SECTION 1: ASSESSMENT, DIAGNOSIS & CLINICAL REASONING Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A 62-year-old male presents with progressive dyspnea on exertion, orthopnea, and bilateral
lower extremity edema. Physical exam reveals jugular venous distension at 8 cm H₂O, an S3
gallop, and hepatomegaly. Echocardiogram shows an ejection fraction of 25% with global
hypokinesis. Which diagnostic finding is most consistent with this patient's underlying
pathophysiology?
A. Elevated B-type natriuretic peptide (BNP) with reduced cardiac output
B. Normal pulmonary capillary wedge pressure with preserved ventricular compliance
C. Increased ejection fraction on repeat echocardiogram after preload reduction
D. Decreased left ventricular end-diastolic volume with compensatory tachycardia ✓
CORRECT
Correct Answer: D
Rationale: In systolic heart failure with reduced ejection fraction, the left ventricle dilates and
end-diastolic volume increases due to remodeling, not decreases; the examiner is testing
whether the APRN recognizes that decreased end-diastolic volume contradicts the
compensatory Frank-Starling mechanism and volume overload state. The most tempting
wrong answer, elevated BNP with reduced cardiac output, is actually consistent with the
diagnosis rather than inconsistent. Remember that exam questions testing pathophysiologic
consistency require you to identify the finding that does NOT fit the clinical picture.
Question 2 of 50
A 28-year-old female presents with a 6-week history of fatigue, low-grade fever, and migratory
arthralgias involving her knees, wrists, and elbows. She has a new holosystolic murmur at the
apex and multiple painless erythematous lesions on her palms. Blood cultures are pending.
,Which clinical finding would most strongly support the diagnosis of infective endocarditis in
this patient?
A. Janeway lesions with negative blood cultures and normal echocardiogram
B. Osler nodes with positive blood cultures and vegetation on transthoracic echo ✓ CORRECT
C. Roth spots with leukocytosis and sterile blood cultures
D. Splinter hemorrhages with elevated erythrocyte sedimentation rate and normal valve
anatomy
Correct Answer: B
Rationale: Osler nodes represent immune-complex deposition in infective endocarditis and,
when combined with positive blood cultures and echocardiographic evidence of vegetation,
fulfill major Duke criteria for definitive diagnosis. Janeway lesions are non-tender septic
emboli but negative blood cultures and normal echocardiogram would not support
endocarditis, making option A a classic distractor. On the APRN exam, always look for the
combination of major Duke criteria: positive blood cultures plus vegetation evidence.
Question 3 of 50
A 45-year-old male with a 20-pack-year smoking history presents with a persistent cough,
hemoptysis, and a 15-pound weight loss over three months. Chest CT reveals a 4 cm
spiculated mass in the left upper lobe with mediastinal lymphadenopathy. Bronchoscopy with
biopsy confirms adenocarcinoma. PET-CT shows no distant metastasis. According to the
TNM staging system, which factor most significantly determines this patient's stage?
A. The presence of hemoptysis as a symptom of central airway involvement
B. The size of the primary tumor and extent of regional lymph node involvement ✓ CORRECT
C. The histologic subtype being adenocarcinoma rather than squamous cell carcinoma
D. The patient's smoking history and age-adjusted performance status
Correct Answer: B
Rationale: In the TNM staging system for non-small cell lung cancer, the T (tumor
size/extent) and N (regional node involvement) components are the primary determinants of
stage when no distant metastasis is present; this patient's 4 cm mass and mediastinal nodes
would place him in at least stage IIIA. Hemoptysis is a clinical symptom but does not factor
into the anatomic staging system, which is a common misconception among test-takers.
Focus on the objective radiographic and pathologic findings rather than symptoms when
answering staging questions.
Question 4 of 50
A 38-year-old female presents with episodic severe headaches accompanied by palpitations,
diaphoresis, and anxiety. During an episode, her blood pressure is 220/130 mmHg. Urine
catecholamines and metanephrines are elevated threefold above the upper limit of normal.
, CT abdomen reveals a 5 cm right adrenal mass. Which preoperative management strategy is
most appropriate before adrenalectomy?
A. Initiate phenoxybenzamine 10 mg twice daily for 7-14 days followed by liberal salt and fluid
intake ✓ CORRECT
B. Begin propranolol 40 mg twice daily immediately to control tachycardia and hypertension
C. Administer intravenous normal saline bolus without alpha-blockade to expand
intravascular volume
D. Start metyrosine alone for 2 weeks preoperatively without concurrent alpha-adrenergic
blockade
Correct Answer: A
Rationale: Alpha-blockade with phenoxybenzamine is the cornerstone of preoperative
preparation for pheochromocytoma, followed by volume expansion through salt and fluid
loading to prevent intraoperative hypotension after tumor removal. Starting non-selective
beta-blockade like propranolol without prior alpha-blockade is dangerous and can precipitate
unopposed alpha-mediated vasoconstriction and hypertensive crisis. The 7-14 day
alpha-blockade protocol is specifically emphasized in endocrine surgical guidelines and is a
high-yield APRN exam concept.
Question 5 of 50
A 55-year-old African American male with type 2 diabetes mellitus and hypertension presents
for a routine follow-up. His home blood pressure log shows readings consistently between
138-145/82-88 mmHg. He currently takes lisinopril 20 mg daily. His serum creatinine is 1.1
mg/dL, potassium 4.2 mEq/L, and urine albumin-to-creatinine ratio is 45 mg/g. Which
adjustment to his antihypertensive regimen is most appropriate?
A. Add hydrochlorothiazide 25 mg daily to achieve faster blood pressure control
B. Increase lisinopril to 40 mg daily and reassess in 4 weeks ✓ CORRECT
C. Switch to amlodipine 10 mg daily as first-line monotherapy
D. Add losartan 50 mg daily for dual renin-angiotensin system blockade
Correct Answer: B
Rationale: For patients with diabetes and albuminuria (urine ACR 30-300 mg/g), ACE inhibitors
should be titrated to the maximum tolerated dose to optimize renal protection and blood
pressure control; increasing lisinopril to 40 mg is guideline-concordant before adding a
second agent. Dual renin-angiotensin system blockade with ACE inhibitor plus ARB is
explicitly contraindicated due to increased risk of hyperkalemia and acute kidney injury.
Thiazide diuretics are reasonable add-on agents but should follow optimization of the ACE
inhibitor dose.
