A charge nurse is educating a newly licensed nurse about total parenteral nutrition (TPN) therapy. Which of the following statements indicates an understanding of the teaching?

A. "I should check the client's gastric residual prior to initiating TPN.": Gastric residual monitoring applies to enteral nutrition, not parenteral. TPN bypasses the gastrointestinal tract entirely, so gastric residual checks are unnecessary. B. "Clients who require long-term nutritional support are prescribed TPN.": Long-term nutrition is often managed with enteral feeding when possible. TPN is reserved for clients who cannot use their GI tract due to conditions like bowel obstruction or severe malabsorption. C. "I should administer TPN intravenously over 6 hr.": TPN is infused continuously over 24 hours using an infusion pump to maintain stable glucose levels and prevent complications such as hypoglycemia or osmotic diuresis. A 6-hour infusion is unsafe. D. "TPN is administered for clients who are unable to absorb nutrients from their intestinal tract.": This statement is accurate. TPN provides essential nutrients intravenously for clients with nonfunctional or severely impaired GI tracts, ensuring adequate nutrition and metabolic support.
