What should a nurse do when a client reports pain above the IV saline lock catheter site?

When a client reports pain above the IV saline lock catheter site, the most appropriate action for a nurse to take is to remove the IV saline lock. Pain at the site can be indicative of complications such as phlebitis, infiltration, or infection, which can occur if the catheter is improperly placed or if the vein is reactive to the catheter.

Removing the IV saline lock helps to prevent further complications and alleviates the client's discomfort. If pain is present, there may be a need to assess the site for redness, swelling, or other signs of complications, and the nurse must ensure the client's safety and comfort by addressing the problem promptly.

While flushing the IV saline lock might be considered if there are questions about patency, it can exacerbate any underlying issues if the site is already symptomatic. Repositioning the catheter could also lead to further complications and is not a first-line intervention without first removing the source of discomfort. Documenting the client's report is important for medical records and continuity of care, but it should not be the primary action in response to a report of pain, as the immediate concern is to ensure the client's safety and comfort by removing the IV.
