Which replacement method requires cardiac monitoring during administration?

• A. Oral potassium chloride
• B. IV push potassium chloride
• C. IV potassium infusion with continuous ECG monitoring
• D. Intramuscular potassium chloride

Answer: (C)

Potassium replacement must be given with careful heart monitoring because the heart’s rhythm is highly sensitive to potassium levels. Administering potassium intravenously as an infusion with continuous ECG monitoring allows clinicians to watch for any changes in cardiac rhythm as the potassium level rises. If the ECG shows signs of hyperkalemia or other conduction abnormalities, the infusion can be slowed or stopped immediately to prevent dangerous arrhythmias or cardiac arrest. Oral potassium is absorbed slowly and generally doesn’t require heart monitoring, so continuous ECG isn’t necessary. IV push potassium delivers a rapid bolus that can precipitate life-threatening arrhythmias if not controlled, making continuous monitoring essential but with a method that isn’t used this way. Intramuscular potassium chloride is not used because it can cause tissue damage and unreliable absorption.
