resuscitation under family pressure contradicts the patient's documented wishes and violates the ethical principle of autonomy. The nurse's duty is to uphold the DNR, provide comfort care, and engage the physician to communicate with the family — involving the ethics committee if the dispute escalates.

Question 139: When performing nasopharyngeal suctioning, the nurse should apply suction:

Continuously throughout insertion and withdrawal
Only during insertion of the catheter
Only while withdrawing the catheter (Correct answer)
Before inserting the catheter

Correct answer: Only while withdrawing the catheter

Suction should only be applied while withdrawing the catheter to minimize mucosal trauma and hypoxia. Applying suction during insertion causes unnecessary tissue damage and depletes oxygen.

Question 140: In Saudi Arabia's MOH critical care units, a ventilated patient develops torsades de pointes (TdP) associated with prolonged QTc. The patient is currently on haloperidol, ondansetron, and ciprofloxacin. Which pharmacological intervention is MOST appropriate as first-line treatment for this arrhythmia?

Magnesium sulfate 2 g IV over 10–15 minutes (Correct answer)
Atropine 1 mg IV to increase heart rate
Amiodarone 300 mg IV bolus
Adenosine 6 mg IV rapid push

Correct answer: Magnesium sulfate 2 g IV over 10–15 minutes

Torsades de Pointes is a polymorphic ventricular tachycardia associated with prolonged QTc, often caused by QT-prolonging drugs (haloperidol, ondansetron, and fluoroquinolones like ciprofloxacin all prolong QT). First-line treatment is IV magnesium sulfate 1–2 g over 10–15 minutes, which suppresses early after-depolarizations even in normomagnesemic patients. Amiodarone itself prolongs QT and is CONTRAINDICATED in TdP. Adenosine is for supraventricular tachycardia. Atropine may be used for bradycardia-induced TdP, but is not the first-line pharmacological agent.

Question 141: The nurse is assessing a child for signs of increased intracranial pressure (ICP). Which finding is most specific to increased ICP in a 9-month-old infant?

Bulging anterior fontanelle (Correct answer)
Papilledema
Altered level of consciousness
Bradycardia and hypertension

Correct answer: Bulging anterior fontanelle

In infants with open fontanelles, bulging or tenseness of the anterior fontanelle is the most specific sign of increased ICP. In older children and adults where fontanelles are closed, papilledema and Cushing's triad are used.

Question 142: A patient is receiving a blood transfusion and develops fever, chills, and back pain 15 minutes after the transfusion begins. What is the priority nursing action?

Notify the blood bank before stopping the transfusion
Slow the transfusion rate and reassess in 30 minutes
Stop the transfusion immediately and maintain IV access with normal saline (Correct answer)
Administer antipyretics and continue the transfusion

Correct answer: Stop the transfusion immediately and maintain IV access with normal saline

These symptoms suggest an acute hemolytic transfusion reaction, a potentially fatal immune response. The priority is to stop the transfusion immediately while maintaining IV access with normal saline to prevent hemoglobin from precipitating in the renal tubules.

Question 143: A psychiatric nurse is evaluating two deteriorating patients. Patient A (on haloperidol) developed hyperthermia (40.2°C), 'lead-pipe' generalized rigidity, diaphoresis, and a markedly elevated CK over 48–72 hours. Patient B (on sertraline + tramadol started 6 hours ago) developed fever, agitation, diaphoresis, inducible clonus, and hyperreflexia within 2 hours of a dose change. Which feature BEST differentiates these two conditions?

The type of neuromuscular abnormality and onset timeline (Correct answer)
The degree of hyperthermia — NMS produces higher temperatures than serotonin syndrome
The CK elevation — serotonin syndrome produces higher CK values than NMS
The presence of diaphoresis — only serotonin syndrome causes autonomic instability

Correct answer: The type of neuromuscular abnormality and onset timeline

The most reliable differentiator between Neuroleptic Malignant Syndrome (NMS) and Serotonin Syndrome (SS) is the combination of neuromuscular findings and onset speed. NMS presents with 'lead-pipe' rigidity and hyporeflexia/bradyreflexia, developing over days. SS presents with clonus (especially inducible), hyperreflexia, and tremor, developing within hours of serotonergic agent initiation or dose change. Both can cause hyperthermia, diaphoresis, and autonomic instability. CK is markedly elevated in NMS due to rhabdomyolysis; it is usually normal or mildly elevated in SS.

Question 144: During Hajj season, a public health nurse is assigned to a medical station in Mina. A pilgrim is brought in with confusion, agitated behavior, absence of sweating, flushed dry skin, and a measured tympanic temperature of 41.2°C. A companion reports the patient had been walking outdoors for six hours in 44°C heat. Which nursing intervention takes HIGHEST priority?

Provide chilled oral rehydration fluid and place the patient in a shaded recovery position
Administer 1 g paracetamol suppository to reduce core temperature and monitor response for 15 minutes
Establish IV access and infuse 1 L of normal saline over 20 minutes to correct dehydration
Initiate rapid evaporative cooling — wet the skin and apply fans — while arranging immediate emergency transfer (Correct answer)

Correct answer: Initiate rapid evaporative cooling — wet the skin and apply fans — while arranging immediate emergency transfer

This presentation — hyperthermia above 40°C, anhidrosis (absence of sweating), and CNS dysfunction (confusion, agitation) — constitutes classic exertional heat stroke, a life-threatening emergency. Per Saudi MOH Hajj mass-gathering protocols, rapid core temperature reduction is the immediate priority. Evaporative cooling (misting with fans) is first-line in field settings. Oral fluids are contraindicated with altered consciousness. Paracetamol is ineffective in heat stroke as the hyperthermia is not cytokine-mediated. IV fluids are secondary to cooling and must not delay it.

Question 145: According to SCFHS nursing practice standards in Saudi Arabia, which of the following actions requires a nurse to document an incident report (تقرير الحوادث) in addition to the patient's medical record?

A patient refusing a scheduled medication after informed refusal counseling
Administering a medication 30 minutes late due to a delayed pharmacy delivery (Correct answer)
Applying a limb restraint following physician order for a confused patient
Discovering a patient's IV site is infiltrated and restarting the IV in a new location

Correct answer: Administering a medication 30 minutes late due to a delayed pharmacy delivery

A medication administered 30 minutes late constitutes a medication administration error or deviation from the prescribed schedule, which requires both documentation in the medical record and completion of a formal incident report per SCFHS and CBAHI patient safety standards. IV infiltration with site change, informed patient refusal, and ordered restraint application are expected nursing interventions that are documented in the medical record only and do not constitute adverse events requiring a separate incident report.

