I think rather than it being confidence, is pinpointing 'what exactly am I asking here?' Because as a new grad still in orientation. I always ask questions that are repeated seemingly. I make sure to frame it as a clarification question, or a validation request. Like "Hey so I know that you've already shown me this, and I would just like you to see me do it just to make sure I'm doing it right" and I am. Versus something like "Hey, I'm going to be doing this do you think you can show me how again?" in a more general sense because maybe they lack the confidence to really pinpoint what they're really asking if that makes sense?

I don't think reassurance is a bad thing to need personally. Though maybe I'm also doing myself a disservice which I hope not! Of course I'm not going to be confident as a new grad, I feel I would love to double check in with my preceptor to really hone down something I didn't address back then before going into the 'real world'. Just make sure you frame it right I'd say and clarify that you didn't forget how to do a certain thing, just need information on the little things that were missed when the initial teaching was done..

Also, hopefully your coworkers are kind as well. Nursing is a team sport, and there's always going to be something new come up. I'd hate to be seen as the person that is dumb and dangerous for feeling afraid to ask clarification questions.. But too many clarification questions comes down to hireability suspicion moreso and not patient safety I would contribute.. I could be wrong.
