Quirks of working in an ER

I was working in the ER and, as I was walking by, I noticed a precariously labelled bin from the corner of my eye.

It was inconspicuous at first, certainly something that belonged in the department.  At first glance, I passed it off as a common bin I had walked by dozens of times. Something, however, compelled me to take a second look.  That look caused a thought to pop into my head.

What if someone actually grabbed the wrong machine for the particular task that they had intended?  I mean, if you know the difference between a Breathalyzer and a Rectal Thermometer, then you know that the chances of that happening are pretty slim.  But there is that possibility that it could happen.  I do work nights and there are some shifts where we are all pretty exhausted.  There's really no way a trained professional would make that mistake.

Yet, could you imagine the results if they did?
