Practice Question

A nurse prepares to replace the nearly empty container of total parenteral nutrition (TPN) for a client when she finds that there has been a delay in receiving the new container of solution from the pharmacy. Which of the following solutions should the nurse infuse until the next container of TPN solution becomes available?

Answer Choices:

Correct Answer:

Dextrose 10% in water

Rationale:

🧃When TPN is interrupted, infusing D10W maintains caloric intake and prevents hypoglycemia, preserving essential glucose supply.

⚖️The dextrose concentration in D10W better approximates TPN’s carbohydrate support than isotonic solutions, supporting metabolic stability.

🩸Avoiding abrupt withdrawal of hypertonic carbohydrate prevents rebound hypoglycemia, a critical patient safety concern.

🏥Using D10W as a bridge is a standard interim therapy that supports homeostasis until the full TPN becomes available.


📌Core Message

During an unexpected TPN delay, D10W is used to maintain glucose support and prevent rebound hypoglycemia, stabilizing the patient’s metabolic needs.
