问题 单项选择题 A2型题

患者,男性,53岁,吸烟史33年,每日1包。有咳嗽咳痰病史约7年,气促进行性加重2年。近两个月发现痰中经常带有血丝,无脓痰,无发热,昨日起出现大口咯血,伴气促加重,感右胸隐痛。诊断应高度警惕下列哪种疾病()

A.支气管扩张并咯血

B.支气管肺癌

C.慢性支气管炎合并肺结核

D.慢性支气管炎合并肺栓塞

E.慢性支气管炎急性发作

答案

参考答案:B

解析:初看该题,像慢支炎或COPD的诊断,但因为没有发热、咳嗽咳痰增多和(或)黄脓痰,所以可排除E。肺栓塞一般急性起病,伴发热,很少咳血丝痰两个月,可排除D。一般而言,无低热、盗汗、乏力亦可排除C。患者无长期黄脓痰病史,本次发病亦无脓痰及发热,所以可排除A。该患者男性,45岁以上,吸烟指数>400,咯血为主就诊,伴右胸痛,气促加重,最有可能是肺癌,故应选答案B。
