I'm a teacher considering a career change. I am fascinated by health care, but there are a lot of issues to think about before I make a commitment. One of the big worries that I have about nursing is the potential for making an error (such as overmedicating). I am also concerned about my discomfort with math and how this might affect my ability to perform well as a nurse. To add to all of this concern, I've read so much about the poor working conditions in hospitals under managed care, with many RNs worried that long shifts and overload have caused them--experienced nurses--to worry about thier making mistakes and losing licenses (as well as unintentionally causing harm). How do others deal with these issues?
