A nurse is teaching a client who has a new prescription for total parenteral nutrition through a central line. Which of the following information should the nurse include in the teaching?

A is incorrect because IV tubing for total parenteral nutrition should be changed every 24 hours to prevent infection. B is incorrect because abdominal distention is not an expected effect of total parenteral nutrition. It could indicate a complication such as fluid overload or bowel obstruction. C is incorrect because gastric residual is not relevant for total parenteral nutrition, which bypasses the gastrointestinal tract. D is correct because weight measurement is an important indicator of fluid balance and nutritional status for clients receiving total parenteral nutrition.
