A 45-year-old auto mechanic comes to the physician’s office because an exacerbation of his psoriasis is making it difficult to work. He tells the nurse that his finger joints are stiff and sore in the morning. The nurse should respond by（）
A. inquiring further about this problem because psoriatic arthritis can accompany psoriasis vulgaris.
B. suggesting he take aspirin for relief because it’s probably early rheumatoid arthritis.
C. validating his complaint but assuming it’s an adverse effect of his vocation.
D. asking him if he has been diagnosed or treated for carpal tunnel syndrome.
参考答案：A
解析：
Anyone with psoriasis vulgaris who reports joint pain should be evaIuated for psoriatic arthritis. Approximately 15% to 20% of individuals with psoriasis will also develop psoriatic arthritis, which can be painful and cause deformity. It would be incorrect to assume that his pain is caused by early rheumatoid arthritis or his vocation without asking more questions or performing diagnostic studies. Carpal tunnel syndrome causes sensory and motor changes in the fingers rather than localized pain in the joints.
