Answer 1

The presence of an additional sound immediately following S2 in clients with CHF is called a third heart sound, S3, which can result from various factors. S3 may indicate congestive heart failure.

Step-by-step explanation:

When listening to heart sounds, the nurse expects to hear S1 and S2. The presence of an additional sound immediately following S2 in clients with CHF is called a third heart sound, S3, which can result from blood flowing into the atria, sloshing back and forth in the ventricle, or tensing of the chordae tendineae. S3 may be heard in youth, some athletes, and pregnant women, but if it is heard later in life, it may indicate congestive heart failure.
