HENNEPIN COUNTY EMS SYSTEM
MEDICAL CONTROL PHYSICIAN CERTIFICATION EXAM
The purpose of this exam is to familiarize you with paramedic treatment protocols. The test is based on the current published version of the Hennepin County EMS Advanced Life Support (ALS) Medical Protocols, ALS Protocol Appendix, and the EMS Council approved ambulance diversion policy (available online). It is recognized that medical control physicians have latitude in the treatment they order and, in practice, may deviate from the Medical Protocols within the limitations of the paramedics' training, approved drugs and equipment, and authorization to perform procedures. However, considering the Hennepin County Medical Protocols represent our EMS system's medical philosophy of prehospital care, please answer questions on this exam accordingly. This is an open book exam. Please read each question carefully and select the one best answer based on system policies and ALS protocols. Unless stated otherwise, questions refer to adult patients. Return your completed answer sheet to your medical director. ____________________________________________________________________________________ 1.
