At the hospital where I do most of my volunteering, the cheif resident of EM told me about an incident that occured just one week before I began to serve there. It was Memorial Day weekend(Las Vegas), and a rather large man was being evaluated by one of the residents. Well, it turns out that he was very high on PCP, and decided that he didn't like the resident examining him very much. After all was said and done, 2 residents, 1 nures, and 1 gaurd were addmitted that night! Scary stuff!
