It is well established that surgical patients whose core body temperatures fall below 36 C (around 96.8 F) during surgery have much higher mortality rates than surgical patients whose core body temperatures remain above 36 C. Consequently, mortality rates could be significantly reduced during surgery if operating rooms were kept significantly warmer than they are presently kept under standard hospital guidelines, which call for temperatures of 21 C (around 69.8 F).


Which of the following, if true, argues most strongly against the view that surgical mortality rates could be reduced by raising operating room temperatures?

A. Surgical mortality rates are slightly higher during summer months than during winter months.

B. Delivery rooms tend to be kept at slightly higher temperatures than other operating rooms (around 24 C or 75.2 F) because premature babies are especially vulnerable to hypothermia.

C. It is more costly to maintain surgical equipment at temperatures above 21 C.

D. Nurses and medical technicians prefer working in room temperatures less than 24 C.

E. Manual dexterity and mental alertness tend to decline as the temperature rises above 21 C and more significantly so at temperatures above 24 C.

Let me try this one.

Conclusion: Mortality rates could be significantly reduced during surgery if operating rooms were kept significantly warmer than they are presently kept under standard hospital guidelines, which call for temperatures of 21 C
Premise 1:It is well established that surgical patients whose core body temperatures fall below 36 C (around 96.8 F) during surgery have much higher mortality rates than surgical patients whose core body temperatures remain above 36 C


Find the choice which says the even the temperatures raises the mortality rates keeps on raising or any other alternate case for the mortality


A. Surgical mortality rates are slightly higher during summer months than during winter months. - A bit strengthens

B. Delivery rooms tend to be kept at slightly higher temperatures than other operating rooms (around 24 C or 75.2 F) because premature babies are especially vulnerable to hypothermia. - Delivery room is not our concern

C. It is more costly to maintain surgical equipment at temperatures above 21 C. - Cost is not our factor, mortality rate is our only factor

D. Nurses and medical technicians prefer working in room temperatures less than 24 C. - This does not do any thing to say abt mortality rate

E. Manual dexterity and mental alertness tend to decline as the temperature rises above 21 C and more significantly so at temperatures above 24 C - Yes this weakens. Beacuse if the Manual dexterity and mental alertness decline, then the mortality rate will raise

As per you why in E it is assumed that manual dexterity causes mortality rate unless stated in argument. The manual dexterity might not call for death but could lead to failure of surgeries.

But in A, it clearly says in summer where normally high temperatures exists the mortality rate is higher than that in winter seasons. This weakens the conclusion.

But in original question it mentions that indoor temp is to be maintained at 21 C as per guidelines and is independent of the weather (Summer or Winter). Meaning even if its hot outside they still have to maintain it at 21 C and even if its freezing cold outside they have to maintain the room at 21 C.

IMHO E is most suitable as it mentions mental alertness tends to decline.

A. Surgical mortality rates are slightly higher during summer months than during winter months. irrelavant

B. Delivery rooms tend to be kept at slightly higher temperatures than other operating rooms (around 24 C or 75.2 F) because premature babies are especially vulnerable to hypothermia.again irrelevant

C. It is more costly to maintain surgical equipment at temperatures above 21 C.discussion is between temp. and mortality rate. - cost is not a factor

D. Nurses and medical technicians prefer working in room temperatures less than 24 C.prefrences are not related to surgical deaths and body temperature

E. Manual dexterity and mental alertness tend to decline as the temperature rises above 21 C and more significantly so at temperatures above 24 C.clearly shows that as temperature rises mental alertness of surgeons decreases and leads to higher deaths

The stem indicates that the answer choices will argue against the stimulus, so this is a Weaken question.

The stimulus states that operating rooms should be kept warmer than their current 21°C, since the mortality rate during surgery increases as body temperature decreases.

In order to weaken the proposal, find the answer choice that provides a disadvantage that the author may have overlooked.

If, as (E) asserts, manual dexterity and mental alertness go down as the operating room temperature is raised above 21°C, this would definitely weaken the plan to warm up the room. Few activities require more mental alertness and manual dexterity than performing surgery, so any potential gains that might be made by keeping patients warmer might be offset by the increased likelihood of surgical error.

(A) presents irrelevant information; there's no information about why surgical mortality rates are slightly higher in the summer, or even whether operating rooms are kept warmer or colder in the summer versus the winter.

(B) would, if anything, slightly strengthen the author's claim, because it suggests that some patients are very susceptible to cold, implying that warmer operating rooms would make sense.

(C) is completely irrelevant to the argument, as cost is not under consideration here.

(D) is also irrelevant to the argument. The concern here is with saving lives, not catering to the preferences of nurses and medical technicians.
