Health Assessment #5 - Heart, Neck Vessels, and Peripheral Vascular System

Question 1

Closure of AV (mitral and tricuspid) valves. Loudest at apex. Systole onset. Synchronous with carotid pulse.

a. ) S1
b. ) S2
c. ) S3
d. ) S4

Answer 1

a.) S1

High-pitch, lower than S2

Question 2

Closure of semilunar (aortic and pulmonic) valves. Loudest at the base. Diastole onset. High pitched.

a. ) S1
b. ) S2
c. ) S3
d. ) S4

Answer 2

b.) S2

Question 3

Early diastole ventricular filling. Heard at apex or lower sternal border. Low-pitched. Decreased ventricular compliance. Early sign of heart failure.

a. ) S1
b. ) S2
c. ) S3
d. ) S4

Answer 3

c.) S3

Question 4

Late diastole ventricular filling due to atrial contraction. Heard at apex. Low-pitched. Increased resistance to filling due to loss of ventricular wall compliance.

a. ) S1
b. ) S2
c. ) S3
d. ) S4

Answer 4

d.) S4
