Asking another, more experienced professional for their input is a good and wise idea, and often good clinical practice. We work as teams, and we gather information from those around us who hvae had experiences that can be learned from. You don't work in a vacuum for good reason. But when you, or anyone, nurses included, are signing their name to an order, you do it ONLY because YOU believe it is the right thing to do, regardless of who had the better idea, or who made a suggestion. If you choose to take input from a nurse or a PA, which could very well be the right thing to do in many circumstances - that is one thing. Claiming that you did it because "they said so" is pretty lame, and I hope you have better clinical judgement that to actually believe that anything you sign your name to is done because you have decided that this is the right plan, not only because someone else told you to.
Often times things that make these people believe will make them look "weak" are the very things that make great practitioners grateful and nlike their jobs even more, and make them look strong. Anyone who is hung up on being made to look "weak" by admitting a nurse or a PA gave a better suggestion than the one they had is a sure fool, and is either very scared and afraid to ask for help (we all need help) or very insecure and will eventually maker enough mistakes that they will end up without a license someday.
Funny, then, if you get razzed for a poor decision it is suddenly the PA's fault, but if it is a great plan and you receive compliments, it is suddenly all your doing. Giving someone credit for a good judgment and making an excellent suggestion that you incorporate is not poor practice nor should you be "razzed" for taking suggestions from nurses or PA's, as long as you are aware that you are the one who makes the final decision if you are signing your name - always be grateful and give credit where credit is due. This is only difficult for the immature, inexperienced, arrogant and ego-inflated/hence insecure types.
Anyone who sends an intern out into the wild wild world telling them they are prepared to "be a doctor" is creating a serious problem for some poor kid who becomes then afraid to appear clueless - which is exactly what they are - clueless. And it is OK. You are clueless, and everyone knows it, and most of the PA's and nurses want to help as long as you don't start throwing attitude around and get some real live asking-for-help-humility. Then, you are on your own baby. And expect some middle of the night calls for a 3.9 K when you get all pissed off before it is explained to you how quickly it is down trending - cause that is probably why you got the call, but you are too inexperienced to know that yet. Instead, it is easier to puff yourself up by saying how stupid that nurse was for calling. I mean 3.9 is almost 4.0 isn't it. Not for long.
