Because visual inspection cannot reliably distinguish certain skin discolorations from skin cancers, dermatologists at clinics have needed to perform tests of skin tissue taken from patients. At Westville Hospital, dermatological diagnostic costs were reduced by the purchase of a new imaging machine that diagnoses skin cancer in such cases as reliably as the tissue tests do. Consequently, even though the machine is expensive, a dermatological clinic in Westville is considering buying one to reduce diagnostic costs.

Which of the following would it be most useful for the clinic to establish in order to make its decision?

正确答案: C

GWD-17-23? 请NN回答!

1.         GWD-17-Q23

Because visual inspection cannot reliably distinguish certain skin discolorations from skin cancers, dermatologists at clinics have needed to perform tests of skin tissue taken from patients.  At Westville Hospital, dermatological diagnostic costs were reduced by the purchase of a new imaging machine that diagnoses skin cancer in such cases as reliably as the tissue tests do.  Consequently, even though the machine is expensive, a dermatological clinic in Westville is considering buying one to reduce diagnostic costs.

 

Which of the following would it be most useful for the clinic to establish in order to make its decision?

 

  1. Whether the visits of patients who require diagnosis of skin discolorations tend to be shorter in duration at the clinic than at the hospital
  2. Whether the principles on which the machine operates have been known to science for a long time
  3. Whether the machine at the clinic would get significantly less heavy use than the machine at the hospital does
  4. Whether in certain cases of skin discoloration, visual inspection is sufficient to make a diagnosis of skin cancer
  5. Whether hospitals in other parts of the country have purchased such imaging machines

 感觉C,D,E 都对, 到底选什么呢? 为什么?

是C,有两个词大家注意就容易理解这个题目了,Hospital医院和clinic门诊部 ,就像北京肿瘤医院和丰台区门头沟门诊部的区别。

如果是这样的区别,你觉得门头沟买这个设备能省钱吗?

这个题目出得太狡猾了!
题目说:一个医院买了这个机器,收到了效果;最后又说诊所也要买。问题问的是什么样的信息能够帮助诊所拿主意是否购买机器。
C说:要看看在诊所使用这样的机器频率是否跟医院差不多。这是一个好答案,因为题目中说了在医院收到了效果,那么如果在诊所也用得很多,那么一定是划算的。

做题目时,短时间内,往往可能分不清诊所和医院两个词语的来回使用

确实,这就是问题的关键!医院和诊所的就诊人数差别很大,购买同样的产品,均摊成本的差别也会很大!
