A nurse is caring for a client who is receiving total parenteral nutrition (TPN). Which of the following actions should the nurse take to prevent adverse effects?

A. Monitoring weight weekly is important for tracking nutritional status but does not directly prevent adverse effects of TPN. B. Performing blood glucose monitoring hourly is excessive unless the client has a significant issue with blood glucose control. C. Changing the IV dressing every 96 hours is too long; the dressing should be changed every 48–72 hours to prevent infection. D. Changing the IV tubing every 24 hours is correct to reduce the risk of infection and contamination in TPN administration.
