Folate and other B
elements,
vitamins

Which statement defines resting energy expenditure (REE)? ( Correct
answers
the amount ) It of
is energy (in kcal) needed by the body for the maintenance
of lifea at
over 24-hour
rest
period.
Calculate the total energy expenditure (TEE) using Mifflin-St. Jeor formula
for a patient who is mildly obese. ( Correct answers ) 1685 kcal/day;
Patient height in inches: (5 feet x 12 in/ft) + 4 in = 64 in. Patient's height
in cm: 64 in x 2.54 cm/in = 162.56. Patient's weight in kg: 178 lbs / 2.2
lbs/kg = 80.91. Multiply the patient's height, weight, and age to the
respective numbers in the formula before adding height and weight
together and subtracting the age total and 161. Then complete the
formula by multiplying the total by the PA. TEE = [(10 x 80.91) + (6.25 x
162.56) - (5 x 52) - 161] x 1.2 = 1685 kcal/day.
