Final answer:
The nurse should infuse a dextrose solution until the TPN is available to maintain patient glucose levels and prevent hypoglycemia.
Step-by-step explanation:
If a nurse is informed of a delay in the delivery of the next bag of total parenteral nutrition (TPN) for a patient with a peripherally inserted central catheter, the appropriate action to take would be to infuse a dextrose solution until the TPN is available. Administering a bolus of TPN or discontinuing the infusion until the solution arrives might cause harm and disrupt the patient's nutritional status and glucose levels. Consulting with a healthcare provider is a proactive step, but it does not address the immediate need to maintain an appropriate glucose level for the patient. Therefore, the correct action is c) Infuse a dextrose solution until the TPN is available.
