CMSRN® Certification Exam (Certified Medical-Surgical Registered Nurse) — Questions and Answers

Question 1: When documenting assessment findings in MSNCB practice, which approach is MOST appropriate?

Use technical jargon that only experts can understand
Include only positive findings to maintain optimism
Record objective findings, measurements, and professional observations factually (Correct answer)
Summarize findings verbally without written documentation

Correct answer: Record objective findings, measurements, and professional observations factually

Assessment documentation must be objective, factual, and comprehensive. Recording measurements, observations, and findings without bias ensures that the documentation is useful for decision-making and withstands scrutiny.

Question 2: A nurse caring for a patient receiving IV heparin for NSTEMI notes an aPTT of 200 seconds (therapeutic range 60–100 seconds). The priority intervention is:

Continue the infusion and recheck the aPTT in 6 hours
Obtain a stat platelet count to rule out HIT
Administer protamine sulfate and notify the provider immediately
Reduce the heparin infusion rate per protocol and notify the provider (Correct answer)

Correct answer: Reduce the heparin infusion rate per protocol and notify the provider

A supratherapeutic aPTT requires reducing the heparin infusion rate per protocol and notifying the provider to prevent hemorrhagic complications.

Question 3: During post-cardiac catheterization care, a patient develops sudden severe chest pain, hypotension, and distended neck veins. The nurse should suspect:

Pulmonary embolism
Contrast dye allergic reaction
Cardiac tamponade (Correct answer)
Hematoma at the access site

Correct answer: Cardiac tamponade

The triad of chest pain, hypotension, and distended neck veins (Beck's triad) following a cardiac procedure is classic for cardiac tamponade.

Question 4: What is the role of informed consent in gastrointestinal nursing?

It protects only the provider
It ensures the patient understands and agrees to the plan (Correct answer)
It is a mere formality
It is only needed for surgery

Correct answer: It ensures the patient understands and agrees to the plan

Informed consent ensures patients understand the proposed interventions, alternatives, risks, and benefits before agreeing to proceed.

Question 5: A patient with cirrhosis develops asterixis and confusion. The nurse anticipates which intervention as the priority?

Place a Salem sump tube for gastric decompression
Initiate lactulose therapy (Correct answer)
Restrict dietary sodium to 2 g/day
Administer furosemide IV

Correct answer: Initiate lactulose therapy

Lactulose reduces intestinal ammonia absorption and is the first-line treatment for hepatic encephalopathy.

Question 6: A patient with esophageal varices undergoes endoscopic band ligation. In the immediate post-procedure period, the nurse should prioritize monitoring for:

Spontaneous bacterial peritonitis
Aspiration pneumonia
Esophageal stricture formation
Re-bleeding and hematemesis (Correct answer)

Correct answer: Re-bleeding and hematemesis

Re-bleeding is the most immediate life-threatening complication following esophageal variceal banding.

Question 7: A nurse is preparing a patient for a renal biopsy. Which post-procedure instruction is most critical?

Restrict all fluid intake for 24 hours
Encourage vigorous ambulation within 1 hour
Monitor urine for hematuria and report persistent bleeding (Correct answer)
Apply heat to the biopsy site to reduce discomfort

Correct answer: Monitor urine for hematuria and report persistent bleeding

Renal biopsy carries a risk of hemorrhage; monitoring urine for hematuria and reporting persistent or worsening bleeding is the priority post-procedure intervention.

Question 8: A patient with DKA has an arterial blood gas showing pH 7.18, PaCO2 28 mmHg, HCO3 10 mEq/L. The nurse recognizes this as:

Metabolic acidosis with respiratory compensation (Correct answer)
Respiratory acidosis with metabolic compensation
Metabolic alkalosis with respiratory compensation
Combined respiratory and metabolic alkalosis

Correct answer: Metabolic acidosis with respiratory compensation

DKA causes metabolic acidosis (low pH, low HCO3); the low PaCO2 reflects respiratory compensation (Kussmaul respirations blowing off CO2).

Question 9: A patient with adrenal insufficiency (Addison's disease) is scheduled for surgery. The nurse should anticipate which perioperative intervention?

