CNJNE IVE Adult IV therapy Practice Test

When extravasation is suspected, the most appropriate immediate action is to remove the IV line and elevate the limb. This response is essential because extravasation refers to the leakage of intravenous fluid into the surrounding tissue, which can cause swelling and damage to the tissues. By removing the IV line, you stop the infusion of any harmful medication into the tissue. Elevating the limb can help reduce swelling by reducing blood flow to the affected area, promoting drainage, and mitigating discomfort.

Addressing extravasation promptly is critical to preventing further damage, and while other actions might be necessary afterward (such as applying compresses or notifying a physician), the primary goal is to stop the extravasation process first. This initial response is crucial to minimize injury and complications associated with local tissue damage resulting from the extravasation.
