  b. To prevent hyperglycemia and fluid overload
  c. To promote wound healing and maintain cell integrity
  d. To restore fluid and electrolyte imbalance

Question 2

Answer to Question 1

ANS: C
TPN is indicated for patients with severe burns who are in negative nitrogen balance. TPN enhances wound healing and provides the nutrients necessary to prevent cellular catabolism. While some pulmonary complications, such as aspiration pneumonia, do not occur with TPN, there is a risk of air embolism. Hyperglycemia and fluid overload may occur.

Answer to Question 2

ANS: B
The patient who is being treated with TPN and has dyspnea and rales is experiencing fluid overload. The nurse should slow the rate of the TPN and request an order for a diuretic. Patients perform the Valsalva maneuver during bag changes to help prevent pulmonary emboli. Patients receiving TPN are not necessarily at risk for aspiration pneumonia. Intravenous isotonic dextrose is given after sudden interruption of TPN to prevent hypoglycemia.
