Which statement correctly describes the safe administration of IV potassium?

• A. It should be diluted and given via infusion pump
• B. It should be given undiluted as a rapid bolus
• C. It should be given by gravity drip without dilution
• D. It should be given orally

Answer: (A)

Potassium chloride given IV must be handled with extreme care because it can affect the heart if it enters too quickly or in too concentrated a form. Diluting the solution and delivering it through an infusion pump provides precise control of both how concentrated it is and how fast it is delivered, which helps prevent dangerous hyperkalemia and vein irritation. Administering it undiluted as a rapid bolus or using a gravity drip without a pump removes this control and can lead to life-threatening cardiac events or tissue damage. Oral potassium is a different route entirely and does not address IV safety. So, dilute and administer via infusion pump to ensure a slow, controlled IV delivery while monitoring the patient’s rhythm and potassium level.
