Often patients with ankle fractures that are stable, and [#permalink] New post 04 Aug 2007, 20:09
Often patients with ankle fractures that are stable, and thus do not require surgery, are given follow-up x-ray because their orthopedists are concerned about possibly having misjudged the stability of the fracture. When a number of follow-up x-rays were reviewed, however, all the fractures that had initially been judged stable were found to have healed correctly. Therefore, it is a waste of money to order follow-up x-rays of ankle fracture initially judged stable.

Which of the following, if true, most strengthens the argument?

A) Doctors who are general practitioners rather than orthopedists are less likely than orthopedists to judge the stability of an ankle fracture correctly.
B) Many ankle injuries for which an initial x-ray is ordered are revealed by the
x-ray not to involve any fracture of the ankle.
C) X-rays of patients of many different orthopedists working in several hospitals were reviewed.
D) The healing of ankle fractures that have been surgically repaired is always
checked by means of a follow-up x-ray.
E) Orthopedists routinely order follow-up x-rays for fractures of bone other than ankle bones.

Conclusion: it is a waste of money to have patients get follow up x-rays for ankle fracture initially judged stable.
Therefore, if the initial x-ray is good, then doing follow ups would be unnecessary. Answer B states this and strengthens the argument.

Overlooked the question that it is asking to strnghten the argument.. Also had difficulty understand B.
Yes B is the right ans when it says that ankle fractures are revealed by the x-rays that are meant for simple injuries.. means ankle fractures are easily easily detected. making follow-up x-ray redundant..

Why is it B? The conclusion states that, "it is a waste of money to order follow-up x-rays of ankle fracture initially judged stable." The conclusion states that the ankle is already fractured, which means that answer B is out of scope as its subject is about "many ankle injuries" in a broad sense (and not just to those pertaining to ankle fractures).

I think the answer is C because the conclusion is based upon a review of "a number of follow-up x-rays." I think the question pertains to the issue of sample size and accuracy. If (as it is with answer choice C), the sample was drawn from several sources, then the findings from the sample size become less biased and more robust which would then strengthen the conclusion.

Good point...this is a question based on strengthening the sample...C it is.

great explanation.. I was not even looking at the argument correctly... these strengthen the argument questions can be so tricky!

A - Additional information irrelevant to the discussion
B - Additional information that strengthens the discussion - keep
C - Additional information that strengthens the discussion (to a lesser extent) - keep
D - Info. out of scope - talking about ankle fractures that are surgically reparied.
E - Not relevant.

Between B and C, I choose B. Wait for your responses. Thanks

I go for B.

A: Irrelevant we want to know why x-rays are NOT needed after the initial diagnosis.
C:I don't see how this is even remotely relevant. This doesn't help explain why x-rays are NOT needed...
D: Irrelevant we are concerned with non-surgery ankle fractures.
E:restates passage, doesn't strengthen or weaken.

Assumption: Ankle fracture judged stable - is diagnosed accurately so doesnt require any follow up x-rays

A seems close to tht....

C - It confirms that the follow up xrays that were reviewed are not from an isolated orthopedist and are representative of the industry.

E weakens the argument.

If they are doing follow up xrays for a reason other then checking the intitial fracture then assumption linking the premise and the conclusion is destroyed.

premise: follow up xrays are found to have a healed fracture, and the conclusion: therefore, follow up xrays shouldnt be done.
assumption: follow up xrays are done only to check the initial fractutre.
Weaken: Xrays are done for a reason other then checking the initial fracture
