Lasix is a nonpotassium-sparing diuretic. Without a potassium supplement the client may be-come hypokalemic. Hypokalemia increases the risk for digoxin toxicity. Both hypokalemia and digoxin toxicity can cause cardiac dysrhythmias. Clients with hypokalemia from diuretic use may experience intestinal distention and decreased bowel sounds. Severe diarrhea may be a cause of hypokalemia, not a result of hypokalemia. Clients with hyperactive reflexes may have hy-pocalcemia. Lasix and digoxin do not predispose a client to hypocalcemia. Peripheral cyanosis is not a potential problem related to the client's medication regimen.
