Answer 10

Vibrations

Question 11

What causes the S1 sound?

Answer 11

Closure of tricuspid and mitral valves

Question 12

Is the “lub” sound the start or end of systole?

Answer 12

Start of systole

Question 13

Answer 13

Closure of aortic and pulmonic valves (SL valves)

Question 14

What are the precordial areas for auscultation?

Answer 14

Aortic, Pulmonic, tricuspid, and mitral

Question 15

What is a split sound?

Answer 15

When valves are not closing at the same time

Question 16

The S3 ( ventricular gallop) sound occurs right after S2, what creates it?

Answer 16

When ventricles are resistant in early rapid filling phase

Question 17

S4 occurs right before S1, what creates it?

Answer 17

From resistance in the ventricles when filling at the end of diastole

Under what conditions can S3 be pathologic? (5)

Answer 26

- older adult - HTN - volume overload (CHF) - mitral regurgitation - high output states (thyroid,anemia)

Question 27

T/F. An S4 (atrial gallop) is rarely physiologic?

Answer 27

True

Question 28

What 7 things can create murmurs?

Answer 28

- Increased flow through normal structures under conditions like exercise or hyperthyroidism. - back flow or regurgitation - flow through narrow or obstructed valves - flow into dilated chambers - decrease in blood viscosity - shunting into abnormal passages - calcification of the aorta

Question 29

Turbulent blood flow outside of the heart is called what?

Answer 29

Bruit

Question 30

What is claudication?

Answer 30

When muscles are not getting enough oxygen causing pain. Associated with arterial insufficiency.
