Flashcards in Blood Pressure Deck (26):
1

what is being measured with blood pressure

the arterial wall force

2

what are the 4 factors that determine blood pressure readings

the force of the blood pumped, amount of blood pumped, size of arteries, and flexibility of arteries

3

how much can the reading vary from right to left arm

as much as 5mmHg

4

what are 5 reasons to screen BP in clinic

compliance, reinforce importance of compliance, silent disease, may see effect in vision or retina, and drugs prescribed may increase BP

5

what is hypertensive retinopathy

a manifestation of the disease in the eye

6

what are 4 potential findings on the retina from BP

retinal arteries may narrow and constrict, hemorrhages and exudates, local hypoxia= cotton wool spots, and papilledema

7

what are 6 other conditions that BP can cause in the eye

sub-conjunctival hemorrhage, retinal vein occlusion, retinal artery occlusion, retinal artery macroaneurysms, oculomotor palsies, and exudative retinal detachments

8

what 2 diseases can hyper or hypotension cause

OAG (open angle glaucoma) and amaurosis fugax

9

what are 2 types of hypertension

essential hypertension and secondary hypertension

10

what is essential hypertension

no identifiable underlying cause

11

what is secondary hypertension

pre-eclampsia, pheochromocytoma, kidney disease, or adrenal disease

12

what does the JNC 7 consider normal BP

less than 120/80

13

what does the JNC 7 consider pre-hypertensive BP

120-139/80-90

14

what does the JNC 7 consider stage 1 hypertension

140-159/90-99

15

what does the JNC 7 consider stage 2 hypertension

>160/>99

16

what is malignant hypertension

extremely high blood pressure

17

what are the findings in malignant hypertension

all the findings of hypertensive retinopathy plus swollen optic nerve head (occipital headaches)

18

what is pre-eclampsia/eclampsia hypertensive retinopathy

20 weeks gestation, all findings of malignant hypertension, at risk for cortical blindness and occipital lobe infarction

19

when do you refer patients with blood pressure

when symptoms (chest pain, headache, difficulty breathing, blurred vision, diastolic over 110/120) call 911

20

how wide is a sphygmanometer

12-14cm wide

21

what is a stethoscope used for

to listen to the sound of the blood in the brachial artery after first compressing it completely and then letting it flow

22

when should a BP be taken

after 5 minutes of rest and 30 minutes after exercise/caffeine/smoking

23

how do you estimate the systolic pressure

palpate radial artery, inflate cuff 30mmHg above where pulse disappears, deflate 2-3mmHg until pulse returns

24

what are the 5 phases of the Korotkoff sounds

1. soft tapping (systolic reading)
2. swishing murmur
3. crisper sound
4. abrupt sound muffling
5. disappearance of sound (diastolic reading)

25

how long do you listen after the disappearance of sound at the end of taking a BP

after 20-30mmHg after last sound

26

how do you record the BP

120/80mmHg R.A.S 5pm. Adult cuff
