Question

a. ventricular systole
b. ventricular diastole
c. atrial systole

if you hear an abnormal second heart sound, which valves could be affected?
select all that apply.
a. right av valve
b. pulmonary semilunar valve
c. left av valve
d. aortic semilunar valve

in a patient with normal heart sounds which of the following would you hear in the fifth left i

Explanation:

The second heart sound (S₂) is produced by the closure of the semilunar valves (pulmonary and aortic) during ventricular diastole. So, abnormal S₂ relates to pulmonary semilunar (B) and aortic semilunar (D) valves. The AV valves (A, C) are involved in the first heart sound (S₁), so they don't affect S₂. Thus, B and D are correct.

Answer:

B. Pulmonary semilunar valve, D. Aortic semilunar valve
