     A lesion of the nerve that supplies the tagged muscle may be manifested by which of the following patient presentations?

    • A protracted scapula

    • An inability to medially rotate the arm

    • An inability to laterally rotate the arm

    • An inability to adduct the arm

    • A winged scapula

    Correct Answer
    A. A winged scapula
    Explanation
    A winged scapula can be caused by a lesion of the nerve that supplies the tagged muscle. This is because the winged scapula refers to the abnormal protrusion or prominence of the scapula bone, which can occur when the muscles that stabilize the scapula are weakened or paralyzed due to nerve damage. Therefore, a winged scapula can be a manifestation of a nerve lesion affecting the muscles involved in scapula stabilization.
