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

Question 1: The nurse is caring for a patient after a right-sided stroke. Where should the nurse expect motor deficits?

Left side of the body (Correct answer)
Face only
Both sides equally
Right side of the body

Correct answer: Left side of the body

The brain controls the contralateral (opposite) side of the body due to decussation of motor fibers in the medulla. A right-sided stroke causes left-sided (contralateral) hemiplegia or hemiparesis.

Question 2: What is the antidote for acetaminophen (paracetamol) overdose?

Protamine sulfate
Activated charcoal only
Naloxone
N-acetylcysteine (NAC/Mucomyst) (Correct answer)

Correct answer: N-acetylcysteine (NAC/Mucomyst)

N-acetylcysteine (NAC) is the antidote for acetaminophen overdose. It works by replenishing glutathione stores in the liver, which are depleted during acetaminophen metabolism. It is most effective when given within 8-10 hours of overdose.

Question 3: A psychiatric nurse has been assigned to a male patient admitted for major depressive disorder. Over several weeks, she notices she becomes distressed when he misses sessions, brings him personal items 'to cheer him up,' stays late on her shifts specifically to be available to him, and realizes he resembles her younger brother who died by suicide. This clinical phenomenon is BEST described as:

Transference — the patient is projecting his unresolved feelings onto the nurse
Therapeutic use of self — the nurse is appropriately leveraging personal experience to build rapport
Professional boundary violation only, with no underlying psychological mechanism
Countertransference — the nurse is experiencing an unconscious emotional response rooted in her own personal history (Correct answer)

Correct answer: Countertransference — the nurse is experiencing an unconscious emotional response rooted in her own personal history

Countertransference refers to the nurse's (or clinician's) unconscious emotional reactions toward a patient, driven by the nurse's own unresolved conflicts, experiences, or needs — in this case, her unresolved grief over her brother's suicide. It differs from transference (which is the patient projecting feelings onto the clinician). While the behaviors described also constitute boundary violations, the root mechanism is countertransference. Recognizing it is essential; the nurse must bring this to clinical supervision immediately. Unexamined countertransference can severely compromise therapeutic integrity and patient safety, particularly with suicidal patients.

Question 4: Which of the following BEST describes the 'chain of survival' concept in patient safety?

The process of transferring critically ill patients safely
A documentation system for adverse events
A hierarchy of nursing responsibilities during a code
A series of linked actions that increase survival from cardiac arrest (Correct answer)

Correct answer: A series of linked actions that increase survival from cardiac arrest

The chain of survival includes early recognition, CPR, defibrillation, and post-resuscitation care — each link improves cardiac arrest outcomes.

Question 5: A nurse is documenting patient care. Which entry is most appropriate?

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.
Left knee pain treated per standard protocol.
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 6: What is the correct sequence of steps in the nursing process?

Assessment, Planning, Diagnosis, Implementation, Evaluation
Planning, Assessment, Diagnosis, Implementation, Evaluation
Diagnosis, Assessment, Planning, Evaluation, Implementation
Assessment, Diagnosis, Planning, Implementation, Evaluation (Correct answer)

Correct answer: Assessment, Diagnosis, Planning, Implementation, Evaluation

The nursing process follows ADPIE: Assessment (collecting data), Diagnosis (identifying problems), Planning (setting goals), Implementation (carrying out interventions), and Evaluation (assessing outcomes).

Question 7: A patient is taking St. John's Wort with their antiretroviral therapy. What is the most significant drug interaction concern?

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

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 8: The nurse is performing hand hygiene. What is the minimum recommended duration for rubbing hands with alcohol-based hand rub?

20–30 seconds (Correct answer)
60 seconds
15 seconds
5–10 seconds

Correct answer: 20–30 seconds

WHO guidelines recommend rubbing hands with alcohol-based hand rub for 20–30 seconds, covering all surfaces, until hands are dry. This duration ensures effective reduction of microbial load.

Question 9: The nurse is cleaning and disinfecting a blood spill on the floor. What is the correct sequence?

Clean with water first, then apply bleach, then remove residue
Remove blood with bare hands first, then apply alcohol hand rub
Put on PPE, remove gross contamination with absorbent material, then disinfect with appropriate agent (e.g., 0.5% sodium hypochlorite) (Correct answer)
Apply disinfectant first, then remove the blood

Correct answer: Put on PPE, remove gross contamination with absorbent material, then disinfect with appropriate agent (e.g., 0.5% sodium hypochlorite)

Blood spill management: PPE first (protect self), then remove gross soiling using paper towels/absorbent material (never bare hands), then apply approved disinfectant (0.5% sodium hypochlorite/bleach), allow contact time, and dispose of waste as clinical waste.

Question 10: According to Saudi MOH Circular No. 9/B/4908 on healthcare-associated infections (HAIs), which organism has a mandated contact isolation threshold of a single positive culture result, regardless of clinical signs, in Saudi Arabian acute-care facilities?

Extended-spectrum beta-lactamase (ESBL)-producing organisms
Vancomycin-resistant Enterococcus (VRE)
Carbapenem-resistant Enterobacteriaceae (CRE) (Correct answer)
Methicillin-resistant Staphylococcus aureus (MRSA)

Correct answer: Carbapenem-resistant Enterobacteriaceae (CRE)

Saudi MOH mandates immediate contact precautions upon a single positive culture for CRE due to its extremely limited treatment options and high mortality rate in Saudi hospitals. Unlike MRSA or VRE, which may require confirmatory cultures or clinical correlation in some protocols, CRE triggers automatic isolation at first detection per Saudi infection prevention and control (IPC) national guidelines.

Question 11: An elderly Saudi woman is admitted after a fall at home. Assessment reveals she takes multiple medications including a calcium channel blocker, a diuretic, and a sleeping tablet. Which factor from her medication list MOST contributes to fall risk?

The sleeping tablet (sedative/hypnotic) (Correct answer)
The diuretic alone
Taking three medications simultaneously
The calcium channel blocker alone

Correct answer: The sleeping tablet (sedative/hypnotic)

Sedative and hypnotic medications are classified as high-risk 'Beers Criteria' drugs for elderly patients because they cause excessive sedation, impaired balance, and psychomotor slowing — all direct fall risk factors. While calcium channel blockers may cause orthostatic hypotension and diuretics may cause dehydration/electrolyte imbalance, the sedative is the single greatest fall risk in this scenario. Polypharmacy in general also increases risk, but the question asks for the single MOST contributing factor.

Question 12: 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?

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

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 13: Which action by a nurse BEST demonstrates the ethical principle of justice in patient care?

Spending extra time with patients who are most cooperative
Prioritizing patients who have private insurance
Allocating care based on severity of need regardless of social status (Correct answer)
Giving preferential treatment to patients referred by senior physicians

Correct answer: Allocating care based on severity of need regardless of social status

Justice requires fair distribution of care based on clinical need, not social or financial factors.

Question 14: A nurse in a Saudi Ministry of Health hospital is preparing to perform a sterile dressing change on a patient with a stage III pressure injury. During the procedure, the nurse's sterile glove accidentally touches the outer edge of the sterile field border (2 cm from the edge). What is the most appropriate action?

Continue the procedure, as only the center of the sterile field is considered contaminated
Continue the procedure only if the contact was brief and light
Wipe the glove with an alcohol swab and continue the procedure
Consider the glove contaminated and replace it before continuing (Correct answer)

Correct answer: Consider the glove contaminated and replace it before continuing

In sterile technique, a 2.5 cm (1-inch) border around the edges of a sterile field is considered contaminated. Since the glove touched within this border zone, it is considered contaminated regardless of how briefly or lightly contact occurred. The nurse must replace the glove immediately before continuing. Wiping with alcohol does not restore sterility, and there is no 'brief contact' exception in aseptic technique principles.

Question 15: A CBAHI accreditation surveyor audits the hand hygiene program of a Saudi MOH-accredited hospital. The surveyor reviews the facility's direct observation compliance data for the past quarter. What is the MINIMUM acceptable hand hygiene compliance rate required by CBAHI Patient Safety Standards to avoid a non-conformity finding?

60%
80% (Correct answer)
90%
70%

Correct answer: 80%

CBAHI Patient Safety Standards set a minimum hand hygiene compliance threshold of 80% based on direct observation audits covering all five WHO moments. Facilities falling below this benchmark receive a non-conformity finding, which must be addressed through a corrective action plan. A 70% rate — while commonly cited as a baseline in older literature — falls below current CBAHI requirements. The 90% threshold is an aspirational goal recommended by MOH IPC leadership but is not the minimum standard required to pass accreditation.

Question 16: The nurse discovers that a patient who died in the ICU tested positive for Creutzfeldt-Jakob disease (CJD). Which decontamination method is required for instruments used on this patient?

Extended autoclave at 134°C for 18 minutes (porous load) — standard disinfection is ineffective (Correct answer)
Hydrogen peroxide gas plasma sterilization
Standard steam autoclave at 121°C for 15 minutes
Glutaraldehyde immersion for 30 minutes

Correct answer: Extended autoclave at 134°C for 18 minutes (porous load) — standard disinfection is ineffective

Prions (CJD causative agents) are extremely resistant to standard sterilization. The WHO recommends extended steam autoclaving (134°C, 18 min) in a porous load autoclave, combined with sodium hydroxide pre-treatment. Standard disinfectants do not inactivate prions.

Question 17: A malnourished patient receiving total parenteral nutrition (TPN) develops confusion, muscle cramps, and a phosphate level of 0.4 mmol/L. The nurse recognizes this as:

Refeeding syndrome (Correct answer)
Hyperosmolar hyperglycemic state
Hyperglycemia
Hypercalcemia

Correct answer: Refeeding syndrome

Refeeding syndrome occurs in malnourished patients receiving aggressive nutrition support and is characterized by severe hypophosphatemia, causing neurological and muscular complications.

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

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

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 20: 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?

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

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 21: A 67-year-old male patient with type 2 diabetes is admitted to a Saudi hospital with a serum glucose of 38 mmol/L (684 mg/dL), serum osmolarity of 342 mOsm/kg, pH 7.38, HCO₃ 24 mEq/L, and no ketonemia. He is confused and oliguric. His admission weight is 74 kg. Which nursing intervention requires the most careful monitoring in the first 4 hours?

Insulin drip titration to reduce serum glucose by no more than 4–5 mmol/L per hour
IV fluid resuscitation rate and neurological status to detect cerebral edema from rapid osmolarity correction (Correct answer)
Potassium replacement to prevent hypokalemia before insulin therapy is initiated
Cardiac monitoring for hyperkalemia-related dysrhythmias during the acute phase

Correct answer: IV fluid resuscitation rate and neurological status to detect cerebral edema from rapid osmolarity correction

This presentation is Hyperosmolar Hyperglycemic State (HHS), not DKA — evidenced by markedly elevated glucose and osmolarity without acidosis or ketonemia. The primary danger in HHS management is overly rapid reduction of serum osmolarity through aggressive fluid resuscitation, which can cause fluid to shift rapidly into brain cells, precipitating fatal cerebral edema. Osmolarity should be reduced by no more than 3–4 mOsm/kg/hour. Neurological monitoring (GCS, pupil response) is the most critical nursing parameter in the first 4 hours. While potassium monitoring is important in DKA before insulin, HHS patients are more commonly volume-depleted, and the primary risk is the rate of osmolarity correction.

Question 22: 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?

Delete the original entry and re-enter the correct pain score with the original timestamp to maintain chronological accuracy
Overwrite the original entry with the correct value since electronic systems automatically log the change
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)
Leave the original entry unchanged and write a separate incident report only, without amending the EHR

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

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

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 24: Which of the following is a subjective finding during patient assessment?

Temperature of 38.5°C
Patient reports pain of 8/10 (Correct answer)
Respiratory rate of 22 breaths per minute
Blood pressure of 150/90 mmHg

Correct answer: Patient reports pain of 8/10

Subjective data is information reported by the patient that cannot be directly measured, such as pain, nausea, or dizziness. Objective data includes measurable vital signs and physical findings.

Question 25: The nurse is calculating the infant mortality rate (IMR). Which formula is correct?

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

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 26: A critically ill patient is receiving norepinephrine infusion. The nurse observes blanching and swelling at the IV site. What is the priority action?

Stop the infusion, discontinue the IV, and administer phentolamine subcutaneously to the site (Correct answer)
Flush the IV line with normal saline
Slow the infusion rate and apply warm compress
Switch to dopamine via the same IV

Correct answer: Stop the infusion, discontinue the IV, and administer phentolamine subcutaneously to the site

Norepinephrine extravasation causes tissue necrosis; the infusion must be stopped and phentolamine infiltrated to counteract vasoconstriction.

Question 27: A community nurse is addressing food insecurity in a refugee population. Which Healthy Cities approach best addresses this determinant?

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

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

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

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 29: A patient develops a stage 2 pressure injury. Which description best matches this stage?

Full-thickness tissue loss with exposed bone
Partial-thickness skin loss with exposed dermis (Correct answer)
Full-thickness skin loss with visible subcutaneous fat
Intact skin with non-blanchable erythema

Correct answer: Partial-thickness skin loss with exposed dermis

Stage 2 pressure injuries involve partial-thickness loss of skin with exposed dermis. The wound bed is viable and may appear as a shallow open ulcer or intact/ruptured seroma. Stage 1 shows intact skin with non-blanchable redness.

Question 30: A postoperative patient in a Saudi hospital's PACU develops laryngospasm 15 minutes after extubation. Which is the nurse's PRIORITY intervention?

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

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 31: A nurse is initiating nasogastric (NG) tube feeding for a post-stroke patient in a Saudi hospital. Before starting the first feed, what is the MOST reliable method to confirm correct tube placement?

