Question

Quizplus · Accepted Answer

This patient is taking a potassium-sparing diuretic and is ingesting dietary potassium in salt substitutes. The patient shows signs of hyperkalemia: confusion, shortness of breath, and tingling of the hands and feet. The cardiac effects can be fatal, especially if a patient also is taking digoxin. The most appropriate first action would be to obtain an ECG and serum electrolyte levels to evaluate the extent of the patient's hyperkalemia. The patient does not need increased potassium. Furosemide is a potassium-wasting diuretic and would be helpful. Magnesium sulfate is not indicated. Until the patient's status has been assessed further, intravenous insulin is not indicated.
