问题 单项选择题 A1/A2型题

发生青霉素过敏性休克时,临床最早出现的症状是()。

A.烦躁不安、血压下降

B.四肢麻木、头晕眼花

C.腹痛、腹泻

D.意识丧失、尿便失禁

E.喉头水肿、呼吸道症状

答案

参考答案:E

解析:喉头水肿、呼吸道症状是致敏细胞直接作用于呼吸道,呼吸道症状、喉头水肿是最早出现的。故本题选E。由于脑组织缺氧所致的中枢神经系统、循环衰竭,症状,如烦躁不安、血压下降、四肢麻木、头晕眼花、意识丧失、尿便失禁、腹痛、腹泻。避错:本题易错选B,过敏性休克首先的症状常表现为呼吸系统症状,若未缓解,随后出现循环系统症状,和继发出现中枢神经系统症状。常以呼吸道阻塞症状或皮肤瘙痒最早出现,必须注意倾听患者的主诉。故本题选E。

Dear Peter,

     Thanks for your last letter. I am happy to know you' had a very great funny vacation. As your best

pen pal, I'd like to tell you how I spent my vacation. I didn't go to school on May 1st and my parents

didn't go to work, so we went to visit Changbaishan. There are many buses to go there. We had a new

car and my mother drove the car there. Changbaishan is really an interesting place. Many people go

there every day. We saw lots of beautiful trees and had lunch under a tall tree. Then we went to Tian

Chi—a fantastic big lake (湖泊)—The water is blue and very clean. But nobody can swim in the water.

It can make it dirty and it is dangerous to swim in it. We took many photos with our camera. At 5: 00

p.m. we went home happily.

                                                                                                                                    Yours,

                                                                                                                                 Wang Qiang
