How many non-protein calories are provided by 2 L of a 7% Aminosyn solution and 1 L of 10% dextrose in water?

How many non-protein calories are provided by 2 L of a 7% Aminosyn solution and 1 L of 10% dextrose in water?

• A. 300
• B. 340
• C. 400
• D. 500

Answer: (B)

To determine the non-protein calories from the given solutions, it’s necessary to calculate the caloric content provided by the dextrose solution since aminosyn solutions provide protein calories but no non-protein calories. For the dextrose solution, the calculation is based on the concentration of the dextrose and the volume used. A 10% dextrose solution has 10 grams of dextrose per 100 mL. Therefore, in 1 L (or 1000 mL) of a 10% solution, there are: \[ 10 \text{ g/100 mL} \times 1000 \text{ mL} = 100 \text{ g of dextrose} \] Each gram of dextrose provides 4 calories. Thus, the total non-protein calories from the dextrose solution would be: \[ 100 \text{ g} \times 4 \text{ calories/g} = 400 \text{ calories} \] In contrast, the 7% Aminosyn solution, while it does provide protein calories, does not contribute non-protein calories. Therefore, all the non-protein calories in this scenario come solely from the de