Question 146: A patient admitted with suspected Ebola hemorrhagic fever requires which level of transmission-based precautions?

Droplet precautions with surgical mask
Contact + Droplet + Airborne (full PPE including PAPR) (Correct answer)
Contact precautions with N95 mask
Standard precautions only

Correct answer: Contact + Droplet + Airborne (full PPE including PAPR)

Ebola requires all three levels of transmission-based precautions plus enhanced PPE including a powered air-purifying respirator (PAPR) or equivalent, due to high lethality, contact with body fluids, and potential aerosol generation during procedures. Saudi MOH and CDC recommend this approach.

Question 147: A community health nurse in Al-Qassim region — where Brucellosis is endemic — confirms a case of Brucella melitensis in a 40-year-old goat farmer following laboratory testing. The patient is referred for antibiotic treatment. What is the nurse's PRIMARY next action under Saudi MOH communicable disease control regulations?

Notify the Regional Health Affairs Directorate through the official reporting system and conduct a source investigation to identify the animal reservoir and raw dairy exposure (Correct answer)
Distribute prophylactic doxycycline to all household contacts and farm workers who handled animals
Quarantine all household members for 21 days and restrict movement from the property pending veterinary clearance
Arrange immediate pasteurization of all unpasteurized milk on the farm and report to the municipality only

Correct answer: Notify the Regional Health Affairs Directorate through the official reporting system and conduct a source investigation to identify the animal reservoir and raw dairy exposure

Brucellosis is a Category B notifiable disease in Saudi Arabia requiring mandatory reporting to the Regional Health Affairs Directorate. The community health nurse's primary public health role beyond clinical referral is official notification AND source investigation — identifying the animal reservoir (goats, camels, cattle), raw milk or unpasteurized cheese consumption, and occupational exposure routes. Household quarantine is not indicated; Brucellosis is not transmitted person-to-person. Prophylactic antibiotics are not routinely indicated for contacts without occupational exposure. Veterinary coordination through the Ministry of Environment, Water, and Agriculture is also triggered, but this is a secondary referral — the nurse's first duty is MOH notification and epidemiological investigation.

Question 148: The nurse is reviewing reportable diseases in Saudi Arabia. Tuberculosis, cholera, and measles are examples of which category?

Occupational diseases requiring employer notification
Non-communicable diseases with special reporting requirements
Diseases requiring treatment authorization only
Notifiable communicable diseases requiring mandatory reporting to MOH (Correct answer)

Correct answer: Notifiable communicable diseases requiring mandatory reporting to MOH

Saudi Arabia's MOH requires mandatory reporting of notifiable communicable diseases including TB, cholera, measles, meningitis, and others. Reporting enables surveillance, outbreak detection, and control measures. Non-compliance is a regulatory violation.

Question 149: A primigravida at 37 weeks presents with sudden onset severe headache, visual disturbances, and BP of 162/110 mmHg. The nurse should prepare for which condition?

Hypertensive urgency unrelated to pregnancy
Severe preeclampsia (Correct answer)
Gestational hypertension
Chronic hypertension exacerbation

Correct answer: Severe preeclampsia

Severe headache, visual disturbances, and BP ≥160/110 mmHg in a pregnant woman meet criteria for severe preeclampsia, requiring immediate antihypertensive and magnesium sulfate therapy.

Question 150: A nurse is caring for a patient with a Vancomycin-Resistant Enterococcus (VRE) infection. When should contact precautions be discontinued?

24 hours after the patient is discharged
After three consecutive negative cultures from relevant sites, per institutional policy (Correct answer)
After completing the full antibiotic course
When the patient is asymptomatic for 48 hours

Correct answer: After three consecutive negative cultures from relevant sites, per institutional policy

For VRE, contact precautions are typically continued until three consecutive negative cultures (stool/rectal swabs) are obtained from appropriate sites, at least one week apart, demonstrating decolonization. Institutional policy may specify additional criteria.

Question 151: A post-cardiac surgery patient in a Saudi tertiary hospital ICU develops sudden hypotension (BP 70/40 mmHg), elevated CVP of 22 mmHg, muffled heart sounds, and pulsus paradoxus of 18 mmHg. The 12-lead ECG shows electrical alternans. Which hemodynamic profile on pulmonary artery catheter would BEST confirm the diagnosis?

Low CVP with elevated cardiac output and low SVR
Equalization of RVEDP, LVEDP, and PAWP within 5 mmHg of each other (Correct answer)
Elevated PAP with normal PAWP and elevated PVR
Elevated PAWP with low cardiac output and high SVR

Correct answer: Equalization of RVEDP, LVEDP, and PAWP within 5 mmHg of each other

The clinical picture describes cardiac tamponade: Beck's triad (hypotension, elevated JVP/CVP, muffled heart sounds), pulsus paradoxus >10 mmHg, and electrical alternans on ECG. The pathognomonic PA catheter finding in tamponade is equalization of diastolic pressures — RVEDP, LVEDP, and PAWP all equilibrate within 5 mmHg of each other due to the constraining effect of pericardial fluid on all chambers. Option B describes cardiogenic shock. Option C describes distributive (septic) shock. Option D describes pulmonary hypertension.

Question 152: A school nurse notes an outbreak of head lice (pediculosis capitis) in an elementary school. Which public health measure is most evidence-based?

Treat affected children with pediculicide; no-nit policies are not recommended (Correct answer)
Fumigate the school
Screen all children daily for 4 weeks
Send all children home until all cases are treated

Correct answer: Treat affected children with pediculicide; no-nit policies are not recommended

Current evidence-based guidelines (CDC, AAP) recommend treating affected children with pediculicide shampoo and do NOT support 'no-nit' policies (sending children home for nit presence), as nits alone do not indicate active infestation and cause unnecessary school absence.

Question 153: A nurse is caring for a patient receiving total parenteral nutrition (TPN). Which complication should the nurse monitor for most closely?

Metabolic alkalosis
Hyperglycemia (Correct answer)
Hypokalemia
Dehydration

Correct answer: Hyperglycemia

Hyperglycemia is the most common complication of TPN because of the high dextrose concentration. Blood glucose should be monitored every 4–6 hours, and insulin may be required to maintain glucose within target range.

