A. Total parenteral nutrition (TPN). B. Nasogastric. C. Parenteral. D. Enteral.

Correct Answer is D

Explanation

Choice A rationale:
Total parenteral nutrition (TPN) is a method of feeding that bypasses the gastrointestinal tract. It’s not the same as a feeding ostomy.
Choice B rationale:
Nasogastric refers to a tube that is placed through the nose into the stomach. It’s not a term for a feeding method.
Choice C rationale:
Parenteral refers to routes of administration that are not oral or enteral, such as intravenous. It’s not the same as a feeding ostomy.
Choice D rationale:
Enteral feeding is the correct term for feeding a patient through a feeding ostomy. It involves delivering nutrition directly to the stomach or small intestine.
