1. Which symptom is considered the hallmark presentation of stable angina?
A. Chest pain occurring at rest for more than 30 minutes
B. Substernal chest discomfort precipitated by exertion and relieved by rest or nitroglycerin
C. Sharp pleuritic chest pain that worsens with inspiration
D. Sudden tearing chest pain radiating to the back
Answer: B
Solution: Stable angina results from predictable myocardial ischemia during increased oxygen
demand. Symptoms are typically relieved by rest or nitroglycerin within a few minutes.
2. Which risk factor for coronary artery disease is nonmodifiable?
A. Smoking
B. Hypertension
C. Age
D. Obesity
Answer: C
Solution: Age is a nonmodifiable risk factor. Smoking, hypertension, obesity, and dyslipidemia
are modifiable.
3. Which laboratory biomarker is most specific for diagnosing acute myocardial infarction?
A. Creatine kinase
B. Troponin I or Troponin T
C. Myoglobin
D. Lactate dehydrogenase
Answer: B
,Solution: Cardiac troponins are the preferred biomarkers because of their high sensitivity and
specificity for myocardial injury.
4. Which heart sound is commonly associated with heart failure?
A. S1 splitting
B. S3 gallop
C. Pericardial friction rub
D. Opening snap
Answer: B
Solution: An S3 gallop often indicates volume overload and is commonly associated with left
ventricular dysfunction and heart failure.
5. Which medication class is considered first-line therapy for hypertension in many adults?
A. ACE inhibitors
B. Antihistamines
C. Proton pump inhibitors
D. Opioids
Answer: A
Solution: ACE inhibitors are among the recommended first-line antihypertensive agents,
depending on patient characteristics.
6. Which physical examination finding is most suggestive of left-sided heart failure?
A. Crackles at the lung bases
B. Hepatomegaly only
C. Ascites only
D. Splenomegaly
Answer: A
Solution: Pulmonary congestion causes bibasilar crackles due to fluid accumulation in the lungs.
7. Which symptom is most characteristic of right-sided heart failure?
, A. Peripheral edema and jugular venous distention
B. Hemoptysis only
C. Epigastric pain only
D. Persistent hiccups
Answer: A
Solution: Right-sided heart failure leads to systemic venous congestion, producing peripheral
edema and jugular venous distention.
8. Which diagnostic test confirms atrial fibrillation?
A. Electrocardiogram (ECG)
B. Chest X-ray only
C. Pulmonary function testing
D. Arterial blood gas
Answer: A
Solution: ECG demonstrates an irregularly irregular rhythm with absent P waves.
9. Which medication is commonly prescribed to reduce stroke risk in atrial fibrillation?
A. Anticoagulants
B. Antacids
C. Bronchodilators
D. Antihistamines
Answer: A
Solution: Oral anticoagulants significantly reduce thromboembolic risk in eligible patients with
atrial fibrillation.
10. Which symptom is most concerning for acute pulmonary embolism?
A. Sudden dyspnea with pleuritic chest pain
B. Chronic productive cough for years
C. Mild nasal congestion
D. Gradual onset sore throat
Answer: A
