This is a multi-case simulation. The initial patient will present with a STEMI. The resident will need to arrange for cardiac catheterization and provide appropriate medical treatment. The exact moment these orders are completed, a stroke activation will be called for a patient eligible for tPA. Stroke protocol needs to be followed and tPA will need to be given. As soon as tPA is pushed, the resident will be handed an EKG with signs of hyperkalemia and told that a patient with depression has checked in. The resident will need to immediately evaluate the patient with hyperkalemia and give appropriate medications or they will decline. As they are pushing the medications, a Trauma Level One will be called. The trauma will be an open book pelvic fracture with hypotension and a positive FAST. The patient will need a pelvic binder, blood products, and go immediately to the OR. At this time, the resident will need to follow up on the stroke and hyperkalemia patients before evaluating the patient presenting with depression.
