I am sorry that I cannot provide you with some breakthrough advice, all I can do is sympathize and relate. I have been a practicing RN for 3 years and was blessed to have obtained a position on a telemetry floor. This is a new facet of nursing that I have been exposed to as well as cardiac and neuro were not my strongest topics in school. But I wanted to advance in my career and challenge myself to do it. I am still doing my orientation and it will last for 12 weeks total.
As a new nurse on telemetry, I can relate to every emotion that you have expressed. I feel sick each time I am on my way to work because I am nervous, I feel afraid of the legal ramifications that can come to bite me if I fail to do my job or even if I didn't do something that I SHOULD have because "well you should have known." I hate that phrase. I also hate "well, it's your license." Thanks, like I didn't know that. Anywho, I don't know for myself how to get over this fear that's why I come to allnurses.com to read stories like yours, then I feel comforted.
It is true you can only do one thing at a time, you are only one person. And don't pretend to know everything. I often do feel as you do and I am worried that I will never get out of that feeling and I loathe that feeling of being scared. However, we are nurses for a reason because we were taught to assess the situation and then intervene. That being said, I have found coaching4nurses which I have inquired about to help find a coach to help me through my career and to help me clearly define my goals so that I can learn how to take care of my patients and feel that I have done the best that I could. I am proud of what I have accomplished of becoming a nurse also, and I have made peace with the fact that nursing will never get easier just more manageable if I know where my resources are and how to access them, then I can better problem solve and "troubleshoot" the situation.
If there is any consolation, I am thankful that you have decided to become a nurse and all that you do because it is not easy to give or even maintain compassionate care especially to difficult patients. New nurses, like me, will be thankful for your experiences and stories to help them get through their insecurities, doubt and other "head-noise." Thank you for sharing your thoughts. I wish you all the best, please don't give up.
