Q

Where do you listen to heart sounds

A

aortic, pulmonic, erb’s point, tricuspid, mitral

20
Q

How long do you listen to heart sounds

A

1 minute in each spot

21
Q

What is a cardiovascular assessment used for

A

help identify significant factors that influence cardiovascular health

22
Q

Should the cardiovascular exam be done as a part of each head-to-toe exam

A

yes

23
Q

What part of the stethoscope should you be using to listen to heart sounds

A

both the diaphragm and bell

24
Q

What is the vascular assessment used for

A

to identify signs and symptoms of peripheral vascular disease

25
Q

What do you do during a vascular assessment (3)

A

inspect skin/mucous membrane color, general appearance, palpate pulse/skin/temperature/capillary refill/edema/areas of tenderness

26
Q

What are the 8 pulse sites

A

temporal, carotid, brachial, radial, dorsalis pedis, femoral, popliteal, posterior tibial

27
Q

Describe the aortic valve

A

2nd intercostal space, right sternal border, hear S2 noise best here (diastole)

28
Q

Describe the pulmonic valve

A

2nd intercostal space, left sternal border

29
Q

Describe Erb’s point

A

3rd intercostal space, left sternal border

30
Q

Describe tricuspid valve

A

4th intercostal space, left sternal border

31
Q

Describe mitral valve (apical pulse)

A

5th intercostal space, midclavicular line, hear S1 sound best here (systole)

32
Q

Describe the S1 sound

A

Lub, created by the closure of the mitral and tricuspid valves, beginning of systole, dull low pitched sound

33
Q

Describe the S2 sound

A

Dub, created by the closure of the aortic and pulmonic valves, beginning of diastole, high pitched and shorter than S1

34
Q

Describe the S3 sound

A

An extra sound heard after S1, gallop cadence (KenTUCKy), best heard at the apical site in a side laying position

35
Q

Describe the S4 sound

A

An extra sound heard before S1, FLOrida, best heard at apical site using bell in a side-laying position

36
Q

What is a normal heart rate

A

60-100 bpm

37
Q

When are heart sounds louder

A

as a child

38
Q

What is a normal capillary refill time

A

less than 3 seconds

39
Q

Describe a heart murmur

A

turbulent blood flow with a swooshing or blowing sound when listening,

40
Q

What do you do if a heart murmur is detected

A

do further assessment

41
Q

Thrill

A

vibration felt while checking the pulse

42
Q

Bruit

A

audible sound blood makes as it moves through arteries

43
Q

What are the pulse strengths

A

0: absent
+1: weak
+2: normal
+3: strong
+4: bounding

44
Q

Developmental differences in infants/children for heart and vascular system

A

-Cyanosis when feeding? Crying?
-Poor feeding?
-Keep up with other kids?
-Blue spells?
-What are naps like?
-Joint pain? Fever?

45
Q

Developmental differences in older adults

A

-Stopped taking any medications?
-Does illness interfere with ADLs?
-Stairs in home?
-The pain perception is going to be different and diminished
