Answer to Question 1

ANS: C
Under normal conditions, proteins contribute only minor amounts to energy metabolism. Note that the percentage of protein used represents the normal turnover rate for replenishing structural and functional proteins in the body. Proteins might contribute significantly to energy expendi-ture, however, in cases of starvation.

Answer to Question 2

ANS: C
An increase in body temperature of 1 F will cause a 10 increase in metabolic rate. If the pa-tient has a fever of 103 F, subtracting 98.6 F from the 103 F yields 4.4 F. A 1 F increase causes a 10 rise in metabolic rate, so 4.4 10 will equal a 44 increase.
