A nurse is caring for a client who has a prescription for total parental nutrition (TPN). Which of the following routes of administration should the nurse use?
Correct answer
D
Rationale
The correct answer is D, central venous access device, for TPN administration. Central venous access devices provide direct access to the central circulation, allowing for the infusion of hypertonic solutions like TPN without causing irritation to peripheral veins. Subcutaneous (A) and intraosseous (B) routes are not appropriate for TPN due to the large volume and hypertonic nature of the solution. Midline catheters (C) have a limited dwell time and are not suitable for long-term TPN administration. Therefore, the central venous access device is the most appropriate route for TPN administration.
