Hypokalemia can predispose the patient to life-threatening dysrhythmias (e.g.,premature ventricular contractions)and potentiate the actions of digoxin. Hypokalemia also increases the risk for digoxin toxicity,which can also cause life-threatening dysrhythmias. The other data indicate that the patient's heart failure requires more effective therapies,but they do not require nursing action as rapidly as the low serum potassium level.
