What is the first action a nurse should take if there is suspicion of an intravenous vesicant extravasating?

When there is a suspicion of an intravenous vesicant extravasating, the initial and most critical action is to stop the infusion. This step is essential because vesicants can cause significant tissue damage if they leak into the surrounding skin and subcutaneous tissue. By halting the infusion right away, the nurse can minimize the amount of the harmful agent that is exposed to the tissues and potentially reduce the extent of injury.

After stopping the infusion, the nurse would typically follow up with other actions such as notifying the healthcare provider and assessing the site, but stopping the infusion is the most urgent response to prevent further complications. Taking immediate action to stop the delivery of the vesicant is paramount in managing the situation and ensuring patient safety.
