Answer:
To calculate the maximum number of grams of carbohydrates available for the rest of the day, we need to consider the patient's total daily carbohydrate allowance based on their 2000-kcal diet and subtract the amount already consumed for lunch.
Let's assume that the recommended percentage of daily carbohydrates in a 2000-kcal diet is 50% (although actual percentages may vary based on individual dietary needs).
Step 1: Calculate the total daily carbohydrate allowance:
Total Daily Carbohydrate Allowance = 50% of 2000 kcal
Total Daily Carbohydrate Allowance = 0.50 * 2000 kcal
Total Daily Carbohydrate Allowance = 1000 kcal
Step 2: Subtract the amount of carbohydrates consumed for lunch:
Carbohydrates available for the rest of the day = Total Daily Carbohydrate Allowance - Carbohydrates consumed for lunch
Carbohydrates available for the rest of the day = 1000 kcal - 60 kcal
Now, we need to convert the remaining calories back to grams of carbohydrates. Since 1 gram of carbohydrates provides approximately 4 calories:
Carbohydrates available for the rest of the day (in grams) = (940 kcal) / (4 kcal/gram)
Carbohydrates available for the rest of the day ≈ 235 grams (rounded to the nearest whole number)
Therefore, the maximum number of grams of carbohydrates available for the rest of the day is approximately 235 grams.
