Hi! Ive been a nurse for about a year and a half now. The first 14 months were med surg and by the end I felt very confident in my med surg skills. About 4 months ago I transferred to a cardiac stepdown unit (where we can also get pulled to the ICU and ccu). At first I was so excited to learn everything, now I absolutely hate it. I'm nervous every time I walk into work and do not feel even slightly comfortable with my cardiac skills. I feel that if any serious situation were ever to occur I am not going to know what to do. I am still having trouble identifying rhythms and to be honest if there was ever a code I don't know how to hook up the defib. I'm very good at patient care otherwise so my co workers think I'm doing great but truth is I know I'm only cut out for the routine aspects of the day and if any emergency were to arise I will freeze. Should I give this job more time, or be willing to admit this atmosphere isn't for me and move on after only 4 months? Any advice is greatly appreciated.