Auscultating for air sounds while injecting 20 mL of air via the tube
Checking that gastric aspirate has a pH of 6 or less using pH paper
Observing that the patient is not coughing after tube insertion
Chest X-ray confirming the tube tip is below the diaphragm in the stomach (Correct answer)

Correct answer: Chest X-ray confirming the tube tip is below the diaphragm in the stomach

Chest X-ray is the gold standard for confirming NG tube placement, especially before the first feed in a high-risk patient (post-stroke patients have impaired gag reflex and aspiration risk). The auscultation method (whoosh test) is unreliable and no longer recommended. pH testing of aspirate is an acceptable bedside method (pH ≤5.5 confirms gastric placement), but X-ray remains the most reliable method when clinical uncertainty exists.

Question 32: Which action is considered an ethical violation of patient privacy under Saudi health regulations?

Discussing a patient's condition with the treating consultant
Sharing patient images on social media without consent (Correct answer)
Informing public health authorities of a notifiable disease
Providing records to a legal guardian of a minor

Correct answer: Sharing patient images on social media without consent

Sharing identifiable patient information or images on social media without consent violates privacy laws and professional ethics codes.

Question 33: 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
Stop the transfusion immediately, keep the IV line open with normal saline via new tubing, and notify the physician (Correct answer)
Slow the transfusion rate to 50 mL/hr, administer IV diphenhydramine, and continue monitoring
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 34: Which class of drugs is contraindicated in patients with bilateral renal artery stenosis?

Thiazide diuretics
Beta-blockers
Calcium channel blockers
ACE inhibitors and ARBs (Correct answer)

Correct answer: ACE inhibitors and ARBs

ACE inhibitors and ARBs reduce glomerular filtration pressure by dilating the efferent arteriole. In bilateral renal artery stenosis, where perfusion pressure is maintained by angiotensin II, this effect causes acute renal failure. These drugs are contraindicated in this condition.

Question 35: A nurse is assessing a patient and finds the following: BP 90/60, HR 120, RR 24, diaphoresis, and confusion. What condition should the nurse suspect?

Hypovolemic shock (Correct answer)
Anaphylaxis
Hypertensive crisis
Cardiogenic shock

Correct answer: Hypovolemic shock

Hypovolemic shock presents with hypotension, tachycardia, tachypnea, diaphoresis, and altered mental status due to inadequate circulating blood volume. These are classic early-to-late signs of volume depletion.

Question 36: 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
Hold metformin 48 hours before the procedure and restart only after confirming stable renal function post-contrast (Correct answer)
Continue metformin as usual since her eGFR is above 30 mL/min/1.73m², which is the absolute contraindication threshold
Switch metformin to insulin sliding scale 24 hours before the procedure and resume metformin the evening of the procedure

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 37: A 42-year-old female with septic shock secondary to urosepsis is in a SCFHS ICU on norepinephrine 0.25 mcg/kg/min and vasopressin 0.03 units/min. Despite adequate fluid resuscitation (30 mL/kg crystalloid given), her MAP remains 58 mmHg. Her cortisol stimulation test (ACTH stimulation) shows a delta cortisol rise of 150 nmol/L. According to current Surviving Sepsis Campaign guidelines adopted in Saudi Arabia, which intervention is MOST appropriate?

Administer fludrocortisone 50 mcg orally in addition to hydrocortisone
Increase norepinephrine dose to 0.5 mcg/kg/min before adding any corticosteroid
Add hydrocortisone 200 mg/day IV as a continuous infusion (Correct answer)
Switch vasopressin to terlipressin given superior efficacy in septic shock

Correct answer: Add hydrocortisone 200 mg/day IV as a continuous infusion

Per the Surviving Sepsis Campaign 2021 guidelines (adopted by SCFHS and Saudi MOH ICU protocols), hydrocortisone 200 mg/day IV (as continuous infusion or 50 mg q6h) is recommended for septic shock patients who remain hemodynamically unstable despite adequate fluids and vasopressor therapy — regardless of ACTH stimulation test results (the test is no longer used to guide corticosteroid use in septic shock). Adding fludrocortisone is not routinely recommended per current SSC guidelines. Terlipressin is not a standard substitution for vasopressin in septic shock and carries risk of digital ischemia. Increasing norepinephrine first without corticosteroids when already on two vasopressors is not the guideline-recommended sequence.

Question 38: 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 39: A patient on lithium therapy has a serum lithium level of 2.5 mEq/L. The nurse anticipates which clinical finding?

Slight nausea and mild thirst
Coarse tremor, confusion, and seizures (Correct answer)
Mild polyuria and fine hand tremor
Increased urinary output only

Correct answer: Coarse tremor, confusion, and seizures

A lithium level >2.0 mEq/L indicates severe toxicity, presenting with coarse tremors, confusion, seizures, and cardiovascular collapse.

Question 40: A nurse is preparing IV vancomycin 1.5 g in 250 mL NS to infuse over 90 minutes using a 15 gtt/mL IV set. What is the correct manual drip rate in drops per minute?

28 gtt/min
56 gtt/min
42 gtt/min (Correct answer)
35 gtt/min

Correct answer: 42 gtt/min

Rate = 250 mL ÷ 90 min = 2.78 mL/min. Drip rate = 2.78 × 15 gtt/mL ≈ 42 gtt/min. Vancomycin must be infused slowly to prevent Red Man Syndrome — a rate-related adverse reaction (not a true allergy) characterized by flushing and erythema of the face and neck. SFDA and CBAHI-accredited pharmacy protocols in Saudi Arabia mandate a minimum 60-minute infusion for doses ≤ 1 g and 90 minutes for doses > 1 g.

Question 41: A community nurse is using the PRECEDE-PROCEED model for health program planning. What does the PRECEDE phase involve?

Evaluating outcomes after implementation
Assessing needs — identifying factors predisposing, enabling, and reinforcing health behaviors (Correct answer)
Allocating resources and training staff
Implementing the intervention

Correct answer: Assessing needs — identifying factors predisposing, enabling, and reinforcing health behaviors

PRECEDE (Predisposing, Reinforcing, Enabling Constructs in Educational/Ecological Diagnosis and Evaluation) is the assessment phase that identifies why people behave as they do, including predisposing factors (knowledge, beliefs), enabling factors (resources, skills), and reinforcing factors (social support).

Question 42: 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?

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

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 43: A patient is prescribed clopidogrel after coronary stent placement. Which drug combination creates the most dangerous interaction?

Aspirin — additive antiplatelet effect with dual antiplatelet therapy
Omeprazole — reduces clopidogrel activation via CYP2C19 inhibition (Correct answer)
Metoprolol — reduces heart rate and masking of ischemia
Atorvastatin — competes for hepatic metabolism

Correct answer: Omeprazole — reduces clopidogrel activation via CYP2C19 inhibition

Clopidogrel requires hepatic activation by CYP2C19. Proton pump inhibitors (especially omeprazole) strongly inhibit CYP2C19, reducing clopidogrel's active metabolite levels by up to 47%, potentially increasing the risk of in-stent thrombosis. Pantoprazole has less CYP2C19 inhibition.

Question 44: 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?

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

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 45: What is the primary nursing intervention for a neonate with jaundice?

Keep the baby in a dark room
Administer antibiotics
Restrict feeding
Ensure adequate hydration, frequent feeding, monitor bilirubin levels, and prepare for phototherapy if levels are elevated (Correct answer)

Correct answer: Ensure adequate hydration, frequent feeding, monitor bilirubin levels, and prepare for phototherapy if levels are elevated

Neonatal jaundice management: frequent feeding (promotes bilirubin excretion through stool), adequate hydration, monitor serum bilirubin levels, phototherapy (blue light breaks down bilirubin) if levels exceed threshold, protect eyes during phototherapy, and assess skin/sclera color.

Question 46: 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?

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

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 47: A 3-year-old child is brought in with a barking cough, inspiratory stridor, and low-grade fever. Which condition is most likely?

Epiglottitis
Croup (laryngotracheobronchitis) (Correct answer)
Bronchiolitis
Foreign body aspiration

Correct answer: Croup (laryngotracheobronchitis)

The classic triad of barking cough, inspiratory stridor, and low-grade fever in a toddler is characteristic of croup, caused most often by parainfluenza virus.

Question 48: A patient post-gastrectomy experiences dizziness, sweating, and palpitations 30 minutes after eating. This presentation is most consistent with:

Reactive hypoglycemia
Aspiration pneumonia
Anastomotic leak
Dumping syndrome (Correct answer)

Correct answer: Dumping syndrome

Early dumping syndrome occurs 15–30 minutes after eating in post-gastrectomy patients when undigested food rapidly enters the small intestine, causing fluid shifts and vasomotor symptoms like dizziness, sweating, and palpitations.

Question 49: A child weighing 15 kg requires IV fluid resuscitation. The Holliday-Segar formula for maintenance fluids for this child gives:

1,500 mL/day
1,000 mL/day
1,250 mL/day (Correct answer)
750 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 50: A school nurse is implementing a program to prevent teen pregnancy in a Saudi secondary school. Which approach is most culturally appropriate and effective?

Comprehensive reproductive health education aligned with Saudi cultural and religious values, involving family (Correct answer)
Focusing only on abstinence without discussing reproductive health concepts
Distributing contraceptives at the school health clinic
Importing a Western sexual education curriculum directly

Correct answer: Comprehensive reproductive health education aligned with Saudi cultural and religious values, involving family

Effective health education in Saudi Arabia must be culturally and religiously contextual. Programs that involve family, align with Islamic values, and address reproductive health within appropriate cultural frameworks are more accepted and effective than direct adoption of Western models.

Question 51: A Saudi community health nurse is analyzing vital statistics data for a district and notes the following: crude birth rate = 22 per 1,000 population; crude death rate = 6 per 1,000 population; in-migration rate = 8 per 1,000; out-migration rate = 3 per 1,000. What is the net population growth rate per 1,000 population for this district?

21 per 1,000 (Correct answer)
13 per 1,000
16 per 1,000
27 per 1,000

Correct answer: 21 per 1,000

Net population growth rate = (Crude Birth Rate − Crude Death Rate) + (In-migration Rate − Out-migration Rate). Natural increase = 22 − 6 = 16 per 1,000. Net migration = 8 − 3 = 5 per 1,000. Total = 16 + 5 = 21 per 1,000. This formula is essential in community health planning in Saudi Arabia, where expatriate in-migration significantly affects population growth rates and health service demand projections.

Question 52: A patient in a Saudi hospital is found to have carbapenem-resistant Klebsiella pneumoniae (CRKP). What action beyond contact precautions should be taken?

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

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 53: 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: 6,000 units; infusion: 18 units/hr
Bolus: 5,000 units; infusion: 1,000 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 54: A patient is diagnosed with acute respiratory distress syndrome (ARDS). Which ventilator strategy is supported by the strongest evidence?

High tidal volumes (12–15 mL/kg) to maximize alveolar recruitment
Non-invasive BiPAP ventilation as sole support
Low tidal volume ventilation (6 mL/kg ideal body weight) with appropriate PEEP (Correct answer)
High FiO2 (100%) without PEEP to avoid barotrauma

Correct answer: Low tidal volume ventilation (6 mL/kg ideal body weight) with appropriate PEEP

Lung-protective ventilation using low tidal volumes (6 mL/kg ideal body weight) with PEEP is the evidence-based strategy for ARDS, reducing ventilator-induced lung injury.

Question 55: What is the nurse's responsibility regarding high-alert medications in Saudi hospitals?

High-alert medications don't require special protocols
Treat them the same as other medications
Follow additional safety measures including independent double verification, standardized concentrations, and special labeling (Correct answer)
Only pharmacists handle high-alert 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 56: A nurse is preparing a Saudi patient with bipolar I disorder and stage 3 chronic kidney disease (CKD) for discharge on a mood stabilizer regimen. The psychiatrist has prescribed lithium. Which nursing action reflects the HIGHEST level of patient safety advocacy in this specific clinical context?

Administer the prescribed lithium and document the prescription as ordered
Educate the patient on lithium toxicity signs and schedule monthly lithium levels
Substitute lithium with an atypical antipsychotic without notifying the psychiatrist
Immediately clarify the prescription with the psychiatrist and flag the renal contraindication, recommending consideration of valproate or lamotrigine (Correct answer)

Correct answer: Immediately clarify the prescription with the psychiatrist and flag the renal contraindication, recommending consideration of valproate or lamotrigine

Lithium is primarily renally excreted and is relatively contraindicated in stage 3+ CKD due to the high risk of accumulation and toxicity. The nurse's highest advocacy role is to proactively flag this pharmacological risk to the prescribing psychiatrist before the medication is dispensed—not after. While lithium can occasionally be used with extreme caution and adjusted dosing in mild-moderate CKD under specialist oversight, the nurse must initiate the safety conversation. Alternatives such as valproate (with liver monitoring) or lamotrigine are commonly preferred in renal impairment. Substituting medications independently without physician order would exceed the nurse's scope of practice.

Question 57: A patient is admitted involuntarily to a psychiatric unit. The nurse explains that the patient retains which right?

The right to refuse all assessments
The right to leave at any time
No rights, as involuntary admission overrides all rights
The right to refuse specific medications (with capacity assessment) (Correct answer)

Correct answer: The right to refuse specific medications (with capacity assessment)

Involuntary psychiatric admission restricts freedom of movement but does not eliminate all rights. Patients retain rights including: confidentiality, humane treatment, communication with an attorney, and the right to refuse medications in most jurisdictions (unless capacity is deemed absent by a court).

Question 58: The nurse assesses a patient and finds pitting edema in both ankles rated 3+. What does this finding indicate?

