下列关于ARDS进展期临床表现的叙述,错误的是

A.明显发绀

B.呼吸道分泌物多

C.意识可发生障碍

D.肺部有哕音

参考答案:E

解析:ARDS是危重疾病时并发的“急性呼吸衰竭”。进展期时病人有明显的呼吸困难和发绀,呼吸道分泌物增多,肺部有哕音,可有意识障碍如烦躁、谵妄或昏迷。X线胸片有广泛性点、片状阴影。所以说X线胸片无明显异常是不对的。

it instantly by putting the noodles into the boiling water and add in those MSG (味精) packets, together with

your other food like eggs or vegetables. However, have you ever wondered whether this is the correct way

of cooking it? When you first took out the noodles from the packaging, you will notice that the noodles are

joined together nicely as a piece. In order to make the noodles joined together nicely side by side it needs some

form of wax coating (石蜡涂层) in order to show an attractive instant noodles in front of us. Many people

who enjoy eating instant noodles frequently do not really think too much of it as it seems very normal to

everyone to have it nicely shown in front of us. However, researches have shown that the wax coating on

the noodles is quite harmful to our body and we should not eat it too frequently. It is advisable to have a break

of 2-3 days before we start to eat another packet of instant noodles as our body need about 3 days to clear that

layer of wax coating away from our body system. Do you know the danger of having too much wax coating
