Which organ-specific autoimmune disorder would the nurse associate with a client's kidney?

• A. Graves disease
• B. Addison disease
• C. Goodpasture syndrome
• D. Guillain-Barré syndrome

Answer: (C)

This question centers on organ-specific autoimmune disorders and which one is linked to the kidney. Goodpasture syndrome occurs when autoantibodies target the basement membranes of the kidneys (glomeruli) and the lungs, leading to rapidly progressive glomerulonephritis and potential pulmonary hemorrhage. In the kidney, this presents as hematuria and proteinuria with possible renal failure if not treated. The other conditions involve different organs—Graves disease affects the thyroid, Addison disease the adrenal cortex, and Guillain-Barré syndrome the peripheral nerves. Therefore, the kidney association points to Goodpasture syndrome.
