A nurse is caring for a client who has a prescription for total parenteral nutrition (TPN). Which of the following routes of administration should the nurse use?

  • A. Subcutaneous
  • B. Intravenous
  • C. Central venous access device
  • D. Midline catheter
Correct Answer: C

Rationale: The correct answer is C: Central venous access device. TPN is a highly concentrated solution that provides all the nutrients a person needs intravenously. A central venous access device allows for the infusion of TPN into a large central vein, such as the superior vena cava, ensuring immediate access to the bloodstream for rapid absorption. Using other routes like subcutaneous (A), intravenous (B), or midline catheter (D) may not be suitable due to the high osmolarity of TPN, which can cause irritation and damage to smaller veins. Therefore, a central venous access device is the most appropriate and safe route for administering TPN.
