1

the movement of fluid back and forth across the capillary wall

net filtration

2

pushing

hydrostatic pressure

3

pulling

oncotic pressure

4

facilitates the outward movement of water from the capillary to the interstitial space

capillary hydrostatic pressure (blood pressure)

5

osmotically attracts water from the interstitial space back into the capillary

capillary (plasma) oncotic pressure

6

facilitates the inward movement of water from interstitial space into the capillary

interstitial hydrostatic pressure

7

osmotically attracts water from the capillary into the interstitial space

interstitial oncotic pressure

8

is usually limited to the site of tissue injury
Ex. cerebral edema and pulmonary edema

localized edema

9

side effects of edema

weight gain
swelling
puffiness
impaired wound healing

10

rx of edema

elevation
compression
decrease in sodium intake
diuretics
underlying cause

11

refers to a solution that has the same concentration of solutes as the plasma

isotonic

12

develop when the osmolality of the ECF is elevated above normal

hypertonic fluid alteration

13

intercellular dehydration

hypovolemia

14

causes of edema

increased capillary hydrostatic pressure
decreased plasma protein
increased capillary permeability
lymph obstruction

15

causes of water deficit

hyperglycemia
severe diarrhea
diabetes insipidis

16

if extracellular concentrations increase without a significant change in the intracellular K concentration the resting membrane potential becomes more positive and the cell membrane is

hypopolarized

17

restores normal neuromuscular irritability

Ca gluconate

18

exchanges sodium for potassium

cation exchange resins

19

is elicited by tapping on the facial nerve just below the temple
A positive sign is a twitch of the nose or lip

chvostek sign

20

is contraction of the and and fingers when the arterial blood flow in the are is occluded for 5 min

Trousseau sign

21

calcium levels are less lag 8.5

hypocalcemia

22

RX for hypocalcemia

Ca replacement
decrease in HPO4 intake

23

calcium levels are greater than 12

hypercalcemia

24

Rx for hypercalcemia

oral HPO4 if renal function is WNL
IV naCl to increase renal excretion

25

normal arterial blood pH

7.35-7.45

26

How do you obtain blood pH

arterial blood gas

27

systemic increase in H concentration

acidosis

28

systemic decrease in H concentration

alkalosis

29

respiratory component

PaCO2

30

metabolic component

HCO3

31

increase in PCO2

respiratory acidosis

32

decrease in PCO2

respiratory alkalosis

33

decrease in HCO3

metabolic acidosis

34

increase in HCO3

metabolic alkalosis
