A nurse is conducting a physical examination of the musculoskeletal system of a client who reports having joint pain. Which signs indicate there is inflammation in the joints? Select all that apply.

A. The trigeminal nerve (CN V) is primarily responsible for sensation in the face and the motor control of the muscles used for chewing. It does not have a role in balance or equilibrium, so it would not be the focus when assessing balance issues.
B. The facial nerve (CN VII) controls the muscles of facial expression and provides taste sensation to the anterior two-thirds of the tongue. While it plays a significant role in facial movement and taste, it is not involved in balance or equilibrium.
C. The olfactory nerve (CN I) is responsible for the sense of smell. It does not have any role in balance or equilibrium. Balance issues are not related to the olfactory nerve, so this is not the appropriate focus for balance assessment.
D. The vestibulocochlear nerve (CN VIII) has two major components: the cochlear nerve, which is responsible for hearing, and the vestibular nerve, which is responsible for balance and equilibrium. The vestibular component of CN VIII is crucial for maintaining balance and spatial orientation. When a client reports spontaneous loss of balance, this nerve should be the focus of additional assessment.

A. Subcutaneous nodules are lumps or masses that can occur beneath the skin, sometimes seen in conditions like rheumatoid arthritis.
B. Crepitus refers to a crackling or popping sound heard or felt during joint movement. It is often associated with osteoarthritis or other joint conditions.
C. Warmth or increased temperature over the joint area is a common sign of inflammation. It occurs because inflammation increases blood flow to the affected area.
D. Swelling, or edema, is the accumulation of fluid in the joint space or surrounding tissues. It is a clear sign of inflammation and can be due to increased fluid production or leakage from blood vessels.
E. Redness, or erythema, around the joint is a result of increased blood flow to the area due to inflammation. It is often accompanied by warmth.
F. Tenderness refers to pain or discomfort in the joint area when touched or palpated. It indicates an inflammatory process in the joint.
