1. Which of the following are common risk factors for
coronary artery disease (CAD)?
A. Hypertension
B. Smoking
C. Diabetes mellitus
D. Low LDL cholesterol
Answer: A, B, C
Rationale: Hypertension, smoking, and diabetes increase CAD
risk by promoting atherosclerosis. Low LDL is protective.
2. A patient presents with crushing chest pain radiating to the
left arm. Which conditions should be considered?
A. Myocardial infarction (MI)
B. Pulmonary embolism (PE)
C. Gastroesophageal reflux disease (GERD)
D. Panic attack
Answer: A, B, C, D
Rationale: Chest pain can have cardiac, pulmonary,
gastrointestinal, or psychological causes; MI is most critical to
rule out first.
,3. Which ECG changes are commonly seen in an acute
myocardial infarction?
A. ST-segment elevation
B. T-wave inversion
C. Q waves
D. Prolonged PR interval
Answer: A, B, C
Rationale: ST elevation, T-wave inversion, and Q waves indicate
myocardial injury/necrosis; PR interval is usually unaffected.
4. Which of the following are symptoms of heart failure?
A. Dyspnea on exertion
B. Peripheral edema
C. Orthopnea
D. Bradycardia
Answer: A, B, C
Rationale: Heart failure presents with fluid overload and
dyspnea. Bradycardia is not a primary symptom.
5. Common causes of left-sided heart failure include:
A. Hypertension
B. Myocardial infarction
C. Aortic stenosis
D. Pulmonary embolism
Answer: A, B, C
,Rationale: Left-sided HF arises from conditions that impair left
ventricular function. PE primarily causes right-sided failure.
6. Which are the classic signs of right-sided heart failure?
A. Jugular venous distension
B. Hepatomegaly
C. Ascites
D. Pulmonary crackles
Answer: A, B, C
Rationale: Right-sided HF leads to systemic venous congestion;
pulmonary crackles are more typical of left-sided HF.
7. Indications for immediate defibrillation include:
A. Ventricular fibrillation (VF)
B. Pulseless ventricular tachycardia (VT)
C. Asystole
D. Pulseless electrical activity (PEA)
Answer: A, B
Rationale: VF and pulseless VT are shockable rhythms; asystole
and PEA require CPR and medications, not defibrillation.
8. Common medications used in ACS management include:
A. Aspirin
B. Nitroglycerin
C. Beta-blockers
, D. Antibiotics
Answer: A, B, C
Rationale: Aspirin, nitroglycerin, and beta-blockers reduce
myocardial damage. Antibiotics are not indicated unless
infection is present.
9. Which are typical signs of cardiogenic shock?
A. Hypotension
B. Cool, clammy skin
C. Tachycardia
D. Bradycardia
Answer: A, B, C
Rationale: Cardiogenic shock presents with low perfusion and
compensatory tachycardia. Bradycardia is not typical.
10. Which cardiac enzymes indicate myocardial infarction?
A. Troponin I/T
B. CK-MB
C. Myoglobin
D. ALT
Answer: A, B, C
Rationale: Troponins and CK-MB are specific markers of cardiac
injury; ALT is a liver enzyme.
