Question 1:
A 58-year-old man with HFrEF (EF 30%) presents with dyspnea. BP 88/54, HR 112, JVP
elevated, cool extremities, lactate 4.2. He has been nonadherent to furosemide. Which
best initial therapy?
A. IV furosemide alone
B. Dobutamine infusion
C. Norepinephrine plus diuresis
D. Oral sacubitril-valsartan uptitration
Correct: C. Rationale : cold/wet profile with hypotension and hypoperfusion;
norepinephrine to maintain MAP plus diuresis.

COMPREHENSIVE EXAM PACK 2026-2027: 150 HIGH-YIELD CASE-BASED MCQS WITH
RATIONALE S FOR HEALTH SCIENCES
1. A 58-year-old man with heart failure with reduced ejection fraction (EF 30%) presents
with worsening dyspnea. BP is 88/54 mmHg, HR 112/min, JVP elevated, extremities cool,
and lactate 4.2 mmol/L. He has been nonadherent to furosemide. Which is the most
appropriate initial therapy?
A. Intravenous furosemide alone
B. Dobutamine infusion
C. Norepinephrine infusion plus diuresis
D. Oral sacubitril-valsartan uptitration
Correct Answer : C
Rationale : The patient has a cold-and-wet profile with hypotension and hypoperfusion;
norepinephrine supports MAP while decongestion is achieved.
2. A 67-year-old woman with atrial fibrillation is started on apixaban. Which laboratory
parameter is most important to assess before initiation?
A. International normalized ratio
B. Serum creatinine and calculated creatinine clearance
C. Platelet count only
D. Activated partial thromboplastin time
Correct Answer : B
,Rationale : Apixaban is renally cleared; dose reduction depends on creatinine
clearance, age, and weight.
3. A 45-year-old man presents with tearing chest pain radiating to the back. BP is 180/100
mmHg in the right arm and 140/80 mmHg in the left arm. Chest radiograph shows a
widened mediastinum. Which is the most urgent diagnostic study?
A. Transthoracic echocardiography
B. D-dimer
C. CT angiography of the aorta
D. Exercise stress testing
Correct Answer : C
Rationale : Suspected aortic dissection requires urgent CT angiography for
confirmation and classification.
4. A 72-year-old woman with severe aortic stenosis develops syncope during exertion.
Which pathophysiologic mechanism best explains exertional syncope?
A. Fixed left ventricular outflow obstruction limiting cardiac output increase
B. Acute mitral regurgitation
C. Loss of atrial kick
D. Reflex bradycardia from carotid sinus hypersensitivity
Correct Answer : A
Rationale : In severe aortic stenosis, fixed outflow obstruction prevents adequate
augmentation of cardiac output during exertion, causing syncope.
5. A 34-year-old man with hypertension and hypokalemia is found to have an aldosterone-
to-renin ratio of 32. Which confirmatory test is most appropriate?
A. Overnight dexamethasone suppression test
, B. Saline infusion test
C. Plasma metanephrines
D. Renal artery Doppler
Correct Answer : B
Rationale : Primary aldosteronism is confirmed with saline loading, which fails to
suppress aldosterone in autonomous secretion.
6. A 60-year-old man with chronic stable angina is prescribed metoprolol. Which effect
most directly reduces myocardial oxygen demand?
A. Decreased heart rate and contractility
B. Coronary vasodilation
C. Reduced preload
D. Increased collateral flow
Correct Answer : A
Rationale : Beta-blockers reduce heart rate and contractility, lowering myocardial
oxygen consumption.
7. A 28-year-old woman with palpitations has a narrow-complex tachycardia at 180/min.
She is hemodynamically stable. Vagal maneuvers fail. Which is the next best intervention?
A. Synchronized cardioversion
B. Adenosine 6 mg IV push
C. Amiodarone infusion
D. Diltiazem oral
Correct Answer : B
Rationale : Adenosine is first-line for stable narrow-complex supraventricular
tachycardia after vagal maneuvers fail.
