A nurse notes blanching, coolness, and edema at an IV site. What is the most appropriate action?

• A. Discontinue the IV line
• B. Check for blood return
• C. Apply warm compress
• D. Measure the area of infiltration

Answer: (A)

When you see blanching, cool skin, and swelling at an IV site, that signals infiltration—the IV fluid is leaking into the surrounding tissue instead of staying in the vein. The priority is to stop the ongoing leakage and protect the tissue, so the IV line should be discontinued and the cannula removed right away. After discontinuing, manage the area as needed for comfort and protection, such as elevating the limb and applying an appropriate compress, and place a new IV elsewhere if needed. Document what happened and monitor the site for changes.

Why the other actions aren’t the best immediate move: checking for blood return doesn’t address the tissue injury already occurring and can be unreliable in an infiltrated site; applying a warm compress could worsen tissue swelling early on, whereas cold is typically preferred to reduce edema; simply measuring the area doesn’t stop the infiltration or prevent further damage.
