A nurse is assessing a client's IV infusion site and notes that the site is cool and edematous. Which of the following actions should the nurse take

A. Slow the IV solution rate: If the IV site is cool and edematous, it suggests infiltration or extravasation, not a simple issue of excessive flow rate. The coolness is due to the temperature of the IV fluid, and the edema is caused by the fluid accumulation in the tissues. Slowing the infusion won't resolve the problem; it could actually delay addressing the underlying issue. B. Apply a warm, moist compress: Warm compresses can be helpful for resolving issues like phlebitis or superficial thrombophlebitis, but for infiltration, it's better to stop the infusion and address the IV placement immediately. Heat is not indicated until after confirming the type of issue. C. Maintain the extremity below the level of the heart: Elevating the extremity is generally recommended to help reduce edema associated with infiltration, but it does not address the fact that the IV is no longer patent and needs to be restarted. D. Initiate a new IV distal to the initial site: If infiltration is suspected, the IV should be discontinued at the current site, and a new IV should be initiated in a different location, preferably distal to the previous site. This prevents further damage to tissues and ensures the IV therapy continues.
