You walk into a class with a group of anywhere from 7-12 students (depending on the school). They hand you a case (here's an overly simplified one)
ex. a 25 y.o female walks into the ER with pain in the upper right quadrant of her abdomen. She has rebound tenderness..yada yada...
Her temperature is 102 degrees, her blood pressure is 140/90
she is sweating profusely, and her pulse is 24bpm.
A blood test reveals elevated white blood cells, etc.
---
You do some research and discuss the case.
