I was wondering about this as the nurses prepped the patient for the intubation. I felt the need to exclaim at that point to anyone who would listen, "Wow, what a great sign! If this weren't up here I was just going to come in here and fuck around, but now, wow, I'm going to be extra special careful when I paralyze this guy and stick a tube down his trachea!"
After getting thoroughly pissed off at this sign I wondered why it had pissed me off. First, it distracted me from the task at hand because I actually had to think about what it meant. Second, this is not a bee, it's a wasp or a yellow-jacket. Third, the thing is stoned, look at his eyes for crying out loud! Fourth, his legs are amputated. Why? Fifth, if this was meant to be a clever play on words the word is "bee" not "be", otherwise the whole thing just doesn't flow. Finally, some paper shuffler somewhere spent lots of time creating this 'patient care initiative' and now all us stupid nurses and doctors and techs have to 'be alert' when we could otherwise be comatose.
So the answer about what this means is that it is posted as a reminder in patient's rooms who are at risk for falling. Seems that we don't want just anyone to see a sign in plain English that states that the patient is at risk for falling for fear of offending the easily offended. Now this is gargantuanly stupid. I therefore spent a few hours thinking of how this might be improved and I came up with this sign...
THIS PATIENT IS AT RISK OF FALLING.
