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?
Central venous access device
Midline catheter
Subcutaneous
Intraosseous
The Correct Answer is A
Choice A rationale:
Total parental nutrition (TPN) is a highly concentrated intravenous nutritional solution that provides essential nutrients. It is administered through a central venous access device to ensure proper dilution and delivery.
Choice B rationale:
A midline catheter is not appropriate for administering TPN, as it may not be suitable for the concentrated solution.
Choice C rationale:
Subcutaneous administration is not suitable for TPN, as it requires intravenous access to provide the necessary nutrients directly into the bloodstream.
Choice D rationale:
Intraosseous access is not commonly used for long-term nutritional support like TPN; it is more often used for emergent situations.
