You walk in to the previous shift mess to take care of. Wet patients that haven't been toileted since the first part of the previous person shift. Gather items for your shift to set-up, give water, get through the meals and patients ready for bed. 45-minutes before your shift end, you are force. On your monthly schedule you probably have 4 or 5 already scheduled forces, and now you are about to get scheduled to work another shift that you didn't mentally prepare for because you wasn't expecting to work overtime.
