The nurse is listening to the heart sounds of a client. The nurse recognizes that the S2:
Indicates the beginning of diastole
Coincides with the carotid artery pulse
is louder than an S1
Is caused by the closure of the semilunar valves
The Correct Answer is D
A. Indicates the beginning of diastole: This statement is not accurate. S2, the second heart sound, indicates the end of systole and the beginning of diastole. It is specifically associated with the closure of the aortic and pulmonary valves.
B. Coincides with the carotid artery pulse: This statement is not accurate. S2 is associated with the closure of the aortic and pulmonary valves in the heart, not with the carotid artery pulse.
C. Is louder than an S1: This statement is not accurate. S1, the first heart sound, is usually louder than S2. S1 is associated with the closure of the mitral and tricuspid valves and marks the beginning of systole.
D. Is caused by the closure of the semilunar valves: This statement is accurate. S2 is caused by the closure of the aortic and pulmonary valves, which are the semilunar valves in the heart. It marks the end of systole and the beginning of diastole.

Correct Answer is A
Explanation
A. A slight asymmetry in breast size can be expected: This response is accurate. It acknowledges the natural variation in breast size that many women experience. It's common for one breast to be slightly larger or shaped differently than the other. It assures the client that this asymmetry is normal and not a cause for concern.
B. Asymmetry of breast size and shape is probably due to breastfeeding and is nothing to worry about: While breastfeeding can cause temporary changes in breast size and shape, not all cases of breast asymmetry are related to breastfeeding. This statement might not cover all situations, making it less accurate.
C. A sudden uneven increase in breast size is normal in adults: This statement is not accurate. Sudden changes in breast size should always be investigated, as they can indicate underlying health issues and may not be considered normal.
D. Breasts should always be symmetric: This statement is not accurate. Perfect symmetry in breast size and shape is rare. Most women have some degree of asymmetry, which is entirely normal. It's important to reassure the client that slight differences are common and not a cause for concern.
Correct Answer is C
Explanation
A. Fifth intercostal space, left of the midclavicular line: This placement is used to auscultate the mitral valve, which is best heard at the apex of the heart. The mitral valve sounds are typically heard around the fifth intercostal space, midclavicular line.
B. Left lower sternal border: This placement is used to auscultate the tricuspid valve, which is best heard at the lower left sternal border.
C. Second left intercostal space: This is the correct placement for auscultating the pulmonic valve. The pulmonic valve sounds are best heard at the second left intercostal space, which is close to the upper left sternal border.
D. Second right intercostal space: This placement is used to auscultate the aortic valve, which is best heard at the second right intercostal space, close to the upper right sternal border.
