Quiz 4 Midweek Comprehension Quiz

Question 1

2 / 2 pts

According to the lesson, low-pitched sounds of S3 and S4 and the murmur of mitral stenosis are best

heard using what?

 The naked ear

 The diaphragm of the stethoscope

Correct!

 The bell of the stethoscope

 The bell and diaphragm are equally effective for this task

Listen throughout the precordium with the diaphragm, pressing it firmly against the chest. The bell is

more sensitive to the low-pitched sounds of S3 and S4 and the murmur of mitral stenosis. Apply the

bell lightly, with just enough pressure to produce an air seal with its full rim. Use the bell at the apex,

then move medially along the lower sternal border. Resting the heel of your hand on the chest like a

fulcrum may help you to maintain light pressure.

heard during inspiration over which area on the chest wall?

 Apex

heart sound, the S2 sound is described regarding splitting and intensity.
