,A 65-year-old patient presents with sudden onset dyspnea and unilateral leg swelling. The
PMHNP suspects pulmonary embolism. Which diagnostic test is most definitive?
A. Chest X-ray
B. D-dimer assay
C. CT pulmonary angiography
D. EKG
Answer: C
Rationale: CT pulmonary angiography is the gold standard for diagnosing pulmonary
embolism.
A patient presents with acute chest pain radiating to the jaw, diaphoresis, and nausea. Initial
pharmacologic therapy includes:
A. IV morphine, oxygen, nitroglycerin
B. Oral acetaminophen only
C. Beta-blocker alone
D. IV antibiotics
Answer: A
Rationale: MONA (morphine, oxygen, nitroglycerin, aspirin) supports initial ACS
management.
A patient with chronic kidney disease is prescribed gentamicin. Which laboratory test is
most important to monitor?
A. Liver function tests
B. Serum creatinine and BUN
C. Blood glucose
D. Serum sodium
Answer: B
Rationale: Gentamicin is nephrotoxic; kidney function must be monitored.
A patient with heart failure has an ejection fraction of 28%. Which pharmacotherapy
improves survival?
A. Loop diuretics only
B. ACE inhibitors and beta-blockers
C. Calcium channel blockers
D. NSAIDs
Answer: B
Rationale: ACE inhibitors and beta-blockers reduce mortality in systolic heart failure.
A 72-year-old patient presents with sudden confusion and slurred speech. The most
important initial assessment is:
A. Neurologic exam and CT scan of the head
B. CBC only
C. EKG only
D. Pulmonary function testing
2
, Answer: A
Rationale: Acute stroke must be identified quickly; neurologic exam and imaging are
urgent.
A patient presents with elevated AST and ALT after starting isoniazid. The PMHNP
should:
A. Continue therapy without changes
B. Hold medication and evaluate for hepatotoxicity
C. Switch to rifampin immediately
D. Add acetaminophen
Answer: B
Rationale: Isoniazid can cause hepatotoxicity; labs must be monitored, and medication
may need holding.
A patient with type 2 diabetes presents with fasting glucose 240 mg/dL. Initial
pharmacotherapy includes:
A. Insulin only
B. Metformin
C. Glipizide alone in type 1 diabetes
D. No treatment needed
Answer: B
Rationale: Metformin is first-line therapy for type 2 diabetes unless contraindicated.
A patient presents with tachypnea, crackles, and hypoxia. Arterial blood gas shows PaO2
55 mmHg, PaCO2 32 mmHg, pH 7.48. Interpretation is:
A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic acidosis
D. Metabolic alkalosis
Answer: B
Rationale: Low PaCO2 with elevated pH indicates respiratory alkalosis, commonly from
hyperventilation.
A patient with atrial fibrillation is prescribed warfarin. Which lab test best monitors
anticoagulation?
A. INR
B. PT only
C. Platelet count
D. Hemoglobin
Answer: A
Rationale: INR standardizes prothrombin time for warfarin monitoring.
A 55-year-old patient presents with jaundice, fatigue, and pruritus. Lab tests show elevated
alkaline phosphatase and GGT. Most likely type of liver injury:
A. Hepatocellular
B. Cholestatic
