Question 10 - Single Best Answer

Mrs. Nephro is a 29 year old black female who you have followed for a long time. She was born with abnormal kidneys. You remember her very first visit to your office: she presented at the age of 5 for her Kindergarten check-up and her urine lab studies were abnormal. She had 4.0 grams of protein in her urine, aka proteinuria (any value > 3.0 defines proteinuria). From which site/structure is she losing the protein?

A) proximal tubule
B) renal medulla
C) collecting duct
D) glomerulus
E) distal convoluted tubule

A) juxtaglomerular apparatus (JGA)
B) proximal tubule
C) collecting duct
D) glomerular basement membrane
E) mesangial cells
