The nurse is preparing to discontinue total parenteral nutrition (TPN) therapy for a patient who has been receiving TPN for several days. The nurse will contact the provider to discuss an order for
a. antibiotics.
b. intravenous insulin.
c. isotonic dextrose.
d. nasogastric feedings.
ANS: C
Abruptly discontinuing TPN can lead to hypoglycemia. Patients should receive an isotonic dextrose solution for 12 to 24 hours after TPN is discontinued to prevent this reaction. Antibiotics are used when signs of infection are observed. Intravenous insulin would compound hypoglycemia. Nasogastric feedings are indicated if the patient needs continued feeding therapy and has an intact GI tract.
