D440 WGU HEALTH AND WELLNESS THROUGHNUTRITIONAL SCIENCE - CHAPTER 6 QUIZ
A 32-year-old female patient is 5 feet 5 inches (165 cm) tall and weighs 168 lb (76.4 kg).
She is moderately active and enjoys playing tennis four times a week. According to the
Mifflin-St. Jeor equation, the patient's total energy requirement is __ kcal per day.
Round the answer to the nearest whole number. - Answers-2784
The patient is 165 cm tall, weighs 76.4 kg, and is 32 years old. The PA coefficient for the
patient is 1.550 because she is moderately active.The Mifflin-St. Jeor TEE formula for
this patient is shown below.TEE (kcal/day) = (10 × weight [kg] + 6.25 × height [cm] - 5 ×
age [yr] - 161) × PATEE (kcal/day) = (10 × 76.4 + 6.25 × 165 - 5 × 32 - 161) × 1.550TEE
(kcal/day) = (764) + (1031.25) - (160 - 161) × 1.550TEE (kcal/day) = (764) + (1031.25) -
(-1) × 1.550TEE (kcal/day) = (1795.25) - (-1) × 1.550TEE (kcal/day) = (1796.25) ×
1.550TEE (kcal/day) = 2784.1875Rounded to the nearest whole number = 2784
kcal/day
A male patient is 6 feet 5 inches (195.5 cm) tall, weighs 190 lb (86.4 kg), and is 37 years
old. The patient is very active and enjoys running 2-3 miles a day and playing on a
recreational soccer team three times a week. Using the Harris-Benedict formula, the
patient's total energy requirement is __ kcal/day. Round the answer to the nearest
whole number. - Answers-3419
The patient's height is 195.5 cm, his weight is 86.4 kg, and he is 37 years old. The
patient engages in "heavy exercise," running daily and playing soccer three times per
week. Therefore his PA coefficient is 1.725.The Harris-Benedict TEE formula for this
patient is shown below.TEE (kcal/day) = 66.47 + (5 × height [cm]) + (13.75 × weight
[kg]) - (6.755 × age [yr]) × PATEE (kcal/day) = 66.47 + (5 × 195.5) + (13.75 × 86.4) -
(6.755 × 37) × 1.725TEE (kcal/day) = 66.47 + (977.5) + (1188) - (249.935) × 1.725TEE
(kcal/day) = (2231.97 - 249.935) × 1.725TEE (kcal/day) = (1982.035) × 1.725TEE
(kcal/day) = 3419.01Rounded to the nearest whole number = 3419 kcal/day
A 7-year-old girl who is 4 feet 1 inch (1.245 m) tall, weighs 63 lb (28.6 kg), and does not
engage in regular physical activity requires __ kcal per day according to the 2002 DRI
energy calculation. Round the answer to the nearest whole number. - Answers-1440
The DRI equation for a female who is 7 years old is as follows:EER = 135.3 - (30.8 ×
age [yr]) + PA × (10.0 × weight [kg] + 943 × height [m] + 20 kcal)The girl does not
engage in regular physical activity and therefore her PA coefficient would be 1.00
(sedentary).EER = 135.3 - (30.8 × 7) + 1.00 × (10.0 × 28.6 + 943 × 1.245 + 20 kcal)EER
= 135.3 - (215.6) + 1.00 × (286 + 1174.035 + 20 kcal)EER = 135.3 - (215.6) + 1.00 ×
(1480.035)EER = -80.3 + 1480.035EER = 1399.735Rounded to the nearest whole
number = 1400 kcal
