Type 2 diabetes management focuses on preventing complications and controlling blood glucose levels through a combination of lifestyle modifications, medication, and monitoring. Primary interventions target the root causes of disease progression, with lifestyle changes being the cornerstone of management, as supported by evidence-based guidelines.

Option A (Lifestyle change education): Lifestyle change education, including diet, exercise, and weight management, is the primary intervention for type 2 diabetes. NAHQ CPHQ study materials and clinical guidelines (e.g., American Diabetes Association) emphasize that lifestyle modifications are foundational because they address insulin resistance and improve glycemic control, reducing the need for medications and preventing complications.

Option B (Free medication delivery): While access to medications is important, it is a secondary intervention that supports adherence rather than addressing the underlying causes of type 2 diabetes. Delivery alone does not promote behavior change.

Option C (No-cost annual screening tests): Screening tests (e.g., HbA1c or retinopathy screening) are important for monitoring and early detection of complications but are not primary interventions for managing the disease itself. They are preventive or diagnostic rather than therapeutic.

Option D (Lowered cost of medications): Reducing medication costs improves access but, like free delivery, is a supportive measure rather than a primary intervention. It does not directly address lifestyle factors critical to disease management.
