Flashcards in Fluid Assessment and Balance Deck (22)
what is mainly in the extracellular compartment?
what is mainly in the intracellular compartment?
high sodium content means what for the ECV?
higher volume in ECV
how to calculate the osmolality concentration quickly?
Glucose, urea, Nax2
ECV vary with water intake?
Not really, mostly osmolar content
ICV varies with water intake?
total body water is circa___%?
how to adjust ECV?
modify Na and water
how to adjust ICV?
modify water only intake
2 causes of high plasma osmolality:
1. not enough water in
2. not enough Na+ out
low plasma osmolality/sodium can lead to what 2 presentations?
how do you get low plasma osmolality/sodium?
increased water intake
3 causes of increased water intake in body/drugs
ECV correlates with blood volume unless?
what's normal K+ levels?
abnormal K+ can reflect?
shift between ICV/ECV or deficientcy/excess
what 4 things shifts K+ into cells?
plasma sodium does not tell you:
body sodium content
since intracellular osmols are relatively constant, what reflects intracellular volume?
