A woman receiving IV chemotherapy reports burning and pain at the cannula; the area is swollen and pale and the infusion is slow. The drug is a vesicant. What is the first action?

1. Stop and aspirate via the cannula
2. Finish the dose and document
3. Remove the cannula and massage the area
4. Speed up the infusion to finish it

Answer: A) Stop and aspirate via the cannula. Vesicant extravasation is an emergency: stop the infusion, aspirate through the cannula before removing it, follow the protocol (antidote and compresses by drug), and do not massage.
