A nurse is caring for a client who is receiving a continuous IV infusion. The nurse notes that the skin around the catheter's insertion site is edematous and cool. Which of the following actions should the nurse take first?

Choice A Reason: Documenting the infiltration is important for the client's medical record, but it should not be the first action when infiltration is suspected. Choice B Reason: Elevating the arm can help reduce swelling, but it should come after stopping the infusion. Choice C Reason: Applying a warm compress can help with comfort and may be done after stopping the infusion, but it is not the first action. Choice D Reason: Stop the infusion is correct. When a nurse observes signs of infiltration around an IV insertion site, such as edema and coolness of the skin, the first and most important action is to stop the infusion immediately. Infiltration occurs when the IV fluid leaks into the surrounding tissue instead of going into the vein. Stopping the infusion prevents further damage to the surrounding tissue and minimizes the risk of complications.
