Question

goodpastures syndrome is best defined as a syndrome associated with :
pulmonary hemorrhage and crescentic glomerulonephritis
gastrointestinal hemorrhage and glomerulonephritis
hepatosplenomegaly and acute renal failure
cardiomegaly and nephrotic syndrome
abdominal mass and hematuria

Explanation:

Goodpasture's syndrome is a rare autoimmune disease. Its key features are pulmonary hemorrhage (bleeding in the lungs) and crescentic glomerulonephritis (a type of kidney inflammation with crescent - shaped lesions in the glomeruli). The other options describe symptoms or conditions not associated with Goodpasture's syndrome. For example, gastrointestinal hemorrhage is not a main feature, hepatosplenomegaly, cardiomegaly, and abdominal mass are not related to this syndrome, and the combination in the other options does not match the definition of Goodpasture's syndrome.

Answer:

A. pulmonary hemorrhage and crescentic glomerulonephritis
