How many kJ does this equal? a. 420 b. 480 c. 4200 d. 4800 ANS: A One kilocalorie is equal to 4.184 kJ (100 kcal 4.2 kJ/kcal = 420 kJ). REF: p. 19 2. Which of the following conditions is necessary to obtain an accurate measure of a patient’s basal metabolic rate (BMR)? a. Test at the end of the day when the patient is ready to go to sleep. b. Test 4 to 6 hours after the last meal. c. Test in the morning after the patient has awakened. d. Test in environmental conditions equal to body temperature. ANS: C For an accurate measurement of BMR, the test should be performed when the body is using its minimum amount of energy, usually in the morning after waking, and at least 10 to 12 hours after the last meal so as to not include the thermic effect of food. Clim ates above 86° F increase metabolism because of sweat gland activity. REF: p. 17 3. If a patient’s body temperature were 104.6° F, what would the BMR be compared with normal? a. 58% of normal b. 135% of normal c. 142% of normal d. 178% of normal ANS: C An increase in body temperature increases the BMR by 7% for every degree Fahrenheit above the normal 98.6° F (104.6 - 98.6 = 6° F; 6° F 7% ÷ 1° F = 42%). REF: p. 18 4. How does an elevation in body temperature with fever affect the metabolic rate?read more
