    A 42-yrs-old man has a calculated resting energy expenditure of 1800 kcal/day (basal energy expenditure plus 10%). Match the following clinical situations with the appropriate daily energy requirement.
    a- 1600 kcal/day
    b- 2300 kcal/day
    c- 2800 kcal/day
    d- 3600 kcal/day
    e- 4500 kcal/day

    Answer: C. (Schwartz, 7/e, pp 33-40) Resting energy expenditure in the nonstressed patient is approximately 10% greater than basal energy expenditure. The resting energy expenditure increases directly proportional to the degree of stress. Studies by kidney and associates using indirect calorimetry have documented the relative degree of increase in resting energy expenditure for a variety of clinical situations. The following table summarizes these results:
    Clinical Starvation Change in Energy Expenditure
    Prolonged starvation Decreased 10-30%
    Skeletal trauma Decreased 10-30%
    Sepsis Decreased 30-60%
    Third-degree burns > 20% BSA Decreased 50-100%
