The nurse is providing patient education for a man who has been diagnosed with a rotator cuff injury. When explaining the structures involved in his injury, what should the nurse include?

A) Nucleus pulposus
B) Medial epicondyle
C) Glenohumeral joint
D) Articular processes

A rotator cuff injury involves the glenohumeral joint, which is enclosed by a group of four powerful muscles and tendons that support and stabilize it. The other options are not in or near the rotator cuff or shoulder. The nucleus pulposus is located in the center of each intervertebral disk. The articular processes are projections in each vertebral disk that lock onto the next vertebra, thereby stabilizing the spinal column. The medial epicondyle is located at the elbow.
