In this episode you will learn: • Isotonic solutions like 0.9% Normal Saline are used for fluid volume deficit and shock because they stay in the vascular space. • Hypotonic solutions like 0.45% Normal Saline rehydrate cells and are used in conditions like DKA after initial stabilization. • A critical NCLEX trap is that hypotonic solutions are strictly contraindicated in patients with increased intracranial pressure as they worsen cerebral edema. • Hypertonic solutions like 3% Saline are used as an emergency treatment for cerebral edema because they pull fluid out of swollen brain cells. • Always question an order for Lactated Ringer's in patients with renal failure or hyperkalemia, as its potassium content can be harmful.