Withholding all steroids to prevent infection risk
Providing stress-dose corticosteroid coverage (Correct answer)
Restricting IV fluid administration preoperatively
Administering mineralocorticoid supplements only

Correct answer: Providing stress-dose corticosteroid coverage

Patients with adrenal insufficiency cannot mount a normal cortisol stress response, requiring supraphysiologic 'stress-dose' steroids during surgical stress.

Question 10: A nurse is caring for a patient in Buck's traction. Which action is correct?

Ensure the rope moves freely in the pulley with weights hanging freely (Correct answer)
Position the head of bed at 90 degrees
Allow weights to rest on the floor during repositioning
Remove traction for two hours every shift

Correct answer: Ensure the rope moves freely in the pulley with weights hanging freely

Effective skin traction requires that weights hang freely without touching the floor and that the rope moves unobstructed through the pulley.

Question 11: The nurse suspects a patient has developed a pulmonary embolism. Which combination of findings best supports this suspicion?

Gradual onset crackles, fever, and purulent sputum
Bradycardia, hypertension, and productive cough
Barrel chest, pursed-lip breathing, and prolonged expiration
Sudden dyspnea, pleuritic chest pain, and tachycardia (Correct answer)

Correct answer: Sudden dyspnea, pleuritic chest pain, and tachycardia

The classic PE triad includes sudden-onset dyspnea, pleuritic chest pain, and tachycardia, reflecting acute obstruction of pulmonary vasculature.

Question 12: Which electrolyte imbalance is a nurse most likely to find in a patient with prolonged nasogastric suctioning?

Hyponatremia and metabolic acidosis
Hyperkalemia and metabolic acidosis
Hypokalemia and metabolic alkalosis (Correct answer)
Hypernatremia and metabolic acidosis

Correct answer: Hypokalemia and metabolic alkalosis

NG suctioning removes hydrochloric acid and potassium, leading to hypokalemia and hypochloremic metabolic alkalosis.

Question 13: What is the first priority in musculoskeletal care for MSNCB practitioners?

Ensuring patient safety and well-being (Correct answer)
Following insurance requirements
Completing documentation
Meeting productivity targets

Correct answer: Ensuring patient safety and well-being

Patient safety and well-being must always be the first priority in clinical practice, taking precedence over administrative concerns.

Question 14: To prevent aspiration pneumonia in a postoperative patient who is semiconscious, the nurse should:

Position in lateral recovery position until fully alert (Correct answer)
Encourage oral fluids to keep the airway moist
Administer antiemetics prophylactically regardless of symptoms
Position in supine with head flat to reduce aspiration risk

Correct answer: Position in lateral recovery position until fully alert

The lateral (recovery) position allows secretions to drain and prevents aspiration in a semiconscious patient.

Question 15: A patient with prolonged vomiting and nasogastric suction is at greatest risk for which acid-base imbalance?

Respiratory acidosis
Metabolic alkalosis (Correct answer)
Metabolic acidosis
Respiratory alkalosis

Correct answer: Metabolic alkalosis

Loss of hydrochloric acid through vomiting or NG suction removes hydrogen ions from the body, resulting in metabolic alkalosis.

Question 16: A nurse is caring for a patient with AKI in the diuretic (recovery) phase. Which electrolyte imbalance is most likely?

Hyperphosphatemia
Hypokalemia and hyponatremia (Correct answer)
Hyperkalemia
Hypernatremia

Correct answer: Hypokalemia and hyponatremia

During the diuretic phase of AKI, large volumes of urine are excreted, causing loss of potassium and sodium, requiring close electrolyte monitoring and replacement.

Question 17: When assessing a patient for dehydration, which clinical finding is MOST reliable in older adults?

Skin turgor on the back of the hand
Dark yellow urine color alone
Thirst sensation
Skin turgor over the sternum or forehead (Correct answer)

Correct answer: Skin turgor over the sternum or forehead

Skin turgor on the sternum or forehead is more reliable in older adults because peripheral skin loses elasticity with aging, making hand turgor unreliable.

Question 18: Which action is most important when transferring a patient from the OR table to the PACU stretcher?

Remove all monitoring leads before initiating the transfer
Place the patient in Trendelenburg position during the move
Ensure adequate personnel and protect the patient's airway during transfer (Correct answer)
Transfer quickly to minimize patient exposure time

Correct answer: Ensure adequate personnel and protect the patient's airway during transfer

Safe patient transfer requires sufficient personnel to prevent falls and injury, and the airway must be protected throughout the move from OR to PACU.

