A nurse is teaching about the risk factors of developing a stroke with a group of older adult clients. Which nonmodifiable risk factors should the nurse include in the teaching?

Rationale: A. Obesity is a modifiable risk factor, as it can be addressed through lifestyle changes such as diet and exercise. B. Race is a nonmodifiable risk factor; certain races may have a higher risk of stroke due to genetic and environmental factors. C. History of smoking is a modifiable risk factor because individuals can choose to quit smoking to reduce their risk of stroke. D. History of hypertension is also a modifiable risk factor; while having high blood pressure increases the risk of stroke, it can be managed with lifestyle changes and medications.
