The short answer is to do everything by the book.
As one of the newer nurses on the staff, there is a possibility that they will want to watch you do part of your med pass. Just remember your "5 rights" of med administration, remember to wash / gel your hands frequently, and stay with the patient while they take their meds. ( Even if Mrs. Smith is alert and oriented x3, and usually takes her meds without supervision, if the state folks are there, do it by the book and stay with her till the last pill goes down.
Remember to properly disinfect your glucometer after each use, and dispose of the lancet and the test strip in the sharps container.
If they want to watch you do a dressing change, remember to change gloves and wash your hands between taking the old dressing off, and putting the new one on. (Even if it's not a sterile dressing)
If they ask you any questions, and you don't know the answer, DON'T FAKE IT! Simply say, "I don't know, but will find out and report back to you" Most surveyors will know that you're a new nurse and will give you kudos for going to find out the right answer rather than pull one out of ... well, you know....
Be consious of what the STNAs on your unit are doing. If you notice call lights on, or things needing picked up, HELP THEM! They are just as concerned as you are about doing a good job! (If there is ever a time for team work in a LTC, this is it!)
State survey is really no big deal for a floor nurse. In fact, it will be fun to watch your nurse managers running around like chickens with their heads on fire for a week. (I know, because I'm a nurse manager. We always finish the week a few pounds lighter and a whole lot more tired than we are at the end of most other weeks!)
Stay calm, stay cool, and do the great job you normally do, and you will be fine!