Question 154: A nurse in a Saudi hospital's neonatal unit must prepare dopamine for a 1.8 kg premature neonate. The order reads: dopamine 5 mcg/kg/min. Using the '6 × weight' rule (a common neonatal preparation formula), the nurse prepares dopamine 6 × 1.8 kg = 10.8 mg in 100 mL D10W. If the infusion runs at 5 mL/hr, what dose is the neonate actually receiving?

6.0 mcg/kg/min
2.5 mcg/kg/min
5.0 mcg/kg/min (Correct answer)
3.0 mcg/kg/min

Correct answer: 5.0 mcg/kg/min

Using the 6× rule: concentration = (6 × weight in kg) mg in 100 mL → 1 mL/hr = 1 mcg/kg/min. Therefore 5 mL/hr = 5 mcg/kg/min. Verification: concentration = 10.8 mg/100 mL = 0.108 mg/mL = 108 mcg/mL. Rate = 5 mL/hr ÷ 60 = 0.0833 mL/min. Dose = 108 × 0.0833 = 9 mcg/min ÷ 1.8 kg = 5 mcg/kg/min. The 6× rule is designed so that 1 mL/hr always equals 1 mcg/kg/min for dopamine, simplifying neonatal titration.

Question 155: A mechanically ventilated patient develops sudden hypotension, absent breath sounds on the left side, and tracheal deviation to the right. The nurse should first suspect:

Pleural effusion
Tension pneumothorax (Correct answer)
Hemothorax
Pulmonary embolism

Correct answer: Tension pneumothorax

Tension pneumothorax presents with tracheal deviation away from the affected side, unilateral absent breath sounds, and hemodynamic instability requiring immediate needle decompression.

Question 156: What is the normal fetal heart rate range during labor monitoring?

60-90 bpm
110-160 bpm (Correct answer)
80-100 bpm
160-200 bpm

Correct answer: 110-160 bpm

Normal fetal heart rate (FHR) during labor is 110-160 bpm. Tachycardia (>160) may indicate fever, infection, or fetal distress. Bradycardia (<110) may indicate cord compression or fetal hypoxia. Late decelerations suggest uteroplacental insufficiency.

Question 157: A patient is prescribed digoxin. Which assessment finding requires the nurse to withhold the medication and notify the physician?

Apical pulse of 52 beats per minute (Correct answer)
Serum sodium of 138 mEq/L
Blood pressure of 130/82 mmHg
Serum potassium of 3.8 mEq/L

Correct answer: Apical pulse of 52 beats per minute

Digoxin should be withheld if the apical pulse is below 60 beats per minute. Bradycardia is a sign of digoxin toxicity. Hypokalemia also increases digoxin toxicity risk, but the potassium level here is normal.

Question 158: Which of the following medications requires a peak and trough level to be drawn to monitor therapeutic efficacy and toxicity?

Amoxicillin
Doxycycline
Azithromycin
Gentamicin (Correct answer)

Correct answer: Gentamicin

Gentamicin (an aminoglycoside) has a narrow therapeutic index; peak levels assess efficacy and trough levels prevent nephrotoxicity and ototoxicity.

Question 159: Which mechanism explains why proton pump inhibitors (PPIs) are more effective than H2 blockers in treating GERD?

PPIs increase gastric motility
PPIs irreversibly block the final step of acid secretion (Correct answer)
PPIs stimulate mucus production
PPIs neutralize gastric acid directly

Correct answer: PPIs irreversibly block the final step of acid secretion

PPIs irreversibly inhibit the H+/K+-ATPase pump (the final common pathway), suppressing acid from all stimuli more completely than H2 blockers.

Question 160: The nurse is conducting contact tracing for a newly diagnosed patient with active tuberculosis. Which contacts are at highest priority for screening?

All students in the patient's school regardless of exposure time
Close contacts who shared air with the patient for cumulative >8 hours (Correct answer)
Casual contacts such as grocery store clerks
Online contacts and social media connections

Correct answer: Close contacts who shared air with the patient for cumulative >8 hours

TB contact tracing prioritizes close contacts based on the duration and proximity of exposure. The 'most infectious' contacts are those who shared enclosed air space for cumulative 8 or more hours (household members, close work colleagues). Concentric circle investigation expands outward if needed.

Question 161: In a patient with increased intracranial pressure (ICP), which nursing position is most appropriate?

Prone position
Trendelenburg position
Flat supine with no head elevation
Head of bed elevated 30–45 degrees with head midline (Correct answer)

Correct answer: Head of bed elevated 30–45 degrees with head midline

Elevating the head of bed 30–45 degrees with the head in midline promotes venous drainage and reduces ICP.

Question 162: A nurse is caring for a patient with severe burns covering 36% of total body surface area (TBSA). Using the Parkland formula, how much lactated Ringer's solution should be given in the first 8 hours?

One-quarter of the calculated 24-hour volume
The full 24-hour volume
One-third of the calculated 24-hour volume
Half of the calculated 24-hour volume (Correct answer)

Correct answer: Half of the calculated 24-hour volume

The Parkland formula is 4 mL × kg × % TBSA burned = total volume for 24 hours. Half is given in the first 8 hours (from time of injury), and the remaining half over the next 16 hours. This front-loading addresses the initial massive fluid shift.

Question 163: What patient education should be provided about NSAIDs like ibuprofen?

Take on an empty stomach for faster absorption
They can be used long-term without monitoring
Take with food to reduce GI irritation, avoid in renal disease, report black tarry stools, and avoid concurrent aspirin use (Correct answer)
NSAIDs have no side effects

Correct answer: Take with food to reduce GI irritation, avoid in renal disease, report black tarry stools, and avoid concurrent aspirin use

NSAID education: take with food (reduces GI ulceration risk), report GI bleeding signs (black stools), avoid in kidney disease (reduces renal blood flow), monitor blood pressure (can cause fluid retention), and avoid combining with other NSAIDs or anticoagulants.

Question 164: A critically ill patient in a Saudi ICU receiving total parenteral nutrition (TPN) develops a blood glucose of 14 mmol/L. According to Saudi SCCM-aligned protocols, what is the TARGET blood glucose range during TPN administration in ICU patients?

