A client receiving an intravenous infusion of vincristine reports severe pain and burning at the peripheral intravenous site. The nurse observes swelling and blanching around the insertion site. Arrange the following nursing actions in the correct sequence.
- 1Stop the continuous intravenous infusion of vincristine immediately.
- 2Disconnect the intravenous tubing and aspirate residual medication from the catheter.
- 3Remove the peripheral intravenous catheter.
- 4Administer subcutaneous hyaluronidase around the extravasation site as prescribed.
- 5Apply a warm compress to the affected area and elevate the extremity.
Cevap
The correct sequence for managing a vincristine extravasation is to first stop the infusion, then aspirate the residual drug, remove the intravenous catheter, administer the subcutaneous antidote (hyaluronidase), and finally apply a warm compress and elevate the affected extremity.
Managing a vesicant extravasation requires a prioritized, protocol-driven approach to minimize severe tissue necrosis. The infusion must be stopped immediately as the absolute first action to halt further exposure. Leaving the catheter in place temporarily allows the nurse to aspirate any residual drug from the catheter and the immediate subcutaneous pocket. Once aspirated, the catheter is removed. For vinca alkaloids like vincristine, the specific antidote (hyaluronidase) is injected subcutaneously around the site to break down connective tissue. Finally, warm compresses are applied—a unique requirement for vinca alkaloids—to induce vasodilation, which helps disperse the drug systemically and reduces local tissue damage. Elevation helps to reduce edema.
