Dennis Wilson is a 57-year-old chemical engineer who has had type 1 diabetes since he was 12 years old. He spent 34 years working in oil refineries, and he is a smoker. He is 5'11" tall and weighs 160 pounds. Over the past several years, he has experienced a gradual decline in kidney function. His GFR has declined to 27 mL/min per 1.73 m2.
-Mr. Wilson's estimated energy needs are _____.

Question

Dennis Wilson is a 57-year-old chemical engineer who has had type 1 diabetes since he was 12 years old. He spent 34 years working in oil refineries, and he is a smoker. He is 5'11" tall and weighs 160 pounds. Over the past several years, he has experienced a gradual decline in kidney function. His GFR has declined to 27 mL/min per 1.73 m2.
-Mr. Wilson's estimated energy needs are _____.​

Quizplus · Accepted Answer

Mr. Wilson's estimated energy needs can be calculated using the Mifflin-St. Jeor equation, which takes into account his age, sex, and body composition:

MR (men) = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5
MR = (10 × 72.5 kg) + (6.25 × 180 cm) - (5 × 57 years) + 5
MR = 1,825 + 1,125 - 285 + 5
MR = 2,670

His estimated energy needs will be lower than this due to his decreased kidney function, so we can apply a correction factor of 0.85:

Estimated energy needs = 2,670 × 0.85
Estimated energy needs = 2,269.5 or approximately 2,545 kcal per day.

Therefore, the best choice is C.
