Which components are included in total parenteral nutrition delivered via a PICC line?

• A. Carbohydrates and lipids only
• B. Blood products and electrolytes only
• C. Protein, electrolytes, vitamins, trace elements, and fat emulsion
• D. Water and electrolytes only

Answer: (C)

Total parenteral nutrition given through a PICC line provides all nutrients the body needs through an IV when the gut can’t be used. A TPN solution includes macronutrients for energy and growth—amino acids for protein, carbohydrates for energy, and fats as fat emulsion—as well as micronutrients such as electrolytes, vitamins, and trace elements. The option that lists protein, electrolytes, vitamins, trace elements, and fat emulsion best reflects the key components required to meet these nutritional needs. Carbohydrates are typically included as part of TPN as well, but the categories shown cover the essential nutrient groups beyond carbohydrate, making this choice the most complete representation among the options. The other choices are incomplete or inaccurate: one is limited to carbs and lipids, another references blood products, and another limits components to water and electrolytes only.
