Question

The nurse is auscultating a client's heart sounds and notes a murmur at the left fourth intercostal space and lateral to the sternum. At which cardiac valve would the nurse document this murmur?

A) Tricuspid valve
B) Mitral valve
C) Pulmonary valve
D) Aortic valve

Answer 1

The nurse would document the murmur at the mitral valve.

Step-by-step explanation:

The nurse would document the murmur at the left fourth intercostal space and lateral to the sternum at the mitral valve. The mitral valve, also known as the bicuspid valve or the left atrioventricular valve, is located between the left atrium and left ventricle. It consists of two cusps and is attached by chordae tendineae to papillary muscles.
