I would confirmed that this is the right order before I will signed it and yes, you are responsible cause you signed it and cannot assume everything is right without double checking it. The Am nurse and Pm nurse should have time to communicate taken over to the next shift what has been going on in order to carry out and continue the task. Being a new nurse, need to be proactive. dont assume that you know. Have a staff meeting and brought that up to prevent from hapenning... Good luck!
