A nurse teaches a patient with newly diagnosed Type 1 Diabetes about sick-day management. Which statement indicates a need for further teaching?

Rationale: A. "Test my blood sugar regularly" is correct understanding. During illness, blood glucose can fluctuate widely due to stress hormones, infection, or decreased appetite. Frequent monitoring (every 3–4 hours) is essential for preventing hyperglycemia, hypoglycemia, or diabetic ketoacidosis (DKA). This statement shows proper understanding. B. Blood glucose monitoring should continue consistently during illness, regardless of how the patient feels. Skipping checks can lead to undiagnosed hyperglycemia or DKA, which is dangerous in Type 1 Diabetes. Illness can mask symptoms, so relying on feeling better is unsafe and indicates a need for further teaching. C. Insulin should never be skipped, even if the patient is unable to eat, because omitting insulin in Type 1 Diabetes can lead to rapid development of hyperglycemia and DKA. This demonstrates correct knowledge of sick-day management. D. High blood glucose increases the risk of ketone production. Checking urine or blood ketones helps detect early DKA, allowing timely intervention. This shows appropriate understanding of sick-day monitoring and complication prevention.
