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?

A. “You require TPN because you have a low platelet count” is incorrect. TPN is not prescribed for low platelet counts; it is used for nutritional support. B. “You will receive TPN through a central vein” is correct. TPN is typically administered through a central venous catheter because it is a hypertonic solution that can irritate peripheral veins. C. “You require TPN because your glucose is too high” is incorrect. TPN is not used to manage high glucose levels; it is used for providing nutrition when oral or enteral feeding is not possible. D. “You will receive TPN for the next 6 months” is incorrect. The duration of TPN therapy varies depending on the client’s condition and nutritional needs.
