Final answer:
The correct option is (a). The nurse should focus on a family history of coronary artery disease, high incidence of cardiovascular disease in older people, and the elevation of the patient's serum low-density lipoprotein (LDL) level.
Step-by-step explanation:
The nurse should focus on the following risk factors for coronary artery disease (CAD) when developing a health teaching plan for a 60-year-old man:
- Family history of coronary artery disease: A family history of cardiovascular disease increases a person's chance of developing heart disease.
- High incidence of cardiovascular disease in older people: The risk of developing CVDs increases with age and is greater in males than females at most ages.
- Elevation of the patient's serum low-density lipoprotein (LDL) level: High levels of LDL in the blood are definitely risk factors for cardiovascular disease.
In addition to these factors, it is important to address other modifiable risk factors such as smoking, lack of exercise, and high-fat diet. By making healthy lifestyle choices, the risk of developing CVD can be reduced.
