Q: A 35-year-old male weighs 187 pounds. Using the RDA, what is his daily protein requirement? (RDA = 0.8 g/kg, 1 kg = 2.2 lbs)

$$\frac{187}{2.2} \times 0.8 = 68.0$$ grams

Q: If Cindy consumes 100 grams of protein per day on her 1500 kcal diet, what percentage of her calories comes from protein? (1 g protein = 4 kcal)

$$\frac{100 \times 4}{1500} \times 100 = 26.7\%$$

Question 1

A 45-year-old male weighs 250 pounds. Using the RDA recommendation for protein intake (0.8 g protein per kg body weight per day), what is his daily protein requirement? (1 kg = 2.2 lbs)

Accepted Answer

$$\frac{250}{2.2} 	imes 0.8 = 90.9$$ grams

Question 2

Cindy is a 24-year-old woman weighing 250 lbs, consuming 1500 kcal/day to lose weight. The AMDR for protein is 10-35% of total calories. What is the range of protein (in grams) she should consume daily according to the AMDR? (1 g protein = 4 kcal)

Accepted Answer

$$\frac{1500 	imes 0.10}{4} = 37.5$$ grams to $$\frac{1500 	imes 0.35}{4} = 131.25$$ grams

Question 3

Lauren is a 27-year-old female, 5 ft. 7 in., weighing 155 lbs. Calculate her daily protein needs using the RDA recommendation. (1 kg = 2.2 lbs, RDA = 0.8 g/kg)

Accepted Answer

$$\frac{155}{2.2} 	imes 0.8 = 56.4$$ grams

Question 4

A 21-year-old female weighs 163 pounds. What is her protein requirement according to the RDA? (RDA = 0.8 g/kg, 1 kg = 2.2 lbs)

Accepted Answer

$$\frac{163}{2.2} 	imes 0.8 = 59.3$$ grams

Question 5

Cindy's RDA protein need is calculated as $$\frac{250}{2.2} 	imes 0.8 = 90.9$$ grams. Is this amount within the AMDR range for her 1500 kcal diet?

Accepted Answer

Yes, because 90.9 grams is between 37.5 and 131.25 grams

Question 6

Which of the following is a key consideration for Lauren, who is switching to a vegetarian diet but still consumes dairy and eggs, in meeting her protein needs?

Accepted Answer

Include a variety of plant-based proteins and animal products like eggs and dairy to ensure all essential amino acids are consumed

Question 7

A 35-year-old male weighs 187 pounds. Using the RDA, what is his daily protein requirement? (RDA = 0.8 g/kg, 1 kg = 2.2 lbs)

Accepted Answer

$$\frac{187}{2.2} 	imes 0.8 = 68.0$$ grams

Question 8

If Cindy consumes 100 grams of protein per day on her 1500 kcal diet, what percentage of her calories comes from protein? (1 g protein = 4 kcal)

Accepted Answer

$$\frac{100 	imes 4}{1500} 	imes 100 = 26.7\%$$

Question 9

Which of the following menu plans for Lauren (protein need: 56.4 grams/day) best meets her protein needs as a lacto-ovo vegetarian?

Accepted Answer

Breakfast: Greek yogurt (15g), Snack: Almonds (6g), Lunch: Egg salad sandwich (14g), Snack: Cheese stick (7g), Dinner: Lentil soup (16g)

Question 10

Which of the following statements about the RDA for protein is correct?

Accepted Answer

The RDA for protein is based on body weight in kilograms and is set at 0.8 grams per kilogram per day for healthy adults

Question 11

If a person consumes 60 grams of protein per day on a 2000 kcal diet, what percentage of their calories comes from protein? (1 g protein = 4 kcal)

Accepted Answer

$$\frac{60 	imes 4}{2000} 	imes 100 = 12\%$$

Question 12

Which of the following is a potential risk if Lauren, as a lacto-ovo vegetarian, does not consume a variety of protein sources?

Accepted Answer

She may not get all essential amino acids needed for optimal health

Question 13

A patient is consuming 80 grams of protein per day and weighs 160 lbs. Is this above, below, or within the RDA for protein? (RDA = 0.8 g/kg, 1 kg = 2.2 lbs)

Accepted Answer

Above the RDA (RDA = $$\frac{160}{2.2} 	imes 0.8 = 58.2$$ grams)

Question 14

Which of the following best describes the difference between the RDA and the AMDR for protein?

Accepted Answer

The RDA is a fixed amount based on body weight, while the AMDR is a percentage range of total caloric intake

Question 15

If Cindy increases her protein intake to 140 grams per day on her 1500 kcal diet, is she exceeding the AMDR for protein?

Accepted Answer

Yes, because $$\frac{140 	imes 4}{1500} 	imes 100 = 37.3\%$$, which is above the 35\% upper limit

Question 18

Which of the following scenarios best illustrates the application of both the RDA and AMDR for protein in a weight loss plan?

Accepted Answer

A person calculates their protein needs using both their body weight (RDA) and their calorie intake (AMDR) to ensure their intake is adequate and within recommended ranges
