问题 单项选择题 A1/A2型题

奏效速度可与静脉注射相媲美的是()

A.栓剂

B.软膏剂

C.气雾剂

D.膜剂

E.滴丸

答案

参考答案:C

解析:吸入气雾剂的吸收速度很快,不亚于静脉注射,主要是因为肺部吸收面积巨大,肺泡囊的总表面积可达70~100m2,且肺部毛细血管丰富、血流量大,细胞壁和毛细血管壁的厚度只有0.5~1μm,转运距离极短,故药物到达肺泡囊即可立即起效。而栓剂、软膏剂、膜剂、滴丸剂的吸收过程相对较慢,有明显的吸收相。故本题答案选择C。

     Mr and Mrs Brown had always spent their summer holidays in New Jersey(新泽西)in the past, staying in a small inn(旅店)at the foot of a hill.

     One year, however, Mr Brown made a lot of money in his business, so they decided to go to London

and stay at a really good hotel while they went touring around that famous city.

     They flew to London and arrived at their hotel late one evening. They had expected that they would

have to go to bed hungry, because in that small inn in New Jersey, no meals were served after seven. They were surprised when the waiter asked whether they would take dinner there that night. “Are you still

serving dinner?” asked Mr Brown. “Yes, certainly sir,” answered the waiter. “We serve it until half past

nine.”

   "What are the times of meals then?” asked Mr Brown. “Well, sir,” answered the waiter, “we serve breakfast from seven to half past eleven in the morning, lunch from twelve to three in the afternoon, tea from four to five, and dinner from six to half past nine.”

    "But that hardly leaves any time for us to see the sights of London.” said Mr Brown.
