问题 单项选择题 A1/A2型题

对于格林-巴利综合征病人,不属于使用呼吸机指征的是()

A.肺活量降至每公斤体重20~25ml以下

B.血氧饱和度降低

C.病人出现呼吸费力、烦躁、出汗、口唇发绀等缺氧症状

D.动脉血氧分压低于70mmHg

E.静脉血氧饱和度(SPO2)<97%

答案

参考答案:E

解析:格林-巴利综合征的病人,要严密监测病情严密观察病人的呼吸、肺活量、血气分析的变化,观察病人有否呼吸费力、烦躁、出汗、口唇发绀等缺氧症状,肺活量降至每公斤体重20~25ml以下,血氧饱和度降低,静脉血氧饱和度(SPO2)<90%,动脉血氧分压低于70mmHg,宜及早使用呼吸机,并加强呼吸机的管理。其中,静脉血氧饱和度(SPO2 )的正常值为96%~100%,所以"静脉血氧饱和度(SPO2)<97%"是错误的。

Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don’t agree with them.

Waste can bring a lot of problems. Although China is rich in some resources(资源), we are short of(缺乏)others, for example,fresh water(淡水). It is reported that we will have no coal(煤or oil to use in 100 years. So if we go on wasting our resources,what can we use in the future and where can we move?Think about it. I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.

In our everyday life,we can do many things to prevent waste from happening,for example, turn off the water taps(水龙头) when we finish washing,turn off the lights when we leave the classroom,try not to order more food than we need and so on. Little by little, everything will be changed. Waste can be stopped one day, if we do our best.
