A nurse is providing education to a client with peripheral vascular disease about ways to improve blood circulation. Which activity should the nurse recommend?

A) This choice is correct. Elevating the legs above heart level while sitting can improve venous return, reducing swelling and promoting blood circulation in the legs. This position helps counteract the effects of gravity on blood flow.

B) This choice is incorrect because applying direct heat to the affected extremities is not a recommended method for improving blood circulation in peripheral vascular disease. Heat can cause vasodilation, which may exacerbate symptoms such as swelling and pain.

C) This choice is incorrect because crossing the legs while seated can impede venous return and contribute to blood pooling in the legs. It is not a recommended activity for individuals with peripheral vascular disease.

D) This choice is incorrect because limiting physical activity is not recommended for individuals with peripheral vascular disease. Regular physical activity, such as walking, can actually improve blood circulation and overall vascular health. However, individuals with peripheral vascular disease should be cautious not to overexert themselves and should consult with their healthcare provider regarding appropriate levels of physical activity.

Questions

A) This choice is correct. The ankle-brachial index (ABI) is a non-invasive test that compares the blood pressure in the arms and legs. The test involves using a blood pressure cuff and Doppler ultrasound to measure blood pressure in the ankles and arms. The ratio of ankle to brachial pressure helps assess the severity of peripheral vascular disease and determine if there is reduced blood flow to the legs.

B) This choice is incorrect because oxygen saturation in the extremities is not directly measured with an ankle-brachial index (ABI) test. Oxygen saturation is commonly measured using pulse oximetry, which assesses the percentage of hemoglobin in the blood that is saturated with oxygen.

C) This choice is incorrect because an ankle-brachial index (ABI) test is not used to measure blood glucose levels before and after meals. Blood glucose levels are typically assessed using a blood test or fingerstick glucose monitoring in clients with diabetes.

D) This choice is incorrect because an ankle-brachial index (ABI) test does not evaluate blood flow through the heart's chambers. It focuses on assessing blood pressure and blood flow in the arms and legs to diagnose peripheral vascular disease.
