This year’s Nephron Challenge (aka Nephrology Jeopardy) was moderated by Dr. James Simon from the Cleveland Clinic. 3 teams of 4 fellows competed against each other with standard “Jeopardy” style rules, with points awarded for correct responses and points deducted for incorrect responses. This year’s winning fellow team hailed from University of Arkansas. Congratulations to them and all the participants this year!

Here are a few sample questions from the session. Test your knowledge recall, and jump to the bottom to see the answers.
