What is the purpose of placing a small piece of sterile tape across the hub when accessing an IV?

Placing a small piece of sterile tape across the hub when accessing an IV serves the important purpose of temporarily anchoring the catheter during disconnection. This practice helps stabilize the IV catheter to prevent it from moving or slipping out, which could potentially cause dislodgment or bleeding. By securing the catheter in place, it minimizes the risk of complications that could arise from improper handling of the IV line.

This is particularly crucial when a healthcare professional needs to momentarily disconnect the IV for procedures or medication administration, providing a safeguard that maintains the integrity of the IV access site until it is appropriately reconnected or dressed. Additionally, it ensures that the line remains accessible and secure, which is essential for maintaining a smooth flow of therapy.
