A patient receiving intravenous calcium develops pain, swelling and blanching around the cannula. What should the nurse do first?
Correct answer: B. Stop the infusion and assess the site
- A. Slow the infusion and continue observing
- B. Stop the infusion and assess the site
- C. Flush rapidly with normal saline
- D. Apply pressure and restart at the same site
Explanation
Calcium can cause serious tissue injury if it extravasates, so the infusion must be stopped immediately and the site assessed. Continuing or forcefully flushing the infusion can spread the medication into surrounding tissue.
