What initial test does the nurse anticipate the physician will order to rule out a fracture? A) Arthrography
B) Arthroscopy
C) X-ray

C
Feedback:
X-rays may show a larger-than-usual joint space and rule out or confirm an accompanying fracture. Arthrography demonstrates asymmetry in the joint as a result of the damaged ligaments, or arthroscopy may disclose trauma in the joint capsule. A CT scan is costly and not used as a first-line diagnostic tool in the initial stage of an ankle injury.