Question 19: Which ICP waveform component, when elevated above the other components, indicates decreased intracranial compliance?

P3 (dicrotic wave)
P2 (tidal wave) (Correct answer)
P1 (percussion wave)
A-wave (plateau wave)

Correct answer: P2 (tidal wave)

When P2 exceeds P1, it indicates decreased intracranial compliance, meaning the brain has less ability to accommodate changes in volume.

Question 20: Which assessment finding indicates that treatment for diabetic ketoacidosis (DKA) is effective?

Serum potassium rises from 3.0 to 5.5 mEq/L
Blood pressure normalizes and heart rate increases
Serum glucose drops from 480 to 300 mg/dL within 30 minutes
Urine ketones clear and serum bicarbonate rises above 18 mEq/L (Correct answer)

Correct answer: Urine ketones clear and serum bicarbonate rises above 18 mEq/L

Resolution of DKA is confirmed by closure of the anion gap, clearing ketones, and normalization of serum bicarbonate above 18 mEq/L.

Question 21: What is the most important factor in effective communication with patients regarding perioperative nursing?

Question 22: Which position is most appropriate for a patient with increased intracranial pressure (ICP)?

Head of bed elevated 30 degrees, neck midline (Correct answer)
Lateral decubitus with knees flexed
Prone position
Trendelenburg position

Correct answer: Head of bed elevated 30 degrees, neck midline

Elevating the HOB to 30 degrees with the neck in midline promotes venous drainage from the brain, helping to reduce ICP.

Question 23: When caring for a patient with a dislocated hip prosthesis, the nurse should position the affected limb:

In slight abduction and extension pending surgical reduction (Correct answer)
In internal rotation with the hip flexed
Crossed over the unaffected leg for comfort
In adduction across the midline

Correct answer: In slight abduction and extension pending surgical reduction

A dislocated hip prosthesis is immobilized in slight abduction and extension to reduce further tissue injury until closed or open reduction.

Question 24: Which electrolyte imbalance is MOST commonly associated with hyperaldosteronism (Conn's syndrome)?

Hyperkalemia and hyponatremia
Hypomagnesemia and hyperchloremia
Hypokalemia and hypernatremia (Correct answer)
Hyperphosphatemia and hypocalcemia

Correct answer: Hypokalemia and hypernatremia

Excess aldosterone promotes sodium retention and potassium excretion, resulting in hypokalemia and hypernatremia with resultant hypertension.

Question 25: What is the most important factor in effective communication with patients regarding endocrine nursing?

Speaking quickly to save time

Question 27: Which factor MOST significantly affects the quality of technical outcomes in MSNCB practice?

The brand of equipment being used
The speed at which procedures are completed
The practitioner's training, preparation, and attention to detail (Correct answer)
The time of day the procedure is performed

Correct answer: The practitioner's training, preparation, and attention to detail

The quality of technical outcomes depends primarily on the practitioner's level of training, thorough preparation, and careful attention to detail. While equipment matters, the professional's competence is the most significant factor.

Question 28: A patient using an incentive spirometer should be instructed to perform the technique in which way?

Use the device only at night to prevent respiratory fatigue
Exhale forcefully into the device 10 times per hour
Inhale slowly and deeply to raise the piston, hold 3–5 seconds, then exhale (Correct answer)
Breathe rapidly in and out to exercise respiratory muscles

Correct answer: Inhale slowly and deeply to raise the piston, hold 3–5 seconds, then exhale

Slow, sustained maximal inhalation with a 3–5 second breath hold maximizes alveolar recruitment and prevents atelectasis.

Question 29: A patient is diagnosed with carpal tunnel syndrome. Which conservative treatment should the nurse reinforce first?

Surgical decompression
Wrist splinting in neutral position, especially at night (Correct answer)
Hot compresses applied continuously
Strengthening exercises for the wrist flexors

Correct answer: Wrist splinting in neutral position, especially at night

Wrist splinting in neutral position reduces median nerve compression and is first-line conservative management for carpal tunnel syndrome.

Question 30: Which regulatory requirement is UNIVERSAL across all Medical-Surgical Nursing Certification Board practice settings?

