First of all, "study" and know the proper way to dispense medications, remind yourself to do identification checks, necessary vitals prior to medication administration, etc. I kept this sheet on my cart in the weeks before state came, and "studied" daily.
When state shows up, I did the difficult patients first--GT's, people with eye drops, etc. As soon as I received report and counted narcotics I was on the floor and started right away with rounds, etc...get as many things out of the way so you can focus on med pass and not making any mistakes. . I saved the "easy" patients for last--the ones that were very compliant and took medications orally.
Remember to wash your hands before and after contact with patients. Do the ID checks. Check the medications against MAR, the route of administration, all the "checks" for med pass. Ask your resident if they are in pain.
If you have to practice with a coworker! Role play!
Hope this helps a little, I'm sure there's a lot I missed but that's what I can think of for now
