Answer to Question 1

ANS: B
Excessive carbohydrate feeding can increase carbon dioxide production and may precipitate acute hypercapnic respiratory failure. Parenteral nutrition solutions containing amino acid formu-lations (arginine/lysine) can cause metabolic acidosis and thus increase ventilatory demand.

Answer to Question 2

ANS: D
