Total Parenteral Nutrition (TPN) is defined as nutrients delivered through which route?

Total parenteral nutrition delivers nutrients directly into the bloodstream through an intravenous route, typically via a central venous catheter. This method bypasses the gastrointestinal tract entirely, which is essential when the gut cannot be used or adequately absorbed for nutrition. The nutrition formula includes amino acids, glucose, lipids, vitamins, minerals, and trace elements to meet metabolic needs.

Oral and nasogastric tube feeding involve the gastrointestinal tract (enteral nutrition), not TPN, so they don’t fit. Rectal administration is not a reliable or standard route for complete nutrition and cannot provide all nutrients in the required amounts.
