Often patients with ankle fractures that are stable, and [#permalink]
 27 Dec 2006, 20:38
Question Stats:
0% (00:00) correct
 0% (00:00) wrong based on 0 sessions
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.

choice C
X-rays of patients of many different orthopedists working in several hospitals were reviewed.
this suggests the x-rays were conducted on a widespread basis,thus helping the conclusion.

I'd say C.
More reviews, stronger argument.

THough C looks good to me, I'm slightly lean towards B.
Reason: B refers completely about the ankle fracture and that is the argument to strengthen here.

C
B is explicitly mentioned in the para ... and C strengthens the argument by showing records of different orthopedist and hospitals .. all are revealing the same result

C. Shows that the results of the study were a representative sample of ankle fractures.
B was a contender but it is referring to initial x-rays. We dont care about the initial x-ray, only about whether the follow up x-rays are necessary. I think choosing B would require a large stretch to make it relevent to the actual arg. therefore incorrect.
OA?

it has to be C, The way to strengthen this argument is to strengthen the reliability of the evidence. If this is not included, it could have just been just one doctor at one hospital who misjudged all the diagnosis. Knowing there is a representative sample alleviates this problem.

The answer I have is C, which I agree too, however it is not OA.

I think its A
Because if orthopedists can judge the stability correctly then there is no point in doing X-ray many times.