3.9–6.1 mmol/L (strict normoglycemia)
7.8–10 mmol/L (Correct answer)
11–14 mmol/L (permissive hyperglycemia)
4–7 mmol/L

Correct answer: 7.8–10 mmol/L

Current Saudi ICU and international critical care guidelines (SCCM/ESPEN) recommend a target blood glucose of 7.8–10 mmol/L for critically ill patients receiving TPN. Strict normoglycemia (3.9–6.1 mmol/L) was associated with higher hypoglycemia-related mortality in landmark NICE-SUGAR trials. Permissive hyperglycemia >10 mmol/L increases infection risk and impairs wound healing. The glucose reading of 14 mmol/L requires insulin intervention.

Question 165: A patient with traumatic brain injury is assessed and has a GCS score of 6. The nurse should interpret this score as indicating:

Severe brain injury requiring immediate airway management (Correct answer)
Vegetative state with no meaningful response
Moderate brain injury — patient responds to verbal stimuli only
Mild brain injury — patient is oriented and follows commands

Correct answer: Severe brain injury requiring immediate airway management

A GCS score of 8 or below indicates severe brain injury; these patients typically cannot protect their airway and require endotracheal intubation.

Question 166: A nurse in a tertiary hospital ICU notices that three healthcare workers developed similar febrile respiratory illness within 48 hours. Per Saudi MOH Infection Prevention and Control (IPC) Manual and mandatory notification requirements, within what timeframe must this potential healthcare-associated cluster be reported to the Regional Health Directorate?

Within 72 hours of identification
Within 48 hours of identification
Within 6 hours of identification
Within 24 hours of identification (Correct answer)

Correct answer: Within 24 hours of identification

The Saudi MOH IPC guidelines require mandatory notification of potential healthcare-associated outbreak clusters — including ≥2 linked cases among HCWs — to the Regional Health Directorate within 24 hours of identification. Waiting 48–72 hours delays public health response and violates MOH notification obligations. A 6-hour threshold applies to specific notifiable diseases (e.g., confirmed MERS-CoV), not cluster suspicion.

Question 167: A Saudi MOH community health nurse discovers that a Hajj season worker has active pulmonary tuberculosis confirmed by sputum smear positivity. The worker is currently asymptomatic for fever but has a productive cough. Under the Saudi MOH Hajj Health Regulations and the Communicable Disease Control Law, which statement BEST describes the nurse's legal obligations?

Initiate DOT and report to the facility infection control officer; external reporting is only required if transmission is confirmed
Report to Weqaya within 72 hours; the patient may continue duties with surgical mask use and directly observed therapy (DOT)
Report to the Hajj Ministry within 48 hours; isolation is voluntary unless the patient refuses treatment
Initiate immediate isolation, report to the local MOH Directorate and Weqaya within 24 hours, and the patient may not be permitted to continue Hajj duties until deemed non-infectious (Correct answer)

Correct answer: Initiate immediate isolation, report to the local MOH Directorate and Weqaya within 24 hours, and the patient may not be permitted to continue Hajj duties until deemed non-infectious

Saudi Arabia's Communicable Disease Prevention Law grants the MOH authority to mandate isolation for smear-positive TB, which is a notifiable disease requiring immediate action. During Hajj, where mass gathering amplifies transmission risk, Saudi MOH Hajj Health Regulations apply stricter controls: the worker must be immediately isolated, the case reported to both the local Directorate of Health Affairs and Weqaya within 24 hours, and the worker is prohibited from resuming public-facing Hajj duties until smear conversion (non-infectious status) is confirmed. Voluntary isolation or masking alone does not satisfy the legal standard for smear-positive cases in this high-risk context.

Question 168: A nurse in a Level III ICU accredited by CBAHI (Central Board for Accreditation of Healthcare Institutions) in Saudi Arabia is performing a daily spontaneous awakening trial (SAT) followed by a spontaneous breathing trial (SBT) on a post-ARDS patient. During the SBT on a T-piece at 30 minutes, the patient develops: RR 32 breaths/min, SpO₂ 91%, accessory muscle use, and a RSBI (Rapid Shallow Breathing Index) of 115 breaths/min/L. What is the MOST appropriate next step?

Proceed with extubation as the patient is demonstrating respiratory effort
Continue the SBT for the full 120-minute duration before making a decision
Terminate the SBT immediately and return the patient to pre-SBT ventilator settings (Correct answer)
Switch to pressure support ventilation at 10 cmH₂O and repeat RSBI after 60 minutes

Correct answer: Terminate the SBT immediately and return the patient to pre-SBT ventilator settings

The patient is demonstrating clear SBT failure criteria: RR >30 breaths/min, SpO₂ <92%, accessory muscle use, and RSBI >105 breaths/min/L (a threshold associated with SBT failure and extubation failure). Per CBAHI-endorsed ICU liberation protocols (aligned with ABCDEF bundle and ACCP/ATS guidelines), the SBT must be terminated immediately upon meeting failure criteria to prevent fatigue and hemodynamic compromise. The patient should be returned to comfortable, pre-SBT ventilator settings. Continuing for 120 minutes despite failure signs risks respiratory muscle fatigue. Extubation is contraindicated. Switching to PSV restarts rather than terminates the failed SBT and does not address immediate distress.

Question 169: A 52-year-old female patient is admitted to a Saudi hospital with suspected pulmonary embolism. She is on a therapeutic heparin infusion at 1,200 units/hour. Her most recent aPTT result is 210 seconds (therapeutic range: 60–100 seconds). The patient is now requesting to get up independently to use the bathroom. Concurrently, you note she has developed a petechial rash on both forearms. What is your priority nursing action?

Reduce the heparin rate by 200 units/hour per protocol and reassess aPTT in 6 hours
Assist the patient to the bathroom with a transfer belt, then notify the physician about the supratherapeutic aPTT
Hold the heparin infusion, keep the patient on strict bed rest, notify the physician immediately with the aPTT result and new rash findings (Correct answer)
Apply pressure stockings and allow supervised ambulation since mobility reduces DVT extension risk

Correct answer: Hold the heparin infusion, keep the patient on strict bed rest, notify the physician immediately with the aPTT result and new rash findings

An aPTT of 210 seconds is critically supratherapeutic (>3× the upper therapeutic limit), indicating severe anticoagulation with high bleeding risk. The petechial rash on the forearms suggests early bleeding manifestation, possibly early heparin-induced thrombocytopenia (HIT) or coagulopathy. Per SCFHS-aligned critical value protocols, a critically supratherapeutic aPTT is a medical emergency requiring immediate cessation of heparin, full bed rest to minimise trauma risk, and urgent physician notification. Ambulating this patient — even with assistance — risks a catastrophic intracranial haemorrhage or internal bleed. Adjusting the rate independently or delaying notification is a scope-of-practice violation in Saudi MOH facilities.

