How should IV potassium be administered?

• A. Must be given in an infusion pump so the rate can be regulated and diluted
• B. Given as a rapid IV push
• C. Administered by gravity drip
• D. Orally

Answer: (D)

IV potassium must be given with an infusion pump and diluted in IV fluid so the dose and rate are precisely controlled. Potassium sharply affects the heart’s electrical activity, so infusing it too quickly can lead to dangerous arrhythmias or cardiac arrest. Giving potassium rapidly by IV push or relying on a gravity drip for rate control is unsafe because it can’t be reliably regulated. For IV replacement, this route is used specifically for IV administration; oral potassium is a separate route and is not how IV potassium is delivered. Always ensure proper dilution, use an appropriate IV access, and monitor the patient closely during administration.
