Commuter and others are "right" in that it's the nature of the beast in any profession.
However, I'll play devil's advocate here, just for fun.
The healthcare "team" has many players. If we take an analogy such as a sports team, lets look at what happens when one player scores the winning goal: the rest of the team bum-rushes that player, lifts him or her up on their shoulders and parades them around. It doesn't matter if that teammate was the lowest ranking or the highest, he or she is going to be recognized. And if a teammate made a crucial assist in getting the ball to the right guy to score, well that teammate gets back-slaps as well.
These kudos are part of what bonds a winning team together in pursuit of a common interest.
I'm not saying we can make a direct analogy when it comes to the healthcare "team", but I think we'd all be better served to practice "congratulating" each other when appropriate. This "nurse as unsung hero" scripting has for so long been accepted and promoted within our ranks, that its been firmly grafted in as a core cultural norm and value. In threads like this, that norm is continually reaffirmed and indoctrinated.
Of course I agree that "helping the patient" is all that really matters, but helping the patient is that proverbial football kicked through the uprights. Score!
Maybe the intern in the OP's example technically kicked the ball, but without the OP holding the ball for him, well...you get the picture.
We nurses can start with ourselves. We can congratulate eachother, and (gasp) congratulate the physicians we work alongside.
Somewhere along the line I started making a point to commend physicians --when I noticed good catches, or excellent practice, or excellent patient care--it makes a difference. It makes a difference in how they view "the nurse" as well, I think. There have been times I've actually stopped docs in the hall to convey my respect, gratitude, and admiration for some point of excellence I've taken note of.
It changes the nature of the relationship.
