Correct Answer: A

Rationale: The correct answer is A - Central venous access device. TPN is a highly concentrated solution that can cause damage to peripheral veins, so it needs to be administered through a central line to prevent irritation and potential complications. Central venous access devices provide direct access to the central circulation, allowing for the infusion of TPN into larger, high-flow veins. This route ensures a rapid and uniform distribution of nutrients throughout the body.

B: Midline catheter is not suitable for TPN administration as it may cause irritation and phlebitis due to the high osmolarity of TPN.
C: Subcutaneous route is not appropriate for TPN as it cannot provide the necessary infusion rate and volume.
D: Intraosseous route is not recommended for TPN administration due to the risk of complications and limited capacity for infusion.