Using specific proprietary software systems
Working exclusively during business hours
Maintaining current certification and meeting continuing education requirements (Correct answer)

Question 31: A patient on long-term lithium therapy is at highest risk for which endocrine disorder?

Adrenal insufficiency
Pheochromocytoma
Hyperparathyroidism and hypothyroidism (Correct answer)
Cushing's syndrome

Correct answer: Hyperparathyroidism and hypothyroidism

Lithium commonly causes hypothyroidism by blocking thyroid hormone synthesis and release; it also raises PTH levels, leading to hypercalcemia and hyperparathyroidism.

Question 32: Which finding in a patient receiving peritoneal dialysis (PD) most warrants immediate notification of the physician?

Cloudy peritoneal effluent (Correct answer)
Glucose level of 180 mg/dL
Weight gain of 0.5 kg between exchanges
Mild shoulder discomfort after drainage

Cloudy effluent is the hallmark sign of peritoneal dialysis-associated peritonitis requiring immediate medical intervention.

Question 33: Which sign or symptom indicates uremic encephalopathy in a patient with ESRD?

Asterixis and confusion (Correct answer)
Polydipsia
Peripheral neuropathy only
Pruritus without neurological changes

Correct answer: Asterixis and confusion

Asterixis (flapping tremor) and altered mental status are classic neurological manifestations of uremia affecting the central nervous system.

Question 34: Which laboratory finding is most consistent with a diagnosis of acute pancreatitis?

Elevated direct bilirubin
Decreased serum albumin
Serum lipase >3× upper limit of normal (Correct answer)
Elevated serum alkaline phosphatase

Correct answer: Serum lipase >3× upper limit of normal

Serum lipase elevated more than three times the upper limit of normal is the most sensitive and specific marker for acute pancreatitis.

Question 35: A patient with type 1 diabetes presents with blood glucose of 42 mg/dL, diaphoresis, and confusion. Which intervention should the nurse perform FIRST?

Start an IV and administer 50% dextrose
Notify the physician immediately
Give 15-20g of fast-acting carbohydrate orally (Correct answer)
Administer 1 mg glucagon IM

Correct answer: Give 15-20g of fast-acting carbohydrate orally

If the patient can swallow safely, oral fast-acting carbohydrates (15-20g) are the first-line treatment for mild-to-moderate hypoglycemia.

Question 36: A patient is receiving continuous passive motion (CPM) therapy after TKA. The patient requests to stop due to pain. The nurse should:

Discontinue CPM permanently and notify the surgeon
Stop CPM, administer prescribed analgesic, and restart after pain is controlled (Correct answer)
Increase CPM speed to complete the session faster
Ignore the request because CPM is essential for recovery

Correct answer: Stop CPM, administer prescribed analgesic, and restart after pain is controlled

Pain during CPM should be managed with analgesics before resuming; adequate pain control improves tolerance and outcomes.

Question 37: When documenting assessment findings in MSNCB practice, which approach is MOST appropriate?

Include only positive findings to maintain optimism
Record objective findings, measurements, and professional observations factually (Correct answer)
Summarize findings verbally without written documentation
Use technical jargon that only experts can understand

Correct answer: Record objective findings, measurements, and professional observations factually

Question 38: A patient in the cardiac ICU has a pulmonary artery catheter. The nurse notes a PCWP of 22 mmHg. This finding indicates:

Right ventricular failure with elevated preload
Normal left heart filling pressure
Hypovolemia requiring fluid resuscitation
Elevated left ventricular end-diastolic pressure (Correct answer)

Correct answer: Elevated left ventricular end-diastolic pressure

A PCWP above 18 mmHg reflects elevated left ventricular end-diastolic pressure, indicating left heart congestion and volume overload.

Question 39: A patient taking lithium for bipolar disorder presents with tremors, confusion, and vomiting. Serum lithium level is 2.2 mEq/L. The nurse anticipates which treatment?

Administering sodium bicarbonate IV
Hemodialysis to rapidly remove lithium (Correct answer)
Providing supportive care with oral hydration only
Increasing lithium dose to achieve therapeutic level

Correct answer: Hemodialysis to rapidly remove lithium

Lithium levels >2.0 mEq/L indicate severe toxicity with neurologic symptoms; hemodialysis is the most effective method to rapidly eliminate lithium.

