问题 单项选择题

女,6岁,烧伤50%,Ⅲ度20%,体温37℃,脉搏146次/分,呼吸36次/分,创面可见坏死斑,血培养为阴沟杆菌

A.X线腹片见肠壁串珠状透亮区
B.X线腹片见上腹部双泡征
C.X线腹片见上腹部三泡征
D.X线腹片见一大液平
E.X线腹片见腹腔空白伴双泡征

答案

参考答案:A

解析:[解题思路] 1.潮湿的创面、局灶性积脓及创面周围炎症明显,血培养无病源菌的生长,故菌血症的诊断标准都不能满足,伤后10天有高体温只能是创面脓毒症。2.烧伤50%,创面可见坏死斑,血培养为阴沟杆菌,说明是革兰阴性杆菌引起的菌血症,但伤后有低体温,心率快等表现则应诊断为烧伤败血症更确切。

     Are you happy? Do you remember a time when you were happy? Are you seeking happiness today?

     Many have sought a variety of sources for their feeling of happiness.Some have put their heart and

efforts into their work.Too many turned to drugs and alcohol.Meanwhile, untold numbers have looked for

it in the possession of expensive cars, exotic (异国的) vacation homes and other popular "toys". Most of

their efforts have a root in one common fact: people are looking for a lasting source of happiness.

     Unfortunately, I believe that happiness escapes from many people because they misunderstand the

journey of finding it.I have heard many people say that, "I'll be happy when I get my new promotion."

or "I'll be happy when I lose that extra 20 pounds." It is dangerous because it accepts that happiness is a

"response" to having, being or doing something.

     In life, we all experience stimulus (激励) and response.Today, some people think that an expensive

car is a stimulus.Happiness is a response.A great paying job is a stimulus.Happiness is a response.This

belief leaves us thinking and feeling, "I'll be happy when..."

     It has been my finding that actually the opposite is true.I believe that happiness is a stimulus and

response is what life brings to those who are truly happy.When we are happy, we tend to have more

success in our work.When we are happy, we more naturally take better care of our bodies and enjoy

good health.Happiness is not a response but a stimulus.

     Happiness is a conscious choice we make in daily life.For unknown reasons to me, many choose to

be upset and angry most of the time.Happiness is not something that happens to us after we get something we want-we usually get things we want after we choose to be happy.
