I work midnight's and created my own "spreadsheet" on my home computer to help keep my tasks organized. I have columns for each thing I need to write down, ie: Accuchecks, O2 sats, Drsgs, bed measurements, Temps, etc (I can't remember all the columns I have.. haha!). I have lines under each column for me to write names in, that way nothing is taken home with names on it.
When I give PRN meds that I need to chart in the Kardex, or things I need to add (so and so has a red peri-area, etc), I either write it somewhere on the sheet itself or write in a sticky and put it on the sheet. That way all the things I need to chart, O2's I need to enter into the MAR, etc are in one place. I put this on a clipboard that has an inside clasp that can be closed, so everything is protected when I'm not using the sheet. At the end of my shift, after everything is recorded, I shred everything and don't have to worry about it.
If I were to go on a day or PM shift, I might change the columns to include crush, etc; and just write the names in of who is a crush.
