LRA 218 Final Exam Questions and
Answers6
Frozen Shoulder - ANSWERS-What is the common term for idiopathic chronic adhesive
capsulitis?
Internal Rotation - ANSWERS-Which of the following AP shoulder projections demonstrates the
lesser tubercle in profile medially?
True - ANSWERS-For AC joint weight-bearing studies, patients should not be asked to hold on to
the weights with their hands; rather, the weights should be attached to the wrist.
False - ANSWERS-A posterior dislocation of the shoulder occurs more frequently than an
anterior dislocation.
True (2) - ANSWERS-Sonography is an effective diagnostic tool in studying the shoulder joint.
Increase the cephalic CR angle during repeat exposure - ANSWERS-A radiograph of an AP axial
projection of the clavicle demonstrates that the clavicle is within the mid-aspect of the lung
apices. What should the technologist do to correct this error?
parallel - ANSWERS-The AP humerus requires that the humeral epicondyles are ________ to the
IR.
AP and horizontal beam transthoracic lateral shoulder projection - ANSWERS-A patient enters
the department with multiple injuries including a possible fracture of the left proximal humerus.
Which positioning rotation should be performed to determine the extent of the humerus
injury?
, Internal Rotation (2) - ANSWERS-Which of the following AP shoulder projections demonstrates
the lesser tubercle in profile medially?
No positioning errors occurred - ANSWERS-A lateral elbow radiograph demonstrates about half
of the radial head superimposed by the coronoid process of the ulna. Which of the following
occurred?
Medial rotation oblique - ANSWERS-A radiograph of the elbow demonstrates the radius directly
superimposed over the ulna and the coronoid process in profile. Which projection of the elbow
has been performed?
True lateral with 90º flexion - ANSWERS-Which routine projection of the elbow will best
demonstrate an elevated or visible posterior fat pad?
Scapular Y lateral projection - ANSWERS-Which of the following projections can be performed
using a breathing technique?
