I am an ER nurse in a small Hospital We just started a Hospital based Ambulance service and have had to orient Emt-P's to our unit . We also made it mandatory for the nurses to orient to the ambulance (walk a mile in each others shoes) Our orientation is based upon previous experience and individual comfort level. It has been very interesting on both sides and has created a better understanding of each others job. We are very fortunate to have a Great Director that started as an EMT and worked her way up. Good luck and remember every case can be used as a learning tool.
