Case Study 1

Steven is a 44-year-old male who is 5 ft 11 in tall and weighs 182 pounds. Over the lastmonth, he has lost approximately 10 pounds, which he blames on loss of appetite andfatigue. When he went to his family doctor with flu-like symptoms, a blood test revealed avery high white blood cell count, low platelet count, and low hemoglobin. The doctor toldhim to proceed to the hospital for admission to rule out acute leukemia. Further laboratorytests are pending. Admitting orders include a regular diet. Steven does not have a significantmedical history. He is married, has three children, and enjoys a successful career.

Calculate and evaluate Steven's weight according to the following standards:

BMI

Percent weight change

Based on Steven's weight and weight change, is he at nutritional risk?

Does Steven's possible diagnosis place him at nutritional risk?

What other criteria would help determine his level of risk?

Calculate his estimated calorie requirements. Calculate his Recommended DietaryAllowance (RDA) for protein.

If he is treated for leukemia, his protein need may increase to approximately 1.2 g protein/kg.How much would he then require?

The hospital's diet manual says that, on average, a regular diet provides 2400 caloriesand 90 g of protein. Is this diet adequate to meet his needs?
