On a routine visit to the physician, a client with chronic arterial occlusive disease reports stopping smoking after 34 years. To relieve symptoms of intermittent claudication, a condition associated with chronic arterial occlusive disease, the nurse should recommend which additional measure（）
A. Taking daily walks.
B. Engaging in anaerobic exercise.
C. Reducing daily fat intake to less than 45% of total calories.
D. Avoiding foods that increase levels of high-density lipoproteins (HDLs).
参考答案：A
解析：
Daily walks relieve symptoms of intermittent claudication, although the exact mechanism is unclear. Anaerobic exercise may exacerbate these symptoms. Clients with chronic arterial occlusive disease must reduce daily fat intake to 30% or less of total calories. The client should limit dietary cholesterol because hyperlipidemia is associated with atherosclerosis, a known cause of arterial occlusive disease. However, HDLs have the lowest cholesterol concentration, so this client should eat foods that raise HDL levels.
