If an IV is not infusing after a dressing change, which action is essential to check first?

Checking the tubing for kinking is the essential first action when an IV is not infusing after a dressing change because kinks or bends in the tubing can obstruct the flow of fluid, leading to occlusion. Kinking often occurs during dressing changes when the IV line is manipulated, and it can easily go unnoticed until flow issues arise. Ensuring that the tubing is free from any obstruction is crucial in troubleshooting infusion problems since even minor bends can prevent the IV fluid from reaching the patient.

Once it's confirmed that the tubing is not kinked, further assessments can be made regarding catheter position and line patency. However, addressing the most straightforward and common issue, such as tubing kinking, is important for efficiently resolving the problem before investigating more complex causes.
