配制葡萄糖注射液加盐酸的目的是（）

A.增加稳定性

B.补充氯离子

C.抑制微生物

D.调整渗透压

E.去除银离子

答案

参考答案：A

解析：葡萄糖在酸性溶液中，首先脱水形成5-羟甲基呋喃甲醛，5-羟甲基呋喃甲醛进一步聚合而显黄色。影响本品稳定性的主要因素，是灭菌温度和溶液的pH。因此，为避免溶液变色，要严格控制灭菌温度与时间，同时调节溶液的pH在3.8～4.0，较为稳定。

Good afternoon, everyone. My talk for today is “Early Money”. I’m going to tell you something about money used in the early days. To tell you the truth, we know little about how early people came to use money, but we do know   some of the things which have been used as money. In early times in some   European countries, salt was very difficult to get, so it was used as money. In  some places of Asia, tea was used as money. The American Indians used nuts and other things. Perhaps the most common money of all was an animal of some kind. In some places today, cows are still used as a kind of money. So you see, things highly valued by everyday may serve as money.
