Which action reduces the risk of vein irritation when administering potassium chloride?

• A. Using a CVAD for large doses
• B. Increasing the IV rate
• C. Giving IM injections
• D. Infusing through a peripheral line only

Answer: (B)

Potassium chloride can irritate and even injure veins if it is given too quickly or in a concentrated form. To reduce this irritation, it’s best to deliver potassium chloride through central venous access when large doses are needed, because central veins have higher flow and tolerate the solution better than small peripheral veins. Diluting the medication and infusing it slowly according to the order also helps protect the vein lining from damage. IM injections are not appropriate for potassium chloride and can cause tissue injury, and relying on a peripheral line for large doses increases, not decreases, vein irritation. So the protective approach is using central venous access for large doses and ensuring slow, diluted IV administration.