The indentation is 1–2 mm deep and rebounds quickly
The indentation is >8 mm and does not rebound
The indentation disappears immediately
The indentation persists for more than 1 minute and is 5–6 mm deep (Correct answer)

Correct answer: The indentation persists for more than 1 minute and is 5–6 mm deep

Pitting edema is graded 1+ to 4+. 3+ edema produces a 5–6 mm pit that persists for more than 1 minute. 4+ edema produces an indentation >8 mm that does not rebound. This grading system helps track fluid overload.

Question 59: What is the nurse's responsibility in fall prevention for hospitalized patients?

Falls are unavoidable in hospitals
Only elderly patients need fall precautions
Fall prevention is the patient's responsibility
Assess fall risk on admission (using validated tool), implement precautions (bed alarm, non-slip footwear, call light within reach), and reassess regularly (Correct answer)

Correct answer: Assess fall risk on admission (using validated tool), implement precautions (bed alarm, non-slip footwear, call light within reach), and reassess regularly

Fall prevention: assess risk on admission using Morse Fall Scale or similar, implement individualized precautions (call light accessible, bed low and locked, non-slip footwear, adequate lighting, toileting schedule), educate patient, and reassess with condition changes or after a fall.

Question 60: A public health nurse is reviewing data showing that cardiovascular disease rates are disproportionately higher in lower-income neighborhoods. This difference is an example of:

A health disparity related to social determinants of health (Correct answer)
A genetic difference in disease susceptibility
Expected biological variation across populations
Random variation in disease distribution

Correct answer: A health disparity related to social determinants of health

Health disparities are preventable differences in disease burden linked to social, economic, and environmental disadvantage. Income, education, neighborhood environment, and access to care are social determinants that drive disparities in cardiovascular disease and other conditions.

Question 61: During the second stage of labor, a multigravida patient's cardiotocograph (CTG) shows a baseline fetal heart rate of 155 bpm, absence of accelerations for 50 minutes, late decelerations with every contraction, and reduced baseline variability of 3 bpm. The cervix is fully dilated and the fetal head is at +2 station. The attending physician is in another delivery. What is the CORRECT sequence of nursing actions per Saudi MOH obstetric emergency protocols?

Continue monitoring and document findings; late decelerations in the second stage are expected and do not require intervention until delivery is complete
Encourage the patient to push with the next contraction to expedite delivery, then reassess CTG
Position patient in left lateral, apply high-flow oxygen via face mask, discontinue oxytocin if infusing, insert IV access, call the obstetrician STAT and activate the emergency response team (Correct answer)
Perform an amnioinfusion to dilute meconium and relieve cord compression before escalating

Correct answer: Position patient in left lateral, apply high-flow oxygen via face mask, discontinue oxytocin if infusing, insert IV access, call the obstetrician STAT and activate the emergency response team

This CTG shows a Category III (non-reassuring/ominous) pattern: late decelerations (uteroplacental insufficiency), absent accelerations, and minimal variability — indicating fetal hypoxia requiring immediate intervention. The nurse's emergency sequence follows the ABCDE obstetric emergency framework: (1) Left lateral position to relieve aortocaval compression, (2) high-flow O₂ to maximize maternal oxygenation, (3) discontinue oxytocin to reduce uterine hyperstimulation, (4) IV access for emergency medications, (5) immediate physician notification and team activation. Pushing with decelerations worsens fetal hypoxia. Amnioinfusion is not a first-line emergency measure. Late decelerations at any stage are never 'expected.'

Question 62: A nurse is administering an intramuscular injection to an adult. Which site is preferred to avoid injury to the sciatic nerve?

Vastus lateralis
Deltoid muscle
Ventrogluteal site (Correct answer)
Dorsogluteal site

Correct answer: Ventrogluteal site

The ventrogluteal site is now preferred for IM injections in adults because it is free of major nerves and blood vessels. The dorsogluteal site is associated with risk of sciatic nerve injury and is no longer recommended.

Question 63: A patient admitted with suspected Ebola hemorrhagic fever requires which level of transmission-based precautions?

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

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 64: 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)
Transfer care to another nurse who is comfortable withholding information
Disclose the diagnosis immediately regardless of family concerns
Agree and withhold all diagnostic information from the patient

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

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

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 66: 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-third of the calculated 24-hour volume
One-quarter of the calculated 24-hour volume
The full 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 67: During a psychiatric home visit supervised by a Saudi community mental health team, a patient with bipolar I disorder on lithium carbonate 900 mg/day reports tremors, polyuria, and mild confusion. His serum lithium level drawn 12 hours post-dose is 1.6 mEq/L. Which nursing intervention is the PRIORITY?

Withhold the next lithium dose immediately and arrange urgent transfer to an emergency department (Correct answer)
Administer the next lithium dose as scheduled and notify the psychiatrist at the next clinic visit
Encourage oral fluid intake of 3 liters per day and reassess in 24 hours
Reduce the lithium dose by half and recheck serum level after 5 days

Correct answer: Withhold the next lithium dose immediately and arrange urgent transfer to an emergency department

A lithium level of 1.6 mEq/L combined with neurological symptoms (confusion, tremor) and renal symptoms (polyuria) represents early-to-moderate lithium toxicity. The therapeutic range is 0.6–1.2 mEq/L for maintenance. At this level with symptom burden, the priority is to withhold the dose immediately and transfer the patient urgently for IV fluids, cardiac monitoring, and possible hemodialysis if levels rise. Encouraging oral fluids alone is insufficient for a symptomatic patient at this level. Continuing the dose is dangerous. Independently halving the dose without medical assessment is outside nursing scope.

Question 68: 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?

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

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 69: 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?

Arrange immediate pasteurization of all unpasteurized milk on the farm and report to the municipality only
Quarantine all household members for 21 days and restrict movement from the property pending veterinary clearance
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

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 70: A patient with obsessive-compulsive disorder (OCD) spends 3 hours daily washing their hands. Which nursing response is most therapeutic?

Tell the patient the behavior is irrational and they should stop
Ignore the behavior completely
Physically prevent the ritual to break the cycle
Allow the ritual initially while working on gradual reduction with a structured ERP plan (Correct answer)

Correct answer: Allow the ritual initially while working on gradual reduction with a structured ERP plan

Exposure and Response Prevention (ERP) is the gold-standard therapy for OCD. Abruptly stopping rituals increases anxiety severely. A structured plan of gradual exposure to anxiety triggers while preventing the ritual (with patient agreement) is the most effective approach.

Question 71: A child with sickle cell disease presents in a vaso-occlusive crisis. Which nursing intervention is the priority?

Prepare for immediate blood transfusion
Apply ice packs to painful extremities
Administer analgesics and encourage IV hydration (Correct answer)
Restrict fluid intake to prevent overload

Correct answer: Administer analgesics and encourage IV hydration

Vaso-occlusive crisis requires adequate pain management with analgesics and vigorous hydration to reduce blood viscosity and restore flow to ischemic tissue.

Question 72: A post-operative patient reports sudden chest pain and shortness of breath on day 2 after hip replacement surgery. The nurse should first suspect:

Myocardial infarction
Pneumonia
Pulmonary embolism (Correct answer)
Pneumothorax

Correct answer: Pulmonary embolism

Sudden chest pain, dyspnea, tachycardia, and hypoxia in a post-orthopedic surgery patient are classic signs of pulmonary embolism (PE) due to deep vein thrombosis (DVT). Virchow's triad (stasis, hypercoagulability, vessel damage) is present post-surgery.

Question 73: A nurse in Saudi Arabia is preparing to administer the MERS-CoV (Middle East Respiratory Syndrome Coronavirus) precaution guidelines to a newly suspected case. Which precautions are required?

Contact precautions with surgical mask
Droplet precautions with surgical mask only
Standard precautions are sufficient for suspected cases
Airborne + Contact + standard precautions; N95 respirator for aerosol-generating procedures (Correct answer)

Correct answer: Airborne + Contact + standard precautions; N95 respirator for aerosol-generating procedures

Saudi MOH and WHO guidelines for MERS-CoV require contact and droplet precautions routinely, with additional airborne precautions (N95) for aerosol-generating procedures. Given the severe outcomes and limited treatment, many Saudi facilities apply full airborne precautions for all MERS-CoV cases.

Question 74: A patient is prescribed metoprolol. What is the most important assessment before administering a beta-blocker?

Respiratory rate and oxygen saturation
Heart rate and blood pressure (Correct answer)
Blood glucose level
Serum potassium 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 75: A neonate born at 34 weeks gestation is at highest risk for which complication related to surfactant deficiency?

Respiratory distress syndrome (Correct answer)
Transient tachypnea of the newborn
Bronchopulmonary dysplasia
Meconium aspiration syndrome

Correct answer: Respiratory distress syndrome

Surfactant deficiency in preterm infants leads to alveolar collapse and respiratory distress syndrome (RDS), most common in infants born before 36 weeks.

Question 76: Which position is recommended for a woman experiencing shoulder dystocia during delivery?

Trendelenburg position
Left lateral decubitus position
McRoberts maneuver (hyperflexion of thighs) (Correct answer)
Lithotomy position with leg abduction

Correct answer: McRoberts maneuver (hyperflexion of thighs)

The McRoberts maneuver involves hyperflexing the maternal thighs onto the abdomen, which flattens the lumbar lordosis and rotates the pubic symphysis to dislodge the impacted shoulder.

Question 77: A nurse observes a patient with borderline personality disorder threatening self-harm after a disagreement with staff. What is the priority intervention?

Leave the patient alone to de-escalate independently
Immediately apply physical restraints
Ensure patient safety and maintain a calm, non-reactive presence (Correct answer)
Discharge the patient from the unit

Correct answer: Ensure patient safety and maintain a calm, non-reactive presence

Safety is the priority; a calm, consistent response avoids reinforcing splitting behavior and reduces escalation.

Question 78: 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 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)
Administer only the oral vaccines today and schedule the injectable vaccines for next week to limit injection-site reactions
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 79: A neurosurgical instrument set used on a patient later confirmed to have Creutzfeldt-Jakob disease (CJD) must undergo prion decontamination. Per the Saudi MOH IPC Manual and WHO guidelines adopted by Saudi facilities, which autoclave protocol is required for these instruments?

Immersion in 2% glutaraldehyde for 10 hours followed by rinsing
Steam sterilization at 134°C for a minimum of 18 minutes (Correct answer)
Standard pre-vacuum steam sterilization at 132°C for 4 minutes
Ethylene oxide (EtO) gas sterilization at standard cycle parameters

Correct answer: Steam sterilization at 134°C for a minimum of 18 minutes

Prions (misfolded proteins causing CJD) are extraordinarily resistant to standard sterilization methods. WHO guidelines — adopted in Saudi MOH IPC manuals for high-risk/prion-contaminated surgical instruments — specify steam sterilization at 134°C for a minimum of 18 minutes in a gravity displacement autoclave (or 18 minutes in a pre-vacuum cycle). Standard 4-minute flash cycles are insufficient. EtO gas and glutaraldehyde do NOT inactivate prions and must never be used as the sole decontamination method for CJD-risk instruments.

Question 80: A patient is placed on contact precautions. Which personal protective equipment (PPE) is required upon entering the room?

N95 respirator and gloves
Gloves and gown (Correct answer)
Mask and gloves
Gown and mask

Correct answer: Gloves and gown

Contact precautions require gloves and a gown to be worn when entering the patient's room, as they prevent transmission of pathogens through direct or indirect contact with the patient or their environment.

Question 81: What are the principles of the nursing code of ethics relevant to Saudi practice?

Ethics only apply in emergency situations
Only following physician orders
Autonomy, beneficence, non-maleficence, justice, veracity, and fidelity — applied within the framework of Islamic healthcare ethics (Correct answer)
Only about salary negotiations

Correct answer: Autonomy, beneficence, non-maleficence, justice, veracity, and fidelity — applied within the framework of Islamic healthcare ethics

Nursing ethics principles: Autonomy (respect patient decisions), Beneficence (do good), Non-maleficence (do no harm), Justice (fair treatment), Veracity (truthfulness), Fidelity (keeping promises). In Saudi Arabia, these align with Islamic values of mercy, justice, and human dignity.

Question 82: What is the purpose of a nursing care plan?

To document billing information for insurance
To provide a individualized, coordinated plan of care based on patient needs (Correct answer)
To record physician orders for nursing staff
To schedule nursing staff assignments

Correct answer: To provide a individualized, coordinated plan of care based on patient needs

A nursing care plan provides an individualized, structured approach to patient care, outlining nursing diagnoses, expected outcomes, and specific interventions tailored to each patient's needs and goals.

Question 83: The nurse is educating a patient with peptic ulcer disease about diet. Which food should the patient avoid?

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

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 84: A patient on a surgical ward develops fever, chills, and hypotension 48 hours after placement of a urinary catheter. The nurse suspects CAUTI. What is the most important immediate nursing action?

Obtain urine culture and blood cultures, notify physician, and monitor vital signs (Correct answer)
Change the urinary catheter immediately
Administer antipyretics and reassess in 4 hours
Irrigate the bladder with normal saline

Correct answer: Obtain urine culture and blood cultures, notify physician, and monitor vital signs

Suspected CAUTI with systemic signs (fever, chills, hypotension) may indicate urosepsis — a medical emergency. Obtaining cultures (urine and blood) before antibiotics are started provides diagnostic information. Immediate physician notification and hemodynamic monitoring are critical.

Question 85: A nurse working in a SCFHS-accredited psychiatric facility in Riyadh is caring for a patient on clozapine therapy for treatment-resistant schizophrenia. On day 18 of therapy, the patient's absolute neutrophil count (ANC) is reported as 1,200 cells/mm³. Per international clozapine monitoring protocols adopted in Saudi practice, what is the CORRECT immediate nursing action?

