※ 引述《heine564 (築夢踏實)》之銘言: : Treatment for hypertension forestalls certain medical expenses by preventing : strokes and heart disease. Yet any money so saved amounts to only one-fourth : of the expenditures required to treat the hypertensive population. : Therefore, there is no economic justification for preventive treatment for : hypertension. : Which of the following, if true, is most damaging to the conclusion above? 問weaken。 主要結論在"therefore"後面:預防高血壓'在經濟上'不划算。 題目告訴我們: 預防治療省的醫療費用 是 預防治療費用 的 1/4 省的錢比費用少所以經濟上不合理。 看完之後發現一時間找不出邏輯上的缺陷。所以直接果斷看選項。 : (A) The many fatal strokes and heart attacks resulting from untreated : hypertension cause insignificant medical expenditures but large economic : losses of other sorts. 或許不治療所引發的醫療費用不多,但是可能有其他方面的經濟損失, 比如家庭受影響、失去工作...... 這些錢都要算在經濟層面考慮噢, 所以就算醫療費用很少,但是其他經濟損失很大的話, 做預防還是經濟上划算的。 : (B) The cost, per patient, of preventive treatment for hypertension would : remain constant even if such treatment were instituted on a large scale. 就算scale改變,成本仍然維持constant,省的錢仍然無法超越成本。X : (C) In matters of health care, economic considerations should ideally not be : dominant. 本題的結論只考慮經濟層面,C選項直接超出範圍。X : (D) Effective prevention presupposes early diagnosis, and programs to ensure : early diagnosis are costly. 說預防包括早期診斷,早期診斷還是costly的, 隱含的意思是預防很貴,那就更不可能經濟划算了。 X : (E) The net savings in medical resources achieved by some preventive health : measures are smaller than the net losses attributable to certain other : measures of this kind. 文章裡沒有把預防跟其他方法做比較,無關。X : 不懂為什麼答案是(A) : 這樣理解對嗎? 如果不去treat hypertension的話 會造成其他類別的疾病更大的損失 : 所以去treat hypertension 還是有他的contribution在的 注意economic是指所有金錢損益層面,不只是醫療費用噢。 希望有解決到你的問題。 Dustin -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 1.162.23.21
