The hip joint as well as the shoulder joint can move in all directions. They are ball-and-socket joints. A hinge joint can only move in one plane, such as with knee flexion and extension. A cartilaginous joint is a strong joint that is very slightly movable, such as intervertebral joints. A pivot joint is a joint in one plane that permits rotation, such as the humeroradial joint.

A relapse is when a person stops their positive behavior and, as a result, loses the positive benefits he or she had gained. Many conditions can lead to relapse: work pressures, boredom, and increased travel are only a few. Although similar, a lapse is a temporary stop in positive behavior. Had this client returned after a week or two, her exercise routine would have lapsed, but she would have likely maintained or quickly regained the positive benefits.

A client with dyspnea will have shortness of breath while resting or only with mild exertion. It is not normal, and it can be a symptom of cardiac or pulmonary disease. Orthopnea is shortness of breath that occurs when one is lying down. It is relieved by sitting upright or standing. Ischemia occurs when there is a lack of blood flow and oxygen to the heart. This causes pain in the chest or pain that has radiated to the neck or arm. Syncope is a loss of consciousness that usually occurs when the brain does not receive enough oxygen.
