Answer to Question 1

An insulin: CHO ratio is an individualized ratio that specifies how many grams of carbohydrate one unit of insulin will cover. It can be determined by dividing 500 by the total daily insulin dose (TDD) of that person.
2 Pop-Tarts = 76 grams CHO
8 oz. skim milk = 12 g CHO
Total: 88 grams CHO/15 = 5.8 or 6 units to cover this meal

Answer to Question 2

Carbohydrate needs based on 45-65 of total kcal from CHO:
2400 x 0.45 = 1080 kcal/4 kcal/g = 270 grams CHO/d/15 grams/serving = 18 servings/day
2400 x 0.65 = 1560 kcal/4 kcal/g = 390 grams CHO/d/15 grams/serving = 26 servings/day
Current meals/snacks consumed: Breakfast, lunch, dinner, and a snack before soccer practice
Nutrition prescription:
90 grams CHO for breakfast, lunch, and dinner (6 CHO equivalents/meal)
30 grams CHO (2 CHO equivalents) for snacks, twice per day (one mid-morning and one before soccer practice or other physical activity)
It is typical in pediatric practice to not prescribe a certain amount of CHO. It is more important for the patient to understand the insulin: CHO ratio and cover her intake accordingly.
