问题 单项选择题

伴有糖尿病的水肿患者,不宜选用哪种利尿药:

A.螺内酯

B.氢氯噻嗪

C.依他尼酸

D.乙酰唑胺

E.布美他尼

答案

参考答案:B

解析:[解题思路] 利尿药对代谢的影响。对代谢有影响的利尿药主要是噻嗪类利尿药,与剂量有关,可致高血糖、高脂血症。本类可降低糖耐量,使血糖升高,可能是抑制了胰岛素的分泌或抑制肝的磷酸二酯酶,因此使cAMP中介的糖原分解作用加强,糖尿病患者慎用。备选答案中只有氢氯噻嗪属于噻嗪类利尿药,应该掌握。

Mount Kilimanjaro is the highest mountain in Africa and one of the largest free-standing mountains in the world, and some say, the most beautiful place on the earth.

The mountain towers 15,000 feet above the plains. Mount Kilimanjaro is in Tanzania and it covers an area of 60 miles long and 40 miles wide. Kilimanjaro is an extinct volcano(死火山), with 3 peaks. Kibo is the highest one in the center.

Because of Kilimanjaro's great height, the mountain influences(影响) its own weather. Winds incoming from the Indian Ocean are stopped upward by the mountain and drop their moisture(湿气) as rain and snow. People have planted coffee, corn, and other crops on the lower slopes(斜坡).

Mount Kilimanjaro now attracts many thousands of walkers each year. Because of a temperature rise in recent years, the beautiful snow cap of Kilimanjaro is retreating(消退) fast. A research said that the white snow on the mountain might be gone in 15 years. What a pity!