Question 170: A nurse working in a general medical ward in Riyadh is caring for a 68-year-old male patient with chronic kidney disease (CKD) Stage 4. The physician prescribes enemas until clear for bowel preparation before a diagnostic procedure. After the third enema, the patient becomes increasingly lethargic and his serum sodium returns at 128 mEq/L. Which physiological mechanism best explains this complication?

Absorption of hypotonic tap water through the colonic mucosa leading to dilutional hyponatraemia (Correct answer)
Suppression of aldosterone secretion due to bowel distension
Sodium loss through repeated stool evacuation causing true hyponatraemia
Stimulation of ADH release secondary to rectal pressure causing free water retention

Correct answer: Absorption of hypotonic tap water through the colonic mucosa leading to dilutional hyponatraemia

In CKD patients, the kidneys cannot excrete free water efficiently. Repeated tap water enemas result in absorption of hypotonic fluid across the colonic mucosa, expanding intravascular volume and diluting serum sodium — producing dilutional (hypotonic) hyponatraemia. This is particularly dangerous in CKD Stage 4 where GFR is 15–29 mL/min/1.73m². SCFHS guidelines emphasise caution with volume-expanding procedures in renally impaired patients. Sodium is not lost in significant quantities through stool, and aldosterone/ADH mechanisms described in the other options do not account for the primary pathophysiology here.

Question 171: The nurse is caring for a patient post-thyroidectomy. Which finding should the nurse assess for as the most serious immediate complication?

Mild hoarseness
Stridor and respiratory distress (Correct answer)
Hypokalemia
Facial flushing

Correct answer: Stridor and respiratory distress

Post-thyroidectomy, the most immediate life-threatening complication is hematoma formation causing airway compression, presenting as stridor and respiratory distress. Hypocalcemia (from parathyroid removal) and hoarseness are also concerns but are less immediately fatal.

Question 172: Which medication class is considered first-line treatment for generalized anxiety disorder (GAD) in outpatient settings?

Typical antipsychotics
Benzodiazepines
Selective serotonin reuptake inhibitors (SSRIs) (Correct answer)
Monoamine oxidase inhibitors (MAOIs)

Correct answer: Selective serotonin reuptake inhibitors (SSRIs)

SSRIs are first-line for GAD due to their efficacy and favorable safety profile without dependence risk.

Question 173: The nurse is administering IV calcium gluconate. What medication must be available at the bedside as an antidote?

Protamine sulfate
Flumazenil
Calcium EDTA
Sodium bicarbonate and cardiac monitoring equipment (Correct answer)

Correct answer: Sodium bicarbonate and cardiac monitoring equipment

Calcium gluconate is used to treat hypocalcemia and to protect the heart in hyperkalemia. However, rapid administration can cause bradycardia and cardiac arrest. ECG monitoring and resuscitation equipment (including sodium bicarbonate to manage arrhythmias) should be available.

Question 174: What are the nurse's legal responsibilities regarding documentation in Saudi healthcare?

Documentation is optional
Document accurately, timely, completely, using approved abbreviations, never alter records, and sign each entry (Correct answer)
Only document medications given
Documentation can be completed at the end of the shift

Correct answer: Document accurately, timely, completely, using approved abbreviations, never alter records, and sign each entry

Nursing documentation must be: accurate (factual), timely (as close to real-time as possible), complete (all assessments, interventions, outcomes), legible, using only approved abbreviations, never altered/deleted (late entries are acceptable with proper notation), and signed/authenticated.

Question 175: A nurse is preparing oral medications. The prescription reads: 'amoxicillin 750 mg PO. Available: 250 mg/5 mL suspension.' How many mL should be administered?

15 mL (Correct answer)
5 mL
10 mL
7.5 mL

Correct answer: 15 mL

Volume = (desired dose / available dose) × volume = (750 mg / 250 mg) × 5 mL = 3 × 5 = 15 mL. This is a standard oral liquid calculation.

Question 176: A patient with heart failure is prescribed furosemide. Which electrolyte level requires monitoring?

Magnesium
Calcium
Potassium (Correct answer)
Sodium

Correct answer: Potassium

Furosemide (a loop diuretic) causes potassium wasting through increased urinary excretion. Hypokalemia is the most significant electrolyte imbalance, increasing the risk of dangerous arrhythmias and digoxin toxicity if the patient is also on digoxin.

Question 177: A nurse is preparing to administer a medication. Which of the 'rights' of medication administration is verified by checking the patient's ID band?

Right dose
Right medication
Right patient (Correct answer)
Right route

Correct answer: Right patient

Checking the patient's ID band verifies the right patient, one of the 10 rights of medication administration. At least two patient identifiers should be used before administering any medication.

Question 178: Per the Saudi MOH IPC Manual aligned with CBAHI Patient Safety Standards, a sharps container in a clinical area should be sealed and sent for disposal when it reaches which fill level?

One-half (50%) full
Three-quarters (75%) full (Correct answer)
Two-thirds (67%) full
Completely full (100%)

Correct answer: Three-quarters (75%) full

Saudi MOH IPC guidelines and CBAHI standards specify that sharps containers must be sealed and removed from clinical areas when they reach three-quarters (75%) full. Filling beyond this level significantly increases the risk of needlestick injury during closure. Allowing containers to reach 100% capacity violates both MOH healthcare waste regulations and CBAHI accreditation standards, and can result in a non-conformity finding during audit.

Question 179: Which disinfectant level is required for semi-critical medical devices (devices that contact intact mucous membranes)?

High-level disinfection (e.g., glutaraldehyde, hydrogen peroxide, OPA) (Correct answer)
Sterilization
Intermediate-level disinfection with alcohol
Low-level disinfection

Correct answer: High-level disinfection (e.g., glutaraldehyde, hydrogen peroxide, OPA)

The Spaulding classification requires high-level disinfection for semi-critical items (contact with intact mucous membranes, e.g., endoscopes, respiratory therapy equipment). High-level disinfection kills all microorganisms except large numbers of bacterial spores. Critical items (enter sterile tissue) require sterilization.

