Which action is not a recommended practice when administering IV medications?

• A. Verify compatibility with MAR and order.
• B. Administer via infusion pump.
• C. Use appropriate IV access.
• D. Push potassium or other vesicants rapidly.

Answer: (D)

Safe IV medication administration hinges on controlling the rate, dilution, and site to prevent harm. Pushing potassium or other vesicants rapidly is not recommended because potassium chloride, even when diluted, can cause life‑threatening cardiac arrhythmias if given too quickly. It must be delivered at a prescribed, slow rate through a regulated infusion—often via an infusion pump or IV piggyback—and with appropriate dilution and monitoring. Verifying compatibility with the MAR and order helps ensure the right drug and dose are given, using the infusion pump maintains precise control over the rate, and selecting appropriate IV access reduces complications like infiltration or phlebitis. In short, rapid IV push of potassium or vesicants can cause serious harm, so controlled, prescribed administration is essential.