Withhold clozapine, notify the psychiatrist immediately, and increase ANC monitoring frequency to twice weekly (Correct answer)
Continue clozapine and repeat ANC in 7 days as this value is within normal limits
Reduce the clozapine dose by 50% and recheck ANC in 48 hours
Permanently discontinue clozapine, as any ANC below 1,500 mandates lifelong discontinuation

Correct answer: Withhold clozapine, notify the psychiatrist immediately, and increase ANC monitoring frequency to twice weekly

An ANC of 1,200–1,499 cells/mm³ represents mild neutropenia (Grade 2 alert). Per clozapine monitoring protocols, clozapine must be withheld and the prescribing psychiatrist notified immediately, with ANC rechecked twice weekly until it returns to ≥1,500. Permanent discontinuation is only mandated for severe agranulocytosis (ANC <500). Dose reduction is not a recognized protocol step.

Question 86: A patient with a chest tube is being transported. Which action is correct?

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

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 87: A mechanically ventilated patient's ABG shows: pH 7.50, PaCO2 28 mmHg, HCO3 22 mEq/L. How should the ventilator be adjusted?

Increase FiO2
Increase respiratory rate
Add PEEP
Decrease respiratory rate or tidal volume (Correct answer)

Correct answer: Decrease respiratory rate or tidal volume

The ABG indicates respiratory alkalosis from hyperventilation; decreasing respiratory rate or tidal volume will normalize PaCO2.

Question 88: Which antidote is administered for acetaminophen (paracetamol) overdose?

Flumazenil
N-acetylcysteine (Correct answer)
Naloxone
Atropine

Correct answer: N-acetylcysteine

N-acetylcysteine replenishes glutathione stores, preventing toxic accumulation of NAPQI that causes hepatic necrosis.

Question 89: What is informed consent and what are the nurse's responsibilities?

The nurse obtains consent for surgery
Verbal consent is always sufficient
The nurse ensures the patient understands the procedure, witnesses the consent signature, and documents the process — the physician explains risks/benefits (Correct answer)
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 90: Which medication used to treat hypertension is classified as a calcium channel blocker and primarily affects cardiac conduction?

Amlodipine
Nifedipine
Hydralazine
Verapamil (Correct answer)

Correct answer: Verapamil

Verapamil is a non-dihydropyridine calcium channel blocker that slows SA node automaticity and AV conduction, making it useful for rate control.

Question 91: 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?

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

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 92: A ward manager wants to improve hand hygiene compliance from 55% to the WHO target. Which quality improvement model is most commonly applied in Saudi MOH hospitals for such initiatives?

PDCA (Plan-Do-Check-Act) cycle (Correct answer)
FMEA (Failure Mode and Effects Analysis)
Root Cause Analysis (RCA)
SWOT Analysis

Correct answer: PDCA (Plan-Do-Check-Act) cycle

The PDCA (Plan-Do-Check-Act) cycle is the standard continuous quality improvement model used in Saudi MOH hospitals for process improvement initiatives such as hand hygiene campaigns. FMEA and RCA are used reactively to analyze potential or actual failures, while SWOT is a strategic planning tool, not a QI cycle.

Question 93: The nurse is assessing skin turgor. Where is the best site to assess skin turgor in an adult?

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

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 94: A 58-year-old Saudi male with severe treatment-resistant major depressive disorder with psychotic features is recommended for electroconvulsive therapy (ECT). He has been assessed as lacking decision-making capacity due to profound psychomotor retardation and disorganized cognition. According to SCFHS standards and the Saudi Mental Health Law, which process is REQUIRED before ECT may proceed?

A hospital ethics committee majority vote must be obtained as the sole pathway for ECT authorization in incapacitated patients
The senior consultant psychiatrist may authorize ECT independently by documenting clinical necessity and urgency in the medical record
The Ministry of Health regional director must issue written authorization before ECT can be administered to any patient under a compulsory order
Written informed consent must be obtained from the patient's legal guardian (wali), supported by documentation from at least two psychiatrists confirming the patient's incapacity and the clinical indication (Correct answer)

Correct answer: Written informed consent must be obtained from the patient's legal guardian (wali), supported by documentation from at least two psychiatrists confirming the patient's incapacity and the clinical indication

Under the Saudi Mental Health Law and SCFHS clinical governance standards, ECT is a high-risk, invasive psychiatric procedure that requires formal informed consent. When a patient lacks decision-making capacity, consent authority transfers to the legal guardian (wali). The process requires written consent from the wali alongside formal documentation by at least two psychiatrists establishing the patient's incapacity and the therapeutic indication for ECT. This dual safeguard — guardian consent plus independent psychiatric confirmation — reflects the protective intent of Saudi mental health legislation. Unilateral consultant authorization, ethics committee voting as the sole mechanism, and ministerial authorization do not reflect the correct regulatory pathway.

Question 95: During Ramadan, a Saudi patient with type 2 diabetes mellitus and stable heart failure is managed with metformin, empagliflozin, and bisoprolol. The patient asks the nurse about their medications during the fasting period. Which statement by the nurse is MOST pharmacologically accurate?

All three medications are safe to continue unchanged during Ramadan with no additional monitoring required
Bisoprolol should be doubled in the evening dose to compensate for the missed morning dose during fasting hours
Metformin must be stopped entirely during Ramadan because fasting causes lactic acidosis in all diabetic patients
Empagliflozin should be temporarily discontinued during Ramadan fasting due to risk of euglycemic diabetic ketoacidosis, which may be exacerbated by dehydration and carbohydrate restriction (Correct answer)

Correct answer: Empagliflozin should be temporarily discontinued during Ramadan fasting due to risk of euglycemic diabetic ketoacidosis, which may be exacerbated by dehydration and carbohydrate restriction

SGLT2 inhibitors such as empagliflozin carry a risk of euglycemic diabetic ketoacidosis (euDKA) — a serious complication where DKA occurs with near-normal blood glucose levels, making it easy to miss. Ramadan fasting creates the perfect storm for euDKA: prolonged carbohydrate restriction, relative dehydration, and altered dietary patterns all trigger ketogenesis. Saudi Diabetes Society and international Ramadan-specific diabetes guidelines recommend considering temporary suspension of SGLT2 inhibitors during Ramadan. Metformin does not cause lactic acidosis in well-hydrated patients with adequate renal function — it is generally continued with adjusted timing. Bisoprolol doses must never be arbitrarily doubled; dose redistribution requires physician guidance. Stating no monitoring is required is clinically dangerous.

Question 96: 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
Confront the patient with reality firmly each time
Redirect the patient to a pleasant activity without confirming or dwelling on the death (Correct answer)
Repeatedly explain that the spouse has died each time they ask

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 97: 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?

Isopropyl alcohol 70% alone
Hydrogen peroxide 3%
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 98: The nurse is caring for a patient with Cushing's syndrome. Which assessment finding is expected?

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

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 99: The nurse is preparing to give IV morphine for severe pain. Which side effect must the nurse have equipment ready to manage?

Respiratory depression — have naloxone (Narcan) at bedside (Correct answer)
Hyperglycemia — have insulin available
Hypertension — have antihypertensives ready
Tachycardia — have beta-blockers available

Correct answer: Respiratory depression — have naloxone (Narcan) at bedside

The most dangerous side effect of opioids is respiratory depression, which can be fatal. Naloxone (Narcan) is the opioid antagonist used to reverse respiratory depression. Resuscitation equipment should also be available when administering IV opioids.

Question 100: The nurse is preparing to administer a unit of packed red blood cells (PRBCs). Which solution should be used to prime the IV tubing?

Dextrose 5% in water (D5W)
Normal saline (0.9% NaCl) (Correct answer)
Lactated Ringer's solution
Dextrose 5% in normal saline

Correct answer: Normal saline (0.9% NaCl)

Only normal saline (0.9% NaCl) should be used with blood products. Dextrose solutions cause red blood cell clumping (agglutination), and lactated Ringer's solution contains calcium that can cause clotting. Normal saline is isotonic and compatible with blood.

Question 101: Under the Saudi MOH Expanded Programme on Immunization (EPI) schedule, a healthy 2-month-old infant receives the Pentavalent vaccine (DTP-HepB-Hib). The nurse notes the mother received HBsAg-positive serology results at her antenatal booking visit. Which additional intervention was specifically indicated at birth for this infant, per Saudi national guidelines?

HepB vaccine alone at birth; HBIG is not routinely available in Saudi MOH facilities
Hepatitis B Immunoglobulin (HBIG) 0.5 mL IM within 12 hours of birth, plus first HepB vaccine dose (Correct answer)
Double-dose HepB vaccine at birth without HBIG, given at two separate sites
HBIG alone within 24 hours; defer HepB vaccine until 6 weeks

Correct answer: Hepatitis B Immunoglobulin (HBIG) 0.5 mL IM within 12 hours of birth, plus first HepB vaccine dose

Saudi MOH guidelines and SCFHS nursing standards mandate that infants born to HBsAg-positive mothers receive both HBIG 0.5 mL IM AND the first dose of hepatitis B vaccine within 12 hours of birth at separate injection sites. This dual prophylaxis provides passive-active immunity and reduces vertical transmission risk by over 90%. Delaying HBIG or omitting it entirely significantly reduces efficacy. The pentavalent vaccine at 2 months is a subsequent dose in the series, but the birth intervention was already required.

Question 102: An 80-year-old male patient admitted to a Saudi hospital is found confused at night, agitated, and pulling at his IV line. He was alert on admission 2 days ago. Which condition should the nurse suspect FIRST?

Depression
Normal aging
Dementia
Delirium (Correct answer)

Correct answer: Delirium

The acute onset of confusion in a previously alert elderly patient is characteristic of delirium, not dementia (which has a gradual onset) or depression. Night-time worsening (sundowning pattern) is common in delirium. Immediate assessment for underlying causes — infection, medication toxicity, electrolyte imbalance, and hypoxia — is required. This is never 'normal aging.'

Question 103: A 58-year-old male patient in a Riyadh tertiary care hospital is post-operative day 2 following an open cholecystectomy. He develops sudden onset of dyspnea, pleuritic chest pain, and his SpO₂ drops to 89% on room air. His HR is 118 bpm and BP is 100/70 mmHg. The Wells score is calculated at 7. According to SCFHS nursing standards, which immediate nursing action takes priority BEFORE the physician's order is received?

Administer supplemental oxygen via non-rebreather mask at 10–15 L/min (Correct answer)
Obtain a 12-lead ECG and draw arterial blood gases simultaneously
Position the patient supine with legs elevated to improve venous return
Prepare the patient for immediate surgical embolectomy

Correct answer: Administer supplemental oxygen via non-rebreather mask at 10–15 L/min

In a suspected massive or submassive pulmonary embolism with hypoxemia (SpO₂ 89%), the nurse's first independent action is to restore oxygenation — administering high-flow O₂ via non-rebreather mask at 10–15 L/min is within nursing scope and is the most life-saving immediate step. Positioning supine with legs elevated is contraindicated as it worsens RV strain and can increase thrombus propagation. ECG and ABGs are important but are concurrent physician-driven orders, not the first independent nursing priority. Surgical embolectomy is a physician/surgical decision.

Question 104: What are the common side effects of antipsychotic medications that nurses should monitor?

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

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 105: A child is admitted with suspected epiglottitis. Which nursing action is the highest priority?

Administer oral antibiotics and reassess
Obtain a throat culture before starting treatment
Prepare for lumbar puncture
Do not attempt to visualize the throat or obtain a throat swab (Correct answer)

Correct answer: Do not attempt to visualize the throat or obtain a throat swab

In suspected epiglottitis, examining the throat or causing distress can precipitate complete airway obstruction. The priority is airway management in a controlled setting. Diagnosis is made cautiously; immediate airway protection takes precedence.

Question 106: When assessing cognitive status in an elderly Saudi patient using the Mini-Mental State Examination (MMSE), a score of 20 out of 30 suggests:

Mild cognitive impairment (18–23) (Correct answer)
Severe cognitive impairment (<10)
Moderate cognitive impairment (10–17)
Normal cognition (24–30)

Correct answer: Mild cognitive impairment (18–23)

MMSE interpretation: 24–30 = normal; 18–23 = mild cognitive impairment; 10–17 = moderate; <10 = severe. A score of 20 falls in the mild cognitive impairment range. This finding should prompt further evaluation, a safety assessment, and a care plan that includes fall prevention, medication review, and family education in accordance with Saudi MOH geriatric care standards.

Question 107: A nurse in a Saudi psychiatric inpatient unit is caring for a patient with major depressive disorder who has just completed her sixth electroconvulsive therapy (ECT) session. The patient's family, present during the post-ictal recovery phase, insists on receiving full details of the treatment rationale and potential side effects directly from the nurse. What is the nurse's MOST appropriate response?

Ask the patient, once she has regained orientation, whether she consents to information being shared with her family, then proceed accordingly (Correct answer)
Provide a comprehensive explanation of the ECT procedure, risks, and benefits to the family immediately
Refer the family to the hospital's publicly available ECT brochure and advise them to submit a written information request to administration
Decline to share any clinical information, citing patient confidentiality under Saudi healthcare regulations, and offer to arrange a meeting with the treating psychiatrist

Correct answer: Ask the patient, once she has regained orientation, whether she consents to information being shared with her family, then proceed accordingly

Under Saudi healthcare ethics principles and the Patient Rights Charter (enforced by CBAHI and MOH), patient confidentiality requires explicit consent before disclosing clinical information to family members, even in a collectivist cultural context where family involvement is normative. The correct action is to wait until the patient regains full post-ictal orientation and capacity, then ask her whether she consents to the family being briefed. Sharing information without the patient's knowledge violates her autonomy. A blanket refusal without explanation is unnecessarily dismissive. Referring to a brochure alone does not address the family's legitimate concerns or the clinical communication obligation.

