What does PN stand for in the context of nutrition support?

• A. Partial Nutrition
• B. Pulmonary Nutrition
• C. Parenteral Nutrition
• D. Peripheral Nutrition

Answer: (C)

Parenteral Nutrition delivers nutrients directly into the bloodstream via an intravenous line, bypassing the gastrointestinal tract. This approach is used when the gut cannot be used or cannot absorb nutrients—for example after certain abdominal surgeries, severe bowel dysfunction, obstruction, or pancreatitis with bowel rest. It’s typically given through a central venous catheter (central PN) and includes amino acids, glucose, lipids, electrolytes, vitamins, and trace elements. This is distinct from feeding that uses the GI tract (enteral nutrition). The other terms aren’t standard ways to denote PN in clinical nutrition practice.
