A.Ⅰ类甲级
B.Ⅰ类乙级
C.Ⅱ类甲级
D.Ⅱ类乙级

答案

参考答案:D

解析: 对于初期完全缝合的切口,拆线时应记录切口愈合情况,可分为三类:①清洁切口(Ⅰ类切口),指缝合的无菌切口,如甲状腺大部切除术等。②可能污染切口(Ⅱ类切口),指手术时可能带有污染的缝合切口,如胃大部切除术等。皮肤不容易彻底消毒的部位、6h内的伤口经过清创术缝合、新缝合的切口再度切开者,也属此类。③污染切口(Ⅲ类切口),指邻近感染区或组织直接暴露于污染或感染物的切口,如阑尾穿孔的阑尾切除术、肠梗阻坏死的手术等。切口的愈合也分为三级:①甲级愈合,用“甲”字代表,指愈合优良,无不良反应。②乙级愈合,用“乙”字代表,指愈合处有炎症反应,如红肿、硬结、血肿、积液等,但未化脓。③丙级愈合,用“丙”字代表,指切口化脓,需要作切开引流等处理。

单项选择题

The Southdale shopping centre in Minnesota has an atrium, a food court, fountains and acres of parking. Its shops include a Dairy Queen, a Victoria’s Secret and a purveyor of comic T-shirts. It may not seem like a landmark, as important to architectural history as the Louvre or New York’s Woolworth Building. But it is. "oh, my god!" chimes a group of teenage girls, on learning that they are standing in the world’s first true shopping mall. "That is the coolest thing anybody has said to us all day. "

In the past half century Southdale and its many imitators have transformed shopping habits, urban economies and teenage speech. America now has some 1,100 enclosed shopping malls, according to the International Council of Shopping Centres. Clones have appeared from Chennai to Martinique. Yet the mall’s story is far from triumphal. Invented by a European socialist who hated cars and came to deride his own creation, it has a murky future. While malls continue to multiply outside America, they are gradually dying in the country that pioneered them.

Southdale’s creator arrived in America as a refugee from Nazi-occupied Vienna. Victor Gruen was a Jewish bohemian who began to design shops for fellow immigrants in New York after failing in cabaret theatre. His work was admired partly for its uncluttered, modernist look, which seemed revolutionary in 1930s America. But Gruen’s secret was the way he used arcades and eye-level display cases to lure customers into stores almost against their will. As a critic complained, his shops were like mousetraps. A few years later the same would be said of his shopping malls.

By the 1940s department stores were already moving to the suburbs. Some had begun to build adjacent strips of shops, which they filled with boutiques in an attempt to re-create urban shopping districts. In 1947 a shopping centre opened in Los Angeles featuring two department stores, a cluster of small shops and a large car park. It was, in effect, an outdoor shopping mall. Fine for balmy southern California, perhaps, but not for Minnesota’s harsh climate. Commissioned to build a shopping centre at Southdale in 1956, Gruen threw a roof over the structure and installed an air-conditioning system to keep the temperature at 75°F (24℃)—which a contemporary press release called "Eternal Spring". The mall was born.

Gruen got an extraordinary number of things right first time. He built a sloping road around the perimeter of the mall, so that half of the shoppers entered on the ground floor and half on the first floor-something that became a standard feature of malls. Southdale’s balconies were low, so that shoppers could see the shops on the floor above or below them. The car park had animal signs to help shoppers remember the way back to their vehicles. It was as though Orville and Wilbur Wright had not just discovered powered flight but had built a plane with tray tables and a duty-free service.

According to the text, which of the following is TRUE()

A. Southdale will be closed soon

B. Shopping malls are flourishing all over the world

C. After long time of prosperity, shopping malls in US is gradually declining

D. Shopping mall is an American creation
