I'm working in CVICU and just graduated last May. I feel like a crappy nurse because there is still so much I don't know. I leave work after a shift and the next morning when I show up for my shift the next day, my preceptor/ night shift nurse ambush me with things I did wrong or issues that they noticed (i.e. forgetting to hook a heparin line, mix my antibiotic, chest tube was off of suction, a med wasn't given etc.). I'm almost off my 12 wk orientation and I still feel like I can't do anything right and don't know if I'm just being too hard on myself. Anyone else ever experience these issues when they were starting out? Words of wisdom?
