开放性创口止血注意事项

答案

参考答案:

1.止血带绕扎部位:扎止血带的标准位置在上肢为上臂上1/3,下肢为股中、下1/3交界处。目前有入主张把止血带扎在紧靠伤口近侧的健康部位,有利于最大限度地保存肢体,上臂中、下1/3部扎止血带容易损伤桡神经,应视为禁区。

2.扎止血带的松紧要合适,压力是使用止血带的关键问题之一。止血带的松紧,应该以出血停止、远端不能摸到脉搏为度。过松时常只压住静脉,使静脉血液回流受阻,反而加重出血。使用充气止血带,成人上肢需维持在40kPa(300mmHg),下肢以66.7kPa(500mmHg)为宜。

3.持续时间原则上应尽量缩短使用止血带的时间,通常可允许1小时左右,最长不宜超过3小时。

4.止血带的解除:要在输液、输血和准备好有效的止血手段后,在密切观察下放松止血带。若止血带缠扎过久,组织已发生明显广泛坏死,截肢前不宜放松止血带。

5.止血带不可直接缠在皮肤上,扎止血带的相应部位要有衬垫,如三角巾、毛巾、衣服等均可。

6.要求有明显标志,说明扎止血带的时间和部位。

Questions 16-20 are based on the following passage.
What is intelligence, anyway When I was in the army, I received a kind of aptitude test that all soldiers took and, against a normal of 100, scored 160. No one at the base had ever seen a figure like that, and for two hours they made a big fuss over me. (It didn’t mean anything. The next day I was still a buck private with KP—kitchen police—as my highest duty. )
All my life I’ve been registering scores like that, so that I have the complacent feeling that I’m highly intelligent, and I expect other people to think so, too. Actually, though, don’t such scores simply mean that I am very good at answering the type of academic questions that are considered worthy of answers by the people who make up the intelligence tests—people with intellectual bents similar to mine
For instance, I had an auto-repair man once, who, on these intelligence teste, could not possibly have scored more than 80, by my estimate. I always took it for granted that I was far more intelligent than he was. Yet, when anything went wrong with my car I hastened to him with it, watched him anxiously as he explored its vitals, and listened to his pronouncements as though they were divine oracles—and he always fixed my car.
Well, then, suppose my auto-repair man devised questions for an intelligence test.Or suppose a carpenter did, or a farmer, or, indeed, almost anyone but an academician. By every one of those thests, I’d prove myself a moron. And I’d be a moron, too. In the world where I could not use my academic training and my verbal talents but had to do something intricate or hard, working with my hands, I would do poorly. My intelligence, then, is not absolute but is a function of the society I live in and of the fact that a small subsection of that society has managed to foist itself on the rest as an arbiter of such matters.
Consider my auto-repair man, again. He had a habit of telling me jokes whenever he saw me. One time he raised his head from under the automobile hood to say: "Doc, a deaf-and-mute guy went into a hardware store to ask for some nails. He put two fingers together on the counter and made hammering motions with the other hanD.The clerk brought him a hammer. He shook his head and pointed to the two fingers he was hammering. The clerk brought him nails. He picked out the sizes he wanted, and left. Well, doc, the next guy who came in was a blind man. He wanted scissors. How do you suppose he asked for them "
In dulgently, I lifted my fight hand and made scissoring motions with my first two fingers. Whereupon my auto-repair man laughed and said, "Why, you dumb jerk, he used his voice and asked for them. " Then he said smugly, "I’ve been trying that on all my customers today. " "Did you catch many " I askeD."Quite a few," he said, "but I knew for sure I’d catch you. " "Why is that " I askeD."Because you’re so goddamned educated, Doc, I knew you couldn’t be very smart. "
And I have an uneasy feeling he had something there.

By calling his assignment to KP as "my highest duty", the author suggests that______.

A.KP is an important position in the army every soldier desires

B.KP is a job of manual labor which does not require a special level of intelligence

C.KP is his most important job in the army

D.he is proud of his position as KP
