Step 1: Understanding the Question:
The question asks for the medical term that describes the method of feeding a patient by infusing liquid nutrients directly into their bloodstream.
Step 2: Detailed Explanation:
In clinical nutrition, when a patient cannot consume normal food, alternative feeding methods are used:
Enteral Nutrition: This refers to nutrition delivered through the gastrointestinal (GI) tract. It involves using a feeding tube (like a nasogastric tube) that goes directly into the stomach or intestines.
Parenteral Nutrition: The prefix "para" means 'outside' or 'beside', and "enteral" refers to the intestines. Therefore, parenteral nutrition completely bypasses the digestive system. A liquid mixture containing basic nutrients (glucose, amino acids, lipids, vitamins, minerals) is administered directly into a vein (intravenously). This is used when a patient's GI tract is non-functional or needs complete rest.
Liquid / Therapeutic Diets: These refer to the consistency or nutritional profile of food consumed normally through the mouth.
Step 3: Final Answer:
Feeding administered directly into the veins is known as Parenteral Nutrition.