Question 108: A 6-week-old male infant is brought to the ER at a Saudi hospital with a 2-week history of projectile, non-bilious vomiting after feeds. He appears thin with visible gastric peristaltic waves. Sodium is 128 mEq/L, potassium 3.0 mEq/L, chloride 88 mEq/L, and arterial pH 7.52. Which fluid and electrolyte preparation should the nurse anticipate initiating BEFORE surgical correction?

Normal saline (0.9% NaCl) with added potassium chloride (KCl) IV (Correct answer)
5% dextrose in 0.45% NaCl without potassium
Lactated Ringer's solution IV
0.45% NaCl with sodium bicarbonate additive

Correct answer: Normal saline (0.9% NaCl) with added potassium chloride (KCl) IV

Pyloric stenosis causes loss of HCl-rich gastric fluid leading to hypochloremic, hypokalemic metabolic alkalosis (pH 7.52, low Cl, low K). Fluid resuscitation must correct the alkalosis and electrolyte deficits before surgery — premature surgery under alkalosis increases anesthetic risk. Normal saline (0.9% NaCl) replaces chloride to correct the alkalosis, with KCl added once adequate urine output is confirmed. Lactated Ringer's contains lactate which is metabolized to bicarbonate, worsening alkalosis. Sodium bicarbonate would further raise pH, which is contraindicated.

Question 109: A patient is brought to the ED agitated and confused, with dilated pupils, tachycardia, and dry skin. The nurse suspects:

Anticholinergic toxidrome (Correct answer)
Cholinergic crisis
Opioid overdose
Alcohol intoxication

Correct answer: Anticholinergic toxidrome

The anticholinergic toxidrome (from antihistamines, antipsychotics, tricyclic antidepressants) causes dry skin/mucous membranes, mydriasis (dilated pupils), tachycardia, confusion, urinary retention, and fever. Remembered as 'hot as a hare, dry as a bone, blind as a bat, red as a beet, mad as a hatter.'

Question 110: What does the term 'iatrogenic' mean in a clinical context?

Caused by environmental exposure
Caused by the patient's own behavior
Caused by medical treatment or healthcare providers (Correct answer)
Caused by genetic factors

Correct answer: Caused by medical treatment or healthcare providers

Iatrogenic refers to illness, injury, or adverse effects that result from medical examination, treatment, or intervention by healthcare providers. Examples include hospital-acquired infections and medication side effects.

Question 111: 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 are felt only in the abdomen
Contractions become regular, stronger, longer, and closer together (Correct answer)
Contractions decrease in intensity with hydration

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 112: Under the Saudi Mental Health Law (Royal Decree No. M/17 of 2014), a patient with acute psychosis is admitted involuntarily due to imminent risk of harm. The admitting psychiatrist completes an emergency hold. Which statement ACCURATELY reflects the legal requirement that follows the emergency admission under this law?

A formal review by a specialized psychiatric committee of at least two psychiatrists must be conducted, and written justification for continued detention must be documented within the legally specified timeframe (Correct answer)
The patient may be detained indefinitely upon a single psychiatrist's written order, renewable monthly without external review
Voluntary consent must be obtained from the patient within 24 hours; if refused, the patient must be discharged regardless of risk
The hospital director holds sole authority to authorize continued involuntary detention beyond the emergency period without psychiatric committee involvement

Correct answer: A formal review by a specialized psychiatric committee of at least two psychiatrists must be conducted, and written justification for continued detention must be documented within the legally specified timeframe

The Saudi Mental Health Law (Royal Decree No. M/17, 2014) establishes that involuntary admission for emergency psychiatric care must be followed by a formal review conducted by a specialized psychiatric committee comprising at least two psychiatrists. The committee must document clinical justification for ongoing detention within the specified legal period. This safeguard protects patient rights while allowing necessary treatment — reflecting the dual mandate of care and rights protection enshrined in Saudi mental health legislation. Single-physician indefinite detention and director-only authority are inconsistent with this law.

Question 113: A patient develops hypersensitivity reaction after receiving penicillin. Which drug class should the nurse flag as potentially cross-reactive?

Tetracyclines
Cephalosporins (Correct answer)
Macrolides
Fluoroquinolones

Correct answer: Cephalosporins

Penicillins and cephalosporins share a beta-lactam ring structure, and cross-reactivity can occur in patients with penicillin allergy. The risk is approximately 1–2%. Carbapenems also carry a small cross-reactivity risk.

Question 114: A Saudi community health nurse is conducting an epidemiological investigation of tuberculosis (TB) in a densely populated urban district in Riyadh. The nurse identifies an index case — a 35-year-old male worker in a shared labor accommodation. According to the Saudi Ministry of Health TB Control Program guidelines, which contact investigation strategy should be applied FIRST?

Immediate chest X-ray screening for all contacts regardless of symptom status
Universal screening of all residents within a 500-meter radius of the index case's residence
Restricting investigation to contacts who report symptoms of cough lasting more than 2 weeks
Concentric circle approach starting with household and close workplace contacts before expanding to social contacts (Correct answer)

Correct answer: Concentric circle approach starting with household and close workplace contacts before expanding to social contacts

The Saudi MOH TB Control Program follows WHO-aligned contact investigation using the concentric circle (stone-in-pond) approach: prioritizing highest-risk close contacts (household members and prolonged workplace contacts) first, then expanding outward based on infectiousness of the index case. Universal geographic screening is resource-intensive and not evidence-based as a first step. Symptom-based restriction would miss latent TB infection, and universal chest X-ray without risk stratification is not the initial recommended approach.

Question 115: A nurse is reviewing the Saudi MOH 'zero tolerance' HAI targets. Which infection has a zero-tolerance target in Saudi accredited hospitals?

Central line-associated bloodstream infection (CLABSI) in ICUs (Correct answer)
Surgical site infection after elective surgery
Community-acquired urinary tract infection
Catheter-associated UTI in all wards

Correct answer: Central line-associated bloodstream infection (CLABSI) in ICUs

Saudi MOH and accreditation bodies (e.g., CBAHI) set zero-tolerance (zero preventable infections) targets specifically for CLABSI in ICU settings, as evidence shows most CLABSIs are preventable with proper bundle compliance. This drives bundle implementation and surveillance.

Question 116: The Saudi MOH regulations require healthcare workers to report occupational blood or body fluid exposures within what time frame?

Within 72 hours, before starting PEP
Within 1 week
Within 48 hours
Immediately or as soon as possible — within hours, not days (Correct answer)

Correct answer: Immediately or as soon as possible — within hours, not days

Occupational exposure to blood/body fluids requires immediate reporting to the occupational health department because post-exposure prophylaxis (PEP) for HIV must begin within 2 hours (maximum 72 hours) to be effective. Immediate reporting enables timely decision-making.

Question 117: A public health nurse is evaluating the effectiveness of the Saudi Expanded Programme on Immunization (EPI) in a primary health care center. The nurse calculates a vaccination coverage rate of 87% for the pentavalent vaccine (DTP-HepB-Hib) among children under 1 year. According to Saudi MOH herd immunity thresholds and WHO recommendations adopted by the Kingdom, what is the MOST accurate interpretation of this coverage level for pertussis control?

Adequate — 87% exceeds the Saudi MOH minimum threshold of 85% for all EPI vaccines
Insufficient for herd immunity — pertussis requires ≥92–95% coverage to interrupt transmission (Correct answer)
Irrelevant — pertussis herd immunity is not achievable due to waning vaccine immunity in adults
Marginal but acceptable if boosters are confirmed at 18 months and school entry

Correct answer: Insufficient for herd immunity — pertussis requires ≥92–95% coverage to interrupt transmission

Pertussis (whooping cough) has a basic reproduction number (R₀) of 12–17, requiring 92–95% vaccination coverage to achieve herd immunity and interrupt community transmission. An 87% coverage rate, while above many administrative targets, remains below the herd immunity threshold specifically for pertussis — one of the most contagious vaccine-preventable diseases. Saudi Arabia's MOH follows WHO guidance on disease-specific herd immunity thresholds. While booster doses are important for maintaining individual protection, they do not compensate for insufficient primary series coverage at the population level when the threshold is not met.

Question 118: A critically ill patient's serum lactate measures 6 mmol/L. The nurse interprets this finding as indicating:

Adequate tissue perfusion
Tissue hypoperfusion with anaerobic metabolism (Correct answer)
Metabolic alkalosis
Compensated respiratory alkalosis

Correct answer: Tissue hypoperfusion with anaerobic metabolism

A serum lactate above 4 mmol/L indicates anaerobic metabolism resulting from inadequate tissue oxygen delivery, which is commonly seen in shock states.

Question 119: Which electrolyte imbalance is most commonly associated with muscle cramps, tetany, and positive Chvostek's sign?

Hypercalcemia
Hyponatremia
Hyperkalemia
Hypocalcemia (Correct answer)

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 120: 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?

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

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 121: The nurse is assessing a patient with a new colostomy. Which finding should be reported immediately to the physician?

Stoma that is moist and pink-red
Small amount of mucus from stoma
Dark purple, dusky stoma (Correct answer)
Stoma that is slightly raised above skin level

Correct answer: Dark purple, dusky stoma

A dark purple or dusky stoma indicates impaired blood supply and possible necrosis, which is a surgical emergency. A healthy stoma should be moist, pink-red, and slightly raised. Any sign of ischemia requires immediate reporting.

Question 122: A patient with diabetic ketoacidosis (DKA) has blood glucose 480 mg/dL, pH 7.18, HCO3 10 mEq/L, and urine ketones positive. After initial fluid resuscitation, the priority treatment is:

Administer oral metformin
Administer glucagon injection
Infuse sodium bicarbonate
Start a continuous regular insulin infusion (Correct answer)

Correct answer: Start a continuous regular insulin infusion

Continuous regular insulin infusion is the cornerstone of DKA treatment after adequate fluid resuscitation; it suppresses ketogenesis and gradually lowers blood glucose.

Question 123: 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?

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

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 124: 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 vitamin deficiency
Normal weight gain in pregnancy
A type of anemia

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 125: A nurse notices a physician writing orders that appear unsafe for a patient. What is the MOST appropriate initial action?

Refuse all orders from that physician immediately
Call the patient's family to report the concern
Question the physician directly and clarify the rationale for the orders (Correct answer)
Implement the orders without question to avoid conflict

Correct answer: Question the physician directly and clarify the rationale for the orders

Nurses have an ethical and professional duty to question unclear or potentially harmful orders using assertive, respectful communication.

Question 126: A nurse is teaching a pregnant woman about folic acid supplementation. When should supplementation ideally begin?

At least 1 month before conception and through the first trimester (Correct answer)
At the beginning of the third trimester
In the second trimester
Only after pregnancy is confirmed

Correct answer: At least 1 month before conception and through the first trimester

Folic acid (400–800 mcg/day) should be started at least 1 month (ideally 3 months) before conception and continued through the first trimester to prevent neural tube defects, which occur during the first weeks of development, often before pregnancy is known.

Question 127: The nurse is assessing a patient for compartment syndrome after a tibial fracture. Which finding is the earliest indicator?

Pain out of proportion to the injury that is unrelieved by analgesics (Correct answer)
Absent distal pulse
Pallor of the extremity
Paralysis of the foot

Correct answer: Pain out of proportion to the injury that is unrelieved by analgesics

The earliest sign of compartment syndrome is pain that is disproportionate to the injury and not relieved by analgesics — often described as deep, burning, and unrelenting. The 6 P's (pain, pressure, paresthesia, pallor, paralysis, pulselessness) develop progressively, with pain first.

Question 128: When teaching a patient with limited health literacy, the nurse should:

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

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

Non-communicable diseases with special reporting requirements
Occupational diseases requiring employer notification
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 130: A community health nurse is working with a low-income population with high rates of hypertension. According to the social determinants of health framework, which intervention addresses upstream factors?

Providing free blood pressure checks at community events
Advocating for affordable healthy food access and safe exercise spaces (Correct answer)
Educating patients about the DASH diet
Teaching patients how to take blood pressure medications

Correct answer: Advocating for affordable healthy food access and safe exercise spaces

Social determinants of health (SDH) are upstream factors — the conditions in which people live, work, and play. Addressing structural barriers (food insecurity, built environment, poverty) through advocacy is more impactful at the population level than individual-level education.

Question 131: The nurse is teaching a patient about taking oral iron supplements. Which instruction maximizes iron absorption?

Take with a high-fiber meal to maximize absorption
Take with antacids if stomach discomfort occurs
Take with milk to reduce GI upset
Take on an empty stomach or with vitamin C (orange juice) (Correct answer)

Correct answer: Take on an empty stomach or with vitamin C (orange juice)

Iron absorption is maximized in an acidic environment and is enhanced by vitamin C (ascorbic acid). Milk, calcium, antacids, and high-fiber foods reduce iron absorption. Taking iron with vitamin C can increase absorption by 2–3 times.

Question 132: Which antibiotic class is associated with photosensitivity and should be accompanied by sun-avoidance counseling?

Tetracyclines (Correct answer)
Macrolides
Penicillins
Cephalosporins

Correct answer: Tetracyclines

Tetracyclines (e.g., doxycycline) cause photosensitivity reactions; patients must avoid prolonged sun exposure and use sunscreen.

Question 133: 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?

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

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 134: A nurse observes a patient with major depressive disorder beginning to show increased energy and sudden cheerfulness after weeks of profound depression. What is the most important nursing action?

