Flashcards in jensen2 Deck (63):
1

best indicator liver synthetic ability

PT

2

best indicator liver excretory function

bilirubin

3

anion gap

Na - (Cl + HCO3)

4

increased anion gap

LUK SEMP - lactic acidosis, uremia, ketoacidosis, salicylates, ethylene glycol, methanol, paraldehyde

5

large a waves

MS, heart block, atrial myxoma

6

large v waves

MR, MS, CHF, VSD

7

ascites with hepatic failure

decreased intravascular oncotic pressure

8

citrate toxicity symptoms

hypotension, poor CO, decreased SVR - aggravated by hypothermia and hyperkalemia (more pronounced with renal failure)

9

increased risk for TNS

lidocaine, lithotomy, out patient

10

altitude change and gas

high altitudes/lower atmospheric pressure = increased vapor pressure (higher amount delivered than on dial)

11

nitrogen wash out

breathe 100% O2, measure nitrogen volume at initial concentration and final to calculate FRC

12

biceps strength dermatome

C5-C6

13

thumb dermatome

C6

14

triceps strength dermatome

C7-C8

15

little finger dermatome

C8

16

nipple dermatome

T4-5

17

umbilicus dermatome

T10

18

iliopsoas strength dermatome

L2-3

19

knee jerk/quads dermatome

L3-4

20

toe extension dermatome

L4-5

21

great toe dermatome

L5

22

plantar flexion dermatome

S1

23

factor Xa mechanism of action

catalyzes conversion of prothrombin to thrombin

24

clopidogrel/ticlopidine

noncompetitively and irreversibly inhibits ADp induced platelet aggregation

25

argatroban metabolism and monitor

metabolized by liver, monitor with PTT (used for patients with history of HIT)

26

lepirudin mechanism and metab

direct thrombin inhibitor; renally cleared (used for patients with history of HIT)

27

argatroban mechanism

direct thrombin inhibitor (liver metabolism)

28

fondaparinux (arixtra) mechanism

inhibitor of activated factor X (for DVT prophylaxis)

29

best indication of ischemia in OR

(TEE) lead II and V ST depression is 95% sensitive

30

treat heparin resistance

FFP or recombinant antithrombin III

31

common MAOIs

Isocarboxazid (Marplan), Phenelzine (Nardil)
Selegiline (Emsam), Tranylcypromine (Parnate)

32

face mask flow and %

8-10 L/min; 40-60%

33

nasal cannula O2 enhancement

4-5% per liter (max ~55%)

34

nasal cannula reservoir

concentration of O2 is function of oxygen flow rate (does not exceed peak inspiratory flow rate for normal tidal 40 L/min) and minute ventilation - hypovent=FiO2 high vs hypervent=FiO2 low

35

venture mask

FiO2 is independent of minute ventilation and inspiratory flow rate - oxygen concentration can be controlled

36

NO mechanism

acetylcholine stim release of NO which stim cGMP - decrease in intracellular calcium

37

highest MAC requirements

2-3 months old

38

sevo/mac/peds

same MAC for neonates and infants

39

hyperaldosteronism

HTN, hypokalemia (ass with polyuria and polydipsia), treat with aldosterone antagonist spironolactone

40

fluid for craniotomy

NS ok, avoid solutions with glucose, avoid LR (273 osm) because decreases plasma osm and may increase incidence of cerebral edema

41

avoid CMV in blood products

WBC washed

42

hyperventilation treats...

hyperkalemia

43

baclofen mechanism

GABA B agonist that works centrally

44

baclofen se

drowsiness, dizziness, GI symptoms, confusion, hypotension

45

central retinal artery

ass with venous drainage obstruction or cardiac surgery with emboli; cherry red macula

46

ant ischemic optical neuropathy

ass with older, DM, HTN, SLE, open heart surgery; unilateral blindess 2/2 pressure on globe

47
