Cardiovascular Disorders
Question 1
A 62-year-old man presents with crushing substernal chest pain radiating to his left arm for 45
minutes. What is the priority diagnosis?
A. Stable angina
B. Gastroesophageal reflux disease
C. Acute myocardial infarction
D. Costochondritis
Correct Answer: C. Acute myocardial infarction
Rationale:
Prolonged crushing chest pain lasting more than 20–30 minutes with radiation to the left arm
strongly suggests an acute myocardial infarction (AMI). Stable angina typically resolves with
,rest or nitroglycerin. GERD causes burning discomfort rather than pressure-like pain, while
costochondritis is reproducible with chest wall palpation.
Question 2
Which medication should generally be prescribed first-line for uncomplicated hypertension in
many adults?
A. Aspirin
B. Thiazide diuretic
C. Digoxin
D. Warfarin
Correct Answer: B. Thiazide diuretic
Rationale:
Thiazide diuretics are commonly recommended as first-line therapy for uncomplicated
hypertension, depending on patient-specific factors. Aspirin does not treat hypertension. Digoxin
is used primarily for certain arrhythmias and heart failure. Warfarin is an anticoagulant.
Question 3
A patient with atrial fibrillation is at increased risk for which complication?
A. Pulmonary fibrosis
B. Stroke
C. Peptic ulcer disease
D. Hyperthyroidism
Correct Answer: B. Stroke
Rationale:
Atrial fibrillation promotes blood stasis within the atria, increasing the risk of thrombus
formation and embolic stroke. Risk assessment tools help determine the need for anticoagulation.
Question 4
Which heart sound is commonly associated with heart failure caused by volume overload?
,A. S1
B. S2
C. S3
D. Opening snap
Correct Answer: C. S3
Rationale:
An S3 gallop often indicates increased ventricular filling pressures and volume overload,
commonly seen in systolic heart failure.
Question 5
A patient with stable angina reports chest discomfort during exercise that resolves with rest.
What is the underlying mechanism?
A. Complete coronary artery occlusion
B. Transient imbalance between myocardial oxygen supply and demand
C. Aortic dissection
D. Pulmonary embolism
Correct Answer: B.
Rationale:
Stable angina occurs when myocardial oxygen demand exceeds supply because of fixed coronary
artery narrowing. Symptoms are predictable and relieved by rest.
Question 6
Which laboratory marker rises earliest after myocardial injury?
A. Troponin
B. LDL cholesterol
C. Hemoglobin
D. BNP
Correct Answer: A. Troponin
, Rationale:
Cardiac troponins are highly sensitive and specific markers of myocardial injury and become
elevated within hours after infarction.
Question 7
Which lifestyle modification produces one of the greatest reductions in blood pressure?
A. Increased sodium intake
B. Regular aerobic exercise
C. Smoking
D. Sedentary lifestyle
Correct Answer: B.
Rationale:
Regular aerobic exercise significantly lowers blood pressure and reduces overall cardiovascular
risk.
Question 8
A patient with heart failure develops bilateral lower extremity edema. What is the primary cause?
A. Increased venous pressure
B. Hyperthyroidism
C. Dehydration
D. Hypoglycemia
Correct Answer: A.
Rationale:
Right-sided heart failure leads to systemic venous congestion, causing peripheral edema.
Question 9
Which medication class reduces mortality in patients with heart failure with reduced ejection
fraction?
A. ACE inhibitors
