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?
"TPN is administered for clients who are unable to absorb nutrients from their intestinal tract."
"Clients who require long-term nutritional support are prescribed TPN."
"I should check the client's gastric residual prior to initiating TPN."
"I should administer TPN intravenously over 6 hr.”
The Correct Answer is A
A. TPN is used for clients who cannot absorb nutrients via the intestinal tract, typically due to issues like severe malabsorption or bowel dysfunction.
B. Long-term nutritional support is typically provided via enteral feeding rather than TPN, unless the client cannot tolerate enteral feeding.
C. Gastric residual is relevant for clients receiving enteral nutrition (not TPN), which involves checking for residuals in the stomach before feeding.
D. TPN should be administered over a longer period (typically 12-24 hours), not 6 hours.
