I must say I was equally surprised at how relaxed and laid back this response seemed to be.....but then after reflecting on 16 years of long term care with one year of med surge hospital work under my belt....I can relate to this. I can remember my first med error, feeling like I'd killed someone, when in actuality, there was no effect. But as a new nurse, one doesn't realize that until years of experience and knowledge. After working in the field, and making more then one error.....because most of us do, and working in management and being responsible for staff discipline and seeing how many others make errors, it really is more common then one would think. Unless a patient ends up getting something they end up having anaphylaxis to.....it usually is not a major issue. Just learn from your mistake and always be willing to ask for help....No questions are stupid......And your manager should not be a manger if she can not be supportive, firm but supportive too!!!! Good Luck!
