both the diaphragm and bell

Question 24

What is the vascular assessment used for

Answer 24

to identify signs and symptoms of peripheral vascular disease

What do you do during a vascular assessment (3)

Answer 25

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

Question 26

What are the 8 pulse sites

Answer 26

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

Question 27

Describe the aortic valve

Answer 27

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

Question 28

Describe the pulmonic valve

Answer 28

2nd intercostal space, left sternal border

Question 29

Answer 29

3rd intercostal space, left sternal border

Question 30

Describe tricuspid valve

Answer 30

4th intercostal space, left sternal border

Question 31

Describe mitral valve (apical pulse)

Answer 31

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

Question 32

Describe the S1 sound

Answer 32

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

Question 33

Describe the S2 sound

Answer 33

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

Question 34

Describe the S3 sound

Answer 34

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

Question 35

Describe the S4 sound

Answer 35

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

Describe a heart murmur

Answer 39

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

Question 40

What do you do if a heart murmur is detected

Answer 40

do further assessment

Question 41

Thrill

Answer 41

vibration felt while checking the pulse
