What is the nurse's priority action for a patient with a slowing infusion and signs of phlebitis at the IV site?

The priority action for a patient showing signs of phlebitis at the IV site is to stop the infusion and remove the IV catheter. Phlebitis is characterized by inflammation of a vein, which can occur as a result of irritation from the intravenous catheter or solution. Signs may include redness, swelling, pain, and a slowing infusion rate.

By stopping the infusion, the nurse prevents further irritation and potential complications, such as infection or thrombophlebitis, which can occur if the catheter is left in place. Removing the catheter also allows for the assessment of the site and the identification of any further intervention needed. This action prioritizes patient safety and addresses the immediate concern effectively.

In contrast, while inserting a new IV in the left arm may eventually be necessary, it should only be done after addressing the phlebitis in the current site. Preparing a patient for a PICC line placement may not be appropriate at this moment, as the phlebitis needs to be handled first. Elevating the arm can help reduce swelling but does not address the underlying issue of the IV site irritation and does not prevent further complications. Therefore, stopping the infusion and removing the IV catheter is the most appropriate and critical nursing action in this scenario.
