What should the nurse do if a client's IV site displays tenderness, erythema, warmth, and mild edema?

When a client's IV site shows signs of tenderness, erythema, warmth, and mild edema, it indicates potential complications such as phlebitis or infiltration. Changing the IV site is the most appropriate action because it addresses the underlying issue directly.

Moving the IV to a different site will reduce further irritation or damage to the current site, allowing for better circulation and reducing the risk of potential complications like infection. This proactive approach helps ensure safe and effective administration of IV therapy, minimizing discomfort for the client.

Other options, while they may provide temporary relief or treatment, do not address the root cause of the symptoms. For instance, irrigating the IV tubing could potentially exacerbate the issue if infiltration is occurring. Slowing the rate of infusion might relieve discomfort temporarily, but it does not resolve the problem. Obtaining a prescription for analgesics could help manage pain, but it does not address the need to ensure proper IV therapy delivery and site integrity. The best practice in this scenario is to remove the affected IV and establish a new site for infusion.
