C) It is less sensitive to operator skill
D) It replaces the need for Doppler studies
Answer: B
Explanation: 3D echocardiography offers enhanced spatial resolution and more precise anatomic
visualization than 2D imaging.
Question 14: Which of the following best describes the mechanics of normal cardiac physiology?
A) Systolic contraction and diastolic relaxation
B) Only systolic function is important
C) Only diastolic function is measured
D) Atrial contraction is insignificant
Answer: A
Explanation: The heart’s normal function depends on coordinated systolic contraction and diastolic
relaxation for effective blood flow.

A) The force of each contraction
B) The total volume of blood pumped per minute
C) The duration of systole
D) The resistance of peripheral vessels
