Yay! You've gotten 6 months under your belt
A few things about what you've brought up...why are you working 6 nights a week? If it's because theyMre short and you WANT to, then great. If you DON'T really want to work all of that OT, then quit doing it. No one is going to be in any big hurry to fill positions when they have someone willing to come in and cover. I can guarantee you that if the charge or supervisors have to start taking patients to fill in there will be new hires in there sooner rather than later.
Supplies: find out who stocks them (or isn't stocking them in your case). It's understandable that once in a while something won't be right at hand, but running all over God's country to find a foley or a bag of saline multiple times a shift is ridiculous...not to mention this probably plus a big part in the time management issues you discussed in your post.
Report...what's the policy as far as time allotted for report? (Our report time is from 7-7:30) I've got little-to-no patience for report time shenanigans. I just worked 12 hours, I want to go home. When I first started I had another RN trying to figure out the login for her phone...during hand-off time. Uh, no...you've got the next 12 to figure that out. I simply stated "I'm ready to give you report if you want it". I wasn't nasty or anything, I'm just not staying 15 minutes after my shift because someone else is screwing around with something that can be handled during THEIR shift.
When in report, if you don't know just say so. I have found that some people seem to get off on asking questions that either really aren't that important or they can easily answer for themselves when in the chart. Many a night I have not ambulated someone to the bathroom...are they steady on their feet? I have no idea because I simply don't know. On the flip side, I did learn a lot early on when I DIDN'T know something that I should have when asked. You do your best...some shifts are just a crap-show and you're lucky everyone is still breathing and has a heartbeat at the end of it. Other times you have the time to really dig into the chart. It is what it is.
Honesty, some times the charge is not your best resoirce when you have questions. You'll figure out who you can go to, the GREAT resources. At one time we had a charge nurse that I wouldn't trust to tell me how to put a pill in a paper cup. Guess who I never used as a resource when I had questions? I know who I can trust as far as resources, some of those people aren't even on my floor.
The aide I would have to talk to about the issue. S/he should be alerting you (as the primary nurse) first, unless you are unavailable for some reason.
If you have a deteriorating patient and your charge won't help/come, call a RR. Maybe the charge is indisposed at that moment, maybe they don't want to be bothered, who knows. BUT your responsibility is to your patient and if you can't get the help you need then call the rapid. BUT I would try to find out why the charge is reluctant to help when you call with a concern (unless you're calling 75 times a shift, every shift).
Those are just a few of my thoughts
Congrats on making it through your first 6 months!!! May your next 6 get better for you
