What is the best nursing intervention for a client experiencing acute pain at an IV site?

The most appropriate nursing intervention for a client experiencing acute pain at an IV site is to evaluate the IV site for signs of complications. This is essential because pain at an IV site could indicate various issues, such as phlebitis, infiltration, or an infection. By assessing the site, the nurse can determine the underlying cause of the pain and decide on the necessary actions to address it, such as discontinuing the IV, applying warm or cold compresses, or notifying the physician for further intervention.

Assessing the site allows for timely identification of serious complications that may require immediate treatment, ensuring the client's safety and comfort. Proper evaluation also sets the foundation for documenting any findings and can guide further management of the IV therapy. In contrast, increasing the flow rate could exacerbate pain if complications are present, documentation is important but merely a record rather than an immediate intervention, and asking the client to describe the pain intensity provides subjective data but does not address the potential physical complications that need to be evaluated.
