问题 单项选择题 A1/A2型题

女性,46岁。临床诊断右乳腺癌行乳腺癌根治术。既往有高血压病史。术后出现BP220/120mmHg,HR125bpm,CVP18mmHg,气管导管中涌出大量的粉红色泡沫样分泌物。药物处理应首先选用()。

A.强心剂

B.利尿剂

C.利尿剂+血管扩张剂

D.血管扩张剂

E.强心剂+利尿剂+血管扩张剂

答案

参考答案:C

解析:此种情况应首先应用利尿剂和血管扩张剂,而不应首先选用强心剂,因为左心室的后负荷已经很重,如首先应用强心剂,可能会导致左心做功增加,加重左心功能的衰竭。应用利尿剂和血管扩张剂明显减轻左心的前负荷后,可考虑适量应用强心剂。

My baby Rob, the youngest of my three sons, was starting kindergarten. I had already 36 this twice before, but this time it was more difficult.

What if he was scared? What if he missed me? I decided to do the grown-up thing and not tell him how I 37. I assured him that 38 would be just fine. 

The night 39 school started, Rob and I sat down. I hugged him and asked if he had any questions about what he could expect tomorrow ... “I’m 40 excited, Mommy, but I’m a little 41 about what I should do 42 I miss you,” he said sheepishly (胆怯地).

I had just the 43 for him.

I 44 my hand and showed him a new, shiny penny. “This is a 45 magic penny. If you’re scared or if you 46 me, just put your hand in your pocket and 47 this lucky penny. 48 you hold it and 49 me, I will know and be thinking about you , too.”

It was absolutely 50. I’d be thinking about him every minute.

The next day as he 51 his schoolroom, he looked back at me. My baby looked so sure of himself. I smiled back at him and hoped that he didn’t see the 52 in my eyes.

The hours moved slowly but finally it was time to pick him 53. “I had a great day!” he 54. “There were a few times I was worried, but I held on to my lucky penny and that made me feel better.”

After about a week I found it on his dresser.  I guessed he was secure enough in his new situation that he didn’t 55 it anymore.

I, on the other hand, kept it in my pocket for a few more days.
