Another challenge we found was that students had problems breaking from the habit of completing head to toe assessments during the simulation, as they were used to doing in other clinical experiences. This sometimes caused them to take longer than the 30 seconds allotted during the first 5 to 10 victims, although they usually got the idea by their 15th victim. Also, although we felt that our plan to rotate the students was sufficient to keep them on track, some chaos prevailed when the 80 students tried to figure out where they were supposed to be but this is typical of any mass casualty scene initially chaos is everywhere. For 1 of our simulations. we invited local EMS who parked mergency vehicles outside, which added to the realism, and students got to report off on their last victims. Local news stations covered the story, which was exciting to all involved We have realized that there is a large gap of knowl nursing students and edge between our prelicensure seasoned first responders. It would have been more effective to incorporate their prelicensure counterparts, and we hope that collaboration will be made possible in the future. Our college has recently transitioned from a quarter to a semester system, and we look forward to reenacting the MCI simulation in a new Emergency Department Nursing elective course soon.
