1. Which cardiac structure is responsible for preventing backflow of
blood from the left ventricle into the left atrium?
A. Tricuspid valve
B. Pulmonic valve
C. Mitral valve
D. Aortic valve
Answer: C
The mitral valve closes during systole to prevent regurgitation into
the left atrium.
2. The primary acoustic window used to assess left ventricular
function is the:
A. Suprasternal window
B. Subcostal window
C. Apical window
D. Right parasternal window
Answer: C
The apical window provides optimal visualization of ventricular
chambers and motion.
3. Which ECG component corresponds to ventricular depolarization?
A. P wave
, B. PR interval
C. QRS complex
D. T wave
Answer: C
The QRS complex represents ventricular depolarization.
4. In echocardiography, increasing the transducer frequency will
result in:
A. Greater penetration
B. Reduced resolution
C. Improved axial resolution
D. Increased Doppler shift error
Answer: C
Higher frequency improves resolution but decreases penetration.
5. The left ventricular ejection fraction is best calculated using which
method?
A. M-mode Teichholz
B. Simpson’s biplane method
C. Fractional shortening
D. Pressure half-time
Answer: B
Simpson’s method is the recommended standard for EF
calculation.
6. Which view best demonstrates the interventricular septum and
posterior wall motion?
A. Parasternal long-axis
B. Apical four-chamber
C. Subcostal four-chamber
, D. Suprasternal long-axis
Answer: A
Parasternal long-axis allows assessment of septal and posterior
wall motion.
7. Color Doppler aliasing occurs when:
A. Gain is too low
B. Velocity exceeds the Nyquist limit
C. Wall filters are increased
D. Pulse repetition frequency is too high
Answer: B
Aliasing occurs when blood velocity exceeds the Nyquist limit.
8. Which valve is normally visualized between the right atrium and
right ventricle?
A. Mitral
B. Aortic
C. Pulmonic
D. Tricuspid
Answer: D
The tricuspid valve separates the right atrium and ventricle.
9. The normal adult left ventricular ejection fraction range is
approximately:
A. 30–45%
B. 40–55%
C. 55–70%
D. 70–85%
Answer: C
A normal EF is generally considered 55–70%.
