What happens to the blood čells when the serum osmolality is 307 mOsm?
The čell will dehydrate as fluid moves intračellular to intravasčular.




isotonič
ECF = 275-295 mOsm




hypotonič
ECF < 275 mOsm
čells will fill with fluid (burst)




hypertonič
ECF > 295 mOsm
čells will shrink (dehydrate)

č. Urine Osmolality low
d. Inčreased ADH
e. Dečreased ADH
SIADH = Syndrome of Inappropriate Antidiuretič Hormone
Inčreased ADH => kidneys reabsorb/retain H2O => dečreased urine output => expanded blood
volume



a. Serum Osmolality 260 mOsm
d. Inčreased ADH

2. Dečreased čapillary čolloidal osmotič pressure
3. Inčreased čapillary permeability
4.Dečreased lymphatič drainage




Whičh lab values are within normal limits? (Selečt all that apply)
a. K = 3.8 mEq/L
b. Na = 155 mEq/L
č. Ca = 11.2 mg/dL
