Complete Package Bundle

1. A 62-year-old male with hypertension presents with

substernal chest pressure at rest for 25 minutes. ECG

shows ST depression in leads V3–V6. Troponin is elevated.

What is the most appropriate next step?

A) Aspirin 81 mg and discharge home

B) Exercise stress test within 24 hours

C) Admit for NSTEMI management with heparin and

antiplatelet therapy

D) Prescribe sublingual nitroglycerin and follow up in

clinic

Correct Answer: C

Rationale: Elevated troponin + rest angina + ST

depression = NSTEMI. Requires admission, anticoagulation,

dual antiplatelet therapy, and possible invasive strategy.

2. Which medication has been proven to reduce mortality

in chronic heart failure with reduced ejection fraction

2

,(HFrEF)?

A) Furosemide

B) Metolazone

C) Carvedilol

D) Amlodipine

Correct Answer: C

Rationale: Beta-blockers (carvedilol, bisoprolol,

metoprolol succinate) reduce mortality in HFrEF by

decreasing sympathetic remodeling and sudden cardiac

death.

3. A 78-year-old with atrial fibrillation, CHA₂ DS₂ -

VASc score of 5, and HAS-BLED score of 2 is on warfarin.

INR today is 1.3. What is the best management?

A) Increase warfarin dose and recheck INR in 1 week

B) Start low-molecular-weight heparin bridging and

adjust warfarin

C) Switch to aspirin 81 mg daily

D) Hold warfarin for 3 days
