The nurse is assessing the heart sounds of a client. The nurse understands that to listen to the pulmonic valve, the stethoscope should be placed where?
Fifth intercoastal space, left of the midclavicular line
Left lower sternal border
Second left intercoastal space
Second right intercoastal space
The Correct Answer is C
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.

Correct Answer is C
Explanation
A. Bronchovesicular breath sounds and normal in that location:
Bronchovesicular breath sounds are medium-pitched sounds heard over the major bronchi and are usually equal on inspiration and expiration. They are typically heard in the 1st and 2nd intercostal spaces anteriorly and between the scapulae posteriorly. While they might be normal in certain locations, hearing them over peripheral lung fields might indicate an abnormality.
B. Normally auscultated over the trachea:
This statement doesn't specify a particular type of breath sound. Tracheal breath sounds are harsh and relatively high-pitched, heard directly over the trachea. They are normal over the trachea but are not normally heard in the lung periphery.
C. Vesicular breath sounds and normal in that location:
Vesicular breath sounds are low-pitched, soft sounds heard over most of the lungs during inspiration. They are longer on inspiration than expiration and are considered normal breath sounds heard in the peripheral lung fields. Hearing vesicular sounds in the posterior lower lobes is typical and indicates normal lung function.
D. Bronchial breath sounds and normal in that location:
Bronchial breath sounds are high-pitched and loud, heard primarily over the trachea and larynx. If heard in the peripheral lung fields, especially in the lower lobes, it can suggest an abnormality such as consolidation or compression of lung tissue.
