Practice Question
A nurse needs to change the IV tubing for a client receiving peripheral IV therapy. What is the correct procedure for this task?
Answer Choices:
Correct Answer:
Clamp the IV tubing, remove the old tubing, attach the new tubing, and unclamp
Rationale:
🔶 Clamping prevents air from entering the line, which is essential to prevent air embolism and accidental free-flow of IV fluid.
🔶 Removing the old tubing first maintains control of the line and avoids contamination.
🔶 Attaching new tubing while the line is still clamped ensures proper priming and sterility before infusion resumes.
🔶 Unclamping at the end re-establishes fluid flow safely after the system is secured.
🔶 This sequence supports aseptic technique, patient safety, and correct pressure management.
Incorrect Options
Attach the new tubing, clamp the IV line, and remove the old tubing
🔶 This exposes the tubing end to air before clamping, increasing embolism risk.
🔶 It also risks accidental leakage or contamination.
Unclamp the IV tubing, attach the new tubing, and remove the old tubing
🔶 Leaving the line unclamped during manipulation is unsafe and may cause uncontrolled fluid flow.
🔶 This violates safe IV-changing protocols.
Remove the old tubing, attach the new tubing, and unclamp the IV line
🔶 Removing the old tubing without clamping first risks air entry and leakage.
🔶 Sequence fails to prioritize patient safety.
