问题 单项选择题 A1型题

患者女,25岁。妊娠37周,GP,因羊膜破裂入院待产。既往身体健康,无传染病及遗传性疾病史,分娩过程顺利,产一男婴7斤重。分娩后突然出现呼吸困难、发绀、抽搐、休克死亡。最可能发生的是()

A.血栓形成

B.空气栓塞

C.脂肪栓塞

D.心肌梗死

E.羊水栓塞

答案

参考答案:E

解析:

在活体的心脏或血管腔内,血液发生凝固或血液中的某些有形成分互相黏集,形成固体质块的过程,称为血栓形成,常发生于脑部及心脏,表现为心脑系统疾病,故排除A;空气栓塞是一种起源于肺的气体栓子阻塞脑血管引起的疾病,通常因在周围压力降低时膨胀的肺部气体导致肺过度膨胀所致,其常见的特征为疼痛和(或)神经系统症状,故排除B;脂肪栓塞是由于循环血流中出现的脂滴阻塞于小血管所致,常见于长骨骨折,严重脂肪组织挫伤或脂肪肝挤压伤时,脂肪细胞破裂,游离出的脂滴经破裂的小静脉进入血流而引起脂肪栓塞,故排除C。

心肌梗死是指急性、持续性缺血、缺氧所引起的心肌坏死。临床上多有剧烈而持久的胸骨后疼痛,休息及硝酸酯类药物不能完全缓解,故排除D。羊水栓塞是指在分娩过程中羊水突然进入母体血循环引起急性肺栓塞;胎膜早破是羊水栓塞发生的诱因,故选E。

    Many parents don't love to read to their children.But there are so many professionals and PhDs doing

the opposite thing.And they really promote reading to children, which is so good for children.I have found

that this is true with my own children.

     I am not sure if it is the book or the fact that you are spending quality time with them, undivided time

that they will remember for their entire life.Reading to children is one of the most bonding experiences you can have.

      Children enjoy sitting on your lap while your voice flows over them.As the reader it is fun to watch

their littl e faces as they are moved with the flow of the story.They are laughing one moment and on the

next page the story has moved them to tears.As the storyteller, I am just as moved as they are;I am

caught up in the story as our emotions flow up and down.You can easily lose a whole afternoon in reading.

      This is an experience that children then try to pass on to younger children, reading books to them.My

daughter was so into reading that if she couldn't line up some neighbors'children she could be reading her

books to, she would line up her stuffed animals and read to them.Well, she also tried to teach her neighbors and teddy bears math, and "ocean science "as she called it.She would read anything she could to them.

And to my astonishment the neighbors'parents told me they really appreciated the fact that their children

were doing so much better in school.