Question 40: A patient presents with ST-segment elevation in leads II, III, and aVF. Which coronary artery is most likely occluded?

Left circumflex artery
Right coronary artery (Correct answer)
Left main coronary artery
Left anterior descending artery

Correct answer: Right coronary artery

ST elevation in II, III, and aVF indicates an inferior wall MI, which is most commonly caused by occlusion of the right coronary artery.

Question 41: A patient with renal artery stenosis is started on an ACE inhibitor. Which laboratory change requires immediate attention?

Decrease in serum potassium below 3.5 mEq/L
Increase in hemoglobin
Decrease in serum sodium
Acute rise in serum creatinine >30% from baseline (Correct answer)

Correct answer: Acute rise in serum creatinine >30% from baseline

A creatinine rise of >30% after starting an ACE inhibitor in renal artery stenosis suggests significant reduction in glomerular filtration pressure, warranting dose adjustment or discontinuation.

Question 42: In MSNCB practice, when should a patient's condition be reassessed?

Once per week
At regular intervals and when status changes (Correct answer)
Only when the patient requests it
Only at admission and discharge

Correct answer: At regular intervals and when status changes

Regular reassessment and reassessment upon status changes ensure that care plans remain appropriate and responsive to the patient's needs.

Question 43: A nurse is assessing a patient with suspected appendicitis. Which finding is described as Rovsing's sign?

Increased RLQ pain with internal rotation of the right hip
Pain in the RLQ when the left lower quadrant is palpated (Correct answer)
RLQ pain elicited by elevation of the right leg against resistance
Tenderness at McBurney's point on direct palpation

Correct answer: Pain in the RLQ when the left lower quadrant is palpated

Rovsing's sign is RLQ pain that occurs when pressure is applied to the left lower quadrant, suggesting peritoneal irritation.

Question 44: What is the MOST important factor to consider when selecting assessment tools for MSNCB certification work?

How quickly the tool can be administered
Personal familiarity with the tool
The cost of the assessment tool
Validity, reliability, and appropriateness for the specific context (Correct answer)

Question 45: Which diet modification is most appropriate for a patient with diverticulosis (no active diverticulitis)?

Clear liquid diet long-term
Low-fiber, low-residue diet
High-protein, low-carbohydrate diet
High-fiber diet with adequate fluid intake (Correct answer)

Correct answer: High-fiber diet with adequate fluid intake

A high-fiber diet softens stool and reduces intraluminal pressure, decreasing the risk of diverticular inflammation.

Question 46: Which approach to endocrine nursing is considered best practice in current MSNCB standards?

Evidence-based, individualized interventions (Correct answer)
Traditional methods exclusively
One-size-fits-all protocols
The least expensive option

Correct answer: Evidence-based, individualized interventions

Evidence-based, individualized interventions combine the best available research with patient-specific factors for optimal outcomes.

Question 47: A patient with GERD is prescribed omeprazole. The nurse should instruct the patient to take this medication:

30–60 minutes before the first meal of the day (Correct answer)
With food to reduce GI upset
At bedtime with a full glass of water
As needed when heartburn symptoms occur

Correct answer: 30–60 minutes before the first meal of the day

Proton pump inhibitors are most effective when taken 30–60 minutes before a meal so the drug is active when acid pumps are stimulated.

Question 48: A patient with type 2 diabetes is ordered a fasting lipid panel. The nurse knows the patient's LDL target should be less than:

100 mg/dL (Correct answer)
200 mg/dL
130 mg/dL
160 mg/dL

Correct answer: 100 mg/dL

ADA guidelines recommend LDL <100 mg/dL for most patients with diabetes, or <70 mg/dL for those with cardiovascular disease.

Question 49: In MSNCB practice, when should a patient's condition be reassessed?

Once per week
Only at admission and discharge
At regular intervals and when status changes (Correct answer)
Only when the patient requests it

Correct answer: At regular intervals and when status changes

Regular reassessment and reassessment upon status changes ensure that care plans remain appropriate and responsive to the patient's needs.

Question 50: A nurse is caring for a patient 6 hours post-total hip arthroplasty (THA). Which position is contraindicated?