Increase suicide precautions and monitor closely (Correct answer)
Document this as a sign of recovery and reduce observation
Notify the family that the patient is improving
Decrease the antidepressant dose as it is working

Correct answer: Increase suicide precautions and monitor closely

A sudden lift in depression with increased energy can indicate the patient now has enough energy to act on suicidal plans.

Question 135: What is the normal fetal heart rate range during labor monitoring?

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

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 136: What is the nurse's ethical obligation regarding patient confidentiality?

Patient information can be shared with anyone
Social media posts about patients are acceptable without names
Protect all patient health information, share only with authorized care team members on a need-to-know basis, and follow Saudi health data privacy regulations (Correct answer)
Confidentiality only applies to HIV status

Correct answer: Protect all patient health information, share only with authorized care team members on a need-to-know basis, and follow Saudi health data privacy regulations

Nurses must protect all patient information (health data, personal details, images). Information is shared only with authorized healthcare team members directly involved in care. Saudi health data privacy regulations and nursing ethics codes strictly enforce confidentiality.

Question 137: A nurse is conducting a family assessment using the Calgary Family Assessment Model. Which of the following domains does this model assess?

Financial status, employment, and housing only
Structural, developmental, and functional family dimensions (Correct answer)
Individual health histories of each family member
Cultural background and religious practices only

Correct answer: Structural, developmental, and functional family dimensions

The Calgary Family Assessment Model (CFAM) assesses three domains: structural (who is in the family, relationships), developmental (family life cycle stage), and functional (how the family behaves and interacts). It provides a comprehensive systems-based family assessment.

Question 138: A patient is prescribed warfarin for atrial fibrillation. What is the target INR range for this indication?

1.5–2.0
2.0–3.0 (Correct answer)
1.0–1.5
3.0–4.0

Correct answer: 2.0–3.0

For non-valvular atrial fibrillation, the therapeutic INR range for warfarin is 2.0–3.0. This range balances adequate stroke prevention against bleeding risk. A higher range (2.5–3.5) is used for mechanical heart valves.

Question 139: A 44-year-old female patient post-liver transplant at King Faisal Specialist Hospital is on tacrolimus, mycophenolate, and methylprednisolone. On day 7, she develops: temperature 39.2°C, new-onset confusion, right-sided weakness, and a CD4 count of 68 cells/µL. MRI brain shows ring-enhancing lesions with surrounding edema in the basal ganglia. Which opportunistic infection is MOST likely and requires immediate isolation precautions per Saudi infection control guidelines?

Toxoplasma gondii encephalitis — no special isolation beyond standard precautions (Correct answer)
Progressive multifocal leukoencephalopathy (PML) — airborne isolation required
CMV encephalitis — initiate contact-plus precautions
Cryptococcus neoformans meningoencephalitis — place in negative pressure room

Correct answer: Toxoplasma gondii encephalitis — no special isolation beyond standard precautions

Ring-enhancing lesions in the basal ganglia of a severely immunocompromised post-transplant patient (CD4 68) are classic for Toxoplasma gondii encephalitis. Toxoplasmosis is not transmitted person-to-person in immunocompetent contacts; it requires reactivation of latent T. gondii. Therefore, per Saudi MOH and CDC infection control guidelines, standard precautions are sufficient — no special isolation is needed. Cryptococcus presents with meningeal signs and CSF findings, not ring-enhancing lesions, and does not require negative pressure isolation. CMV encephalitis is rare and would not show ring-enhancing lesions; contact-plus is not the standard. PML (JC virus) also does not require airborne isolation and typically shows non-enhancing white matter lesions.

Question 140: The nurse is assessing a postpartum patient on day 2 and notes significant engorgement. What is the most effective comfort measure?

Discontinue breastfeeding to reduce milk production
Feed the infant frequently or pump regularly to empty the breasts (Correct answer)
Wear a tight-fitting bra and restrict fluids
Apply ice packs only and avoid stimulation

Correct answer: Feed the infant frequently or pump regularly to empty the breasts

Frequent emptying of the breasts through nursing or pumping is the most effective treatment for engorgement. Warm compresses before feeding aid let-down; cold compresses after feeding reduce inflammation. Restricting feeds worsens engorgement and can lead to mastitis.

Question 141: The nurse is monitoring a patient receiving IV vancomycin. Which adverse effect requires serum drug level monitoring?

Bone marrow suppression
Peripheral neuropathy
Nephrotoxicity and ototoxicity (Correct answer)
Hepatotoxicity and cholestasis

Correct answer: Nephrotoxicity and ototoxicity

Vancomycin can cause nephrotoxicity (renal damage) and ototoxicity (hearing loss) at elevated serum levels. Trough levels are monitored to ensure therapeutic efficacy while preventing toxicity. AUC/MIC-guided dosing is the current standard.

Question 142: When performing nasopharyngeal suctioning, the nurse should apply suction:

Only while withdrawing the catheter (Correct answer)
Continuously throughout insertion and withdrawal
Only during insertion of the catheter
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 143: 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?

Stop the transfusion → remove the IV line entirely → call a code blue → prepare epinephrine 1:1000
Stop the transfusion → maintain IV access with normal saline → notify the physician and blood bank → send urine and blood samples (Correct answer)
Slow the transfusion rate → notify the physician → obtain vital signs → send the blood bag to the laboratory
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 144: A patient develops urticaria, stridor, hypotension, and angioedema minutes after receiving IV contrast dye. What is the FIRST treatment the nurse should administer?

Methylprednisolone 125 mg IV
Diphenhydramine 50 mg IV
Normal saline 1 L bolus
Epinephrine 0.5 mg IM (1:1000 solution) (Correct answer)

Correct answer: Epinephrine 0.5 mg IM (1:1000 solution)

Epinephrine IM is the life-saving first-line treatment for anaphylaxis; it reverses bronchospasm, reduces angioedema, and restores vascular tone.

Question 145: A nurse is reviewing lab results for a pregnant woman at 28 weeks. Her serum ferritin is 8 ng/mL and hemoglobin is 9.5 g/dL. What should the nurse anticipate ordering?

Oral iron supplementation and dietary iron counseling (Correct answer)
Vitamin B12 injections
Blood transfusion
IV iron infusion immediately

Correct answer: Oral iron supplementation and dietary iron counseling

Low ferritin (depleted iron stores) and low hemoglobin indicate iron deficiency anemia in pregnancy. First-line treatment is oral iron supplementation (elemental iron 150–200 mg/day in divided doses) with dietary counseling. IV iron is reserved for cases of intolerance or non-response to oral therapy.

Question 146: During a shift in a Saudi general hospital, a nurse is caring for a patient with liver cirrhosis and Grade III hepatic encephalopathy who is receiving lactulose via nasogastric tube. The patient develops 6–8 watery stools per day. Arterial blood gas shows: pH 7.51, PaCO₂ 44 mmHg, HCO₃ 34 mEq/L. Which complication is MOST directly linked to these findings?

Metabolic alkalosis exacerbating hepatic encephalopathy by promoting ammonia entry into the CNS (Correct answer)
Metabolic acidosis from excessive stool bicarbonate loss impairing renal ammonium excretion
Respiratory alkalosis worsening ammonia toxicity due to increased cerebral blood flow
Mixed acid-base disorder indicating concurrent lactic acidosis from hepatic failure progression

Correct answer: Metabolic alkalosis exacerbating hepatic encephalopathy by promoting ammonia entry into the CNS

The ABG shows metabolic alkalosis (pH 7.51, elevated HCO₃ 34, normal PaCO₂ — no respiratory compensation yet). Excessive lactulose-induced diarrhea causes significant potassium and chloride loss, leading to hypokalemic, hypochloremic metabolic alkalosis. Alkalosis promotes conversion of ammonium (NH₄⁺, a non-diffusible ion) to ammonia (NH₃, a freely diffusible gas) that readily crosses the blood-brain barrier, paradoxically worsening hepatic encephalopathy. The nurse must notify the physician to adjust lactulose dosing to achieve 2–3 soft stools/day — not 6–8.

Question 147: 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?

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

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 148: The nurse is preparing to administer insulin. The order reads: 'Regular insulin 10 units IV push.' The available vial is U-100 insulin. How many mL should be drawn up?

0.5 mL
1 mL
0.01 mL
0.1 mL (Correct answer)

Correct answer: 0.1 mL

U-100 insulin contains 100 units per mL. Volume = 10 units ÷ 100 units/mL = 0.1 mL. This small volume requires use of an insulin syringe for accuracy. Note: only regular insulin is used IV; NPH and long-acting insulins are not for IV use.

Question 149: In a patient with increased intracranial pressure (ICP), which nursing position is most appropriate?

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

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 150: What is the correct position for breastfeeding to prevent complications?

Baby's body aligned (ear, shoulder, hip in line), facing the breast, with a wide latch covering the areola (Correct answer)
Baby facing away from the mother
Baby lying flat on the bed
Mother lying flat on her back

Correct answer: Baby's body aligned (ear, shoulder, hip in line), facing the breast, with a wide latch covering the areola

Correct breastfeeding position: baby's body aligned (ear-shoulder-hip), tummy to tummy with mother, nose at nipple level, wide mouth latch covering most of the areola (not just nipple), lower lip flanged out, and no clicking sounds during feeding.

Question 151: A patient is prescribed morphine 4 mg IV. The available solution contains 10 mg in 5 mL. How many mL should the nurse administer?

0.4 mL
8 mL
2 mL (Correct answer)
4 mL

Correct answer: 2 mL

Concentration = 10 mg/5 mL = 2 mg/mL. Volume = 4 mg ÷ 2 mg/mL = 2 mL. Alternatively: (4 mg / 10 mg) × 5 mL = 2 mL.

Question 152: A nurse is preparing a critically ill patient for nasogastric tube (NGT) insertion. After insertion, which combination of confirmation methods is considered the gold standard per evidence-based nursing practice guidelines endorsed by SCFHS?

Capnography to rule out tracheal placement combined with epigastric auscultation
pH testing of aspirate alone (pH ≤ 5.5) is sufficient for initial placement confirmation
Auscultation of air insufflation over the epigastrium combined with aspiration of gastric contents
Radiographic confirmation (X-ray) combined with pH testing of aspirate (pH ≤ 5.5) (Correct answer)

Correct answer: Radiographic confirmation (X-ray) combined with pH testing of aspirate (pH ≤ 5.5)

SCFHS and international evidence-based guidelines (including NICE and NPSA) identify radiographic (X-ray) confirmation as the definitive gold standard for NGT placement verification, particularly before first use in high-risk patients. pH testing of aspirate (pH ≤ 5.5 confirms gastric placement) is a validated bedside adjunct. The combination of both provides the highest accuracy. Auscultation of air insufflation alone is no longer considered reliable and has been associated with fatal misplacements. Capnography detects tracheal placement but cannot confirm correct gastric positioning. pH testing alone, while useful, is not considered the gold standard.

Question 153: A patient receiving vancomycin develops a serum trough level of 22 mg/L (target: 10–20 mg/L). The current regimen is 1,250 mg every 12 hours. According to pharmacokinetic principles used in Saudi hospital antimicrobial stewardship programs, what is the MOST appropriate initial nursing action?

Administer the dose and document the result only
Reduce the dose by 250 mg independently and continue dosing
Hold the next dose and notify the physician immediately (Correct answer)
Increase the infusion time from 60 to 90 minutes to lower the trough

Correct answer: Hold the next dose and notify the physician immediately

A vancomycin trough of 22 mg/L exceeds the therapeutic range (10–20 mg/L) and places the patient at risk for nephrotoxicity. The nurse must hold the next scheduled dose and immediately notify the physician or clinical pharmacist for dose adjustment, per SCFHS nursing scope of practice. Independently reducing the dose (option C) is outside the nurse's scope, and simply documenting (option B) or altering infusion time (option D) do not address supratherapeutic levels appropriately.

Question 154: A patient is prescribed dopamine 400 mg in 250 mL D5W to infuse at 5 mcg/kg/min. The patient weighs 80 kg. What is the infusion rate in mL/hr?

15 mL/hr (Correct answer)
30 mL/hr
60 mL/hr
7.5 mL/hr

Correct answer: 15 mL/hr

Step 1: Dose in mcg/min = 5 × 80 = 400 mcg/min. Step 2: Convert to mg/min: 400/1,000 = 0.4 mg/min. Step 3: Concentration = 400 mg/250 mL = 1.6 mg/mL. Step 4: mL/min = 0.4/1.6 = 0.25 mL/min. Step 5: mL/hr = 0.25 × 60 = 15 mL/hr.

Question 155: Which of the following is a primary responsibility of the charge nurse during a mass-casualty incident (MCI) at a Saudi hospital, according to the Saudi MOH Hospital Disaster Plan?

Communicating directly with media and the public
Performing triage at the emergency department entrance
Contacting insurance providers to verify patient coverage
Activating the unit's surge capacity plan and coordinating staff assignments (Correct answer)

Correct answer: Activating the unit's surge capacity plan and coordinating staff assignments

During an MCI, the charge nurse's primary role is to activate the unit's surge capacity plan and coordinate internal staff assignments to receive mass-casualty patients. Triage at the ED entrance is the role of designated triage officers, media communication is handled by the hospital's public relations department, and insurance verification is not an emergency priority.

Question 156: The nurse is caring for a patient with cirrhosis who develops asterixis (liver flap). This finding indicates:

Hepatorenal syndrome
Spontaneous bacterial peritonitis
Hepatic encephalopathy (Correct answer)
Bleeding esophageal varices

Correct answer: Hepatic encephalopathy

Asterixis (flapping tremor of the hands) is a classic sign of hepatic encephalopathy caused by accumulation of ammonia and other toxins that the failing liver cannot clear. It indicates significant neurological impairment from hepatocellular failure.

