TPN refers to which nutrition method?

• A. Enteral nutrition
• B. IV feeding
• C. Total parenteral nutrition
• D. Oral nutrition

Answer: (C)

TPN stands for Total Parenteral Nutrition, a method of delivering all of a person’s nutritional needs directly into the bloodstream via an intravenous line, bypassing the digestive tract. This is used when the gut cannot be used safely or effectively, such as after certain surgeries or in severe gut dysfunction. It differs from enteral nutrition, which provides nutrients through the gastrointestinal tract (by tube or swallowing), and from oral nutrition, which is eaten. TPN provides complete nutrition, hence “total,” and is typically given through a central venous catheter. While lifesaving in appropriate cases, it carries risks like infection at the access site and metabolic complications, so it requires careful monitoring.