Hip flexion greater than 90 degrees (Correct answer)
Hip abduction with a pillow between legs
Supine with head of bed at 30 degrees
Leg in neutral rotation

Correct answer: Hip flexion greater than 90 degrees

Hip flexion beyond 90 degrees risks prosthetic dislocation in the early postoperative period after posterior-approach THA.

Question 51: Which Glasgow Coma Scale score indicates severe traumatic brain injury?

8 or below (Correct answer)
9-12
13-15
6 or below

Correct answer: 8 or below

A GCS score of 8 or below classifies a traumatic brain injury as severe and typically requires intubation to protect the airway.

Question 52: A postoperative patient uses a PCA pump and reports uncontrolled pain at level 8/10. The nurse assesses that the patient is not pressing the button correctly. The appropriate intervention is:

Switch to IM opioids for better pain control
Educate the patient on proper PCA use and assess for barriers (Correct answer)
Override the lockout and administer an extra bolus
Document and notify the physician that PCA is ineffective

Correct answer: Educate the patient on proper PCA use and assess for barriers

Patient education on correct PCA use addresses the root cause of underutilization before escalating to other analgesic routes.

Question 53: Which intervention is the PRIORITY for a patient in thyroid storm (thyrotoxic crisis)?

Prepare patient for immediate thyroidectomy
Administer radioactive iodine therapy
Apply warming blankets to treat hypothermia
Administer propylthiouracil (PTU) and propranolol (Correct answer)

Correct answer: Administer propylthiouracil (PTU) and propranolol

Thyroid storm treatment prioritizes blocking new thyroid hormone synthesis with PTU and controlling sympathetic symptoms with propranolol.

Question 54: The nurse is preparing to administer regular insulin IV for a patient in DKA. Which action is MOST important before beginning the infusion?

Ensure the patient has eaten a full meal
Obtain a 12-lead ECG before starting any insulin
Administer sodium bicarbonate to correct acidosis first
Check serum potassium level and correct if below 3.5 mEq/L (Correct answer)

Correct answer: Check serum potassium level and correct if below 3.5 mEq/L

Insulin drives potassium intracellularly; if potassium is already low (<3.5 mEq/L), insulin administration can cause life-threatening hypokalemia.

Question 55: Which finding in a patient with a cervical spinal cord injury indicates the development of neurogenic shock?

Hypotension and tachycardia
Hypertension and bradycardia
Hypertension and tachycardia
Hypotension and bradycardia (Correct answer)

Correct answer: Hypotension and bradycardia

Neurogenic shock results from disrupted sympathetic pathways, causing hypotension and paradoxical bradycardia without compensatory tachycardia.

Question 56: A nurse is assessing a patient who sustained a crush injury to the leg 8 hours ago. Creatine kinase (CK) is 28,000 U/L and urine is dark brown. The priority nursing concern is:

Hypothermia
Hypernatremia from IV fluid administration
Acute kidney injury from myoglobinuria (Correct answer)
Compartment syndrome in the contralateral leg

Correct answer: Acute kidney injury from myoglobinuria

Markedly elevated CK and dark urine indicate rhabdomyolysis; myoglobin precipitates in renal tubules, causing acute kidney injury requiring aggressive IV hydration.

Question 57: A patient recovering from a partial gastrectomy develops diaphoresis, palpitations, and dizziness 20 minutes after eating. The nurse recognizes this as:

Late dumping syndrome
Marginal ulcer formation
Early dumping syndrome (Correct answer)
Anastomotic leak

Correct answer: Early dumping syndrome

Early dumping syndrome occurs within 15–30 minutes of eating due to rapid emptying of hyperosmolar chyme into the small intestine.

Question 58: Which dietary recommendation is appropriate for a CKD patient to slow disease progression?

Unrestricted protein with increased caloric intake
High-protein diet to prevent muscle wasting
Plant-based protein avoided due to phosphorus content
Moderate protein restriction (0.6–0.8 g/kg/day) (Correct answer)

Correct answer: Moderate protein restriction (0.6–0.8 g/kg/day)

Moderate protein restriction (0.6–0.8 g/kg/day) reduces uremic toxin production and glomerular hyperfiltration, slowing CKD progression.

