An adolescent with type 1 diabetes has been sick at home and call the clinic nurse. The parents report that the child's urine is positive for ketones. The nurse would instruct the parents to take which action?

Rationale: A. Encouraging the child to drink plenty of fluids helps prevent dehydration and flushes out ketones, which is an important initial home management step. B. Administering a double dose of insulin is unsafe and can cause hypoglycemia. C. Holding insulin doses is contraindicated as insulin is needed to reduce ketones and manage blood glucose. D. Immediate clinic visit may be necessary if symptoms worsen, but initial advice focuses on hydration and continuing insulin.
