Answer to Question 1

ANS: D
Predicted values are based on gender and height, with reference values of approximately 18 mg/kg body weight/day for women to approximately 23 mg/kg body weight/day for men. Values of 60 to 80 of predicted indicate a mild deficit of muscle mass; 40 to 60 indicate a mod-erate deficit, and less than 40 of predicted suggest a severe depletion of muscle mass.

Answer to Question 2

ANS: C
Urinary nitrogen is the recommended value to use in determining nitrogen balance.