Question 157: A nurse working in a Saudi hospital ICU is suctioning the endotracheal tube (ETT) of a mechanically ventilated patient using a closed inline suction system. Midway through suctioning, the cardiac monitor alarms and shows a ventricular rate of 38 bpm with wide, bizarre complexes. SpO₂ drops from 97% to 79%. The patient's eyes open and she appears distressed. Which sequence of actions reflects correct prioritisation?

Disconnect the ventilator and begin manual bag-valve-mask ventilation at 15 L/min oxygen before withdrawing the catheter
Complete the suction pass to clear secretions fully before re-oxygenating, as retained secretions are the primary cause of hypoxia
Immediately withdraw the suction catheter, re-oxygenate the patient via the ventilator at 100% FiO₂, call for emergency assistance, and assess for return to baseline before documenting (Correct answer)
Increase PEEP by 5 cmH₂O on the ventilator and administer IV atropine 0.5 mg for the bradycardia while continuing suction

Correct answer: Immediately withdraw the suction catheter, re-oxygenate the patient via the ventilator at 100% FiO₂, call for emergency assistance, and assess for return to baseline before documenting

Vagal stimulation from deep suctioning can cause severe hypoxia and vasovagal bradycardia. The correct priority sequence per SCFHS critical care nursing competencies is: (1) immediately cease suctioning and withdraw the catheter — prolonging suction worsens hypoxia; (2) restore oxygenation by delivering 100% FiO₂ through the closed circuit or ventilator hyperoxgenation; (3) activate the emergency response team. The bradycardia and desaturation are suction-induced, not primary cardiac events, so the most effective intervention is stopping the triggering cause and restoring oxygen. Completing the suction pass or increasing PEEP independently without addressing the immediate hypoxic-vagal crisis escalates the risk of cardiac arrest. Manual BMV disconnects PEEP and risks VAP in this context.

Question 158: Which antiseptic is contraindicated for use on mucous membranes or near the eyes during wound care?

Chlorhexidine gluconate — ototoxic if enters middle ear; causes corneal damage if contacts eye (Correct answer)
Hydrogen peroxide — causes mucous membrane drying only
Povidone-iodine — cannot be used on wounds at all
Normal saline — irritating to mucous membranes

Correct answer: Chlorhexidine gluconate — ototoxic if enters middle ear; causes corneal damage if contacts eye

Chlorhexidine gluconate is contraindicated near the eyes (corneal damage) and must not be allowed to enter the ear canal (ototoxic, causing sensorineural hearing loss if it reaches the middle ear). It should not be used to irrigate wounds near these structures.

Question 159: 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 6 hours of identification
Within 24 hours of identification (Correct answer)
Within 48 hours of identification

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 160: The nurse is following up on a patient with latent tuberculosis infection (LTBI) who has a positive tuberculin skin test but no symptoms. What treatment is typically recommended?

Isoniazid for 9 months (or rifampin for 4 months) (Correct answer)
No treatment, monitoring only
Rifampin, isoniazid, pyrazinamide, ethambutol for 2 months
Combination therapy with 4 drugs for 6 months

Correct answer: Isoniazid for 9 months (or rifampin for 4 months)

LTBI treatment prevents progression to active TB. Standard regimens include isoniazid (INH) for 9 months, or rifampin for 4 months (shorter, better tolerated). Active TB requires the full 4-drug regimen for 6 months.

Question 161: Which layer of the skin contains the sebaceous glands and hair follicles?

Dermis (Correct answer)
Subcutaneous layer
Hypodermis
Epidermis

Correct answer: Dermis

The dermis is the second layer of skin and contains sebaceous (oil) glands, hair follicles, sweat glands, nerves, and blood vessels. It provides structural support and nourishment to the skin.

Question 162: Which of the following is a NANDA-approved nursing diagnostic statement format?

Infection due to surgical wound
Infection secondary to incision
Risk for infection related to impaired skin integrity (Correct answer)
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 163: Which therapeutic communication technique does a nurse use when saying, 'You mentioned feeling hopeless. Can you tell me more about that?'

Summarizing
Voicing doubt
Exploring (Correct answer)
Offering self

Correct answer: Exploring

Exploring encourages the patient to elaborate on a specific topic to gain deeper understanding.

Question 164: A patient's Glasgow Coma Scale score is 8. How should the nurse interpret this finding?

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

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 165: 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
Elevated PAWP with low cardiac output and high SVR
Elevated PAP with normal PAWP and elevated PVR
Equalization of RVEDP, LVEDP, and PAWP within 5 mmHg of each other (Correct answer)

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 166: 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?

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
A patient refusing a scheduled medication after informed refusal counseling
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 167: A nurse is reviewing medications for a patient with renal failure (eGFR 25 mL/min). Which medication requires dose reduction?

Furosemide — dose should be reduced
Metformin — contraindicated; increase in lactic acidosis risk (Correct answer)
Atorvastatin — requires halving the dose
Lisinopril — no dose adjustment needed in renal failure

Correct answer: Metformin — contraindicated; increase in lactic acidosis risk

Metformin is contraindicated (not just dose-reduced) when eGFR is <30 mL/min due to the risk of lactic acidosis from drug accumulation. Furosemide often needs dose increases (not reduction) in renal failure. ACE inhibitors require monitoring but are sometimes continued carefully.

Question 168: What are the developmental milestones a nurse should assess in a 6-month-old infant?

Sitting with support, reaching and grasping objects, babbling, responding to name, and rolling over (Correct answer)
Running and jumping
Speaking in sentences
Walking independently

Correct answer: Sitting with support, reaching and grasping objects, babbling, responding to name, and rolling over

At 6 months, infants should: sit with support (may sit briefly alone), reach and grasp objects (transferring hand to hand), babble consonant sounds ('ba-ba'), recognize familiar faces, respond to name, roll both ways, and show interest in solid foods.

Question 169: 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?

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

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 170: 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?

5 mL
15 mL (Correct answer)
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 171: A nurse is administering IV potassium chloride (KCl) to correct hypokalemia. What is the maximum safe rate for IV KCl administration in a peripheral line?

5 mEq/hour
20 mEq/hour
40 mEq/hour
10 mEq/hour (Correct answer)

Correct answer: 10 mEq/hour

The maximum safe rate for peripheral IV KCl administration is 10 mEq/hour in a concentration of no more than 40 mEq/L. Faster rates can cause cardiac arrhythmias. Central line administration allows higher rates with continuous cardiac monitoring.

Question 172: The nurse is performing a suicide risk assessment. Which factor places the patient at HIGHEST risk?

Recent initiation of antidepressant therapy without other risk factors
Social support and strong religious beliefs
Passive suicidal ideation without a plan
Specific plan with access to means and previous attempt (Correct answer)

Correct answer: Specific plan with access to means and previous attempt

The highest risk factors for completed suicide are: specific plan, access to lethal means, and previous suicide attempt (the strongest predictor). Protective factors include social support and religious beliefs. The combination of plan + means + history represents imminent risk.

Question 173: A 58-year-old male patient 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 on FiO₂ 0.40. The anion gap is 24 mEq/L (Na⁺ 138, Cl⁻ 99, HCO₃⁻ 15). Which of the following is the MOST appropriate next diagnostic step according to SCFHS critical care standards?

Increase the ventilator rate to correct the acidosis
Administer sodium bicarbonate 50 mEq IV immediately
Calculate the delta-delta ratio to determine if a concurrent metabolic alkalosis is masked (Correct answer)
Order a repeat ABG in 4 hours without intervention

Correct answer: Calculate the delta-delta ratio to determine if a concurrent metabolic alkalosis is masked

The ABG shows a high anion gap metabolic acidosis (HAGMA) with an anion gap of 24 (normal 8–12). With a normal PaCO₂, there is no respiratory compensation, suggesting a concurrent process. The delta-delta ratio (ΔAG/ΔHCO₃⁻) = (24–12)/(24–15) = 12/9 ≈ 1.33, which falls in the 1–2 range — indicating a pure HAGMA. However, calculating the delta-delta is the mandatory next step to exclude a mixed disorder before any intervention. Blindly increasing ventilator rate addresses only respiratory parameters and misses the metabolic cause. Sodium bicarbonate is controversial and not first-line in HAGMA without identifying the underlying etiology. Waiting 4 hours is inappropriate in an unstable ICU patient.

Question 174: A competent adult female patient, admitted to a Saudi government hospital, refuses a blood transfusion on religious grounds. Her wali (male guardian) insists the transfusion proceed, arguing he holds legal authority over her medical decisions. Which action is most ethically and legally appropriate under Saudi healthcare regulations?

Delay treatment and request a fatwa from the hospital's Islamic Affairs office before proceeding
Contact the Ministry of Health directly for a binding ruling before taking any clinical action
Proceed with the transfusion based on the wali's authority, documenting his consent in the medical record
Respect the competent patient's refusal, document it thoroughly, and escalate to the treating physician and hospital ethics committee (Correct answer)

Correct answer: Respect the competent patient's refusal, document it thoroughly, and escalate to the treating physician and hospital ethics committee

Under the Saudi Patient Rights and Responsibilities Charter and SCFHS ethical guidelines, a mentally competent adult patient retains the right to refuse treatment regardless of guardian preferences. The wali system grants decision-making authority only for patients who lack capacity. The nurse's role is to document the informed refusal, ensure the patient has received full information, and escalate to the physician and ethics committee — not to override a competent patient's autonomous decision.

Question 175: A 45-year-old female patient in a Saudi hospital ICU step-down unit has been on mechanical ventilation via tracheostomy for 18 days following ARDS. She is being weaned and tolerating pressure support of 8 cmH₂O. The nurse notes that during tracheostomy tube cuff deflation trial, the patient develops audible stridor and increasing respiratory distress within 90 seconds. SpO₂ drops to 92%. Which complication is MOST likely and what is the priority nursing response?

Subglottic or tracheal stenosis causing post-deflation upper airway obstruction; immediately re-inflate the cuff, call the physician, and prepare for bronchoscopy evaluation (Correct answer)
Tracheoesophageal fistula; keep cuff deflated and place the patient in high Fowler's position to reduce aspiration
Tracheomalacia; administer IV methylprednisolone 1 mg/kg stat as prescribed and re-inflate cuff
Vocal cord paralysis; coach the patient to hum and perform voice exercises to reduce laryngospasm

Correct answer: Subglottic or tracheal stenosis causing post-deflation upper airway obstruction; immediately re-inflate the cuff, call the physician, and prepare for bronchoscopy evaluation

Stridor with respiratory distress immediately upon cuff deflation in a long-term tracheostomy patient is a hallmark of subglottic or tracheal stenosis — a known complication of prolonged intubation/tracheostomy, particularly with high cuff pressures exceeding 25–30 cmH₂O. The correct priority response is to re-inflate the cuff to restore the airway seal and oxygenation, then notify the physician urgently. Bronchoscopy (fibre-optic) is the gold standard for diagnosis and planning treatment (e.g., laser resection, stenting, or surgical reconstruction). Tracheomalacia presents with dynamic collapse on expiration — not immediate post-deflation stridor. TEF manifests as food/secretion in the airway, not isolated stridor. Vocal cord paralysis would not respond to cuff deflation in this manner.

Question 176: A nurse is assessing a child with suspected meningitis. Which finding is a positive Kernig's sign?

Neck stiffness
Bulging fontanelle
Flexion of the hip and knee when the neck is flexed
Inability to extend the knee when the hip is flexed to 90 degrees (Correct answer)

Correct answer: Inability to extend the knee when the hip is flexed to 90 degrees

Kernig's sign is positive when the patient cannot fully extend the knee when the hip is flexed at 90 degrees, due to meningeal irritation and hamstring spasm. Brudzinski's sign is when neck flexion causes involuntary hip/knee flexion.

Question 177: A 68 kg patient in a Saudi hospital ICU is prescribed dopamine at 7 mcg/kg/min. The available solution is dopamine 400 mg in 250 mL NS. What is the correct infusion rate in mL/hr?

17.9 mL/hr (Correct answer)
23.6 mL/hr
14.9 mL/hr
29.8 mL/hr

Correct answer: 17.9 mL/hr

First calculate the concentration: 400 mg/250 mL = 1.6 mg/mL = 1600 mcg/mL. Dose required = 7 mcg/kg/min × 68 kg = 476 mcg/min. Convert to mcg/hr: 476 × 60 = 28,560 mcg/hr. Rate = 28,560 ÷ 1600 = 17.85 mL/hr ≈ 17.9 mL/hr. This is a weight-based vasopressor calculation commonly tested at the advanced level.

Question 178: The nurse is assessing a patient's affect. The patient discusses a recent death in the family with no change in facial expression or emotional tone. This is described as:

Restricted affect
Flat affect (Correct answer)
Labile affect
Blunted affect

Correct answer: Flat affect

Flat affect describes the complete absence of emotional expression in voice and face, regardless of the subject matter. Blunted affect is reduced (not absent) emotional expression. Labile affect involves rapid, unpredictable emotional shifts. Both flat and blunted are negative symptoms of schizophrenia.

Question 179: Which of the following actions best demonstrates critical thinking in nursing?

Asking a colleague for advice before every decision
Analyzing patient data to anticipate complications before they occur (Correct answer)
Documenting care after each shift
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 180: 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 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 balloon has been over-inflated; withdraw 5 mL of sterile water and reassess
The catheter has kinked; gently rotate the catheter 90 degrees and check for urine flow
The patient has bladder spasm from the saline; administer an antispasmodic and reassure the patient

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 181: The nurse is caring for a neonate with suspected hypoglycemia. Which clinical sign should the nurse monitor for?

