问题 单项选择题

可致心律失常的是()

A.异丙托溴铵

B.茶碱

C.乙酰半胱氨酸

D.氨溴索

E.布地奈德

答案

参考答案:B

解析:

本题考查平喘药的不良反应。异丙托溴铵雾化时应防止雾化液和药粉接触患者的眼睛。如药品在使用中不慎污染眼睛,引起眼睛疼痛或不适、视物模糊、结膜充血和角膜水肿并视物有光晕或有色成像等闭角型青光眼的征象,应首先使用缩瞳药并即就医。

糖皮质激素雾化时常见口腔及咽喉部的念珠菌定植与感染(鹅口疮)、声音嘶哑、咽喉部不适,应及时漱口。布地奈德是一种吸入激素,可导致口腔念珠菌感染。茶碱类药可致心律失常,使原有的心律失常恶化,尤其是静脉注射过快或茶碱血浆浓度高于20μg/ml时,可出现严重毒性反应,表现为心律失常、心率加快、肌肉颤动、癫痫、一过性低血压或周围循环衰竭,因此应监测茶碱血药浓度。

单项选择题

Humans are social animals. They live in groups all over the world. As these groups of people live apart from other groups, over the years and centuries they develop their own habits and ideas, which form different cultures. One important particular side of every culture is how its people deal with time.
Time is not very important in non-industrial societies. The Nuer people of East Africa, for example, do not even have a word TIME that is in agreement with the abstract thing we call time. The daily lives of the people of such non-industrial societies are likely to be patterned around their physical needs and natural events rather than around a time schedule based on the clock. They cook and eat when they are hungry and sleep when the sun goes down. They plant crops during the growing seasons and harvest them when the crops are ripe. They measure time not by a clock or calendar, but by saying that an event takes place before or after some other events. Frequently such a society measures days in terms of "sleeps" or longer periods in terms of "moons". Some cultures, such as the Eskimos of Greenland measure seasons according to the migration of certain animals.
Some cultures which do not have a written language or keep written records have developed interesting ways of "telling time". For example, when several Australian aborigines want to plan an event for a future time, one of them places a stone on a cliff or in a tree. Each day the angle of the sun changes slightly. In a few days, the rays of the sun strike the stone in a certain way. When this happens, the people see that the agreed-upon time has arrived and the event can take place.
In contrast, exactly correct measurement of time is very important in modern, industrialized societies. This is because industrialized societies require the helpful efforts of many people in order to work. For a factory to work efficiently (well, quickly and without waste), for example, all of the workers must work at the same time. Therefore, they must know what time to start work in the morning and what time they may go home in the afternoon. Passengers must know the exact time that an

The Australian aborigines’ way of "telling time" is based on ______.

A. the change of the sun rays
B. the movement of the earth in relation to the sun
C. the position of the stone
D. the position of the tree or the cliff
