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?

A. Plans for a check of the client's fingerstick glucose level every 6 hr: Monitoring blood glucose levels is essential for clients receiving TPN due to the risk of hyperglycemia. Checking glucose every 6 hours is a standard practice that helps ensure appropriate glycemic control, so this action is appropriate. B. Schedules a bag and tubing change for 24 hr after the start of the infusion: It is standard practice to change the TPN bag and tubing every 24 hours to reduce the risk of infection and maintain sterility. This timing aligns with best practices for TPN administration, indicating no need for intervention. C. Uses the TPN IV tubing to administer the client's next dose of antibiotics: Using the TPN line for additional medications, such as antibiotics, can lead to complications like incompatible drug interactions or infection. TPN should ideally be delivered through a dedicated line to prevent these risks, which necessitates intervention from the supervising nurse. D. Gradually increases the TPN infusion rate each hour until the prescribed rate is achieved: Gradual escalation of the TPN infusion rate is important to prevent complications such as hyperglycemia. This action is appropriate, as it allows the body to adapt to the increased caloric intake safely.
