,Current patterns of consumption
- correct answer Current trends and habits regarding food intake.
The 2020-2025 Dietary Guidelines for Americans
- correct answer A set of recommendations for healthy eating patterns and nutrition.
Dietary references intakes (DRIs)
- correct answer A system of nutrition recommendations that includes various dietary reference values.
Which dietary element does the nurse know is included on the MyPlate visual?
- correct answer Fruit, Grains, Vegetables, Protein
How many kilocalories are consumed when eating 16g of fat?
- correct answer 144; 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 answer Water
Which dietary reference intake (DRI) panel was developed by the Food and Nutrition Board of the
Institute of Medicine?
- correct answer Antioxidants, Trace elements, Folate and other B vitamins
Which are the preferred reference values for evaluating diets in healthy people?
- correct answer Dietary reference intakes
In which category of the daily recommended intake of (DRI) interconnected categories will the patient
fall if a diet that is 35% fat is consumed?
- correct answer Tolerable upper intake level
Which special nutrient should an older woman include in her meal plan?
- correct answer Foods fortified with vitamin B12
,Which nutrient DRIs were increased to promote bone health?
- correct answer Calcium and Vitamin D
What is the recommended daily sodium intake for an older patient with heart failure?
- correct answer 1500 mg/day
Which statement defines resting energy expenditure (REE)?
- correct answer It 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 answer 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.
In a well-nourished person, which anatomical structure holds a 12 to 48-hour reserve of glycogen, a
source of stored energy?
- correct answer Muscle, Liver
The clinician is measuring the basal energy expenditure (BEE) of a patient using food consumption and
physical activity records. Which factor can increase the BEE?
- correct answer Increased physical activity or muscle mass.
Increased lean body mass
- correct answer A condition where there is an increase in the amount of lean tissue in the body.
Nutrient-dense food
- correct answer Foods that are high in nutrients relative to their calorie content.
Normal bodily functions
- correct answer Essential physiological processes necessary for sustaining life.
, Tissue growth and repair
- correct answer The process of cellular regeneration and recovery in the body.
Body temperature regulation
- correct answer The ability of the body to maintain its internal temperature within a certain range.
Predictive formula reliability
- correct answer Factors that can affect the accuracy of predictions made by formulas, such as disease
state and age.
Congenital hypothyroidism
- correct answer A metabolic condition present at birth that affects thyroid function.
Hormone levels
- correct answer The concentration of hormones in the body that can influence various physiological
functions.
Body Mass Index (BMI)
- correct answer A measurement that uses height and weight to assess body fat and categorize
individuals.
Carbohydrates
- correct answer A macronutrient that is a primary source of energy for the body.
Energy balance
- correct answer The state achieved when the calories consumed equal the calories expended over time.
Basal energy expenditure
- correct answer The number of calories required to keep your body functioning at rest.
Ventilated hood
- correct answer A method used to measure the basal energy expenditure of athletes with high
accuracy.
