I am in my last semester of nursing school at clinical yesterday I went to give a patient insulin and accidentally drew up Humalog instead of Humulin R my instructor questioned it and then I realized my mistake. I just feel like an idiot now. I had one other insulin related error my second semester of school I drew up the insulin in the wrong syringe ( a TB syringe). I just feel defeated now and am questioning if I have what it takes to be a safe RN. I work in the ED and have a job there once I graduate. I really do not want to make errors such as these as a new RN or put any patient's safety in harm. I accept full responsibility for my actions and realize medication errors happen and that is why we always double check high risk meds such as insulin. Am I complete idiot or did I just make a simple mistake.. any advice?
