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?

The correct answer is D. When a child with type 1 diabetes mellitus is sick, it is important to monitor blood sugar more frequently than usual to prevent complications like hyperglycemia or hypoglycemia. Checking blood sugar only twice a day during illness may lead to missed fluctuations. A sick child's blood sugar levels can be more unpredictable, so more frequent monitoring is necessary. Reporting a change in breathing (A), notifying the doctor if temperature is not controlled (B), and encouraging hydration (C) are all appropriate actions to take care of a child with an upper respiratory infection and diabetes.
