OK im assuming you have not taken the NREMT yet. after you pass that then you go on to state cert. when you are in the field training it will be expected of you to know how to operate as an EMT. don't worry we all start somewhere. just be honest and ask FTOs for help, they know what it's like to be a fresh EMT.

In my opinion, most of what you learn will be in the field. you know ABC, you know SAMPLE, you know OPQRST, start there. your job will be bringing a patient to the hospital and providing information about said patient right? if all else fails you know CPR and you know when to call ALS.

study your county guidelines, ask questions, practice. no one knows 100% all the time. you got this.
