A client, age 59, complains of leg pain brought on by walking several blocks--a symptom that first arose several weeks ago. The client’s history includes diabetes mellitus and a two-pack-a-day cigarette habit for the past 42 years. The physician diagnoses intermittent claudication and prescribes pentoxifylline (Trental), 400 mg three times daily with meals. The nurse should provide which instruction concerning long-term care（）
A. "Practice meticulous foot care. "
B. "Consider cutting down on your smoking. "
C. "Reduce your level of exercise. "
D. "See the physician if complications occur. "
参考答案：A
解析：
Intermittent claudication and other chronic peripheral vascular diseases reduce oxygenation to the feet, making them susceptible to injury and poor healing. Therefore, meticulous foot care is essential. The nurse should teach the client to bathe the feet in warm water and dry them thoroughly, cut the toenails straight across, wear well-litting shoes, and avoid taking medications unless the physician approves. Because nicotine is a vasoconstrictor, this client should stop smoking, not just consider cutting down. Daily walking is beneficial to clients with intermittent claudication. The client must see the physician regularly to evaluate the effectiveness of the therapeutic regimen, not just when complications occur.
