Verified
A nurse auscultates heart sounds. When the nurse hears S?, which valves is the nurse hearing close?
A) Aortic and mitral
B) Mitral and tricuspid
C) Aortic and pulmonic
D) Mitral and pulmonic
Heart Sounds
The noises generated by the beating heart and the resultant flow of blood through it.
Tricuspid
Relating to the valve between the right atrium and right ventricle of the heart, consisting of three cusps or flaps that prevent blood from flowing backwards.
Pulmonic

Final Answer :
C
Explanation :
As the ventricles empty, the ventricular pressures decrease, allowing closure of the aortic and pulmonic valves, producing the second heart sound, S?. The mitral and tricuspid produce the first heart sound, S?. The aortic and mitral do not close at the same time. The mitral and pulmonic do not close at the same time.
