支气管肺癌的症状是（）。
A.呼气性呼吸困难，双肺满布哮鸣音
B.端坐呼吸，双肺底水泡音
C.呼气性呼吸困难，两肺底湿啰音
D.发热，咳嗽，夜间阵发性气急，肺无异常体征
E.进行性呼吸困难，痰中带血
参考答案：E
解析：支气管哮喘的病因为支气管痉挛、狭窄，导致呼气时气流难以外出，出现呼气性呼吸困难；气流通过狭窄的气道，可出现哮鸣音。故选A。支气管肺癌癌性病灶进展较快，气道逐渐被阻，出现进行性呼吸困难，癌块侵蚀血脉，即可出现痰中带血，故选E。端坐呼吸，双肺底水泡音为左心衰竭的表现。呼气性呼吸困难，两肺底湿啰音为左心衰时肺淤血的表现。发热，咳嗽，夜间阵发性气急，肺无异常体征为急性气管-支气管炎的表现。
