A nurse is providing teaching to a client who has a prescription for total parenteral nutrition (TPN). Which of the following information should the nurse include in the teaching?

C. PN solutions are highly concentrated and can cause phlebitis if administered through peripheral veins. A central line (e.g., central venous catheter) provides a larger, more durable access point for administering TPN safely and effectively. A. TPN solutions typically include glucose to meet the body's energy needs. Regular monitoring of blood sugar levels helps to prevent hyperglycemia or hypoglycemia, which are potential complications of TPN administration. However, the monitoring should be more frequent. B. Weight monitoring helps evaluate fluid status, nutritional adequacy, and overall response to TPN therapy. Changes in weight can indicate fluid retention or loss and guide adjustments in the TPN formula. It should be done daily. D. TPN can affect fluid balance, and monitoring I&O allows healthcare providers to detect fluid retention or deficit early. It helps ensure that the client's fluid status remains stable during TPN administration. The monitoring should be done everyday.
