Try to remember that the state surveyors are there to make sure we maintain reasonable standards of care. They really are not there to put good nursing homes out to pasture. It's the bad ones their looking for. You would know it by now if your employer was providing sub standard care, so if you work for a home that you can be reasonably proud of. You should be OK.
About your questions...
I work in the state of Missouri. Regulations vary from state to state, not so much from home to home. So the 1 hour before and after is accurate(at least in my state). Please remember, all of these pointers are relevant ONLY to the state of Missouri, and the state is the best place to ask SPECIFIC questions. These pointers are in general only.
You do not have to wear gloves while handling the medication, but your bare hands should also never touch the pill. Nor must the pill lie on the counter, med cart, or other possible source of contamination. Our community uses bubble pop. In theory, on a good day, you should be able to pop the pill from the card to the pill cup without ever touching it. When state is in the building, of course it will fall, spill, or otherwise manage not to land in the cup. In which case you discard the pill and pop a fresh one. Remember to get another nurse to destroy if its a narc.
In my state, you do not have to wash your hands between every patient. A good squirt of hand sanitizer is absolutely appropriate. I believe that there is a cutoff though. You can use hand sanitizer if your hands are not visibly soiled,but if you have visibly soiled hands they MUST be washed. Also, I think you can only use the hand sanitizer so many times. The number of times escape me, but I think you have to wash your hands every 3 hand sanitizer applications or something like that. Check on that stat with your DON.
Glucometers must be cleaned between each resident use. We use a special type of wipe that the state(they have a list in MO. ) approves between pts.
Taking the med cart in the resident room is a NO-NO where I work. Instead I recommend park it at the doorway facing you. As long as you are within sight of that cart, I believe you are allowed to walk away from it without locking it. I wouldn't walk far. But from the doorway of that small room to the bedside is OK. From the top of the hall to the end of the hall to answer a call light is altogether too much distance.
Gloves are required for eyedrops. Remember to take a tissue.
I wish you all the luck, but just be the excellent nurse you are every day, and youll be fine.
