Q: A 35-year-old sedentary male weighs 80 kg and is 1.8 m tall. Using the EER formula, what is his estimated energy requirement? (Use $PA = 1.00$ for sedentary men)

$EER = 662 - (9.53 \times 35) + 1.00 \times [(15.91 \times 80) + (539.6 \times 1.8)]$

Q: A 45-year-old woman is very active (PA = 1.45), weighs 65 kg, and is 1.65 m tall. What is her EER using the formula for women?

$EER = 354 - (6.91 \times 45) + 1.45 \times [(9.36 \times 65) + (726 \times 1.65)]$

Adequate Intake (AI)

Question 4

A 35-year-old sedentary male weighs 80 kg and is 1.8 m tall. Using the EER formula, what is his estimated energy requirement? (Use $PA = 1.00$ for sedentary men)

Accepted Answer

$EER = 662 - (9.53 	imes 35) + 1.00 	imes [(15.91 	imes 80) + (539.6 	imes 1.8)]$

Question 5

Which of the following statements about the Tolerable Upper Intake Level (UL) is correct?

Accepted Answer

UL is the highest level of daily intake that is likely to pose no risk of adverse health effects.

Question 6

A 10-year-old male consumes 1,800 mcg RAE of preformed Vitamin A daily. According to the UL table, what is the risk?

Accepted Answer

He is above the UL and at risk for toxicity.

Question 7

Which of the following best describes the Acceptable Macronutrient Distribution Range (AMDR) for adults?

Accepted Answer

Protein: 10-35%, Carbohydrates: 45-65%, Fat: 20-35%

Question 8

Which DRI value would be most useful for evaluating the safety of a high-dose vitamin supplement?

Accepted Answer

Tolerable Upper Intake Level (UL)

Question 9

A 3-year-old girl consumes 30 mcg of vitamin K daily. According to the AI table, what does this indicate?

Accepted Answer

She is likely meeting her vitamin K needs.

Question 10

Which of the following is TRUE regarding the relationship between RDA and EAR?

Accepted Answer

RDA is statistically derived from the EAR to cover the needs of nearly all healthy individuals.

Question 11

A 20-year-old woman is lactating. What is her RDA for Vitamin A?

Accepted Answer

$1,300\ 	ext{mcg RAE}$

Question 12

Which statement about Adequate Intake (AI) is correct?

Accepted Answer

AI is used as a nutrient intake goal when RDA cannot be determined.

Question 13

Which of the following nutrients does NOT have a Tolerable Upper Intake Level (UL) established?

Accepted Answer

Vitamin K

Question 14

A 45-year-old woman is very active (PA = 1.45), weighs 65 kg, and is 1.65 m tall. What is her EER using the formula for women?

Accepted Answer

$EER = 354 - (6.91 	imes 45) + 1.45 	imes [(9.36 	imes 65) + (726 	imes 1.65)]$

Question 15

Which of the following is NOT a factor considered in determining an individual's Estimated Energy Requirement (EER)?

Accepted Answer

Genetic predisposition to chronic disease

Question 16

A 16-year-old male consumes 3,500 mcg RAE of preformed Vitamin A daily. According to the UL table, what is the likely outcome?

Accepted Answer

He is above the UL and at risk for toxicity.

Question 17

Which of the following best describes the purpose of the Acceptable Macronutrient Distribution Range (AMDR)?

Accepted Answer

To recommend the percentage of calories from each macronutrient associated with reduced risk of chronic disease.

Question 18

True or False: There is both an RDA and AI established for each nutrient.

Accepted Answer

False

Question 19

Accepted Answer

Carbohydrate
