Obtain a basic metabolic profile. Measure electrolytes, blood urea nitrogen (BUN), and creatinine. Including the glucose, calcium, and/or phosphorus level is indicated if coexistent electrolyte disturbances are suspected. Consider a digoxin level if the patient is on a digitalis preparation, as hypokalemia can potentiate digitalis-induced arrhythmias.
