Which statement describes the appropriate administration of potassium in hypokalemia?

• A. Administer IV potassium push when available
• B. Administer IV potassium via rapid bolus
• C. Administer oral potassium only
• D. Administer IV potassium via piggyback infusion with continuous ECG monitoring

Answer: (D)

Potassium replacement must be given in a controlled, monitored way because rapid changes in serum potassium can trigger dangerous heart rhythms. Intravenous potassium should never be given as a push or a rapid bolus; concentrated potassium solutions can cause vein irritation and may lead to life-threatening arrhythmias if given too quickly. Oral potassium can be used for mild deficits, but in more significant hypokalemia or when oral therapy isn’t feasible, IV replacement is necessary. The safest and most reliable method is IV potassium delivered via a piggyback infusion with continuous ECG monitoring. This setup allows a slow, controlled rate through an IV pump, with ongoing observation for any arrhythmias and frequent reassessment of potassium levels to avoid both under-treatment and overcorrection.
