Question

during auscultation, you hear lub - dub - swish, lub - dub - swish. this is loudest at the first heart auscultation point. what is the most likely cause?
aortic valve stenosis
pulmonic valve stenosis
aortic valve regurgitation
mitral valve stenosis
pulmonic valve regurgitation

Explanation:

The "swish" sound during auscultation is indicative of a murmur. Aortic valve regurgitation is associated with a high - pitched blowing murmur that is often loudest at the first heart auscultation point. Aortic valve stenosis has a harsh systolic ejection murmur, pulmonic valve stenosis has a systolic murmur best heard over the pulmonic area, mitral valve stenosis has a low - pitched, rumbling diastolic murmur, and pulmonic valve regurgitation has a diastolic murmur best heard over the pulmonic area.

Answer:

C. Aortic valve regurgitation
