A nurse is reviewing risk factors for a client who had a myocardial infarction. Which of the following should the nurse consider to be a nonmodifiable risk factor?

A. The client's activity level: Physical activity is a modifiable risk factor because the client can increase exercise to reduce cardiovascular risk. Lifestyle changes in activity level can significantly impact heart health and recovery after a myocardial infarction. B. The client's stress level: Stress is a modifiable risk factor as clients can employ stress-reduction techniques, counseling, or lifestyle modifications to lower cardiovascular risk. Managing stress can improve both short-term and long-term cardiac outcomes. C. The client's race: Race is a nonmodifiable risk factor because it is inherent and cannot be changed. Certain racial and ethnic groups have a higher prevalence of cardiovascular disease due to genetic, socioeconomic, and health access factors. D. The client's diet: Diet is a modifiable risk factor since clients can adjust their nutritional intake to reduce cholesterol, blood pressure, and overall cardiovascular risk. Nutritional counseling is often part of post-MI care to improve outcomes.
