Answer to Question 1

ANS: B
An energy expenditure (EE) of 30-40 kcal/hr/m2 is normal for an adult. The EE of 20 kcal/hr/m2 is less than 80 of predicted and is considered a hypometabolic state. Starvation creates a hy-pometabolic state. Pregnancy, hyperthyroidism, and stimulant drugs create hypermetabolic states.

Answer to Question 2

ANS: B
A healthy adult consuming a typical American diet will have a respiratory quotient (RQ) range from 0.80-0.85. An RQ of 0.7 is indicative of lipid metabolism as seen in prolonged starvation or severe sepsis. The RQ for the metabolism of pure carbohydrates is 1.0. An RQ of 0.9 would mean that the individual is consuming a higher amount of carbohydrates than a normal diet.
