When dealing with extravasation, what is the first step in management?

1. Call for surgical consult

2. Immediate discontinuation of infusion

3. Apply heat to the area

4. Elevate the affected limb

The correct answer is: Immediate discontinuation of infusion

The first step in managing extravasation is immediate discontinuation of the infusion. This action is crucial because continuing the infusion may exacerbate tissue damage by allowing more of the irritant or vesicant solution to disperse into the surrounding tissue. Stopping the infusion promptly limits the extent of injury and is essential to initiating further management steps. Following discontinuation, other interventions—such as calling for a surgical consult if warranted, applying heat or cold therapy, or elevating the affected limb—may be considered based on the specifics of the situation and the nature of the extravasated substance. However, the priority remains clear: the infusion should be stopped immediately to protect the affected tissue and mitigate further risk.
