Review Of Related Disease (RRD) 4 Practice Exam

Lupus is a systemic autoimmune disease that can involve multiple organ systems. It commonly affects the kidneys (lupus nephritis), lungs (pleuritis or pneumonitis), joints (arthritis and arthralgias), and skin (malar or discoid rashes). It’s called a great imitator because its signs and symptoms are highly variable and can resemble many other conditions. Patients may present with joint pain, skin rashes, kidney problems, or neuropsychiatric symptoms that mimic other diseases, and the disease can wax and wane with periods of flare-up and remission. This broad, shifting presentation is what gives lupus its reputation as a great imitator. Other options are too limited (skin only) or focus on organs not typically primary targets, and they don’t capture the systemic, relapsing nature of the disease.
