问题 单项选择题

成人伤寒患者,抗菌治疗首选下列何种药物()

A.氯霉素

B.第三代头孢菌素类

C.磺胺类

D.喹诺酮类

E.氨苄西林

答案

参考答案:D

解析:

这是一道记忆题。考核学生对伤寒病原治疗的掌握程度。预测错误率不高。常见错误:

①选答"A","氯霉素"对血象有较大影响,且有耐药现象,已不作伤寒的首选用药,应复习氯霉素药物的特点、疗效及副作用;

②选答"B","第三代头孢菌素类"副作用少,但需静脉给药,价格昂贵,故一般成人不作首选;

③选答"E","磺胺类"耐药率高,疗效不满意,不作首选。应复习上述几类药物的特点、疗效及副作用。要点上述几类药物均可用于伤寒的病原治疗,但喹诺酮类对伤寒杆菌抗菌作用强,目前耐药率不高,视为成人伤寒首选用药。

     All of my childhood and early adult life, my mom weighed over 220 pounds (one pound = 0.454

kilograms). I could feel the pain that my mom experienced with her fatness.

I was never uncomfortable about my mother, but I think she was uncomfortable about herself, and that

feeling was painful for all of us. And she began to lose weight.

     After more than twenty years of battling obesity(肥胖), my mother completed a forceful

eighteen-month diet that left her ninety pounds lighter than before. A new woman was born! At age

twenty-eight, I got a new mom! For the first time, I met the woman my mother truly was, the beautiful

little lady under the fatness. It wasn't so much her new body that was the surprise, but rather her new

spirit.

    To celebrate her new size and to devote herself to dancing again, my mother joined a "Mrs. Forty-Plus" competition, where she would have to model, give a speech and provide a dance performance. She told

our family that she did not care if she won - she simply had always wanted to perform on stage.

    She told each one of us, "I'm not doing it to win; I'm doing it to dance!"

    The competition was exciting! I prayed that my mom would win, but while watching her on stage I was

simply overjoyed just by her effort. To me, she had already won. She posed to perfection, her speech

brought tears to everyone's eyes, and her performance was wonderful.

    That night, at age fifty-three, my mother was crowned (为......加冕) "Mrs. Forty-Plus". She was the

first person in our family to ever win such a title.
