Emergency Medical Technician (EMT) Intermediate Practice Exam

When discontinuing an IV line, you should FIRST:

1. Attach a new IV line

2. Shut off the flow from the IV with the roller clamp

3. Remove the IV catheter immediately

4. Flush the IV line

The correct answer is: Shut off the flow from the IV with the roller clamp

When discontinuing an IV line, the first step should be to shut off the flow from the IV using the roller clamp. This action is critical because it prevents any additional fluid from entering the patient's bloodstream, which could lead to complications such as fluid overload or accidental infusion of medications already administered. Once the flow is stopped, appropriate measures can be taken to safely withdraw the catheter and manage the site of insertion. Properly stopping the infusion also helps control any potential bleeding or fluid leakage that might occur during the disconnection process, ensuring patient safety and maintaining sterile technique. Choosing to attach a new IV line before stopping the flow would be premature and could result in confusion or complications. Removing the catheter immediately without first shutting off the fluid can lead to unwanted fluid flow, and flushing the line prior to stopping the flow does not align with standard practice for discontinuation of IV therapy.
