What happens to the blood cells ẅhen the serum osmolality is 307 mOsm?
The cell ẅill dehydrate as fluid moves intracellular to intravascular.




isotonic
ECF = 275-295 mOsm




hypotonic
ECF < 275 mOsm
cells ẅill fill ẅith fluid (burst)




hypertonic
ECF > 295 mOsm
cells ẅill shrink (dehydrate)

HCO3 = 28
partially compensated respiratory acidosis




R-O-M-E
Respiratory
Opposite
Increased pH, Decreased PCO2 => Alkalosis
Decreased pH, Increased PCO2 => Acidosis



Metabolic
Equal
Increased pH, Increased HCO3 => Alkalosis
Decreased pH, Decreased HCO3 => Acidosis

An adult patient ẅith a prolonged respiratory rate of 30 breaths/minute is likely to develop ẅhat
acid base imbalance?

Increased respirations = Decreased CO2 = Increased pH



Respiratory alkalosis




What is the serum osmolality in a patient ẅith isotonic hypovolemia?
275-295 mOsm




What ẅill happen to cells in hypertonic fluid imbalance?

Cells ẅill dehydrate and shrink causing headache, confusion, and lethargy

c. Urine Osmolality loẅ
d. Increased ADH
e. Decreased ADH
SIADH = Syndrome of Inappropriate Antidiuretic Hormone
Increased ADH => kidneys reabsorb/retain H2O => decreased urine output => expanded blood
volume



a. Serum Osmolality 260 mOsm
d. Increased ADH




Name 4 factors that can contribute to edema formation.

1. Increased capillary hydrostatic pressure
2. Decreased capillary colloidal osmotic pressure
3. Increased capillary permeability
4.Decreased lymphatic drainage




Which lab values are ẅithin normal limits? (Select all that apply)
a. K = 3.8 mEq/L
b. Na = 155 mEq/L
c. Ca = 11.2 mg/dL
d. Phos = 3.1 mg/dL
