What should the nurse do if a client reports pain after an IV catheter insertion?

When a client reports pain after an IV catheter insertion, it is crucial to assess the situation carefully. If pain is significant, it may indicate several potential issues, such as improper placement of the catheter, irritation of the vein, or even an infection. In this context, removing the catheter and inserting a new one in a different site is the most appropriate action. This approach not only addresses the immediate pain and discomfort the client is feeling but also helps to prevent complications related to the existing catheter.

In contrast, massaging the site might exacerbate potential complications, such as inflammation or irritation. Asking the client to simply tolerate the discomfort fails to address the underlying issue and may lead to further complications or dissatisfaction with care. Applying a warm compress could provide temporary comfort, but it does not resolve the source of the pain or address any possible complications from the catheter insertion. Therefore, the correct choice prioritizes patient comfort and safety by addressing the situation directly through the removal and replacement of the catheter.
