A nurse is developing a plan of care for a client who has type 1 diabetes mellitus. Which of the following interventions should the nurse include in the plan?

Choice A reason: Consuming 30 g of fiber daily benefits digestion and glycemic control but is not specific to type 1 diabetes management. Blood glucose monitoring is critical, making this a secondary intervention. Choice B reason: Oral hypoglycemics are used for type 2 diabetes, not type 1, which requires insulin due to absolute insulin deficiency. This is incorrect for type 1 diabetes management. Choice C reason: Monitoring blood glucose four times daily is essential for type 1 diabetes to guide insulin dosing and prevent hypo- or hyperglycemia. This ensures tight glycemic control, making it the correct intervention. Choice D reason: A bulk-forming laxative addresses constipation, not a primary concern in type 1 diabetes. Glucose monitoring directly manages the condition, making laxatives irrelevant to the care plan.
