100 PRACTICE QUESTIONS WITH ANSWERS AND
RATIONALES
2026–2027 TESTING CYCLE
SECTION 1: CARDIOVASCULAR DISORDERS (Questions 1–10)
Question 1: A 55-year-old male with a 30-pack-year smoking history presents with exertional
chest pressure relieved by rest. He has hypertension and hyperlipidemia. What is the most likely
diagnosis?
Answer: Stable angina pectoris.
Rationale: Stable angina is characterized by predictable chest pain triggered by exertion or
emotional stress and relieved by rest or nitroglycerin. The patient has multiple risk factors
(smoking, hypertension, hyperlipidemia). Unstable angina occurs at rest or with minimal
exertion. Prinzmetal's angina is variant angina caused by coronary artery spasm. Aortic stenosis
presents with syncope, angina, and dyspnea.
,Question 2: A 72-year-old female presents with progressive shortness of breath, orthopnea, and
bilateral lower extremity edema. On examination, she has jugular venous distention and crackles
in the lung bases. What is the most appropriate initial diagnostic test?
Answer: Echocardiogram.
Rationale: Echocardiography is the gold standard for evaluating heart failure, assessing left
ventricular ejection fraction, valvular function, and chamber sizes. BNP or NT-proBNP is a
useful biomarker but does not identify the underlying structural cause. Chest X-ray can show
cardiomegaly and pulmonary congestion but is less specific. ECG may show ischemia or
arrhythmias but is not diagnostic for heart failure.
Question 3: A 68-year-old male with a history of hypertension presents with sudden onset of
severe, tearing chest pain radiating to the back. His blood pressure is 190/110 mmHg. What is
the most likely diagnosis?
Answer: Aortic dissection.
Rationale: Aortic dissection presents with sudden, severe, tearing chest pain that may radiate to
the back. Hypertension is a major risk factor. The pain is typically maximal at onset, unlike
myocardial infarction, which may be more gradual. Pulmonary embolism presents with pleuritic
chest pain and dyspnea. Pericarditis presents with sharp, positional pain relieved by sitting
forward.
,Question 4: A 45-year-old female presents with palpitations, anxiety, heat intolerance, and
weight loss despite increased appetite. She has a fine tremor and lid lag on examination. What
laboratory test is most useful for diagnosis?
Answer: TSH and free T4.
Rationale: Hyperthyroidism is diagnosed with suppressed TSH and elevated free T4 (or T3). The
classic symptoms include palpitations, anxiety, heat intolerance, weight loss, tremor, and lid lag.
TSH alone is not sufficient; free T4 is necessary for confirmation. T3 and T4 levels without TSH
do not provide the complete picture.
Question 5: A 50-year-old male with diabetes and hypertension presents with a sudden onset of
severe headache, nausea, and visual changes. His blood pressure is 220/130 mmHg. What is the
most appropriate initial management?
Answer: Hospitalize for hypertensive emergency and initiate IV antihypertensive therapy.
Rationale: Hypertensive emergency is defined as severe hypertension with acute target organ
damage (neurologic symptoms, visual changes). This patient requires hospitalization and IV
antihypertensive therapy (e.g., labetalol, nicardipine, sodium nitroprusside). Oral medications
are not appropriate for acute hypertensive emergencies.
, Question 6: A 60-year-old female with a history of atrial fibrillation is on warfarin for stroke
prevention. Her INR is 4.5. She has no signs of bleeding. What is the most appropriate action?
Answer: Hold warfarin and monitor INR.
Rationale: For an asymptomatic patient with an INR between 4.0 and 5.0, the recommended
approach is to hold warfarin and monitor INR. Vitamin K is typically reserved for INR >5.0 or
active bleeding. Protamine sulfate is used for heparin reversal. For INR 5.0–9.0, holding
warfarin may be sufficient; vitamin K may be considered for higher INR.
Question 7: A 40-year-old male presents with intermittent claudication in his calves after
walking one block. He has a history of smoking and diabetes. Pulses are diminished in the lower
extremities. What is the most appropriate initial diagnostic test?
Answer: Ankle-brachial index (ABI).
Rationale: ABI is the initial, non-invasive screening test for peripheral arterial disease. An ABI
<0.90 is diagnostic. Doppler ultrasound, angiography, and CT angiography are additional tests
but are not the initial screening tests. ABI is simple, quick, and cost-effective.
Question 8: A 55-year-old female presents with chest pain that is sharp, positional (worse when
lying flat), and relieved by sitting forward. She reports a recent upper respiratory infection. What
is the most likely diagnosis?
