A serum potassium level of 3.2 mEq/L (3.2 mmol/L) is reported for a patient with cirrhosis who has scheduled doses of spironolactone (Aldactone) and furosemide (Lasix) due. Which action should the nurse take?

A serum potassium level of 3.2 mEq/L is low (hypokalemia), which can be concerning in a patient with cirrhosis who is already at risk for electrolyte imbalances. Spironolactone is a potassium-sparing diuretic that can help increase the patient's potassium level and correct the hypokalemia. Therefore, the appropriate action for the nurse to take in this scenario is to administer the spironolactone. Withholding the spironolactone could further lower the potassium level. Furosemide, on the other hand, is a loop diuretic that can lead to potassium loss and worsen hypokalemia; hence, it should be withheld until the nurse discusses the situation with the healthcare provider. While the healthcare provider should be informed about the low potassium value, immediate administration of spironolactone is necessary to address the hypokalemia in this patient population.
