What is third spacing and what are examples?
Fluid shift into nonfunctional spaces — edema, effusion, ascites, anasarca.
How can a patient be both hypovolemic and edematous at the same time?
Low intravascular volume with fluid retained in third spaces.
What are the normal values for serum osmolality and what do high and low
values indicate?
270-300 mOsm/kg
↑in dehydration
↓in fluid volume overload
What are the normal values for urine osmolality and what does a high and low
level indicate?
300-900 mOsm/kg
↑in dehydration
↓in fluid volume overload
Normal BUN range and what does it measure?
10-20 mg/dL.
End product of dietary protein catabolism.
Short-term hypovolemia effect on BUN?
↑ BUN.
Normal creatinine range and what does it measure?
0.5-1.2 mg/dL.
End product of muscle breakdown.
Long-term hypovolemia effect on creatinine?
↑ creatinine.
Main cause of ↑ creatinine besides hypovolemia?
Poor renal function (CKD).
Normal GFR and what does a low level indicate?
>90%.
Low GFR = poor renal function or hypovolemia.
Normal hematocrit range?
40-50%.
Hypovolemia and hypervolemia effects on hematocrit?
Hypovolemia: ↑ hematocrit.
Hypervolemia: ↓ hematocrit.
Signs of hypovolemia?
, Low BP and reflex tachycardia (+ other fluid deficit signs).
Signs of hypervolemia?
Hypertension and tachycardia (+ other fluid excess signs).
Normal Na⁺ range and key symptoms of imbalance?
135-145 mEq/L
Neurological changes (confusion, seizure, coma), muscle weakness/fatigue.
Hypernatremia treatment goal?
Gradually lower Na⁺ to avoid cerebral edema.
Hyponatremia treatment goal?
Gradually raise Na⁺ to avoid demyelination and worsening neuro deficits.
Safety concerns for sodium imbalances?
Seizure precautions, fall prevention.
Normal K⁺ range and where is most K⁺ located?
3.5-5.0 mEq/L; mostly in ICF.
What are two common causes of hyperkalemia?
Renal failure, acidosis.
Hyperkalemia key signs and EKG findings?
Weak/depressed activity, peaked T waves.
Acute hyperkalemia treatments & MOAs?
10U regular insulin IVP + 50 mL D50 (shifts K⁺ into cells; D50 prevents hypoglycemia)
Calcium gluconate IV (binds K⁺, protects heart)
Sodium bicarbonate IV (reverses acidosis)
Hemodialysis
Chronic hyperkalemia treatments?
Sodium polystyrene sulfonate (PO/NG/enema), loop diuretics (furosemide).
Hypokalemia signs and treatment order?
Weak/depressed except ventricles.
Replace Mg²⁺ before replacing K⁺ (Never IVP, dilute, push slow)
Encourage K⁺-rich diet.
Normal Mg²⁺ range?
1.6-2.2 mg/dL; mostly ICF.
Hypermagnesemia signs and treatments?
Weak/slow.
Treat with diuretics + IV fluid, calcium gluconate IV (protects heart).
Hypomagnesemia signs and treatments?
Fast/irritable except GI.
Treat with IV Mg sulfate or banana bag
Never IV push (give over 30-60 min).
Normal total and ionized Ca²⁺ ranges?
