Step-by-step explanation:
The modifiable risk factors for the older adult male client who suffered a heart attack are Alcohol intake (A), Smoking (B), and Stress (C). Modifiable risk factors refer to lifestyle choices that an individual has the ability to change or control, such as diet, alcohol and tobacco use, and the level of physical activity.
