What is the most important priority nursing action after stopping the infusion of a vesicant intravenous solution?

The most important priority nursing action after stopping the infusion of a vesicant intravenous solution is to aspirate the catheter. This action is crucial because vesicants can cause severe tissue damage if they infiltrate the surrounding tissue. By aspirating the catheter, the nurse assesses the patency of the catheter and helps ensure that no residual vesicant remains in the intravenous line or has escaped into the surrounding tissue.

This step is essential for preventing further damage and allows for the possibility of administering any necessary antidotes if the vesicant has infiltrated. The prompt action of aspirating can help determine if the IV line is still patent or if the vesicant has already caused complications, aiding in timely intervention.

Other actions may also be important, but they follow the assessment of the catheter patency. For instance, elevating the affected limb can help reduce swelling and discomfort, while applying a warm compress might alleviate pain, and notifying the physician is necessary for further management. However, the priority is to address the immediate risk of the vesicant by ensuring that the IV line is clear of the harmful solution, which is why aspirating is the critical first nursing action.
