A nurse is reinforcing teaching of a female client who has a family history of type 2 diabetes mellitus. The nurse should include which of the following risk factors for developing type 2 diabetes mellitus in the teaching?

A. Triglyceride level of 100 mg/dL: A triglyceride of 100 mg/dL is within a healthy range and is not a risk marker for type 2 diabetes. B. Sedentary lifestyle: Lack of regular physical activity increases insulin resistance and is a well-established risk factor for developing type 2 diabetes. C. Blood glucose of 98 mg/dL: A fasting glucose of 98 mg/dL is normal (just under the prediabetes threshold) and by itself is not a risk factor. D. Recent viral infection: Viral infections are more commonly associated with triggering autoimmune (type 1) diabetes than with causing type 2 diabetes.
