Certified Diabetes Care and Education Specialist (CDCES) Practice Exam

Which factor is crucial to consider when calculating the bolus dose for the patient?

1. The type of insulin used

2. The patient's carbohydrate intake

3. The length of the IV therapy

4. The patient's weight

The correct answer is: The patient's carbohydrate intake

When calculating the bolus dose for a patient, the patient's carbohydrate intake is crucial because insulin dosing is directly related to the amount of carbohydrates consumed. The primary goal of bolus insulin is to manage postprandial blood glucose levels, which are influenced by the quantity of carbohydrates present in a meal. A common approach involves using a carbohydrate-to-insulin ratio, which helps determine how much insulin is needed to counteract the increase in blood sugar that results from carbohydrate intake. Thus, if a patient's carbohydrate intake is accurately assessed, healthcare professionals can provide an appropriate bolus of insulin to help maintain optimal blood glucose control after meals. This individualized approach enhances glycemic management, reduces the risk of hyperglycemia, and promotes overall diabetes health. While the type of insulin used, the length of IV therapy, and the patient's weight can all play important roles in broader diabetes management strategies, they do not have the immediate, direct relationship to bolus dosing as carbohydrate intake does.
