May I add to the excellent advice you have already received? I'll probably forget a few things, but hopefully some of these will help you.
When coming on shift, here are a few things I do, many of which can be done in report. After a while, many of these steps won't be necessary, as you get to know the patients...
Check the lab books to see who is having labs done that day.
Check my B&B list, to see who may need MOM, enemas, etc. (I also write a reminder to check for results)
Note needed, outstanding & pending orders
Check the calendar for any resident appointments out of the facility.
Find out who the diabetics are, and how often they get accuchecks. (They are often the first people I go to on my med pass.)
Note how each patient takes their meds - crushed, whole, or whole in applesauce. (I prefer applesauce to pudding, as I have a few lactose intolerant patients.)
Note which patients leave the unit for meals, and time their meds & treatments accordingly. (They are also top of the list on my first med pass.)
Stock my med cart, if necessary. It never hurts to add some extra Thick-it, alcohol wipes, gloves, skin prep, and so on.
After my first med pass, I do some charting, new orders, & check the treatment book. I then start my second med pass & do my treatments.
Of course, space must be made for new orders, unexpected complications, and so on. But the basic prep at the start of the day seems to help my day go more smoothly. I hope this helps!
