Group as many things together as you can. For example, its now a habit for me to check if my patient needs more water or another blanket or anything if I'm leaving the room for something else so that I can grab all things at once. Also, our policy is we have a 1 hour window before and after med times to give the med. So if the pt has an 1100 and a 1230 med I can give them both at 1130 and save time.
Also write down EVERYTHING, don't just assume you'll remember. That's something that I had to learn.
