I too am a new nurse and I am constantly amazed when I see seasoned nurses tip-toe around doctors. My opinion is "aren't we in this together" and doesn't our work include safe practice? With that in mind I do approach doc's and ask questions when my co-workers haven't the answers. So far everyone has been very helpful except for one doc and I attribute his hostility to his own insecurities. He is not the person I would seek advice from. Cheers and happy nursing!
