 On a day when clinical practice is scheduled, according to the 2014-2015 academic year, the students will report to the simulation laboratory. All students in both study arms will participate in a simulated scenario, with cases validated by the National League for Nursing, in a setting that mimics an emergency department with a critical patient HPS in a state of shock. Three nursing students and a medical student will intervene in each scenario. If the scenario requires an additional intervention to guide the students or redirect situations that reach an impasse, a professor will be prepared to take on the role of an emergency room physician or nursing supervisor.
