Homeostasis Flashcards
(37 cards)
what are some risks for dehydration
diarrhea vomiting infection fever burns decreased fluid intake
what percent is mild dehydration
0-5%
what percent is moderate dehydration
6-9%
what percent is severe dehydration
10-15%
what percent of dehydration is incompatible with life
> 15%
what is the most common type of dehydration
isotonic
isotonic dehydration:
sodium and water losses are
equal
isotonic dehydration:
sodium values are normal or abnormal
normal
isotonic dehydration:
the major fluid loss is from ICF or ECF
ECF
hyportonic dehydration:
sodium deficit is > or < water deficit
greater
hyportonic dehydration:
sodium values are increased or decreased
decreased
hyportonic dehydration:
ICF or ECF is more concentrated
ICF
hyportonic dehydration:
water moves from
ECF to ICF
into the cells
hypertonic dehydration:
water loss is > or < sodium loss
greater
hypertonic dehydration:
fluid shifts from
ICF to ECF
out of cells
hypertonic dehydration:
sodium values are increased or decreased
increased
what is a major concern associated w/ hypertonic dehydration
increased intracranial pressure
what would VS look like with increased intracranial pressure
decreased P, R
increased BP
s/s: decreased appetite weight loss low grade fever no wet diaper x 4 hours
mild to moderate diarrhea & dehydration
s/s: high fever progressive weight loss no wet diaper x 4-6 hours metabolic acidosis
severe diarrhea & dehydration
