if you don't know, ask...ask when you have time...my first time on a truck out of EMT school in my FTO, I told my FTO (a medic) that while I had just learned what a saline lock was the day prior, I had no idea what to do with it...he proceeded to set one up and show me...then he showed me how to spike a bag. I've taken stretchers off the trucks to make sure I knew how to operate them properly...I've asked my partners to show me how to draw up meds, if they want me too.
I usually preface working with a new medic with two things right off the bat...
A. I'm a new EMT, and I'm still learning what I need to do.
B. If we catch a cardiac arrest, what do you expect of me.
Telling them right off the bat that I'm new, I let them know I'm not trying to hide anything, or pretend to be something I'm not. Plus it tends to allow them ahead of time to adjust their mentality so if they do have a teaching mode, they tend to switch to that, vs just going in like they might with a more experienced partner.
Asking them what they expect of me during a cardiac arrest for me is important, especially working with different partners. Some prefer me on the computer, time stamping meds and treatments...others want a name/DOB and help them...and i I'm helping them, some want me to hand meds, others want me handing them supplies and equipment...everyone is different, and if you can figure out what they want done when and how, they will appreciate it, and you'll have an idea ahead of time, and won't be fumbling around like an idiot with no idea what to do.
