The nurse should determine that a client with rheumatoid arthritis can describe the septic arthritis physiologic process and knows how to relieve pain using pharmacologic and nonpharmacologic interventions. Prolonged immobility and limited activity may promote formation of a deep vein thrombosis and possibly subsequent pulmonary emboli. The client should also understand the importance of supporting the affected joint, weight-bearing and activity restrictions, and how to use ambulatory aids and assistive devices safely to promote recovery of normal function. The local application of heat and cold to an injured body part can provide therapeutic benefits; however, "high" heat may cause a thermal injury and further promote edema formation. The client should inform the health care provider (HCP) about pain that is not relieved by the current management plan.
