Extract:


Question 1 of 5

The nurse is listening to the heart sounds of a client. The nurse recognizes that the S2:

Correct Answer: D

Rationale: The correct answer is D: Is caused by the closure of the semilunar valves. S2 is the second heart sound heard during the cardiac cycle and is caused by the closure of the aortic and pulmonic (semilunar) valves at the end of systole. This closure prevents blood from flowing back into the ventricles. Understanding the timing and mechanism of S2 is crucial in assessing cardiac function.

Choices A, B, and C are incorrect because S2 does not indicate the beginning of diastole, coincide with the carotid artery pulse, or is louder than S1. It is important to differentiate the sounds of the heart to accurately assess the patient's condition.
