问题 单项选择题

对有呼吸功能障碍病人手术前准备,不正确的是

A.停止吸烟2周,练习深呼吸
B.手术前使用抗生素
C.有哮喘病史,可口服地塞米松
D.减少气管分泌,阿托品用量加大
E.避免呼吸抑制,少用吗啡

答案

参考答案:D

解析: 阿托品能松弛许多内脏平滑肌,对过度活动或痉挛的内脏平滑肌,松弛作用较显著。阿托品因阻断M胆碱受体而抑制腺体分泌,唾液腺和汗腺最敏感,在用0.5mg阿托品时,就显著受抑制,引起口干和皮肤干燥,同时泪腺和呼吸道分泌也大为减少,所以不可加大阿托品的用量。故答案应选D。

2008 sadly saw the worst earthquake in China in over 30 years. The Great Sichuan Earthquake was 8 on the Richter scale and killed around 70,000 people in May, not to mention the tens of thousands who were injured or went missing.

On 26th January, 2009, the biggest earthquake in India took the lives of 25,000 people. In the morning, when everybody was enjoying holiday, the earthquake began, It was about 7.5 on the Richter scale. "There is nothing left between the sky and the earth any more. Everything has been pulled down. " said one of the villagers alive. " There is no water, no food and no one has come to help."

Nobody died in Pakistan, a country next to India. The City of Lahore was lucky. In Lahore American School, where I was studying, all of the students were safe. They were in the field, so most children didn't feel anything. The earthquake was felt by the teachers that were on the second floor. However, though Mrs Young was also on the second floor, she didn't feel anything. She didn't know what happened until a teacher told her about it. Those teachers who were on the other floors had different feelings. Mr Emond, the maths teacher from Australia, said that when the earthquake started he thought there was something wrong with him, but then another teacher said that it was an earthquake. After those words Mr Emond felt better. Mrs Davis and Mr Frost didn't feel anything either.

My mother didn't feel anything. She didn't even know that it was an earthquake till she saw a shaking light. My dad saw the computer shaking and then he looked out of the window and saw many people going out.
