A nurse is observing a newly licensed nurse who is administering total parenteral nutrition (TPN) to a client. Which of the following actions by the newly licensed nurse indicates a need for the nurse to intervene?

Rationale: A. If TPN is interrupted or the next bag is not immediately available, the nurse should infuse a dextrose solution (such as D10W) to prevent hypoglycemia. Abrupt discontinuation of TPN can cause a rapid drop in blood glucose because the client has been receiving a high glucose load continuously. B. Transparent semipermeable dressings over a central venous catheter site are typically changed every 5–7 days, or sooner if they become loose, damp, or soiled, to reduce infection risk. C. TPN tubing is usually changed every 24 hours due to the high dextrose content, which increases the risk of bacterial growth and infection. This practice helps maintain sterile technique and prevent catheter-related bloodstream infections. D. This indicates a need for intervention. Central venous catheters used for TPN should never be flushed with small syringes (such as 5 mL) because they generate excessive pressure that can damage the catheter and potentially rupture it. The nurse should use a 10 mL syringe or larger when flushing to ensure safe pressure levels and catheter integrity.
