A client is undergoing a diagnostic test for peripheral vascular disease (PVD). Which of the following tests is most commonly used to assess blood flow in the lower extremities?

A) Correct - Encouraging the client to decrease tobacco and alcohol consumption can significantly reduce their risk of peripheral vascular disorders. Smoking and excessive alcohol intake are known risk factors for various vascular conditions.

B) Incorrect - Increasing caffeine intake does not have a significant impact on the risk of peripheral vascular disorders. It is not a primary factor contributing to the development of such conditions.

C) Incorrect - Daily fiber intake, if adequate, can be beneficial for cardiovascular health. A high-fiber diet can help reduce cholesterol levels and improve overall vascular health.

D) Incorrect - Reducing physical activity is not recommended as a way to reduce the risk of peripheral vascular disorders. Regular physical exercise is essential for maintaining cardiovascular health and reducing the risk of many vascular conditions.

A) Incorrect - A high-stress lifestyle can contribute to various health issues, but it is not a genetic risk factor for aneurysms. Stress may exacerbate hypertension, which is a known risk factor.

B) Incorrect - Smoking history is a behavioral risk factor rather than a genetic one. Smoking damages blood vessels and increases the risk of aneurysms through direct and indirect mechanisms.

C) Correct - A positive family history of aneurysms is a genetic risk factor. Having a first-degree relative with a history of an aneurysm increases an individual's risk of developing one.

D) Incorrect - A sedentary lifestyle is a behavioral risk factor for aneurysms, not a genetic one. Lack of physical activity can contribute to hypertension and other risk factors.
