What does Total Parenteral Nutrition (TPN) primarily provide?

• A. Only protein and electrolytes
• B. Calories, protein, electrolytes, vitamins, minerals, and 20-70% dextrose
• C. Only carbohydrates and fats
• D. Amino acids and lipids only

Answer: (B)

Total Parenteral Nutrition (TPN) is a specialized form of nutrition delivered intravenously, primarily aimed at providing complete nutritional support to patients who are unable to consume food orally or absorb nutrients through the gastrointestinal tract. The correct answer highlights that TPN encompasses a comprehensive range of essential nutrients: it supplies calories in the form of carbohydrates (typically dextrose), proteins as amino acids, and a range of fats (lipids). Additionally, TPN includes vital electrolytes, vitamins, and minerals, which are necessary for maintaining homeostasis and supporting overall health. This multifaceted composition of TPN is particularly critical for patients with specific medical conditions that impair nutrition, ensuring they receive all the necessary macronutrients and micronutrients to promote recovery and prevent deficiencies. Each component of TPN plays a vital role in various bodily functions, making it essential for survival in individuals who cannot take standard dietary intake.
