Electrolyte replacement for hypokalemia (loop/thiazide diuretic-induced, vomiting, hyperaldosteronism). Plasma K+ is homeostatically regulated by renin-aldosterone-distal nephron and Na+/K+ ATPase — total-body K+ is intracellular, plasma reflects only ~2%. Therapeutic range narrow (3.5-5.0 mmol/L); toxicity above ~6 causes cardiac arrhythmia.
