问题 多项选择题

保钾利尿剂有()。

A.呋赛米

B.螺内酯

C.氨苯喋啶

D.双氢克尿噻

E.依他尼酸

答案

参考答案:B, C

解析:保钾利尿剂常用的有:①螺内酯(安体舒通):作用于肾远曲小管,干扰醛固酮的作用,使钾离子吸收增加,同时排钠利尿,但利尿效果不强。在与噻嗪类或袢利尿剂合用时能加强利尿并减少钾的丢失,一般用20mg,每日3次。②氨苯蝶啶:直接作用于肾远曲小管,排钠保钾,利尿作用不强。常与排钾利尿剂合用,起到保钾作用,一般50~100mg,每日2次。③阿米洛利(amiloride):作用机制与氨苯蝶啶相似,利尿作用较强而保钾作用较弱,可单独用于轻型心衰的患者,5~10mg,每日2次。

                                        How to Become a Better Student

                                            

     Maybe you are an average student.You probably think you will never be a top student.

This is not necessarily so,however.Anyone can become a better student if he or she wants

to.Here is how.

     Plan your time carefully.

     When planning your week,you should make a list of things that you have to do.After

making the list,you should make a schedule of your time.First arrange your time for eating,

sleeping,dressing,etc..Then decide a good,regular time for studying.Don’t forget to

set aside enough time for entertainment.A weekly schedule may not solve all the problems,

but it will force you to realize what is happening to your time.    

     Find a good place to study.

     Look around the house for a good study area.Keep this place,which may be a desk

or simply a corner of your room,free of everything but study materials.No games,

radios or TV!When you sit down to study,concentrate on the subject.

     Make good use of your time in class.

     Take advantage of class time to listen to everything the teacher says.Really listening in

class means less work later.Taking class notes will help you remember what the teacher says.

     Study regularly.When you get home from schools,go over your notes.Review the

important points that your teacher has mentioned in class.If you know what your teacher is

going to discuss the next day,read the material.This will help you understand the next

class.If you do these things regularly,the material will become more meaningful,and you

will remember it longer.

     Develop a good attitude about the tests.The purpose of a test is to show what you

have learned about a subject.They help you to remember your new knowledge.The world

won’t end if you don’t pass a test,so don’t be overly worried.There are other methods that

might help you with your studying.You will probably discover many others after you have

tried these.
