It sounds to me as if you did everything right. One personality trait most nurses.emt,etc. have is that they are slightly obsessive-compulsive. We all over analyze our actions because of our sense of responsibility. You would need to be concerned if you didn't go back over what was done and if it could be done better. That's how we learn to be better nurses. Your scope of experience will become greater each day and this stuff will be easier to deal with. As far as the Dr.- I'm sure he would have let you know if he thought something else should have been done-UNLESS- as you thought, the initial room assignment wasn't correct. Hang in there, it sounds as tho' you have all the right instincts.
