Before administering a scheduled dose of insulin to a 10-year-old child who is learning diabetic self-care, which information is most important for the practical nurse (PN) to ask the child?

A. Checking the child’s blood glucose level via fingerstick is the most important step before administering insulin to prevent hypoglycemia or ensure the appropriate dose. B. Exercise affects blood sugar, but the immediate priority is verifying the blood glucose level. C. Urination patterns can indicate hyperglycemia, but they are not the most critical factor before insulin administration. D. Eating is important, but insulin dosing should be based on blood glucose readings and meal intake combined.
