What is the primary nursing intervention for a patient experiencing phlebitis?

Removing the IV catheter and applying warm compresses is the appropriate primary nursing intervention for a patient experiencing phlebitis. Phlebitis is characterized by inflammation of the vein, often accompanied by pain, redness, and swelling at the site of the IV placement.

Applying warm compresses can help to increase blood flow to the affected area, which may alleviate discomfort and promote healing. Warmth can also assist in calming any inflammation present in the vein, making it an effective method for managing the symptoms of phlebitis.

Additionally, removing the IV catheter is essential to prevent further irritation and potential complications, such as thrombophlebitis. It's important to discontinue the use of the IV in the affected vein to reduce the risk of worsening the inflammation or causing infection.

In contrast, applying cold compresses is more suitable for conditions involving swelling or bruising but may not be effective for phlebitis, which requires increased circulation to help resolve inflammation. Increasing the IV flow rate could exacerbate irritation in an already inflamed vein and is not a recommended course of action in this scenario. Administering an analgesic may address pain but does not address the underlying issue of phlebitis itself, which should be prioritized.
