A nurse is providing teaching for a client who has a new diagnosis of type 1 diabetes mellitus about sick-day roles which information should the nurse include?

Rationale: A. "Call your provider if you have a fever for more than 24 hours.": Clients with type 1 diabetes are at risk for complications from illness, but the typical guideline is to contact the provider if a fever persists more than 48 hours or if blood glucose remains elevated despite home management. Fever alone for 24 hours may not require immediate provider contact if other sick-day protocols are followed. B. "Skip a meal if you are nauseous and vomiting.": Skipping meals can worsen hyperglycemia and increase the risk of diabetic ketoacidosis (DKA) in type 1 diabetes. Clients should be encouraged to consume small, frequent meals or clear liquids and maintain carbohydrate intake to prevent catabolism and ketone formation. C. "Test your urine for ketones if your blood glucose is greater than 280 mg/dL (15.5 mmol/L).": Monitoring for ketones during illness or when blood glucose exceeds 250–300 mg/dL is essential to detect early diabetic ketoacidosis. Urine ketone testing helps identify ketone buildup from fat breakdown, allowing timely intervention and preventing serious complications. D. "Check your blood glucose 4 times a day.": During sick days, blood glucose should be monitored every 3–4 hours or more frequently because illness can cause rapid fluctuations. Checking only four times a day may be insufficient to detect hyperglycemia and ketone formation promptly.
