how to inspect external jugular venous pulsations

Answer 8

External jugular veins
Location: Over sternomastoid muscle
Present or full

Question 9

how to inspect internal jugular venous pulsations

Answer 9

Internal jugular pulsation
Location: Suprasternal notch or origin of sternomastoid muscle
Diffuse with two visible waves

Question 10

internal jugular characteristics

Answer 10

lower, undulant diffuse with 2 visible waves.
disappears as person sits up

Question 11

carotid pulse

Answer 11

higher, medial to sternomastoid muscle,
-brisk, localized with one wave
-does not vary with R
-unaffected by position

Question 12

cardiovascular system is made up of 2 things

Answer 12

heart and blood vessels

Question 13

the two types of blood vessels

Answer 13

pulmonary and systematic circulation

Question 14

the heart landmarks

Answer 14

• precordium
• mediastinum

Question 15

layers of the heart

Answer 15

pericardium-outer layer
epicardium
myocardium- muscular layer of the heart
endocardium- innermost layer of the heart

Question 16

what are the 4 valves

Answer 16

atrioventricular
- tricuspid
- mitral/bicuspid

semilunar
- pulmonic
- aorta

Question 17

the 2 types of circulation

Answer 17

systematic and pulmonary

Question 18

what are the 2 phases of the cardiac cycle

Answer 18

systole and diastole

Question 19

diastole

Answer 19

• pressure is greater in atria than ventricles
• av valves open
• ventricles fills

atrial kick
- 25% of stroke volume

Question 20

systole

Answer 20

• ventricular pressure greater than atrial
• AV valves close (sound of S1 “lub”
• all 4 valves closed
• pressure builds in ventricles
• SL valves open and ventricles contract
• ventricular pressure falls below aortic
  (SL valves comes sound of S2 “dup”)

Question 21

what is split t-dup

Answer 21

its because the aortic valve closers earlier than pulmonic
- more to the right heart
- less to the left

Question 22

electrical conduction system is made up of

Answer 22

• the cardiac cycle
• abilities of cardiac muscle cells
• the pathway of the electrical conduction system of the heart

Question 23

what is CO

Answer 23

cardiac output is the amount of blood pumped by ventricles during 1 min.

Question 24

whats the measurement for CO

Answer 24

stroke volume x HR= CO

Question 25

developmental considerations - infant and children

Answer 25

• foramen ovale
• ductus arteriosus
• position of heart in chest apex higher

Question 26

developmental considerations- pregnant women

Answer 26

• increase in blood volume
• increase in stroke volume and cardiac output

Question 27

developmental considerations- older adult

Answer 27

• influence in lifestyle
• increase in systolic blood pressure
• decreased tolerance

Question 28

socioeconomic factors

Answer 28

• high blood pressure
• smoking
• serum cholesterol
• obesity
• diabetes

Question 29

subjective data

Answer 29

• chest pain
• dyspnea
• orthopnea
• cough
• fatigue
• cyanosis
• edema
• nocturia
• cardiac hx
• family cardiac hx
• personal habits (cardiac risk factors)

Question 30

landmarking the body (the 3 lines)

Answer 30

• midsternal
• midclavicular
• anterior axillary line

Question 31

precordium (objective exam) inspect

Answer 31

Inspect the anterior chest- can use tangential light

Question 32

precordium (objective exam) palpation

Answer 32

Palpate the apical impulse and pulsations
heaves or lifts due to enlarged ventricle d/t overload

Question 33

precordium (objective exam) 3 sites of palpation

Answer 33

Palpate across the precordium 3 locations
At 5th ICS at midclavicular line
Left Sternal Border
Base of Heart
Assessing for Thrills

Question 34

precordium- supine, what are you feeling for?

Answer 34

apex, left sternal border, base
- normally no pulsations/thrills felt

Question 35

the apical pulse is only palpable in what % of the population

Answer 35

50%

Question 36

where to auscultate the apical pulse

Answer 36

Landmark
5th ICS at left MCL (same location as the mitral valve)
Note rate & rhythm

Question 37

auscultatory location for the tricuspid valve

Answer 37

4TH ICS at L sternal border

Question 38

auscultatory location for mitral valve

Answer 38

5TH ICS at left MCL

Question 39