Question 180: Which blood pressure reading would be classified as hypertension stage 1 according to current guidelines?

≥140/≥90 mmHg
120–129/<80 mmHg
130–139/80–89 mmHg (Correct answer)
<120/<80 mmHg

Correct answer: 130–139/80–89 mmHg

According to updated cardiovascular guidelines, hypertension stage 1 is defined as systolic 130–139 mmHg or diastolic 80–89 mmHg. Elevated blood pressure is 120–129/<80, and stage 2 hypertension is ≥140/≥90.

Question 181: A 4-month-old infant is brought to a Saudi PHC center for her first visit. Records show she missed all 2-month vaccinations. The mother reports the infant had a fever of 38.3°C three days ago that has since completely resolved, and the baby appears well today. According to Saudi MOH Expanded Programme on Immunization (EPI) guidelines, what is the CORRECT action?

Administer only the oral vaccines today and schedule the injectable vaccines for next week to limit injection-site reactions
Administer all overdue vaccines today, as a recent mild febrile illness that has resolved is not a contraindication under Saudi EPI catch-up guidelines (Correct answer)
Postpone all vaccines for four weeks to ensure full recovery from the febrile illness
Administer the pentavalent and PCV vaccines today but defer BCG, since BCG requires a minimum four-week illness-free interval

Correct answer: Administer all overdue vaccines today, as a recent mild febrile illness that has resolved is not a contraindication under Saudi EPI catch-up guidelines

Saudi MOH EPI catch-up guidelines, aligned with WHO EPI principles, specify that mild illness — including low-grade fever — that has resolved does not contraindicate vaccination. Delaying vaccination in recovered infants increases the window of susceptibility to vaccine-preventable diseases. All overdue vaccines (Penta, IPV/OPV, PCV, Rota, BCG if missed at birth) should be administered at the same visit per the Saudi catch-up schedule. The 4-week deferral rule applies to live vaccines given after another live vaccine, not after a febrile illness.

Question 182: A 28-year-old primigravida at 34 weeks gestation presents to a Saudi hospital with a blood pressure of 152/98 mmHg, proteinuria of 2+ on dipstick, and complaints of epigastric pain and visual disturbances. Her platelet count is 88,000/µL and AST is 112 U/L. According to Saudi SCFHS guidelines, which condition best describes this clinical picture and what is the PRIORITY nursing intervention?

Chronic hypertension superimposed on pregnancy; increase methyldopa dose and monitor fetal movement
Gestational hypertension; initiate oral antihypertensive therapy and schedule follow-up in 48 hours
Severe preeclampsia with HELLP syndrome; administer magnesium sulfate IV and prepare for urgent delivery (Correct answer)
Mild preeclampsia; restrict activity, encourage left lateral positioning, and monitor BP every 4 hours

Correct answer: Severe preeclampsia with HELLP syndrome; administer magnesium sulfate IV and prepare for urgent delivery

This presentation meets criteria for severe preeclampsia with HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets): BP ≥150/100, thrombocytopenia <100,000/µL, elevated AST, epigastric pain (hepatic involvement), and visual disturbances. Per SCFHS and Saudi MOH perinatal guidelines, the priority interventions are seizure prophylaxis with IV magnesium sulfate and preparation for urgent delivery, as HELLP syndrome is life-threatening to both mother and fetus regardless of gestational age.

Question 183: A nurse in a Saudi MOH hospital is preparing to perform a sterile dressing change. While opening the sterile field, the outer edge of the sterile drape falls below the level of the trolley surface. Which principle of surgical asepsis has been violated, and what is the correct action?

The line-of-sight rule is violated; reposition the drape without touching the sterile field
The 2.5 cm border rule is violated; discard and open a new drape because the dependent edge is considered contaminated (Correct answer)
No principle is violated; items hanging below the trolley remain sterile if untouched
The time-exposure rule is violated; proceed quickly and complete the dressing within 3 minutes

Correct answer: The 2.5 cm border rule is violated; discard and open a new drape because the dependent edge is considered contaminated

In surgical asepsis, any part of the sterile drape that falls below the level of the sterile field (or below the trolley surface) is considered contaminated. The 2.5 cm (1-inch) border around the edge of a sterile field is also considered non-sterile. Since the drape has been compromised, the entire setup must be discarded and a new sterile field established. The principle violated is that 'sterile objects become contaminated if they fall below the waist or table level.'

Question 184: What are the common side effects of antipsychotic medications that nurses should monitor?

Improved mood only
No side effects occur with modern medications
Extrapyramidal symptoms (dystonia, akathisia, tardive dyskinesia), sedation, weight gain, and metabolic syndrome (Correct answer)
Only headache

Correct answer: Extrapyramidal symptoms (dystonia, akathisia, tardive dyskinesia), sedation, weight gain, and metabolic syndrome

Antipsychotic side effects include: EPS (muscle stiffness, tremors, restlessness, involuntary movements), sedation, significant weight gain, metabolic syndrome (diabetes risk), orthostatic hypotension, and rare but dangerous neuroleptic malignant syndrome (NMS).

Question 185: A patient on lithium carbonate for bipolar I disorder presents to a Saudi psychiatric unit with coarse tremors, ataxia, slurred speech, and worsening confusion. His serum lithium level is 2.3 mEq/L. Which intervention is the PRIORITY?

Proceed directly to hemodialysis given the symptomatic presentation
Reduce the lithium dose by half and recheck the serum level in 24 hours
Discontinue lithium immediately and initiate IV isotonic saline hydration (Correct answer)
Administer sodium bicarbonate IV to alkalinize the urine and enhance excretion

Correct answer: Discontinue lithium immediately and initiate IV isotonic saline hydration

A serum lithium level of 2.3 mEq/L represents moderate toxicity (2.0–2.5 mEq/L), manifesting as CNS symptoms (ataxia, confusion) and neuromuscular signs. The priority is stopping lithium and restoring sodium balance with IV normal saline, as sodium competes with lithium for renal reabsorption, promoting lithium excretion. Hemodialysis is reserved for severe toxicity (levels >3.5 mEq/L, or severe/refractory symptoms). Reducing the dose is inadequate for moderate toxicity. Sodium bicarbonate is not a standard intervention for lithium toxicity.

Question 186: Which antiseptic agent is recommended for skin antisepsis before central line insertion according to Saudi MOH/CDC guidelines?

