Question 1
A 62-year-old male with a history of hypertension and type 2 diabetes presents
with complaints of substernal chest pressure that occurs with exertion and is
relieved by rest. He describes the pain as a "heavy pressure" that radiates to his left
shoulder. His vital signs are BP 148/90, HR 88, RR 18. An ECG shows no acute
ST-segment changes. What is the most appropriate initial diagnostic test for this
patient?
A. Exercise stress test
B. Coronary angiography
C. Serum cardiac biomarkers
D. Chest X-ray
Correct Answer: A
Rationale: This patient has stable angina — exertional chest pressure relieved by
rest. With a normal ECG and no acute changes, the most appropriate initial
diagnostic test is an exercise stress test (or stress echocardiography) to evaluate
for inducible ischemia. Coronary angiography is reserved for patients with high-
risk features or positive stress tests. Cardiac biomarkers (troponin) are indicated for
acute coronary syndrome, not stable angina. Chest X-ray is not diagnostic for
coronary artery disease.
Question 2
A 55-year-old female presents with progressive shortness of breath on exertion,
orthopnea, and lower extremity edema. She has a history of hypertension and
coronary artery disease. On examination, you note jugular venous distension, S3
gallop, and crackles at both lung bases. Her ejection fraction on recent
echocardiography was 35%. Which of the following medication classes has been
,shown to reduce mortality in heart failure with reduced ejection fraction
(HFrEF)?
A. Calcium channel blockers
B. Beta-blockers
C. Alpha-blockers
D. Non-dihydropyridine calcium channel blockers
Correct Answer: B
Rationale: Beta-blockers (carvedilol, metoprolol succinate, bisoprolol) have been
shown to reduce mortality in patients with HFrEF and are part of guideline-
directed medical therapy. Calcium channel blockers (especially non-
dihydropyridine) have negative inotropic effects and are contraindicated in HFrEF.
Alpha-blockers are not first-line for HFrEF.
Question 3
A 68-year-old male presents with a systolic ejection murmur best heard at the right
upper sternal border that radiates to the carotid arteries. His carotid upstrokes are
delayed and diminished. He reports exertional dyspnea and near-syncope with
activity. What is the most likely diagnosis?
A. Aortic stenosis
B. Aortic regurgitation
C. Mitral stenosis
D. Hypertrophic cardiomyopathy
Correct Answer: A
Rationale: This patient has classic signs of aortic stenosis: systolic ejection
murmur at the right upper sternal border radiating to the carotids, delayed carotid
upstrokes (pulsus parvus et tardus), and symptoms of exertional dyspnea and near-
syncope. Aortic regurgitation presents with a diastolic blowing murmur. Mitral
stenosis presents with a diastolic rumble. Hypertrophic cardiomyopathy presents
with a systolic murmur that decreases with squatting.
Question 4
,A 72-year-old female with a history of atrial fibrillation and chronic kidney disease
(CrCl 28 mL/min) presents for anticoagulation management. Which of the
following anticoagulants is most appropriate for stroke prevention in this patient?
A. Warfarin
B. Apixaban
C. Dabigatran
D. Rivaroxaban
Correct Answer: B
Rationale: In a patient with atrial fibrillation and chronic kidney disease (CrCl
< 30 mL/min) , apixaban is the most appropriate DOAC as it has the least renal
clearance and has been studied in patients with CrCl as low as 25 mL/min.
Warfarin is an option but requires INR monitoring. Dabigatran and rivaroxaban are
contraindicated or require dose adjustment in severe renal impairment (CrCl < 30
mL/min).
Question 5
A 58-year-old male presents with a 2-hour history of crushing substernal chest pain
radiating to his left arm. He is diaphoretic and nauseated. ECG shows ST-segment
elevation in leads V1-V4. His BP is 100/70 mmHg. What is the most appropriate
immediate management?
A. Aspirin 324 mg chewed and primary percutaneous coronary intervention
(PCI)
B. Aspirin 324 mg chewed and thrombolytic therapy
C. Morphine sulfate 4 mg IV and oxygen
D. Sublingual nitroglycerin and morphine
Correct Answer: A
Rationale: This patient is experiencing an acute STEMI (ST elevation in V1-V4,
anterior wall MI). The most appropriate immediate management is aspirin 324 mg
chewed and primary PCI if available within 90 minutes. Thrombolytic therapy is
appropriate if PCI is not available within 120 minutes. Nitroglycerin is relatively
contraindicated with BP 100/70 (SBP < 110). Morphine and oxygen are supportive
but not definitive.
, Question 6
A 45-year-old female presents with palpitations and lightheadedness. Her ECG
shows a narrow-complex tachycardia at 170 bpm. She is hemodynamically stable
with BP 128/82. What is the most appropriate first-line management?
A. Synchronized cardioversion
B. Adenosine 6 mg IV rapid push
C. Verapamil 5 mg IV push
D. Amiodarone 150 mg IV push
Correct Answer: B
Rationale: This patient has narrow-complex tachycardia (likely supraventricular
tachycardia, SVT) and is hemodynamically stable. The first-line treatment
is adenosine 6 mg IV rapid push followed by a saline flush. Adenosine blocks the
AV node and terminates reentrant tachycardias. Synchronized cardioversion is for
unstable patients. Verapamil is a second-line agent but not first-line. Amiodarone
is not first-line for narrow-complex tachycardia.
Question 7
A 65-year-old male with a history of hypertension is found to have a blood
pressure of 168/96 mmHg on two separate occasions. He has no target organ
damage. Which of the following is the most appropriate initial antihypertensive
medication?
A. Hydrochlorothiazide
B. Metoprolol
C. Lisinopril
D. Amlodipine
Correct Answer: C
Rationale: For a patient with hypertension without compelling indications,
ACE inhibitors (lisinopril), ARBs, calcium channel blockers, or thiazide diuretics
are all acceptable first-line options. Lisinopril (ACE inhibitor) is an appropriate
choice. HCTZ and amlodipine are also acceptable, but ACE inhibitors are often
