21
Q

What does a thrill in the 2nd and 3rd RIGHT interspaces indicate?

A

Aortic stenosis and systemic hypertension

22
Q

What nursing interventions help prevent thrombus formation?

A
  1. Identify at risk patients
  2. Leg exercises

23
Q

What is it called when mitral and tricuspid components are heard separately?

A

Split S1, normal but uncommon

24
Q

If a patient presents with faint (diminished) S1, what could that be indicative of?

A

First-degree heart block
Mitral insufficiency
Severe hypertension

25
Q

If a patient has a loud (accentuated) S1, what could that indicate?

A

Increased blood velocity, due to exercise, fever, anemia, or hyperthyroidism. Possible mitral stenosis.

26
Q

If a patient has ductus arteriosus, what sound would be heard?

A

Paradoxical S2 Split

27
Q

A gentle, blowing, swooshing sound that can be heard through the chest wall

A

Murmur

28
Q

What sounds are hear at Mid-Diastole?

A

What sound can be heard with increased afterload?

A

30
Q

These sounds can be heard during diastole

A

S3 and S4

31
Q

Opening in the atrial septum

A

Foramen ovale

32
Q

What does an apical impulse indicate?

A

Pressure overload = aortic stenosis or systemic HTN

33
Q

What nursing interventions reduce cardiac workload?

A
  1. Encourage breathing while moving

2. Increase mobility

34
Q

If a nurse hears a split S2 on expiration and inhalation, she knows this could indicate:

A
  1. Atrial septal defect

2. R ventricular failure

35
Q

What could cause a diminished S2?

A
  1. Decreased valve strength due to decreased BP (shock)

2. SL valves thickened and calcified (aortic or pulmonic stenosis)

36

A

S4

44
Q

What sound can be heard during mid-diastole that is prolonged and often louder than S1 and S2?

A

Summation sound (S3 and S4)

45
Q

If a patient presents with a split S1, what could that be indicative of?

A

Normal but uncommon

Mitral and tricuspid components heard separately

46
Q

What sound is heard just after S1, at base only, and is louder on expirations?

A

Pulmonic ejection click

47
Q

If a patient has decreased compliance if the ventricles, what sound is heard?
