Fluids & Electrolytes Flashcards
1
Q
Intravascular
A
fluid inside a blood vessel
2
Q
Intracellular
A
fluid inside a cell
3
Q
Extracellular
A
fluid outside cells
4
Q
Isotonic (= concentration in cell)
A
No osmotic force w/in cells –> increase extracellular fluid volume
for dehydration r/t n/v
0.9% NS
D5W
Lactated Ringers
5
Q
Hypotonic (low concentration w/in cell)
A
fluids move OUT of extracellular space and into cell
given for dehydrated cells (DKA, hyperosmolar hyperglycemia)
DO NOT GIVE FOR INCREASED ICP, burns, or trauma –> will cause cell swelling
- 45% NS
- 22% NS
- 33 % NS
6
Q
Hypertonic (excessive concentration w/in cell)
A
fluids move out of cells into vascular space
given for swollen cells (cerebral edema)
may cause fluid overload
