X-rays & fear

by chidcguy » Wed Jun 11, 2008 2:21 pm
To allay fears whether they had misjudged the fractures even in patients with stable femur injuries, and thus do not require surgery, orthopedic surgeons often prescribe follow-up x-rays. Nevertheless, when a number of follow-up x-rays were reviewed, all the fractures that were initially screened as stable were found to have healed correctly. Thus ordering follow-up x-rays of femur fractures initially judged to be stable, is a drain on financial resources.
Which of the following, if true, most strengthens the argument?

A. X-rays of patients of several orthopedic surgeons working in numerous hospitals were reviewed.
B. General practitioners are less likely than orthopedic surgeons to judge the stability of a femur fracture correctly.
C. X-Rays of many femur injuries for which an initial x-ray is ordered, reveal no signs of any fracture of the femur.
D. Healing of femur fractures that have been surgically repaired is always assessed by means of a follow-up x-ray.
E. Orthopedic surgeons routinely order follow-up x-rays for fractures of bone other than femur bones.

A - Tells us that the sample size of the survey was large. (keep it)
B - question doesnt talk abouot General Practitioners (drop it)
C - This option talks about "many" femur injuries. tells us that in many cases the frature wasn't even there in the first case, but the question says "all" the injuries which are stable and do not require surgery, heels after sometime, so there is no need of follow up X-ray. C does not give any explaination for the few cases where there was initial fracture.
D - out of scope, (drop it)
E - out of scope (drop it)

IMO A.
