I carry a closeable clipboard that has a calculator on the outside clip. Inside, I have my work schedule taped to the inside cover with my computer login information written on it, scissors, hemostats, blank SBAR forms, a copy of a directory containing department extensions, a copy of the hospital's Residents (photos and pagers), extra pens, and pertinent handouts for patient education.
On the outside of the clipboard are the completed SBARS from shift report with a printed MAR stapled to each one, and a piece of plain white paper used for a cover sheet to protect patient information. On that cover sheet is my name and phone# (can't tell you how many times I've been asked for my cellphone extension and I had no clue what it was), the tech's name(s) and extension(s), and the charge nurse's name and extension (for emergency purposes). Even though I choose to print out the MAR as a visual reminder of meds due, I still write down the room numbers and times for scheduled meds that have unusual times.
Even with all of that preparation, somebody is going to call and ask for the ONE thing that I've not included in the above. It NEVER fails. There goes the deer-in-the-headlights look.
