A client who was admitted yesterday with severe dehydration is reporting pain where a 24 gauge intravenous (IV) catheter with normal saline is infusing at a rate of 150 mL/hour. Which intervention should the nurse implement first?

A) Incorrect- While a second IV site might be considered if the first one is causing significant discomfort, it's not the initial intervention. The nurse should first address the immediate concern of pain. B) Correct- Pain at the IV site during infusion might indicate infiltration or irritation. Stopping the infusion is the most immediate intervention to prevent further discomfort and potential complications like tissue damage. C) Incorrect- While assessing for blood return is important to ensure proper IV placement, it's not the initial intervention for managing pain caused by the infusion. D) Incorrect- Discontinuing the IV might be considered if the pain is severe and unmanageable, but the nurse should initially try to address the discomfort without removing the IV.
