What may be administered alongside TPN, and where should it be attached?

• A. Proteins, above the filter
• B. Lipids, below the filter
• C. Carbohydrates, at the filter
• D. Vitamins, directly into the TPN

Answer: (B)

The administration of lipids alongside Total Parenteral Nutrition (TPN) is appropriate as they provide essential fatty acids and additional calories that TPN alone may not supply. Lipid emulsions are typically infused through the same central venous access device but should be administered below the filter if a filter is used in the TPN line. This is crucial because lipids can clog some filters, which could impede the delivery of nutrients and lead to potential complications. TPN is usually formulated to deliver a precise combination of proteins, carbohydrates, fats, vitamins, and minerals. However, the configuration of the infusion system is essential; administering lipids below the filter ensures the integrity and flow of both TPN and lipid emulsions without obstruction. This practice supports the delivery of the full nutritional regimen needed for patients who depend on TPN for nourishment.
