Answer :
Final answer:
The protein component represents approximately 25% of the total daily calories.
Explanation:
To calculate the percentage of the total daily calories represented by the protein component, we need to determine the number of protein calories and the total calories in the parenteral nutrition order.
- First, we calculate the protein calories by multiplying the grams of protein (105g) by the conversion factor of 4 calories per gram of protein. This gives us 420 calories.
- Next, we add up the calories from all the components in the order:
- Dextrose: 370 grams x 3.4 calories per gram = 1258 calories
- Amino acids: 105 grams x 4 calories per gram = 420 calories
- Total calories = 1258 + 420 = 1678 calories
- Finally, we calculate the percentage of protein calories by dividing the protein calories by the total calories and multiplying by 100: (420/1678) x 100 ≈ 25%