Normal saline with chlorhexidine
Isopropyl alcohol 70% alone
Chlorhexidine gluconate 2% in 70% isopropyl alcohol (Correct answer)
Povidone-iodine 10%

Correct answer: Chlorhexidine gluconate 2% in 70% isopropyl alcohol

Current guidelines (CDC, Saudi MOH IPC) recommend chlorhexidine gluconate 2% in 70% isopropyl alcohol for central line insertion site antisepsis. It provides both rapid (alcohol) and sustained (chlorhexidine) antimicrobial activity, reducing CLABSI more effectively than povidone-iodine alone.

Question 187: A patient in a Saudi hospital is found to have carbapenem-resistant Klebsiella pneumoniae (CRKP). What action beyond contact precautions should be taken?

Treat empirically with vancomycin
Standard contact precautions only — no additional action needed
Active surveillance cultures of contacts, cohorting, and notification to IPC team for outbreak investigation (Correct answer)
Discharge the patient to home isolation

Correct answer: Active surveillance cultures of contacts, cohorting, and notification to IPC team for outbreak investigation

Carbapenem-resistant organisms (CROs) represent a major threat and require enhanced measures beyond standard contact precautions: active surveillance cultures of roommates/contacts, cohorting of positive patients, notification of IPC team for investigation, and review of antibiotic stewardship.

Question 188: A patient's Glasgow Coma Scale score is 8. How should the nurse interpret this finding?

Severe brain injury requiring immediate intervention (Correct answer)
Mild confusion with intact orientation
Moderate injury with expected full recovery
Normal neurological status

Correct answer: Severe brain injury requiring immediate intervention

The Glasgow Coma Scale ranges from 3 (deep coma/brain death) to 15 (fully alert). A score of 8 or below indicates severe brain injury and typically necessitates airway management and urgent medical intervention.

Question 189: A Saudi primigravida undergoes a scheduled repeat cesarean section at 38 weeks. Thirty minutes postoperatively, her uterus is boggy, and estimated blood loss is 1,200 mL despite oxytocin infusion. She is hemodynamically stable (BP 100/70, HR 105). Per MOH hemorrhage protocols, after bimanual uterine massage and a second uterotonic agent (ergometrine), bleeding continues. What is the CORRECT next pharmacological step?

Carboprost (15-methyl PGF2α) 0.25 mg IM, may repeat every 15–90 minutes up to 8 doses (Correct answer)
Tranexamic acid 1 g IV over 10 minutes
IV oxytocin 80 units bolus
Misoprostol 800 mcg sublingual as sole additional agent

Correct answer: Carboprost (15-methyl PGF2α) 0.25 mg IM, may repeat every 15–90 minutes up to 8 doses

When oxytocin and ergometrine fail, the stepwise MOH/WHO postpartum hemorrhage algorithm calls for carboprost (PGF2α analogue) 0.25 mg IM as the third-line uterotonic. It is repeated every 15–90 min up to 8 doses. Tranexamic acid is an adjunct antifibrinolytic given early in PPH (within 3 hours) but does not replace uterotonics. An 80-unit oxytocin bolus risks severe cardiovascular adverse effects. Misoprostol alone is not preferred when superior agents are available.

Question 190: What is the PRIMARY purpose of conducting a root cause analysis (RCA) after a sentinel event?

To identify system-level factors and prevent recurrence (Correct answer)
To document the sequence of events for the medical record
To identify and discipline the staff member responsible
To satisfy mandatory legal reporting requirements

Correct answer: To identify system-level factors and prevent recurrence

RCA focuses on underlying system failures rather than individual blame, aiming to implement systemic changes that prevent recurrence.

Question 191: A nurse is performing wound care for a patient with a Stage III pressure injury over the sacrum. The wound bed shows 70% yellow slough and 30% granulation tissue. There is no clinical sign of infection. The physician orders wet-to-dry dressing changes three times daily. Based on current evidence-based wound care principles aligned with Saudi SCFHS competency standards, what should the nurse do?

Apply wet-to-dry dressings but soak the gauze in povidone-iodine to reduce biofilm formation
Perform sharp debridement at the bedside before applying the wet-to-dry dressing to accelerate healing
Clarify the order with the physician and advocate for moist wound healing dressings such as hydrocolloid or foam, as wet-to-dry dressings are non-selective and damage granulation tissue (Correct answer)
Proceed with wet-to-dry dressings as ordered because mechanical debridement is the gold standard for slough removal in Stage III injuries

Correct answer: Clarify the order with the physician and advocate for moist wound healing dressings such as hydrocolloid or foam, as wet-to-dry dressings are non-selective and damage granulation tissue

Evidence-based practice — endorsed by SCFHS and aligned with international wound care guidelines adopted in Saudi MOH facilities — indicates that wet-to-dry dressings are non-selective debridement methods that remove viable granulation tissue along with slough, causing pain and impairing healing. For Stage III pressure injuries with slough, moist wound healing using autolytic debridement agents (hydrocolloid, foam, or alginate dressings) is preferred. The nurse has both a professional and ethical obligation under SCFHS Code of Ethics to advocate for evidence-based care and clarify orders that may cause patient harm. Povidone-iodine is cytotoxic to granulation tissue; bedside sharp debridement requires specific credentialing beyond standard nursing scope.

Question 192: When teaching a patient with limited health literacy, the nurse should:

Use plain language and teach-back method (Correct answer)
Use medical terminology for accuracy
Limit teaching to one session
Provide detailed written pamphlets

Correct answer: Use plain language and teach-back method

The teach-back method (asking patients to repeat information in their own words) is the most effective strategy for verifying understanding, especially with patients with limited health literacy. Plain language removes barriers.

Question 193: A patient is prescribed warfarin. Which medication interaction significantly increases the risk of bleeding?

Omeprazole
Cholestyramine
Aspirin and NSAIDs (Correct answer)
Vitamin K supplements

Correct answer: Aspirin and NSAIDs

Aspirin and NSAIDs inhibit platelet aggregation and can also inhibit warfarin metabolism, significantly increasing anticoagulant effect and bleeding risk. The combination of warfarin anticoagulation plus antiplatelet effect is particularly dangerous for GI bleeding.

