问题 单项选择题 A1/A2型题

某肺癌患者接受化疗,护士静脉推注阿霉素20mg+生理盐水20ml时。不慎将药液漏至血管外。以下哪项处理错误()。

A.停止注射,拔出针头

B.支托痛处

C.普鲁卡因注入局部皮下

D.局部热敷

E.氢化可的松油膏外敷

答案

参考答案:D

解析:阿霉素渗出血管外可造成局部组织严重坏死,应紧急停药,拔出针头,普鲁卡因注射既可以稀释外漏的药液和阻止药液的扩散,24h内可以用冰袋局部冷敷,冷敷可使血管收缩,减少药液向周围组织扩散。热敷加快药物吸收。故本题选D。避错:本题主要考察考生对化疗药物外渗的护理。药物外渗一旦发生,要保持镇静,立即停止输注,保留注射针头,回抽残留药物以3~5ml为宜,还要沿血管走行观察和了解血管情况,采取积极有效的治疗措施,消除组织水肿和药物对细胞的毒性作用。立即行局部封闭,皮下注射利多卡因。局部涂氢化可的松软膏或者50%的硫酸镁湿敷或冰敷(24h内),抬高患肢,24h后改为热敷。故本题选D。

Brazil is a federation that consists of twenty-six states and one federal district. The biggest majority of Brazil’s population belongs to the Christian religion and almost all of them are Catholics. This is something Brazil inherited(继承) being Portugal’s colony(殖民地).

Historically, the country was a colony claimed by people from Portugal and this made Portuguese the official language. The Portuguese reached Brazil in 1500 and until that moment it was inhabited by semi-nomadic(半游牧的) people. The Portuguese changed Brazil into a country of slaves until 1800, when Maria I of Portugal came to live to Brazil. The Queen did not stay long in Brazil, but during the 20 years of royal presence a lot of changes occurred: commercial ports to United Kingdom were opened; Brazil stopped being isolated(孤立) from other countries. So at the moment of getting the independence on the 7th of September, 1822, Brazil already had the potential to develop. The Brazilian Empire, Pedro I, abolished slavery in 1888 in the face of Princess Isabel. A lot of European people started coming to Brazil and the industry of the country started working. In the 19th and the 20th century as it has been said above foreign people immigrated(移民) to Brazil and basically 5 million European and Japanese people became the residents of Brazil. The beginning of the 20th century was especially marked by the immigration of a lot of Asian people: Japanese, Korean and Chinese immigrants. As a matter of fact Japanese people do not immigrate a lot, and the fact that the Brazilian-Japanese people are the largest Japanese minority in the world does astonish greatly.

The majority of the cultural inherits of Brazil are actually Portuguese, due to the fact that Brazil was Portugal’s colony for a very long time. The southern states mainly consist of European population and the north and the northeast consist of a mixed population including Africans, Amerindians and Europeans. Most of this population is Roman Catholic. No other country in the world has the same amount of Catholics. The modern tendency of Brazil is the growing number of people calling themselves Protestants. Around 7.4% of the population don’t believe any god. Some Brazilians, especially in the northern states are mixed Africans who prefer following the traditional African religions. Only 1.8% of the population chose Buddhism, Islam or Judaism.

Though Brazil always tried to maintain democracy, it was failed several times by the dictatorship(独裁) of Getulo Vargas. This fact could not affect the political situation in the country.
