  a. glucose tolerance is often impaired.
  b. they may cause hypersecretion of insulin.
  c. they result in excess carbon dioxide pro-duction.
  d. they may lead to development of diabetes mellitus.

Question 2

Answer to Question 1

C
Parenteral nutrition support for patients with acute respiratory failure should not use high glucose concentrations because they result in excess carbon dioxide production. Lipids should be used to provide a significant proportion of nonprotein kcals (1 to 2 g lipid per kg body weight). Glucose tolerance is not affected by respiratory failure. Infusion of high concentrations of glucose does not cause hypersecretion of insulin or lead to development of diabetes mellitus.

Answer to Question 2

A
Most patients with acute respiratory failure require enteral or parenteral nutrition support because they require mechanical ventilation and cannot eat normally with a breathing tube in place.
