Practice Question
Question No.: 45
Page: 134
Difficulty:

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.

Kind of confused but would go with "C".
just because it is the best out of the rest.

I am with E.

C also seems but it doesnot tell about what kind of X-rays of patients. In E, it tells Orthopedists routinely order follow-up x-rays for fractures of bone other than ankle bones.

No OA on this one - we will need to come to a consensus[/quote]

I pick C because when i read the argument, the first thing that i though of was 'was the survey big enough' which fits in with C.

anyway using POE:
A compares GPs and orthos....no relevance
B talks about injuries without fracture...no relevance
C tells you that the study was extensive and done in a variety of environments, thus strengthening the fact that you can make a generalised conclusion like the one above..
D tells you that followups are done...which doesnt strengthen the argument
E says that orthos do follow ups on other injuries too...this weakens the conclusion if anything...because if they do it for other things, why should they stop for ankles.

The only remaining answer is C

well thats my way of thinking in any case
obviously could be completely off

It's a confusing question.
I feel that C is the best choice because it strengthens the argument by stating that all the samples that passage is talking about were diverse and hence cannot be a coincidence.

I think the answer is B because it says that when initial injuries are x-rayed, they too are determined to have no fractures. the paragraph deals with follow up x-rays, but makes reference to the initial diagnosis.

i realize the person who posted it doesnt have the OA, but iÂ´ve seen this question published somewhere. Does anyone have this OA??

B is a scope shift. It deals with ankle injuries which is broader than ankle fractures.

I also pick C after POE.

I would go with A
From the passage we know that an orthopedist's judgment about the stability of an ankle is correct. Based on this a sweeping conclusion is made saying that follow-up x-rays are a waste of money. One way to strengthen this will be as in A which says general practitioners are less likely to pass judgment about the stability of an ankle which means only orthopedists do so.

I think A weakens the argument in explaining why there could have an interest to make some X-ray follow up...

I do not think A weakens the argument.
The passage talks about orthopedists judgement and based on that it makes a conclusion that x-rays are a waste of money.
The assumption underlying this conclusion is that only orthopedists pass judgement - which is what A states explicitly.

My vision of the stem was :

Even orthos who are the best able to judge if a fracture will heal correctly or not are prescribing some xray even unnecessarily

Doctors are less likely than orthopedists to judge the stability of an ankle fracture correctly : why does it strengthen there is no more need of follow up whereas doctors are less experienced in that matter ?

Moreover I guess it is a scope shift introducing a new category.

I would go with C. This is talking about how the sample is well represented. And hence, strengthens the finding.

C.

The strongest one should be the one to say that the review done has the best representation of all cases.

why not 'A' ?

If orthopedists judge the fractures correctly, then there is no need for X-rays. <== strengthens

What is wrong with this reasoning ?
