How often should a nurse change the intravenous (IV) site?

The recommended frequency for changing the intravenous (IV) site is typically every 72 to 96 hours. This guideline is based on research and evidence aimed at minimizing the risk of infection and ensuring optimal patency of the IV line. Changing the IV site within this timeframe helps reduce the likelihood of complications such as phlebitis or infiltration while allowing sufficient time for the vein to recover if another IV insertion is needed.

Other options may suggest changing the site more frequently than necessary, which could increase discomfort for the patient and lead to unnecessary interventions. Conversely, changing the site less frequently than the recommended timeframe may raise the risk of complications, ensuring that patients receive the best standard of care is key.
