I can't imagine what it's like to be let go so on early on in your first RN job. I feel for you. There will be another job and you will improve! I am working in an RN Residency program (unpaid, temp & no potential for a job offer, sigh...) on a telemetry unit. I ask a ton of questions. I sometimes ask the same question of different RNs because I appreciate different nurses judgement and approach. And it helps me develop mine. And I take the time to share that that is why I ask questions. It sounds like what may have been the most concerning aspect of your error is the way in which you communicated. We have to be accountable for our actions, even as new grads, even with preceptors training us. It sounds as though you didn't give your preceptor RN an accurate, full picture of the solumedrol order change. And that wasn't fair. That put your preceptor in an unfair position, especially when you say "but I told my nurse". That's kind of passing the buck to someone else. I have moments (sometimes a lot of them in one shift) where I feel my critical thinking could have been stronger or I missed an opportunity in terms of thinking ahead/anticipating potential complications, none of us are perfect. But if I were a manager, a lack of accountability & poor communication skills would worry me. You're patients were okay. And you will be, too. Keep your head up & communicate clearly!
