What should be the first action taken when redness, swelling, drainage, and pain are noted at a peripheral IV site?

When redness, swelling, drainage, and pain are observed at a peripheral IV site, the most appropriate first action is to discontinue the IV infusion and remove the catheter. This is essential because these symptoms indicate a possible infection or phlebitis, which can lead to complications if the IV is left in place. Removing the catheter helps prevent further irritation or infection and allows for proper evaluation and treatment of the site.

In this situation, the primary goal is to protect the patient. Continuing with the infusion or attempting to clean or treat the site without removing the source of irritation could exacerbate the condition and potentially lead to systemic infection. By taking the correct action to discontinue the infusion and remove the catheter, the healthcare provider can also initiate the necessary assessment and interventions to promote healing and manage any complications associated with the symptoms observed.
