Final answer:
To meet the protein requirement of 1.4g/kg/day for a 21-pound pediatric patient, 84 mL of Nutren 2.0, which provides 16g/dL of protein, is required per day.
Step-by-step explanation:
To calculate how many milliliters of Nutren 2.0 are required per day to meet the 21-pound pediatric patient's protein requirement of 1.4g/kg/day, we will perform the following calculations:
- Convert the patient's weight from pounds to kilograms by dividing by 2.2 pounds per kilogram: 21 lb ÷ 2.2 lb/kg = 9.545 kg (rounded to three decimal places).
- Multiply the patient's weight in kilograms by the required protein per day: 9.545 kg × 1.4 g/kg/day = 13.363 g of protein per day.
- Since Nutren 2.0 provides 16 grams of protein per deciliter (dL), we need to calculate how many deciliters are needed for 13.363 grams of protein: 13.363 g ÷ 16 g/dL = 0.8352 dL.
- Convert deciliters to milliliters by multiplying by 100 (since 1 dL = 100 mL): 0.8352 dL × 100 mL/dL = 83.52 mL.
- Round to the nearest whole number: 84 mL of Nutren 2.0 are required to meet the protein requirement.
Therefore, 84 mL of Nutren 2.0 is needed daily to meet the pediatric patient's protein requirement.
