Which statement about total parenteral nutrition administration is correct?

• A. TPN must be given through a dedicated line
• B. TPN can be infused through any IV line
• C. TPN does not require sterile technique
• D. TPN is routinely piggybacked with other meds

Answer: (A)

Total parenteral nutrition is a hyperosmolar, sterile solution given directly into the bloodstream, so it must be delivered through a dedicated line. Using a line only for TPN minimizes the risk of infection, contamination, and line complications, and it avoids drug-incompatibility issues or precipitation that can occur if other medications share the same lumen. Because TPN is highly concentrated, a central venous access option is preferred to provide adequate blood flow and dilution, and this line is kept free of other medications during the infusion. Sterile technique is essential in preparation and administration, but the key safety factor in this context is a line dedicated solely to TPN.
