Price Check

I'm sure that most nurses have heard the price check quip with regards to the bar code scanning guns they use in most hospitals these days to read patient information from their wrist bands. I got to thinking about what a nurse might do if one of these things malfunctioned and fried a patient. Surely having such a dangerous device in their hands would tempt them to utilize it when attending to the more difficult patients. Yes, I know, my imagination is both fertile and twisted.
