,Q1. A patient with chronic kidney disease (stage 4) is admitted for acute decompensated heart failure. The
provider orders intravenous furosemide 80 mg bolus, but the patient's serum potassium is 3.2 mEq/L. Which
nursing action is most appropriate?
A. Administer the furosemide as ordered and monitor potassium levels after the dose.
B. Hold the furosemide and notify the provider of the hypokalemia.
C. Administer the furosemide with a potassium-sparing diuretic.
D. Give the furosemide but start a continuous potassium infusion.
Correct Answer: B. Hold the furosemide and notify the provider of the hypokalemia.
Rationale: Hypokalemia (K+ 3.2) increases the risk of cardiac dysrhythmias, especially with loop diuretics that
further deplete potassium. Furosemide should be held and the provider notified for electrolyte repletion before
administration.
Why Wrong:
A - Administering furosemide without addressing hypokalemia risks worsening electrolyte imbalance and
cardiac complications.
C - Potassium-sparing diuretics are not typically combined with loop diuretics acutely and do not correct
existing hypokalemia quickly.
D - Continuous potassium infusion is not standard practice for moderate hypokalemia; repletion should occur
before diuretic administration.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 44; KDOQI Guidelines.
Q2. A patient on a medical-surgical unit develops sudden dyspnea, pleuritic chest pain, and hemoptysis. Vital
signs: BP 100/60, HR 110, RR 28, SpO2 89% on room air. Which diagnostic finding would most strongly
support a diagnosis of pulmonary embolism?
A. Elevated D-dimer with low clinical probability (Wells score <2)
B. Normal D-dimer with high clinical probability
C. Ventilation-perfusion (V/Q) scan showing mismatched defects
D. Chest X-ray showing bilateral infiltrates
Correct Answer: C. Ventilation-perfusion (V/Q) scan showing mismatched defects
Rationale: A V/Q scan showing mismatched defects indicates areas of ventilation without perfusion, classic for
pulmonary embolism. D-dimer is sensitive but not specific; a negative D-dimer with high probability is
contradictory. Chest X-ray is often normal in PE.
Why Wrong:
A - Elevated D-dimer with low clinical probability is less specific and may be false positive; it does not
confirm PE.
B - A normal D-dimer with high clinical probability is inconsistent; D-dimer is highly sensitive, so a negative
result makes PE unlikely.
D - Bilateral infiltrates on chest X-ray are more suggestive of pneumonia or pulmonary edema, not PE.
Reference: Goldhaber, S.Z. (2026). Pulmonary Embolism. In: Harrison's Principles of Internal Medicine, 22nd Ed.
Q3. During a sterile dressing change for a central venous catheter (CVC) insertion site, the nurse notes
purulent drainage and erythema. The patient has a temperature of 38.9°C. What is the priority nursing
intervention?
A. Apply topical antibiotic ointment and change the dressing daily.
B. Obtain a swab culture of the drainage and continue the dressing change.
C. Remove the CVC dressing, apply a sterile gauze, and notify the provider immediately.
D. Flush the CVC with normal saline and administer antipyretics.
Correct Answer: C. Remove the CVC dressing, apply a sterile gauze, and notify the provider immediately.
Rationale: Purulent drainage and fever suggest a catheter-related bloodstream infection (CRBSI). The priority is to
prevent further contamination and notify the provider for possible catheter removal. Culture should be obtained,
Page 3
, but the catheter likely needs removal.
Why Wrong:
A - Topical antibiotics are insufficient for a suspected CRBSI; systemic treatment and catheter removal are often
required.
B - Obtaining a culture is important, but continuing the dressing change without addressing the potential need for
catheter removal delays definitive treatment.
D - Flushing the CVC and giving antipyretics does not address the source of infection and may worsen the condition.
Reference: O'Grady, N.P. et al. (2026). Guidelines for the Prevention of Intravascular Catheter-Related Infections. CDC.
Q4. A patient with type 2 diabetes mellitus is admitted for hyperglycemic hyperosmolar state (HHS). Serum
glucose is 850 mg/dL, serum osmolality 340 mOsm/kg, and urine ketones are negative. Which intravenous
fluid should the nurse prepare to administer first?
A. 0.9% normal saline at 15-20 mL/kg per hour
B. 0.45% normal saline at 250-500 mL per hour
C. 5% dextrose in 0.45% normal saline
D. Lactated Ringer's solution
Correct Answer: A. 0.9% normal saline at 15-20 mL/kg per hour
Rationale: Initial fluid resuscitation for HHS is with 0.9% normal saline to correct hypovolemia and
hyperosmolality. Once hemodynamically stable, the fluid may be changed to 0.45% normal saline. Dextrose
solutions are avoided initially because they increase glucose levels.
Why Wrong:
B - 0.45% normal saline is hypotonic and is used after initial volume expansion with isotonic saline to avoid
rapid shifts in osmolality.
C - 5% dextrose solutions are contraindicated initially because they would exacerbate hyperglycemia.
D - Lactated Ringer's solution contains lactate, which can be converted to glucose and worsen hyperglycemia;
it is not first-line for HHS.
Reference: Kitabchi, A.E. et al. (2026). Hyperglycemic Crises in Adult Patients With Diabetes. Diabetes Care.
Q5. A nurse is teaching a patient about the use of a metered-dose inhaler (MDI) with a spacer for asthma
management. Which patient statement indicates a need for further teaching?
A. I will shake the inhaler for 5 seconds before each use.
B. I will exhale completely, then place the mouthpiece in my mouth and seal my lips around it.
C. After pressing the canister, I will inhale slowly and deeply over 3-5 seconds.
D. I will hold my breath for 10 seconds after inhaling the medication.
Correct Answer: B. I will exhale completely, then place the mouthpiece in my mouth and seal my lips around
it.
Rationale: With a spacer, the patient should place the mouthpiece in the mouth and form a seal, but the correct
technique involves exhaling completely, then pressing the canister to release one puff into the spacer, and
immediately inhaling slowly and deeply. Option B omits the step of pressing the canister after exhalation and
before inhalation, which is critical.
Why Wrong:
A - Shaking the inhaler for 5 seconds is correct to ensure proper mixing of medication.
C - Inhaling slowly and deeply over 3-5 seconds is correct for optimal medication deposition.
D - Holding the breath for 10 seconds allows medication to settle in the airways.
Reference: Global Initiative for Asthma (GINA). (2026). Pocket Guide for Asthma Management.
Q6. A patient with cirrhosis and ascites is prescribed spironolactone. The nurse reviews the laboratory
results: sodium 132 mEq/L, potassium 5.5 mEq/L, creatinine 1.8 mg/dL. Which action should the nurse take?
A. Administer the spironolactone as ordered.
