A patient receiving IV potassium chloride has a prescription for replacement of hypokalaemia. Which action is safest?
Correct answer: B. Administer it diluted through an infusion pump
- A. Give it by rapid IV push
- B. Administer it diluted through an infusion pump
- C. Mix it with blood in the same tubing
- D. Give it undiluted through a small vein
Explanation
IV potassium chloride must be diluted and administered at a controlled rate using an infusion pump because rapid administration can cause fatal cardiac arrhythmias. It must never be given by IV push or mixed with blood in the same tubing.
