Being in the field puts prehospital providers in a difficult spot. Once you are done with class, your learning is up to you. Even if you are an active learner, when you work by yourself in the field, there is no one there to tell you when you are doing something wrong. As others have said, be very mindful of the company you keep. Talk with people who stay on top of what is going on in the field and are willing to accept changes to procedures and protocols. Stay as far away from the people who say, "Why are we changing? We always do it this way."
