Question 1 of 5
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: B
Rationale: The correct answer is B: Central venous access device. TPN is a hypertonic solution that requires a large vein for administration to prevent phlebitis and irritation. Central venous access devices provide direct access to the central circulation, reducing the risk of complications like phlebitis and extravasation. Midline catheters (
A) have a higher risk of phlebitis and may not be suitable for TPN administration. Subcutaneous (
C) and intraosseous (
D) routes are not appropriate for TPN administration due to limited absorption and potential complications.
