Intravenous (IV) Therapy Practice Exam 2026 - Free IV Therapy Practice Questions and Study Guide

Changing the IV site dressing every 48 to 72 hours is the standard practice recommended to maintain proper hygiene and minimize the risk of infection. This interval allows for adequate monitoring of the site for signs of complications, such as infiltration or phlebitis, while also ensuring that the dressing is secure and that the insertion site is protected from contaminants. Regular dressing changes help maintain aseptic conditions and promote healing, especially when the IV is in place for an extended period. Keeping a consistent schedule within this timeframe is essential for patient safety and the effectiveness of IV therapy.
