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?
No positioning errors occurred - (ANSWER)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 - (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?
