A nurse is providing teaching to the parent of a school-age child who has diabetes mellitus about managing diabetes during illness. Which of the following statements by the parent indicates an understanding of the teaching?

A. Withholding insulin when the child has a poor appetite can lead to hyperglycemia and diabetic ketoacidosis since insulin is still needed during illness even if intake is reduced. Illness typically increases stress hormones, which raise blood glucose levels, making insulin even more necessary. B. Offering 20 grams of carbohydrates every 2 hours might not be sufficient or appropriate for all children; carbohydrate intake should be balanced with insulin and blood glucose monitoring. Proper carbohydrate intake helps maintain energy and prevent hypoglycemia, especially if the child is eating less than usual. C. Increasing fluid intake is important during illness to prevent dehydration and help manage blood glucose levels, as illness can cause increased glucose levels and fluid loss. Adequate hydration also supports kidney function and helps flush excess glucose from the bloodstream. D. Monitoring blood glucose every 8 hours is too infrequent during illness; blood glucose should be checked every 3 to 4 hours to detect and manage hyperglycemia or hypoglycemia promptly. Frequent monitoring allows timely insulin dose adjustments and early intervention.
