- Hypokalemia (< 3.5): GI losses (N/V/D), dehydration, diuretic use, laxative abuse. Digoxin + hypokalemia = high toxicity risk. S/S: Arrhythmias (PVC to V-fib), muscle weakness, paresthesia, fatigue. ECG: Flat T, prominent U, low ST. Treat: PO/IV K+ supplements, K+-rich foods (OJ, banana, potato, spinach). NI: Monitor K+ with diuretics; IV rate < 10 mEq/h.
