Emergency room nurse Sheila DeRiso stood at the front of the high school  auditorium and looked out on her audience of 50 teenagers and parents. From a  black nylon bag she pulled out a long, plastic tube, then a stomach pump, a  speculum, a catheter and an adult diaper. The group tittered. All these items  are used in the ER every day to treat binge-drinking teens, she told them. 
Then she yanked out a white body bag and unfolded it: "And this is if you  don't make it." 
The audience was dead silent.