Hypertension and bradycardia
Jitteriness, high-pitched cry, and poor feeding (Correct answer)
Fever and rash
Hematuria and oliguria

Correct answer: Jitteriness, high-pitched cry, and poor feeding

Neonatal hypoglycemia presents with jitteriness/tremors, irritability, high-pitched cry, poor feeding, apnea, cyanosis, and seizures in severe cases. Blood glucose <2.6 mmol/L (<47 mg/dL) in neonates requires prompt treatment.

Question 182: A nurse in a Riyadh tertiary hospital is preparing to perform a central line dressing change on a patient placed under droplet precautions for influenza. Which PPE combination is correct per Saudi MOH/CDC-aligned IPC standards when simultaneously managing the dressing change?

N95 respirator, sterile gloves, sterile gown — eye protection only if splash risk is anticipated
N95 respirator, sterile gloves, sterile gown, and eye protection
Surgical mask, sterile gloves, sterile drape — no gown required since droplets do not contaminate sterile fields
Surgical mask, sterile gloves, sterile gown, and eye protection (Correct answer)

Correct answer: Surgical mask, sterile gloves, sterile gown, and eye protection

When performing an aseptic procedure (central line dressing) on a droplet-precaution patient, Saudi MOH IPC protocols require a surgical mask (adequate for droplet isolation unless aerosol-generating), sterile gloves and sterile gown (required for aseptic technique), and eye protection (standard precaution for any splash-risk procedure). An N95 is not indicated for influenza under droplet precautions unless an aerosol-generating procedure is performed concurrently — a central line dressing change is not aerosol-generating.

Question 183: A Saudi mother brings her 6-week-old male infant to the emergency department. She reports the baby has had forceful, non-bilious projectile vomiting after every feed for the past 5 days and now appears lethargic with dry mucous membranes. Blood gas shows pH 7.51, HCO₃ 34 mEq/L, pCO₂ 48 mmHg, and serum Cl⁻ 88 mEq/L. Which metabolic disturbance is present, and what is the underlying surgical condition?

Mixed alkalosis due to gastroesophageal reflux disease with vagal hypertonicity
Metabolic alkalosis with hypochloremia due to hypertrophic pyloric stenosis (Correct answer)
Metabolic acidosis with hyperchloremia due to Hirschsprung disease
Respiratory alkalosis with compensatory metabolic acidosis due to intestinal malrotation

Correct answer: Metabolic alkalosis with hypochloremia due to hypertrophic pyloric stenosis

The classic metabolic picture of hypertrophic pyloric stenosis (HPS) is hypochloremic, hypokalemic metabolic alkalosis caused by loss of HCl through repeated vomiting. The blood gas confirms metabolic alkalosis (pH 7.51, elevated HCO₃ 34 mEq/L) with respiratory compensation (elevated pCO₂). Low Cl⁻ (88 mEq/L, normal 98–106) confirms hypochloremia. HPS typically presents at 3–6 weeks in first-born males with projectile non-bilious vomiting. The Ramstedt pyloromyotomy is the definitive surgical treatment, after metabolic correction and fluid resuscitation.

Question 184: The nurse is reviewing the principles of aseptic non-touch technique (ANTT). What is the core principle of ANTT?

Key parts (those that would directly contaminate the patient) must never be touched or contaminated (Correct answer)
Only sterile gloves may be used for any invasive procedure
All procedures require a full sterile field
Standard ANTT requires autoclaved equipment for all interventions

Correct answer: Key parts (those that would directly contaminate the patient) must never be touched or contaminated

The core principle of ANTT is protecting 'key parts' (needles, syringe tips, catheter tips, IV line connections) and 'key sites' (insertion sites, wounds) from contamination. Key parts must never be touched and must be protected from environmental contamination.

Question 185: A nurse is managing a 3-day-old neonate born at 37 weeks gestation whose total serum bilirubin (TSB) is 18.5 mg/dL. The infant is exclusively breastfed, has lost 9% of birth weight, and the mother reports the infant is only breastfeeding 6–7 times in 24 hours. The direct (conjugated) bilirubin is 0.4 mg/dL. According to the American Academy of Pediatrics (AAP) phototherapy nomogram used in Saudi practice, which intervention addresses BOTH the hyperbilirubinemia and its underlying cause?

Prepare for exchange transfusion as the bilirubin level exceeds the phototherapy threshold at this gestational age
Discontinue breastfeeding for 48 hours and substitute formula to differentiate breast milk jaundice from breastfeeding jaundice
Initiate phototherapy only; the weight loss is within acceptable limits and does not require intervention
Initiate intensive phototherapy AND support the mother to increase breastfeeding frequency to at least 10–12 feeds per 24 hours, with consideration of supplemental expressed breast milk (Correct answer)

Correct answer: Initiate intensive phototherapy AND support the mother to increase breastfeeding frequency to at least 10–12 feeds per 24 hours, with consideration of supplemental expressed breast milk

This is breastFEEDING jaundice (insufficient intake jaundice), not breast MILK jaundice — distinguished by early onset (day 3), weight loss >7%, and suboptimal feeding frequency. The low conjugated bilirubin rules out cholestasis. At 37 weeks (late preterm), the TSB of 18.5 mg/dL meets phototherapy threshold per the AAP nomogram. The root cause is caloric/fluid deficit from infrequent feeding, so the dual intervention is phototherapy plus aggressive lactation support to increase feeding frequency. Discontinuing breastfeeding is not recommended as the first step; exchange transfusion thresholds are considerably higher (~25–30 mg/dL at 72 hours for term infants).

Question 186: According to the growth chart, a child's weight falls at the 3rd percentile for age. This finding indicates:

A normal variant within two standard deviations
Severe acute malnutrition requiring hospitalization
Morbid obesity risk
The child is below the normal range and needs further assessment (Correct answer)

Correct answer: The child is below the normal range and needs further assessment

A weight at the 3rd percentile is at the lowest boundary of normal; it warrants further assessment for growth faltering, feeding issues, or underlying illness.

Question 187: A community health nurse in Riyadh is conducting MERS-CoV contact tracing following a confirmed case. Investigation reveals two contacts: a neighbor who shared a meal with the index case 16 days ago, and a hospital orderly who performed endotracheal suctioning without appropriate PPE 12 days ago. According to Saudi MOH MERS-CoV surveillance guidelines, which contacts require continued active monitoring?

Only the hospital orderly requires active monitoring, as the neighbor's exposure at 16 days exceeds the maximum 14-day incubation period (Correct answer)
Neither contact requires monitoring, as the standard 10-day incubation window has passed for both
Both contacts require active monitoring until 14 days from their respective last exposures
Only the neighbor requires monitoring due to prolonged close community contact

Correct answer: Only the hospital orderly requires active monitoring, as the neighbor's exposure at 16 days exceeds the maximum 14-day incubation period

Saudi MOH MERS-CoV guidelines follow a 14-day maximum incubation period from last exposure. The neighbor's last exposure was 16 days ago, placing them beyond the monitoring window — no active monitoring is required. The hospital orderly's exposure during an aerosol-generating procedure (high-risk) occurred 12 days ago, meaning 2 days of active monitoring remain. Healthcare worker exposures during AGPs are classified as high-risk contacts regardless of setting and must be monitored to the full 14-day mark.

Question 188: A patient taking a monoamine oxidase inhibitor (MAOI) reports eating aged cheese. The nurse should monitor for:

Hypertensive crisis (Correct answer)
Hypoglycemia
Prolonged QT interval
Respiratory depression

Correct answer: Hypertensive crisis

Tyramine in aged cheese cannot be metabolized when MAO is inhibited, causing a dangerous surge in catecholamines and hypertensive crisis.

Question 189: A nurse is caring for a patient in the ICU who develops ICU psychosis. Which intervention is most effective?

Restrain the patient to prevent self-harm
Reorient the patient frequently, maintain day-night cycles, and reduce sleep disruptions (Correct answer)
Administer high-dose antipsychotics immediately
Place the patient in isolation to reduce stimulation

Correct answer: Reorient the patient frequently, maintain day-night cycles, and reduce sleep disruptions

ICU psychosis (delirium) is best managed non-pharmacologically: frequent reorientation, maintaining circadian rhythms (lights on during day, dim at night), minimizing sleep disruption, early mobility, removing unnecessary catheters/lines, and involving family. This is evidence-based through ABCDEF bundle.

Question 190: When performing the Ballard assessment on a preterm infant, which neuromuscular criterion would suggest the youngest gestational age?

Popliteal angle of 90 degrees
Arm recoil that returns to flexion immediately
Scarf sign: elbow crosses midline without resistance (Correct answer)
Square window: wrist at 90 degrees

Correct answer: Scarf sign: elbow crosses midline without resistance

In the Ballard Maturational Assessment, neuromuscular tone increases with gestational age. The most premature infants have the least tone. A scarf sign where the elbow crosses the midline freely (no resistance) indicates very low gestational age and hypotonia.

Question 191: 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 192: 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
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
Assist the patient to the bathroom with a transfer belt, then notify the physician about the supratherapeutic aPTT

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 193: What is the nurse's role in supporting families of patients with mental illness in Saudi Arabia?

Only provide medication schedules
Educate about the illness, teach coping strategies, connect with support resources, and address cultural stigma sensitively (Correct answer)
Blame the family for the patient's condition
Families should not be involved

Correct answer: Educate about the illness, teach coping strategies, connect with support resources, and address cultural stigma sensitively

Family support includes: psychoeducation about the illness and treatment, teaching communication and coping strategies, connecting to community resources, addressing cultural stigma around mental illness (common in Saudi society), and involving families in treatment planning while respecting patient autonomy.

Question 194: 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?

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

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 195: A 16-year-old female patient at King Abdulaziz Hospital is admitted at 39 weeks gestation with active labor. She is a single mother with no antenatal care documentation. The nurse notes multiple fading bruises on her upper arms and abdomen. The patient becomes tearful when her male companion leaves the room and whispers she is afraid to go home. Under the Saudi Child and Family Protection Society (CFPS) protocols and the Saudi Nursing Code of Ethics, what is the nurse's CORRECT course of action?

Document findings objectively, report to the hospital's social worker and Child and Family Protection Team immediately, and ensure the patient is not left alone with the companion (Correct answer)
Maintain patient confidentiality as she is a legal adult under Saudi law; provide emotional support and discharge safety planning only
Delay reporting until after delivery to avoid stressing the patient during active labor
Confront the companion directly about the bruising to assess the situation before escalating

Correct answer: Document findings objectively, report to the hospital's social worker and Child and Family Protection Team immediately, and ensure the patient is not left alone with the companion

Saudi Arabia has mandatory reporting obligations for suspected domestic violence and child protection concerns through the Child and Family Protection Society (CFPS) and hospital-based protection teams. At 16 years old, this patient is a minor under Saudi law (legal adulthood at 18), making this both a domestic violence and child protection case. The nurse must document objectively (not subjectively), report to the social worker and hospital protection team immediately, and ensure patient safety by not leaving her alone with the suspected abuser. Confronting the abuser is dangerous and delays are not justified by active labor.

Question 196: A 28-year-old Saudi female patient with bipolar I disorder has been stable on lithium carbonate 900 mg/day for 2 years. She presents to the psychiatric clinic reporting polyuria, polydipsia, and a 3-day history of diarrhea and vomiting following a foodborne illness. Her serum lithium level is 2.1 mEq/L. Which clinical presentation would indicate she has progressed to SEVERE lithium toxicity requiring emergency intervention?

Coarse tremor, drowsiness, ataxia, and slurred speech
Polyuria, mild confusion, and a serum lithium of 1.6 mEq/L
Fine hand tremor, nausea, and mild cognitive slowing
Tonic-clonic seizures, deepening coma, and cardiovascular collapse (Correct answer)

Correct answer: Tonic-clonic seizures, deepening coma, and cardiovascular collapse

Severe lithium toxicity (levels >2.0 mEq/L with severe symptoms) manifests as tonic-clonic seizures, impaired consciousness progressing to coma, and cardiovascular collapse — requiring immediate hemodialysis. Fine tremor and nausea are mild toxicity signs. Coarse tremor, ataxia, and drowsiness indicate moderate toxicity. This patient's dehydration from GI illness reduced renal lithium clearance, precipitating toxicity.

Question 197: Which intervention is MOST important in preventing ventilator-associated pneumonia (VAP) in the ICU?

Maintain head-of-bed elevation at 30–45 degrees (Correct answer)
Use a high-flow nasal cannula instead
Change ventilator circuits every 24 hours
Administer prophylactic antibiotics daily

Correct answer: Maintain head-of-bed elevation at 30–45 degrees

Semi-recumbent positioning at 30–45 degrees is a core VAP bundle element that reduces aspiration of oropharyngeal secretions.

Question 198: 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?

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)
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
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 199: 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)
Right ventricular failure
Cardiac tamponade
Fluid overload

Correct answer: Hypovolemia

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

Question 200: The nurse is teaching a mother about the importance of oral rehydration therapy (ORT) for her child with diarrhea. What is the primary advantage of ORT over IV rehydration?

It can be administered at home, is safe, and reduces the need for hospitalization (Correct answer)
It prevents diarrhea recurrence more effectively
It rehydrates faster than IV fluids
It contains more electrolytes than any IV solution

Correct answer: It can be administered at home, is safe, and reduces the need for hospitalization

ORT (WHO/UNICEF recommended ORS formula) is the cornerstone of diarrhea management in the community because it is inexpensive, safe, effective, can be given at home by caregivers, and has dramatically reduced childhood mortality from diarrheal diseases globally.
