A nurse is caring for a 7-year-old child who has an upper respiratory infection and type 1 diabetes mellitus. Which of the following statements by the mother indicates a need for further instruction?

A. Reporting changes in breathing or mental status is appropriate, as these can be signs of worsening illness or diabetic ketoacidosis. B. Contacting the provider for a persistent fever despite treatment is appropriate and shows good understanding of when to seek medical help. C. Promoting hydration with sugar-free fluids every 30 minutes is appropriate during illness to help prevent dehydration and manage blood glucose levels. D. Checking blood glucose only twice a day is insufficient during illness. Children with type 1 diabetes should have their blood glucose monitored more frequently—usually every 3 to 4 hours—when sick, due to the risk of hyperglycemia or hypoglycemia.
