CCTN MULTIPLE-CHOICE EXAM QUESTIONS AND
ANSWERS UPDATED 2026




SECTION 1: CARDIOVASCULAR ASSESSMENT & HEMODYNAMICS

Question 1

Which parameter best reflects left ventricular preload?

A. Systemic vascular resistance
B. Pulmonary artery wedge pressure
C. Cardiac output
D. Mean arterial pressure

Correct Answer: B
Rationale: Pulmonary artery wedge pressure estimates left ventricular end-diastolic pressure
and preload.



Question 2

A cardiac output of 3.5 L/min is considered:

A. Normal
B. Elevated
C. Borderline low
D. Severely high

Correct Answer: C
Rationale: Normal cardiac output is 4–8 L/min.



Question 3

Which value indicates adequate tissue perfusion?

, A. MAP 55 mmHg
B. MAP 65 mmHg
C. MAP 50 mmHg
D. MAP 45 mmHg

Correct Answer: B
Rationale: A MAP ≥65 mmHg is required to maintain organ perfusion.



Question 4

An increase in afterload will have what effect on cardiac output?

A. Increase cardiac output
B. No effect
C. Decrease cardiac output
D. Increase preload

Correct Answer: C
Rationale: Increased afterload makes ventricular ejection more difficult, lowering output.



Question 5

Which medication primarily reduces afterload?

A. Dopamine
B. Norepinephrine
C. Nitroprusside
D. Digoxin

Correct Answer: C
Rationale: Nitroprusside is a potent arterial vasodilator.



SECTION 2: ACUTE CORONARY SYNDROME & ECG INTERPRETATION

Question 6

ST-segment elevation indicates:

A. Myocardial ischemia
B. Myocardial infarction
