A.洋地黄类药物静脉推注

B.快速利尿剂静脉推注

C.呼气末正压通气

D.加强抗感染

E.输血

答案

参考答案:C

解析:考点:急性呼吸窘迫综合征的治疗,ARDS治疗的需治疗原发病,如处理好创伤,迟早找到感染灶,针对病原菌应用敏感的抗生素,制止炎症反应进一步对肺的损伤;但更紧迫的是要及时纠正患者严重缺氧,赢得治疗基础疾病的宝贵时间。在呼吸支持治疗中,为防止感染,应采取无创通气纠正其低氧血症。所以本题患者应采用呼气末正压通气治疗。所以本题选C。

    If you don't use your arms or your legs for some time, they will become weak; when you start using them

again, they will gradually (逐渐地) become stronger again. Everybody knows this. Yet many people do not

seem to know that it is the same with our memory.   

    If a friend says that his arms and legs are weak, we know that it is his own fault. But if he tells us that he

has a poor memory, many of us think that his parents are to blame (责怪), and few of us know that it is just

his own fault.   

    Have you ever found that some people can't read or write but they usually have better memories? This is

because they can not read or write and they have to remember things; they can not write them down in a little

notebook. They must remember dates, names, songs and stories; so their memories are being exercised the

whole time.   

    So if you want a good memory, learn from these people: practice remembering.
