LRA 218 FINAL EXAM QUESTIONS AND ANSWERS
Frozen Shoulder - (ANSWER)What is the common term for idiopathic chronic adhesive capsulitis?
Internal Rotation - (ANSWER)Which of the following AP shoulder projections demonstrates the lesser
tubercle in profile medially?
True - (ANSWER)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 - (ANSWER)A posterior dislocation of the shoulder occurs more frequently than an anterior
dislocation.
True (2) - (ANSWER)Sonography is an effective diagnostic tool in studying the shoulder joint.
Increase the cephalic CR angle during repeat exposure - (ANSWER)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 - (ANSWER)The AP humerus requires that the humeral epicondyles are ________ to the IR.
AP and horizontal beam transthoracic lateral shoulder projection - (ANSWER)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) - (ANSWER)Which of the following AP shoulder projections demonstrates the lesser
tubercle in profile medially?

radial head superimposed by the coronoid process of the ulna. Which of the following occurred?
Medial rotation oblique - (ANSWER)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?
