answerFruit, Grains, Vegetables, Protein
How many kilocalories are consumed when eating 16g of fat? - correct answer144;
there are 9 kcal in each gram of fat. To determine the amount of kcal in 16g of fat, 9
kcal is multiplied by 16g. There are 144 kcal in 16g of fat.
Which provides an essential base for all metabolic processes? - correct answerWater

Board of the Institute of Medicine? - correct answerAntioxidants, Trace elements, Folate
and other B vitamins
Which are the preferred reference values for evaluating diets in healthy people? -
correct answerDietary reference intakes

and Vitamin D
What is the recommended daily sodium intake for an older patient with heart failure? -
correct answer1500 mg/day
Which statement defines resting energy expenditure (REE)? - correct answerIt is the
amount of energy (in kcal) needed by the body for the maintenance of life at rest over a
24-hour period.
Calculate the total energy expenditure (TEE) using Mifflin-St. Jeor formula for a patient
who is mildly obese. - correct answer1685 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.

amount of lean tissue in the body.

for sustaining life.
Tissue growth and repair - correct answerThe process of cellular regeneration and
recovery in the body.
Body temperature regulation - correct answerThe ability of the body to maintain its
internal temperature within a certain range.
Predictive formula reliability - correct answerFactors that can affect the accuracy of
predictions made by formulas, such as disease state and age.
Congenital hypothyroidism - correct answerA metabolic condition present at birth that
affects thyroid function.
Hormone levels - correct answerThe concentration of hormones in the body that can
influence various physiological functions.
Body Mass Index (BMI) - correct answerA measurement that uses height and weight to
assess body fat and categorize individuals.
Carbohydrates - correct answerA macronutrient that is a primary source of energy for
the body.
Energy balance - correct answerThe state achieved when the calories consumed equal
the calories expended over time.
Basal energy expenditure - correct answerThe number of calories required to keep your
body functioning at rest.
Ventilated hood - correct answerA method used to measure the basal energy
expenditure of athletes with high accuracy.
Respiratory effort - correct answerThe energy expended during breathing, which is
significant in metabolic conditions.