Question 194: A nurse in a Saudi NICU is caring for a 28-week preterm neonate receiving nasal CPAP at FiO₂ 0.35. Arterial blood gas shows: pH 7.22, PaCO₂ 62 mmHg, PaO₂ 54 mmHg, HCO₃ 24 mEq/L, SaO₂ 86%. The neonatologist suspects surfactant deficiency. Before surfactant administration via the INSURE technique (Intubate–Surfactant–Extubate), which nursing assessment finding would indicate that the neonate is NOT an appropriate INSURE candidate at this moment?

Blood pressure of 38/20 mmHg (MAP 26 mmHg) requiring ongoing dopamine infusion at 10 mcg/kg/min (Correct answer)
Temperature of 36.6°C maintained in an open incubator with radiant heat
Presence of grade II intraventricular hemorrhage (IVH) on the most recent cranial ultrasound
Heart rate of 148 bpm with occasional bradycardic episodes dropping to 100 bpm during nasal suctioning

Correct answer: Blood pressure of 38/20 mmHg (MAP 26 mmHg) requiring ongoing dopamine infusion at 10 mcg/kg/min

The INSURE technique involves brief intubation for surfactant delivery, which requires hemodynamic stability. Hemodynamic instability — specifically cardiovascular compromise requiring vasoactive support (dopamine infusion) with a MAP of 26 mmHg in a 28-weeker (normal MAP ≥ gestational age in weeks, i.e., ≥28 mmHg) — is a contraindication to elective intubation for INSURE, as the procedure carries risk of further cardiovascular deterioration. Grade II IVH is not a contraindication to INSURE. Mild bradycardia during suctioning is common and not disqualifying. A temperature of 36.6°C is within acceptable range. Cardiovascular stabilization must precede elective intubation in the INSURE protocol.

Question 195: A nurse in a SCFHS-accredited facility is caring for a patient with chronic kidney disease (CKD) Stage 4 who is prescribed sodium polystyrene sulfonate (Kayexalate) for hyperkalemia. The patient has had no bowel movement for 3 days. What is the most critical assessment finding that should prompt the nurse to withhold this medication and notify the physician immediately?

Blood pressure of 148/92 mmHg with mild peripheral edema
Abdominal distension with absent bowel sounds and the patient reporting nausea (Correct answer)
Serum potassium of 5.8 mEq/L with peaked T-waves on ECG
Serum sodium of 138 mEq/L and serum bicarbonate of 18 mEq/L

Correct answer: Abdominal distension with absent bowel sounds and the patient reporting nausea

Sodium polystyrene sulfonate is contraindicated in patients with reduced or absent intestinal motility (ileus or bowel obstruction) because it can cause intestinal necrosis, a rare but life-threatening complication. Abdominal distension with absent bowel sounds and nausea in a patient who has not had a bowel movement for 3 days indicates possible ileus — an absolute contraindication. Hyperkalemia with ECG changes (option A) is the reason TO give Kayexalate, not withhold it. Options C and D are expected findings in CKD that do not contraindicate the medication.

Question 196: What is informed consent and what are the nurse's responsibilities?

The nurse ensures the patient understands the procedure, witnesses the consent signature, and documents the process — the physician explains risks/benefits (Correct answer)
Verbal consent is always sufficient
The nurse obtains consent for surgery
Consent is optional in emergencies

Correct answer: The nurse ensures the patient understands the procedure, witnesses the consent signature, and documents the process — the physician explains risks/benefits

Informed consent is the physician's responsibility to explain (procedure, risks, benefits, alternatives). The nurse's role: ensure patient understanding, witness the signature, verify the patient is competent and not coerced, and document. In Saudi Arabia, consent follows Islamic ethics and MOH guidelines.

Question 197: A child weighing 15 kg requires IV fluid resuscitation. The Holliday-Segar formula for maintenance fluids for this child gives:

1,000 mL/day
1,250 mL/day (Correct answer)
750 mL/day
1,500 mL/day

Correct answer: 1,250 mL/day

Holliday-Segar: 100 mL/kg for first 10 kg + 50 mL/kg for 10–20 kg + 20 mL/kg above 20 kg. For 15 kg: (10 × 100) + (5 × 50) = 1,000 + 250 = 1,250 mL/day.

Question 198: A patient develops hypotension, tachycardia, warm flushed skin, and a widened pulse pressure following a severe anaphylactic reaction. This presentation is most characteristic of:

Distributive shock (Correct answer)
Obstructive shock
Hypovolemic shock
Cardiogenic shock

Correct answer: Distributive shock

Distributive shock, as seen in anaphylaxis, is caused by massive vasodilation leading to a relative hypovolemia with warm skin and widened pulse pressure.

Question 199: A patient in the hospital develops diarrhea and is positive for Clostridioides difficile (C. diff). Which type of gloves should the nurse wear?

Standard exam gloves; alcohol hand rub is sufficient
Non-sterile gloves — but alcohol-based hand rub is NOT sufficient; soap and water required (Correct answer)
Sterile gloves with double-gloving
No gloves if using alcohol hand rub

Correct answer: Non-sterile gloves — but alcohol-based hand rub is NOT sufficient; soap and water required

C. difficile spores are not killed by alcohol-based hand sanitizers. Soap and water must be used for hand hygiene when caring for C. diff patients, as the physical scrubbing action removes spores. Contact precautions (gloves and gown) are required.

Question 200: A nurse in a Saudi MOH hospital discovers that a senior physician has been repeatedly performing a procedure without obtaining informed consent, citing patient family approval as sufficient. Under the Saudi Patient Rights Charter (1436H) and SCFHS ethical standards, what is the nurse's MOST appropriate course of action?

Confront the physician publicly during rounds to protect future patients
Report directly to the Saudi Commission for Health Specialties without first using internal channels
Document the pattern and escalate through the hospital's Patient Rights Committee or formal incident reporting system (Correct answer)
Accept the family-consent model as culturally appropriate in the Saudi context and continue assisting

Correct answer: Document the pattern and escalate through the hospital's Patient Rights Committee or formal incident reporting system

The Saudi Patient Rights Charter mandates individual informed consent from competent adult patients; family consent alone does not substitute unless the patient lacks capacity. The nurse is ethically and professionally obligated to document the pattern and escalate through established internal channels — the Patient Rights Committee or incident reporting system — before external escalation. Skipping internal channels (option D) violates institutional protocol, while accepting the practice (option A) violates the charter, and public confrontation (option C) is unprofessional and counterproductive.
