I agree with everyone that posted here. I am just a beginning nursing student, starting clinicals. And to tell you the truth I don't have the fear of killing anyone either. I worked in a nursing home before and learned to separate life and death. None of the nurses that I worked with ever killed a patient. If you are careful, double check and are confident in the work you do, you have no reason to doubt your abilities. Being stressed over killing someone, does more harm than good and may even make you make a medication error. You know working, if you have any doubts about medications or treatments, to ask before you give. This is the only recourse you have. You sound confident and comfortable. I hope every nurse that ever works on or with me, to feel the same. ------------------ Best of Luck!
