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

A) Document the infiltration: While documentation is an important part of the nursing process, it is not the first action to take. If an infiltration is suspected, the priority is to stop the infusion immediately to prevent further harm or fluid leakage into the surrounding tissues. Once the infusion is stopped, the nurse can then document the infiltration for medical record purposes. B) Elevate the arm: Elevating the arm can help reduce swelling, but this should not be the first step. The first priority when infiltration is suspected is to stop the infusion, as continuing it can worsen the tissue damage and swelling. After stopping the infusion, elevating the arm may be considered as part of the subsequent management of the infiltration. C) Apply a warm compress: A warm compress may be helpful after stopping the infusion, particularly if the infiltration involves non-vesicant fluids. However, applying a warm compress is not the immediate action. The first step should be stopping the infusion to prevent any further fluid from infiltrating the tissues. D) Stop the infusion: The most immediate and appropriate action when infiltration is noted around the IV insertion site is to stop the infusion. This prevents additional fluid from leaking into the surrounding tissues, which could cause further damage. Once the infusion is stopped, the nurse can take other steps to manage the infiltration, such as assessing the site, applying a warm compress, or notifying the healthcare provider.
