The nurse is asked to describe what the heart sound S1 represents. What would be the correct response by the nurse?
Closure of mitral and aortic valves
Closure of mitral and tricuspid valves
Closure of pulmonic and tricuspid valves
Closure of pulmonic and aortic valves
Closure of aortic and tricuspid valves
The Correct Answer is B
A. This option incorrectly includes the aortic valve rather than the tricuspid valve in the S1 heart sound.
B. S1 represents the closure of the mitral and tricuspid valves, which occurs at the beginning of ventricular systole and produces the "lub" sound.
C. The pulmonic valve closure is associated with the S2 heart sound, not S1.
D. The closure of the pulmonic and aortic valves occurs in S2, not S1.
E. This combination is incorrect, as S1 is associated with mitral and tricuspid valve closure.
