What does TPN stand for?

• A. Total Parenteral Nutrition
• B. Total Parenteral Nourishment
• C. Total Peripheral Nutrition
• D. Total Peroral Nutrition

Answer: (A)

Total Parenteral Nutrition means providing all the essential nutrients through an IV, bypassing the digestive tract. This method is used when the gut can’t absorb nutrients or a person can’t eat or keep food down. The word “Total” signals that it supplies all daily calories and nutrients, “Parenteral” means the nutrients enter the bloodstream directly (not via the GI tract), and “Nutrition” covers the full spectrum of nutrients—carbohydrates for energy, amino acids for protein, fats, fluids, electrolytes, vitamins, and minerals. Because the solution is concentrated, it’s usually given through a central venous catheter to protect vein integrity and support long-term use, with careful monitoring for glucose levels, electrolytes, liver function, and infection risk. The other terms aren’t standard for this method: nourishment isn’t the established term, peroral refers to eating by mouth, and peripheral nutrition would imply a different, less common approach.
