Which statement correctly describes a safety practice when administering TPN via a central line?

• A. Check the solution for cloudiness or turbidity
• B. Thread the IV tubing through an infusion pump
• C. Use aseptic technique when handling the injection cap
• D. Connect the tubing to the central line

Answer: (C)

Aseptic technique during any moment you access a central-line port is essential to prevent infection. When administering TPN through a central line, the injection cap or port is the access point where contaminants can be introduced. Keeping that access sterile — performing hand hygiene, cleaning the cap with an appropriate antiseptic, and using sterile equipment to puncture or connect — minimizes the risk of a catheter-related bloodstream infection. TPN provides a nutrient-rich environment, so even a small lapse in sterility at the access point can lead to serious infection quickly. While other safety steps, like inspecting the solution for cloudiness or ensuring the tubing is properly set up, are important, the most critical practice in this scenario is maintaining aseptic technique at the injection cap to protect the patient from infection.
