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

A. TPN should never be administered at a faster rate to “catch up” if a dose is delayed, as this can cause hyperglycemia, fluid overload, and electrolyte imbalances. Any missed volume should be discussed with the provider for safe adjustments. B. For clients receiving TPN, tubing should be changed every 24 hours to reduce the risk of bacterial contamination and bloodstream infections. This is a critical infection-prevention measure, especially because TPN solutions are rich in glucose and support microbial growth. C. Transparent dressings over central lines are typically changed every 7 days or sooner if soiled or loose, not daily. Daily changes are unnecessary and may increase the risk of catheter site trauma. D. Clients on TPN require frequent monitoring of electrolytes and blood glucose, often daily or every 6–8 hours initially, because TPN can rapidly alter fluid and electrolyte balance. Weekly monitoring is insufficient and unsafe.
