APEA 3P / FNP CLINICAL PROFICIENCY
HIGH-YIELD ADVANCED TEST BANK
110 Challenging MCQs with Answers & Detailed Rationales
Important: These are original questions created from the concepts and high-yield topics
represented in the supplied study materials. They are not presented as leaked or reproduced
APEA examination questions.
SECTION I — CARDIOVASCULAR
Question 1
A 72-year-old man reports progressive exertional dyspnea, chest pressure, and two episodes of
near-syncope while walking uphill. Examination reveals a harsh crescendo-decrescendo systolic
murmur at the right upper sternal border radiating to the carotids. Which diagnosis is most
likely?
A. Mitral regurgitation
B. Aortic stenosis
C. Mitral stenosis
D. Aortic regurgitation
Correct answer: B. Aortic stenosis
Rationale: Aortic stenosis classically produces a harsh systolic crescendo-decrescendo murmur
at the right upper sternal border with radiation to the carotids. The classic symptomatic triad is
angina, syncope, and dyspnea/heart failure. Symptomatic severe aortic stenosis requires
prompt cardiology evaluation. Mitral regurgitation is usually holosystolic at the apex and
radiates toward the axilla.
Question 2
A patient has a holosystolic murmur best heard at the apex that radiates to the left axilla. Which
valvular lesion is most likely?
A. Aortic stenosis
B. Mitral stenosis
,C. Mitral regurgitation
D. Aortic regurgitation
Correct answer: C. Mitral regurgitation
Rationale: Mitral regurgitation causes backward flow from the left ventricle into the left atrium
during systole, producing a holosystolic murmur at the apex with radiation to the axilla. This
classic finding is specifically emphasized in the supplied clinical-proficiency material.
Question 3
A 64-year-old woman has a low-pitched diastolic rumble at the apex accompanied by an opening
snap. Which condition should the NP suspect?
A. Mitral stenosis
B. Mitral regurgitation
C. Aortic stenosis
D. Aortic regurgitation
Correct answer: A. Mitral stenosis
Rationale: Mitral stenosis produces a low-pitched diastolic rumbling murmur, best heard at
the apex, often with an opening snap. Chronic rheumatic heart disease most commonly affects
the mitral valve. The supplied materials specifically identify the mitral valve as the valve most
commonly involved in chronic rheumatic disease.
Question 4
A patient with longstanding hypertension has a laterally displaced point of maximal impulse.
Which pathophysiologic change best explains this finding?
A. Right ventricular dilation
B. Left ventricular hypertrophy
C. Left atrial enlargement alone
D. Pericardial effusion
Correct answer: B. Left ventricular hypertrophy
Rationale: Chronic systemic hypertension increases left ventricular afterload, resulting in
compensatory LV hypertrophy. As the ventricle enlarges, the PMI may become displaced
laterally. The supplied material associates longstanding hypertension with an altered PMI.
,Question 5
A 68-year-old patient with hypertension has repeated office readings around 150/92 mmHg but
home readings averaging 124/76 mmHg. What is the most appropriate next step?
A. Immediately add a second antihypertensive
B. Diagnose resistant hypertension
C. Confirm the discrepancy with out-of-office BP monitoring
D. Discontinue antihypertensive treatment
Correct answer: C. Confirm the discrepancy with out-of-office BP monitoring
Rationale: The discrepancy suggests white-coat hypertension. Home or ambulatory BP
monitoring can help distinguish white-coat hypertension from sustained hypertension. Current
diabetes guidance also recommends confirming elevated BP using multiple readings and
recognizes the value of home monitoring.
Question 6
A patient with mitral valve prolapse has palpitations and episodic chest discomfort without
structural complications. Which medication is most appropriate for symptomatic treatment?
A. Metoprolol
B. Digoxin
C. Furosemide
D. Amlodipine
Correct answer: A. Metoprolol
Rationale: Beta-blockers such as metoprolol may reduce adrenergic symptoms, palpitations, and
some chest discomfort associated with uncomplicated mitral valve prolapse. The supplied
material specifically identifies metoprolol as the drug of choice for symptomatic
arrhythmias/chest pain in this setting.
Question 7
A patient with heart failure develops worsening edema after beginning naproxen for arthritis.
What is the best explanation?
, A. Naproxen increases myocardial contractility
B. NSAIDs promote sodium and water retention
C. Naproxen directly causes mitral stenosis
D. NSAIDs increase renal potassium excretion
Correct answer: B. NSAIDs promote sodium and water retention
Rationale: NSAIDs can reduce renal prostaglandin synthesis, impair renal sodium excretion,
increase fluid retention, and worsen hypertension and heart failure. The supplied material
specifically identifies naproxen as a medication that can exacerbate heart failure.
Question 8
Which finding is most characteristic of peripheral arterial disease?
A. Bilateral dependent edema
B. Calf pain with walking relieved by rest
C. Warm legs with bounding pulses
D. Pain that improves when standing
Correct answer: B. Calf pain with walking relieved by rest
Rationale: Intermittent claudication is exertional ischemic muscle pain that improves with
rest. The calf is a classic location when femoropopliteal disease is present. The supplied material
specifically describes lower-leg/calf pain with walking that resolves with rest.
Question 9
Which bedside test is most useful for screening a patient suspected of having peripheral arterial
disease?
A. Allen test
B. Ankle-brachial index
C. Romberg test
D. Weber test
Correct answer: B. Ankle-brachial index
Rationale: The ABI compares ankle systolic pressure with brachial systolic pressure and is a
common noninvasive assessment for PAD. The supplied examination material explicitly
identifies ABI as a screening tool for PAD risk.
