A nurse is caring for a patient with a new diagnosis of rheumatoid arthritis. What assessment findings will the nurse recognize as early signs of the disease? (Select all that apply.)
Explanation & Rationale
Choice A rationale Reporting pain in the finger joints is a hallmark early sign of rheumatoid arthritis, which typically presents as a symmetrical inflammatory polyarthritis. In the early stages, the small joints of the hands and feet are most frequently affected. This pain is caused by synovitis, or inflammation of the synovial membrane, which leads to joint swelling and tenderness. The symmetrical nature of the pain is a key diagnostic clue that helps differentiate rheumatoid arthritis from osteoarthritis. Choice B rationale A persistent low-grade temperature ranging from 100.1 to 100.4 degrees Fahrenheit is a common systemic manifestation of early rheumatoid arthritis. Because the disease is a systemic autoimmune inflammatory process, it often produces constitutional symptoms before significant joint destruction occurs. This low-grade fever reflects the body's inflammatory response as immune complexes circulate and trigger the release of cytokines. Monitoring for these non-specific systemic signs is crucial for early detection and intervention in RA patients. Choice C rationale The development of subcutaneous nodules over bony prominences is generally considered a later manifestation of rheumatoid arthritis rather than an early sign. These nodules are firm, non-tender masses that typically appear in patients with more advanced disease and high levels of rheumatoid factor. They indicate a more severe disease course and persistent inflammation. Because they take time to develop following chronic synovial irritation, they are not usually found during the initial presentation of the illness. Choice D rationale While an elevated erythrocyte sedimentation rate (ESR) is a marker of inflammation often seen in rheumatoid arthritis, it is a non-specific laboratory finding rather than a clinical assessment finding observed directly on the patient. The ESR measures the rate at which red blood cells settle in a tube; a normal range for adults is typically 0 to 22 mm/hr for men and 0 to 29 mm/hr for women. It supports the diagnosis but is not a physical sign. Choice E rationale Generalized fatigue and weight loss are prominent early systemic signs of rheumatoid arthritis. These symptoms occur because the inflammatory cytokines, such as tumor necrosis factor and interleukins, affect the entire body and increase the metabolic rate. Patients often experience profound exhaustion that is not relieved by rest, alongside a decreased appetite leading to weight loss. These constitutional symptoms frequently precede or accompany the onset of joint-related symptoms in the early phase of the disease.
