Please don't take offense to this because it is not meant that way but your critical thinking skills ARE still lacking! You are a first semester student with no medical experience! I can say that because I, too, was a first semester student and worked as a receptionist at a diesel engine shop (I'm about to start my fourth semester now and I still work at the diesel engine shop)... However, three semesters later, now I have 10 times the confidence during clinicals. Just give yourself time, you will get there! I still have tons to learn and there are still many times when I feel inadequate but I am getting there and you will too!!! Best of luck to you!!!
