Q

A client weighs 130 lbs. She is close to her desirable weight and consumes a total of 40g of protein/ day. The most appropriate nutritional counseling would be to

A

increase her protein intake…

(Recommended dietary allowance for protein for both men and women is set at 0.8g of high-quality protein per kilogram of desirable body weight per day.

130lbs divided by 2.2 lbs/kg = 59kg body weight

59kg x 0.8g protein/kg = 47g protein/ day.

clients protein intake is lower than her estimated needs.

Q

The total number of kilocalories in a snack that contains 10g carbohydrate, 2g protein, and 5g fat is _____ kcal

A

93

10g carbohydrate x 4kcal/g = 40kcal
2g protein x 4kcal/g = 8kcal
5g fat x 9kcal/g = 45kcal
Total calories = 40kcal + 8kcal + 45kcal = 93kcal
