Yesterday was my 2nd day on the job as a emt-advanced. I have never worked with an EMS agency prior to this. I have an FTO who will be grading my performance for 2 weeks to see if I can do the job or not. My first day I think I did terrible. I had problems loading and unloading the stretcher and transferring patients from the hospital bed to the cot, or vice versa. On my 2nd day I could unload and load the cot into the truck with no problem. But I got a heavy patient one time and as I was backing out of the ambulance getting her out it felt like the cot was stuck but my fto just told me to pull out harder, and I did and I got her out. I keep doing stupid stuff. Here's a few instances, my fto told me how many miles were driven to say over the radio and I misunderstood him and said the wrong mileage. Another instance was when we had a patient on the stretcher and he said "pull up" so I thought he was talking about lifting the cot up but he was talking about moving the patient up on the cot. He asked me once what was wrong with me. He tells me that I'm doing crazy things and that I'm not getting much better. I'm not gonna lie my first and 2nd day I was a little nervous so maybe that had something to do with it idk. I just feel like I'm screwing up and that and the end of my training they might fire me. Any advice?
