first med pass, successful but slow

I am 3 days into orientation at my nursing home job, and today I got to pass meds to about 30 residents all by myself. I am on 7-3 and the first med pass took me until 11. I felt really stupid at times, because the regular nurses make it look like childs play. I have to triple check everything, and not knowing all the residents makes it that much harder. I did injections, breathing treatments, wound care, and fed residents too. I hope i did not bite off more than I could chew, will it get any easier, after orientation I will be on 3-11 and 11-7 as per diem.
