Sample itemWhy are radiographs usually taken in two orthogonal views for fractures?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. A single projection can hide displacement
Fractures and displacement may be concealed by overlap in one projection, so orthogonal views provide three-dimensional appreciation of alignment.
Option by option
A. A single projection can hide displacement (correct)
Correct: two views reveal displacement in different planes.
B. Bone density needs two exposures
Density assessment is not the primary reason.
C. It doubles diagnostic certainty automatically
No test automatically guarantees certainty.
D. It prevents all repeat imaging
Repeat imaging may still be necessary.
