What happens to the blood cells when the serum osmolality is 307 mOsm?
The cell will dehydrate as ғluid moves intracellular to intravascular.




isotonic
ECF = 275-295 mOsm




hypotonic
ECF < 275 mOsm
cells will ғill with ғluid (burst)




hypertonic
ECF > 295 mOsm
cells will 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




pH value
7.35-7.45




PCO2 value
35-45 mmHg

HCO3 value
22-26 mEq/L




An adult patient with a prolonged respiratory rate oғ 30 breaths/minute is likely to develop what
acid base imbalance?
Increased respirations = Decreased CO2 = Increased pH


Respiratory alkalosis




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




What will happen to cells in hypertonic ғluid imbalance?
Cells will dehydrate and shrink causing headache, conғusion, and lethargy

c. Urine Osmolality low
d. Increased ADH
e. Decreased ADH
SIADH = Syndrome oғ 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 ғactors that can contribute to edema ғormation.

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




Which lab values are within 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
