Question 1

Which of the following statements best describes the purpose of Dietary Reference Intakes (DRIs)?

Accepted Answer

DRIs provide specific recommendations for nutrient and caloric intake for healthy individuals.

Question 2

A 35-year-old pregnant woman is seeking advice on her nutrient intake. Which aspect of the DRIs is most relevant to her situation?

Accepted Answer

DRIs vary by population group, including pregnancy status.

Question 3

Which DRI value is defined as the intake level that meets the needs of 97–98% of healthy individuals in a particular group?

Accepted Answer

Recommended Dietary Allowance (RDA)

Question 4

If a nutrient does not have enough scientific evidence to establish an RDA, which DRI value is used instead?

Accepted Answer

Adequate Intake (AI)

Question 5

A patient consumes 400 mg of a nutrient daily. The EAR for this nutrient is 300 mg, and the RDA is 400 mg. What percentage of healthy individuals would this intake likely meet?

Accepted Answer

97–98%

Question 6

Which DRI value is used to assess the risk of adverse health effects from excessive nutrient intake?

Accepted Answer

Tolerable Upper Intake Level (UL)

Question 7

Calculate the Estimated Energy Requirement (EER) for a person using the following formula: $EER = 	ext{Basal Metabolic Rate} + 	ext{Activity Level}$. If a person's Basal Metabolic Rate is 1500 kcal and their Activity Level adds 500 kcal, what is their EER?

Accepted Answer

$EER = 1500 + 500 = 2000$ kcal

Question 8

Which DRI value is the only one that takes height and weight into account when establishing guidelines?

Accepted Answer

Estimated Energy Requirement (EER)

Question 9

The Acceptable Macronutrient Distribution Range (AMDR) recommends that carbohydrates should provide what percentage of total daily calories?

Accepted Answer

45–65%

Question 10

How does the AMDR differ from MyPlate recommendations?

Accepted Answer

AMDR is based on macronutrient intake, while MyPlate is based on food groups.

Question 11

Which statement accurately describes a difference between the Dietary Reference Intakes (DRIs) and the Dietary Guidelines for Americans (DGAs)?

Accepted Answer

DGAs focus on macronutrients and energy intake, while DRIs focus on micronutrients such as vitamins and minerals.

Question 12

A nutritionist is planning a diet for a patient and wants to avoid nutrient toxicity. Which DRI value should they consult?

Accepted Answer

Tolerable Upper Intake Level (UL)

Question 13

Which DRI value is most important for preventing nutrient inadequacy in a population?

Accepted Answer

Estimated Average Requirement (EAR)

Question 14

If a nutrient's intake is below the EAR, what is the likely implication for the population?

Accepted Answer

More than 50% of the population may be at risk of inadequacy.

Question 15

Which of the following is NOT a characteristic of the Dietary Guidelines for Americans (DGAs)?

Accepted Answer

Provides specific recommendations for every individual nutrient.

Question 16

A dietitian is comparing the DRIs and DGAs. Which statement is true for both?

Accepted Answer

Both provide recommendations for nutrient and caloric intake.

Question 17

Which DRI value is used to plan diets for groups rather than individuals?

Accepted Answer

Estimated Average Requirement (EAR)

Question 18

A person consumes 70g of protein per day, which is 20% of their total caloric intake. Does this fall within the AMDR for protein?

Accepted Answer

Yes, because the AMDR for protein is 10–35% of total calories.

Question 19

Which DRI value is most likely to be the highest for a particular nutrient?

Accepted Answer

Recommended Dietary Allowance (RDA)