Question 59: When administering nimodipine to a patient with subarachnoid hemorrhage, the primary purpose is to:

Reduce intracranial pressure
Dissolve the blood clot in the subarachnoid space
Prevent cerebral vasospasm (Correct answer)
Control seizure activity

Correct answer: Prevent cerebral vasospasm

Nimodipine, a calcium channel blocker, is given after subarachnoid hemorrhage specifically to prevent cerebral vasospasm and reduce neurological deficits.

Question 60: A nurse is caring for a patient after coronary artery bypass graft (CABG) surgery. Which finding in the first 24 hours requires the most immediate attention?

Mediastinal drainage suddenly decreasing to 5 mL/hr (Correct answer)
Chest tube drainage of 80 mL/hr
Serum glucose of 160 mg/dL
Temperature of 37.8°C (100°F)

Correct answer: Mediastinal drainage suddenly decreasing to 5 mL/hr

Sudden decrease in mediastinal drainage after CABG may indicate tube occlusion and impending cardiac tamponade, requiring immediate assessment.

Question 61: When applying electrosurgical unit (ESU) grounding pad to a patient, which site is most appropriate?

Over well-vascularized muscle mass close to the operative site (Correct answer)
Over a bony prominence such as the hip
On the patient's back regardless of the surgical site
Over a site with a tattoo for better conductivity

Correct answer: Over well-vascularized muscle mass close to the operative site

The ESU grounding pad should be placed on a well-vascularized, fleshy area close to the operative site to ensure even current distribution and prevent burns.

Question 62: A nurse is preparing to administer ipratropium bromide to a patient with COPD. Which assessment finding is a contraindication for this medication?

History of narrow-angle glaucoma (Correct answer)
Blood pressure of 142/88 mmHg
Serum potassium of 3.8 mEq/L
Heart rate of 88 beats per minute

Correct answer: History of narrow-angle glaucoma

Ipratropium, an anticholinergic, can increase intraocular pressure and is contraindicated in narrow-angle glaucoma; closed-angle glaucoma crisis can result from systemic or inhaled anticholinergics.

Question 63: In Medical-Surgical Nursing Certification Board, what is the PRIMARY purpose of conducting regular safety drills and exercises?

To evaluate employee performance reviews
To satisfy insurance requirements only
To ensure personnel can respond effectively in emergencies (Correct answer)
To reduce daily workload

Correct answer: To ensure personnel can respond effectively in emergencies

Regular safety drills ensure that all personnel are prepared to respond effectively during actual emergencies. Practice builds muscle memory, identifies gaps in emergency procedures, and improves overall response times.

Question 64: Which stool characteristic is most associated with an upper GI bleed?

Ribbon-shaped stool
Bright red blood per rectum
Clay-colored stool
Tarry, black, malodorous stool (Correct answer)

Correct answer: Tarry, black, malodorous stool

Melena (tarry, black, malodorous stool) results from digestion of blood as it transits the GI tract from an upper source.

Question 65: A nurse is educating a patient about activity restrictions following acute MI. Which statement by the patient indicates correct understanding?

I will gradually increase my activity level and follow the cardiac rehabilitation program. (Correct answer)
I can return to heavy lifting and strenuous exercise within two weeks.
I can resume all normal activities once my chest pain is gone.
I should remain on bed rest for at least four weeks to allow complete healing.

Correct answer: I will gradually increase my activity level and follow the cardiac rehabilitation program.

Graduated activity progression through a structured cardiac rehabilitation program is the evidence-based approach to safely restoring function after acute MI.

Question 66: When a MSNCB professional identifies a potential regulatory violation, the CORRECT first step is to:

Document the violation and report it through proper channels (Correct answer)
Address it only if directly affected
Wait to see if it resolves on its own
Discuss it casually with coworkers

Correct answer: Document the violation and report it through proper channels

Proper documentation and reporting through established channels is the correct first step when identifying a potential violation. This ensures accountability, creates a paper trail, and allows appropriate parties to investigate and resolve the issue.

Question 67: A patient returns from the OR after open reduction internal fixation (ORIF) of the radius. What is the priority neurovascular assessment?

Assess respiratory rate and oxygen saturation
Monitor blood glucose every 4 hours
Check pulses, sensation, and movement of the fingers distal to the injury (Correct answer)
Assess the patient's ability to move the shoulder

Correct answer: Check pulses, sensation, and movement of the fingers distal to the injury

Neurovascular assessment distal to a fracture or surgical site detects early compartment syndrome or vascular injury.

