Flashcards in contin. carotid pulse Deck (34):
1

What type of info does the carotid pulse supply

detecting stenosis or insufficiency of the aortic valve

2

A tortuous and kinked carotid artery may produces what?

unilateral pulsatile bulge

3

What are causes of decreased pulsations

decreased stroke volume

4

Pressure on the carotid can cause what?

reflex drop in pulse rate or blood pressure

5

Small, thready, or weak pulse occurs where?

cardiogenic shock

6

A bounding pulse occurs where

aortic insufficiency

7

where is the carotid upstroke delayed

aortic stenosis

8

What happens in pulsus alternans

rhythm of pulse remains regular

9

what does pulsus altermans usually indicate

left sided heart failure

10

where is pulsus alternans usually best felt

applying light pressure on the radial or femoral arteries

11

what is paradoxical pulse

great than normal drop in systolic pressure during inspiration

12

What is a bruit

murmur like sound arising from a turbulent arterial blood flow

13

What causes a bruit

atherosclerotic narrowing of the internal carotid artery

14

If a patient has a carotid obstruction, kinking or thrill what should you access?

brachial artery

15

What is the position of the patient during the cardiac examination

patient should be supine

16

how do you assess the PMI

patient should be turned to the left lateral decubitus position

17

How do you bring the left ventricular outflow tract closer to the chest wall to listen for aortic insufficiency

have the patient sit up, lean forward and exhale

18

What is the relative intensity of sounds S1 and S2

S1 is usually louder than S2 at the apex

19

What is an invaluable aide to timing the sound or murmur

palpation of the carotid artery during the auscultation

20

What can inspection of the anterior chest reveal

location of the PMI

21

What can palpation of the anterior chest reveal

thrills

22

What is dextrocardia

heart situated in the right chest cavity

23

What is situs inversus

heart, tri-lobed lung, stomach and spleen are on the right side

24

What conditions can cause a more prominent pulsation than the apex beat

dilated pulmonary artery

25

what conditions may displace the apical pulse upward and to the left

pregnancy or a high left diaphragm

26

what conditions may cause a lateral displacement of the apical pulse

heart failure

27

A diffuse PMI > 3 in the lateral decubitus position indicate what?

ventricular enlargement

28

What can an increased amplitude of the impulse be caused by?

hyperthyroidism

29

What does a sustained high amplitude impulse that is normally located suggest

left ventricular hypertrophy from pressure overload (hypertension)

30

What does a sustained low amplitude suggest

dilated cardiomyopathy

31

A marked increase in amplitude with little or no change in duration occurs where

chronic volume overload of the right ventricle

32

An impulse with increased amplification and duration occurs where?

pressure overload of the right ventricle

33

What does a prominent pulsation over the left second interspace represent

increased pressure in the pulmonary artery

34

What does a prominent pulsation over the right second interspace represent

dilated or aneurysmal aorta
