An ICU nurse is caring for a client receiving total parenteral nutrition (TPN) via IV. The client’s infusion ended 2 hours ago and the pharmacy has not yet sent another bag. The client is diaphoretic and tachycardic, and states he feels weak, dizzy, and fatigued. The nurse suspects

  1. dehydration.
  2. fluid volume overload.
  3. hyperglycemia.
  4. hypoglycemia.
Number 4 is correct.
Rationale: Total parenteral nutrition (TPN) is high in dextrose, and if it is suddenly stopped, the client can become hypoglycemic. The patient could also be dehydrated, but the priority would be blood glucose control.
