下列关于嵌顿性疝试行手法复位的指征,错误的是()。

A.婴幼儿嵌顿性斜疝4~6小时以内

B.年老体弱或伴有其他严重疾病,估计无肠坏死者

C.老年妇女的股疝嵌顿

D.病史长而疝块大的斜疝嵌顿

E.嵌顿时间在4小时以内

答案

参考答案:C

解析:嵌顿性疝试行手法复位的指征包括:①婴幼儿嵌顿性斜疝4~6h内;②年老体弱或伴有其他严重疾病,估计无肠坏死者;③病史长而疝块大的斜疝嵌顿;④嵌顿时间在4小时以内。而股疝多见于40岁以上的妇女。股疝通常较小,常在腹股沟韧带以下、卵圆窝处表现为一半球形突起,平卧还纳内容物后,疝块有时不完全消失,且疝囊颈狭小,咳嗽冲击感也不明显;股疝易发生嵌顿,除局部疼痛外,常伴有急性肠梗阻,所以老年妇女的股疝嵌顿不是手法复位的指征。故答案应选C。

     The latest research suggests that the key factor separating geniuses from the merely accomplished is not IQ,a generally bad predictor of success.Instead,it's purposeful practice.Top performers spend more hours practising their craft.If you wanted to picture how a typical genius might develop,you'd take a girl who

possessed a slightly above average language ability.It wouldn't have to be a big talent,just enough so that

she might gain some sense of distinction.Then you would want her to meet,say,a novelist,who

coincidentally shared some similar qualities.Maybe the writer was from the same town,had the same family background,or,shared the same birthday.

     This contact would give the girl a vision of her future self.It would give her some idea of a fascinating

circle she might someday join.It would also help if one of her parents died when she was 12,giving her a

strong sense of insecurity and fuelling a desperate need for success.Armed with this ambition,she would

read novels and life stories of writers without end.This would give her a primary knowledge of her field.

She'd be able to see new writing in deeper ways and quickly understand its inner workings.

     Then she would practice writing.Her practice would be slow,painstaking and error focused.By

practicing in this way,she delays the automatizing process.Her mind wants to turn conscious,newly learned skills into unconscious,automatically performed skills.By practicing slowly,by breaking skills down into tiny parts and repeating,she forces the brain to internalize a better pattern of performance.Then she would find an adviser who would provide a constant stream of feedback,viewing her performance from the outside,

correcting the smallest errors,pushing her to take on tougher challenges.By now she is redoing

problems-how do I get characters into a room-dozens and dozens of times.She is establishing habits of

thought she can call upon in order to understand or solve future problems.

     The primary quality our young writer possesses is not some mysterious genius.It's the ability to develop a purposeful,laborious and boring practice routine.The latest research takes some of the magic out of great achievement.But it underlines a fact that is often neglected.Public discussion is affected by genetics and

what we're "hard-wired" to do.And it's true that genes play a role in our capabilities.But the brain is also

very plastic.We construct ourselves through behaviour.