Question 68: A renal transplant patient is prescribed tacrolimus. Which adverse effect requires regular laboratory monitoring?

Pulmonary fibrosis
Severe hypokalemia
Bone marrow stimulation causing polycythemia
Nephrotoxicity and neurotoxicity (Correct answer)

Correct answer: Nephrotoxicity and neurotoxicity

Tacrolimus is a calcineurin inhibitor with dose-dependent nephrotoxicity and neurotoxicity; trough levels and renal function must be monitored closely.

Question 69: Which symptom cluster in a post-thyroidectomy patient should prompt the nurse to assess for laryngeal nerve damage?

Neck swelling, pain, and difficulty swallowing
Tachycardia, fever, and extreme agitation
Perioral tingling and carpopedal spasm
Hoarse voice, difficulty speaking, and stridor (Correct answer)

Correct answer: Hoarse voice, difficulty speaking, and stridor

Hoarseness, weak voice, and stridor after thyroidectomy suggest recurrent laryngeal nerve injury, which can compromise the airway.

Question 70: Which nursing intervention is highest priority when caring for a patient in the immediate postoperative period following a hemorrhoidectomy?

Assess pain level and administer analgesics before bowel movements (Correct answer)
Administer a Fleet enema to cleanse the operative area
Apply a rectal tube to minimize pressure on the surgical site
Encourage ambulation every 2 hours

Correct answer: Assess pain level and administer analgesics before bowel movements

Pain management prior to bowel movements is critical to prevent fecal retention, constipation, and wound dehiscence after hemorrhoidectomy.

Question 71: Which acid-base disturbance is most characteristic of ESRD?

Respiratory acidosis
Metabolic alkalosis
Respiratory alkalosis
Metabolic acidosis with elevated anion gap (Correct answer)

Correct answer: Metabolic acidosis with elevated anion gap

ESRD impairs renal acid excretion and bicarbonate regeneration, resulting in high anion gap metabolic acidosis.

Question 72: A patient with acute kidney injury (AKI) has a urine output of 25 mL/hour for the past 3 hours. How should the nurse classify this finding?

Normal urine output
Oliguria requiring evaluation (Correct answer)
Anuria requiring urgent intervention
Polyuria suggesting recovery phase

Correct answer: Oliguria requiring evaluation

Oliguria is defined as urine output <0.5 mL/kg/hr or <30 mL/hr in adults, warranting prompt clinical evaluation.

Question 73: Which approach is MOST important for MSNCB professionals when applying technical procedures?

Adhering to established protocols while adapting to specific conditions (Correct answer)
Applying the same technique in every situation without variation
Using the fastest method available regardless of standards

Question 147: Which nursing action is MOST appropriate for a patient with myxedema coma?

Administer high-dose propranolol to control heart rate
Administer cooling blankets and acetaminophen for fever
Restrict IV fluids to prevent cerebral edema
Provide IV thyroid hormone, keep warm, and monitor for respiratory failure (Correct answer)

Correct answer: Provide IV thyroid hormone, keep warm, and monitor for respiratory failure

Myxedema coma requires IV thyroid hormone replacement, external rewarming, airway support, and close monitoring for respiratory failure due to decreased respiratory drive.

Question 148: What is the role of informed consent in cardiac nursing?

It is only needed for surgery
It protects only the provider
It ensures the patient understands and agrees to the plan (Correct answer)
It is a mere formality

Correct answer: It ensures the patient understands and agrees to the plan

Question 149: A patient with a new diagnosis of Crohn's disease asks about surgical cure. The nurse's best response is:

Surgery is not an option for Crohn's disease
Surgery controls complications but does not cure Crohn's disease, as it can recur (Correct answer)
Surgery cures Crohn's disease by removing the affected bowel segment
A colectomy with ileostomy permanently eliminates Crohn's disease

Correct answer: Surgery controls complications but does not cure Crohn's disease, as it can recur

Unlike ulcerative colitis, Crohn's disease is not cured by surgery and frequently recurs at or near the anastomosis.

Question 150: What is the first priority in gastrointestinal nursing for MSNCB practitioners?

Following insurance requirements
Meeting productivity targets
Ensuring patient safety and well-being (Correct answer)
Completing documentation

Correct answer: Ensuring patient safety and well-being
