This page is dedicated to organizing various examples of standardized exam questions whose answer is acute poststreptococcal glomerulonephritis. While this may seem a odd practice, it is useful to see multiple examples of how acute poststreptococcal glomerulonephritis will be characterized on standardized exams (namely the boards and the shelf exams). This page is not meant to be used as a tradition question bank (as all of the answers will be the same), however seeing the classic “test” characterization for a disease is quite valuable.
Question # 1
About three weeks after an 11 year old girl is treated for cellulitis, she begins to pass bloody urine that contains RBC casts. Her blood pressure is elevated, and pedal edema is also present. Antistreptolysin O titer is 5000 Todd U (N < 166) and C3 concentration is decreased in the patient’s plasma. What is the most likely diagnosis?
Question # 2
A 10 year old girl is brought to the clinic because she has been passing dark urine. She also complains of fatigue, and mild abdominal pain. She had a sore throat and was also diagnosed with a upper respiratory tract infection 10 days ago that resolved on its one. Her pulse is 85/min, respirations are 18/min, and blood pressure is 145/90 mm Hg. A physical exam shows slight swelling around the eyes. Urinalysis shows light brown urine that contains RBCs and granular casts. What is the most likely reason for these findings?
Explanation: recent sore throat/URI + dark urine + RBC/granular casts in urine = acute poststreptococcal glomerulonephritis
