Question: 1 / 400

A student uses an insulin to carbohydrate ratio of 1 unit per 15 grams of carbohydrate. For a meal containing 45 grams of carbohydrate, how much insulin is needed?

1 unit

2 units

3 units

To determine the amount of insulin needed for the meal, you can apply the insulin-to-carbohydrate ratio provided. In this case, the student uses a ratio of 1 unit of insulin for every 15 grams of carbohydrate.

If the meal contains 45 grams of carbohydrate, you can calculate the required insulin by dividing the total grams of carbohydrate by the number of grams covered by each unit of insulin:

45 grams of carbohydrate ÷ 15 grams per unit = 3 units of insulin.

This calculation shows that for a meal with 45 grams of carbohydrates, the student needs to administer 3 units of insulin to effectively cover the carbohydrate intake. Understanding this ratio is essential for managing diabetes effectively, allowing individuals to match their insulin doses to their carbohydrate consumption accurately.
