Flashcards in mish mash Deck (42):
1

vagus nerve

activation typically leads to reduction in HR, BP, or both

if circulatory changes are great enough, vasovagal syncope (sudden drop in CO causes cerebral hypoperfusion)

parasympathetic

2

suction nota bene x4

1. hyperoxygenate with 100% O2 - 2 minutes before and after

2. stop advancing catheter upon meeting resistance or at cough

3. suction when going out, intermittent, no longer than 10 seconds

4. can stimulate vagus nerve - HR drops (stop and hyperoxygenate)

3

pernicious anemia

decrease in red blood cells when the body can't absorb enough vitamin B-12

risk factor for stomach cancer

4

achlorhydria

absence of hydrochloric acid in the gastric secretions

risk factor for stomach cancer

5

s/s stomach obstruction + tx

abdominal distention
N/V
pain

tx: NPO, NG tube to suction for decompression

6

Schilling's Test

measures urinary excretion of B-12 for dx of pernicious anemia

7

primary prevention

prevent actual occurrence (sunblock, not smoking, etc)

8

secondary prevention

screenings to detect early disease - greater chance for cure or control

9

infiltration vs extravasation

leak vs irritant

10

s/s extravasation

pain, swelling, no blood return

11

dehiscence

wound separating

12

evisceration

organs out

13

mydriasis

pupil dilation

14

miosis

pupil constriction

15

venturi mask

most accurate oxygen delivery system

patients at risk for CO2 retention (ex: COPD patients) benefit because FiO2 can be controlled

16

nasal canula

low-flow delivery system

17

aerosol mask

most often used for high humidity

18

BiPAP (use)

when additional pressure support needed with ventilation

19

due to severe neck stiffness, if neck is flexed, hips and knees flex

22

Cullen's sign

superficial edema and bruising in sq fat tissue around belly button

indicative of
- severe, acute pancreatitis (most common)
- ruptured ectopic pregnancy

23

Ortolani's sign

test for developmental dysplasia of the hip in kiddoes

- flex infant hip/knees to 90 degrees
- anterior pressure on greater trochanter
- abduct

positive: clunk

24

papule

solid elevated lesion not containing fluid

25

pustule

26

nodule

ex: freckle

29

bulla

blister

30

Grey Turner's Sign

bruising of the flank

per Jud, see this and you're fucked because SEVERE acute pancreatitis

31

contact precautions

- private room or cohort client
- gloves, gown when in contact with client

for direct (care, handling contaminated body fluids) and indirect contact (fomites; contaminated instruments or hands) with patients and their environment
- MRS. WEE

32

droplet precautions

- surgical mask w/in 3 feet of pt
- hand hygiene
- dedicated care equipment
- private room (or cohort client)
- mask on client when leave room

for disease transmitted by large droplets that travel 3-6 feet - SPIDERMAn

33

airborne precautions

- negative air flow room (private)
-- min 6 to 12 air exchanges / hour
- UV germicide irradiation/high efficiency air
- filter mask, N95 respirator for TB
- mask on client when leaves room (only if necessary)

diseases transmitted by smaller droplets that remain in air for longer - "My Chicken Hez TB"

34

scoliosis

lateral

35
