NUR 339 Exam 3 Patho1. intracellular fluid (ICF)
Answer
majority of the fluids
2. extracellular fluids ECF
Answer
interstitial- around cells, intravascular/plasma- circulat- ing fluids, transcellular- other fluids-
spinal, digestive
3. total body water
Answer
60% body weight, ICF 40%, ECF 20%
4. fluid and solute movement basic principles
Answer
separated by semipermeable membranes, some allowed to pass freely, larger compounds
restricted
5. pressure gradient
Answer
between 2 sides of membrane causes the fluids and particles to move
6. high to low concentration
Answer
diffusion- movement of particles, osmosis- move- ment of water- passive, does not require
energy
7. low to high concentration
Answer
active transport, requires energy for movement to occur
8. osmolarity
,Answer
number of milliosmoles of solute per 1 kg of water 280-295
9. tonicity
Answer
ability of solutes to cause an osmotic gradient that promotes water movement- salt
concentration
10. tonicity determined by
Answer
how it compares to normal blood concentration
11. tonicity types
Answer
isotonic- equal to blood, hypertonic- concentrated blood hypo- tonic- dilute blood concentration
12. isotonic
Answer
concentration btwn solute and water balanced, no net movement btwn ICF and ECF, no change
in cells
13. hypotonic
Answer
ECF less concentrated, dilute vascular space with concentration of solutes in the cells, net
movement from ECF> ICF, cell size increases due to fluid incerease
14. hypertonic solution
Answer
ECF more concentrated, pulls fluid from cells to blood, ICF> ECF, cell size shrinks
15. capillary hydrostatic pressure
Answer
pressure exerted by fluids against bld vessel walls- reflects BP, pressure is higher at arterial end,
lower at venous
, 16. filtration
Answer
movement of fluid from hi pressure to low, hi arterial pressure pushes fluids out of capillary to
ICF, fluids reabsorbed in lower pressure venous system with osmotic pressure
17. hydrostatic pressure pushes
Answer
fluids out to ICF
18. osmotic pressure pulls
Answer
fluids into ECF
19. colloid oncotic pressure
Answer
osmotic pressure from albumin, contributes to os- motic pressure in venous end
20. fluid intake
Answer
primary thru diet
21. fluid loss
Answer
through kidneys, lungs, skin, GI
22. conditions that affect TBW (total body water)
Answer
V D, dehydration, renal func- tion, HF, burns, meds
23. evaluating fluid status
Answer
I&O, serum osmolarity, urine specific gravity, Hgb/Hct
