A nurse is performing a cardiac assessment on a client and auscultates an S3 sound. The nurse should recognize that this sound represents which of the following heart conditions?

Closure of pulmonic valve

Closure of the mitral valve

Ventricular gallop

Atrial gallop

Answer and Explanation

The Correct Answer is C

Ventricular gallop is another name for the S3 sound, which is a low-pitched sound heard at the end of diastole, just after the S2 sound. It is caused by the rapid filling of the ventricles and the vibration of the ventricular walls.

Closure of the pulmonic valve is one of the components of the S2 sound, which is a high-pitched sound heard at the end of the systole, just before the S1 sound. It is caused by the closure of the semilunar valves (pulmonic and aortic).

Closure of the mitral valve is one of the components of the S1 sound, which is a high-pitched sound heard at the beginning of systole, just after the S2 sound. It is caused by the closure of the atrioventricular valves (mitral and tricuspid).

d. Atrial gallop is another name for the S4 sound, which is a low-pitched sound heard at the end of diastole, just before the S1 sound. It is caused by atrial contraction and increased resistance to ventricular filling.

Correct Answer is A

No explanation

A. Radial pulse in the left arm B. Radial pulse in the right arm C. Brachial pulse in the left arm D. Brachial pulse in the right arm

Correct Answer is A

Explanation

A. The radial pulse in the left arm can be palpated after a cardiac catheterization with a left antecubital insertion site. Although the focus is typically on the site of insertion and the brachial pulse, the radial pulse in the left arm can still provide useful information about circulation in that limb.
B. The radial pulse in the right arm is not pertinent because the catheterization was performed on the left side.
C. The brachial pulse in the left arm is indeed important to assess, but palpating the radial pulse in the left arm is also valid to check for circulation.
D. The brachial pulse in the right arm is not relevant in this scenario, as it does not relate to the site of catheterization.
