Question 1
A patient experiences a sudden onset of pain in his lower left leg. He states that the
pain is worse when he walks and he has been experiencing this pain for the past 2
months. Your colleague suggests obtaining leg x-ray imaging to confirm the
diagnosis. Which of the following is NOT a correct treatment option?
A) Elevating the leg
B) Applying warm compresses
C) Smoking cessation
D) Antiplatelet therapy
Correct Answer: B. Applying warm compresses
Rationale: The presentation suggests peripheral arterial disease (PAD) with
intermittent claudication. Treatment includes lifestyle modifications (smoking
cessation, exercise), antiplatelet therapy (aspirin), and leg elevation to improve
venous return. Warm compresses are contraindicated in PAD because they can
increase metabolic demand in ischemic tissue without improving blood flow,
potentially causing tissue damage.
Question 2
A 65-year-old male presents with chest pain that occurs with exertion and is
relieved by rest. The pain is substernal, pressure-like, and radiates to the left arm.
What is the most likely diagnosis?
A) Unstable angina
B) Stable angina
C) Myocardial infarction
D) Pericarditis
Correct Answer: B. Stable angina
,Rationale: Stable angina is characterized by predictable chest pain with exertion
or emotional stress that is relieved by rest or nitroglycerin. The pain is typically
substernal with radiation to the left arm or jaw. Unstable angina occurs at rest or
with minimal exertion. Myocardial infarction presents with prolonged pain not
relieved by rest.
Question 3
Which of the following is the most sensitive diagnostic test for myocardial
infarction?
A) Creatine kinase-MB (CK-MB)
B) Troponin I
C) Myoglobin
D) Lactate dehydrogenase (LDH)
Correct Answer: B. Troponin I
Rationale: Cardiac troponins (troponin I and troponin T) are the most sensitive
and specific biomarkers for myocardial infarction. They rise within 3-4 hours of
myocardial injury and remain elevated for 7-10 days. CK-MB rises within 3-6
hours and returns to normal within 48-72 hours. Myoglobin is less specific.
Question 4
A patient presents with acute onset of severe tearing chest pain radiating to the
back. Blood pressure is 190/110 mmHg in the right arm and 160/90 mmHg in the
left arm. What is the most likely diagnosis?
A) Acute myocardial infarction
B) Aortic dissection
C) Pulmonary embolism
D) Pericarditis
Correct Answer: B. Aortic dissection
Rationale: Aortic dissection presents with acute, severe, tearing chest pain that
radiates to the back. A key finding is a difference in blood pressure between arms
(>20 mmHg systolic). Other findings include new aortic regurgitation murmur and
pulse deficits. Immediate CT angiography is diagnostic.
,Question 5
What is the first-line pharmacologic treatment for stable angina?
A) Beta-blockers
B) Calcium channel blockers
C) Nitrates
D) Aspirin
Correct Answer: A. Beta-blockers
Rationale: Beta-blockers are the first-line treatment for stable angina. They reduce
myocardial oxygen demand by decreasing heart rate and contractility. They are
preferred over calcium channel blockers for initial therapy. Nitrates are used for
acute symptom relief.
Question 6
A patient with heart failure presents with dyspnea on exertion, orthopnea, and
paroxysmal nocturnal dyspnea. What physical finding is most consistent with this
diagnosis?
A) Peripheral edema
B) Jugular venous distension
C) Crackles on lung auscultation
D) All of the above
Correct Answer: D. All of the above
Rationale: Heart failure presents with signs of volume overload including
peripheral edema, jugular venous distension (JVD), and pulmonary crackles due to
pulmonary congestion. Other findings include S3 gallop, hepatojugular reflux, and
ascites.
Question 7
Which medication is contraindicated in patients with severe aortic stenosis?
A) Nitroglycerin
B) Amlodipine
, C) Metoprolol
D) Lisinopril
Correct Answer: A. Nitroglycerin
Rationale: Nitroglycerin and other nitrates are relatively contraindicated in severe
aortic stenosis because they cause vasodilation, which can lead to severe
hypotension and reduced coronary perfusion in patients who are preload-
dependent. Beta-blockers and ACE inhibitors should also be used with caution.
Question 8
A patient presents with palpitations, lightheadedness, and a heart rate of 180 beats
per minute. ECG shows narrow-complex tachycardia with no visible P waves.
What is the most likely diagnosis?
A) Atrial fibrillation
B) Atrial flutter
C) Supraventricular tachycardia
D) Ventricular tachycardia
Correct Answer: C. Supraventricular tachycardia
Rationale: Supraventricular tachycardia (SVT) presents with palpitations,
lightheadedness, and rapid heart rate (typically 150-220 bpm). ECG shows narrow
QRS complex (<0.12 seconds) with no visible P waves. Atrial fibrillation shows an
irregularly irregular rhythm. Ventricular tachycardia has wide QRS complexes.
Question 9
What is the CHA₂DS₂-VASc score used for?
A) Predicting mortality in heart failure
B) Assessing stroke risk in atrial fibrillation
C) Evaluating bleeding risk in anticoagulated patients
D) Predicting cardiovascular events
Correct Answer: B. Assessing stroke risk in atrial fibrillation
Rationale: The CHA₂DS₂-VASc score is used to assess stroke risk in patients with
atrial fibrillation. It includes Congestive heart failure, Hypertension, Age ≥75 (2
