I'm an RN and sitting here with two of my coworkers outside the med room. We work in the state psych hospital.

We use a Pyxis for medication dispensing, it's a great big electronic chest with a finger print reader that holds all our medications.

The three of us are sitting here charting, and we hear the very distinct sound of someone shutting a Pyxis cubie and then slamming the drawer shut as we all do.

The three of us all gave each other weird looks and confirmed each of us heard that, because there is nobody in the med room. We all chuckled and just said "Well that's fucking weird", and went back to charting.

(There is only one door to enter and exit the med room, and that door is in front of the three of us. Nobody came or went.)
