When identifying an infiltration at the IV catheter site, what is the first action the nurse should take?

The first action a nurse should take upon identifying an infiltration at the IV catheter site is to stop the infusion. When infiltration occurs, the intravenous fluid and medications leak into the surrounding tissue instead of administering them into the bloodstream. Continuing the infusion can exacerbate the situation, potentially leading to further swelling, discomfort, and damage to the tissue.

Stopping the infusion promptly is crucial to minimize these risks and allows the nurse to assess the situation better and decide on the appropriate interventions, such as removing the catheter, applying compresses, or elevating the extremity, based on the extent of infiltration and the patient's condition. This timely action prioritizes patient safety and helps prevent complications associated with infiltration.
