"He keeps scratching the aching leg, sir.” There was a long silence, “Doctor?...”
“Erm, yes, yes, of course, tell him to stop.”
“I already did, but he won’t stop, and the rash is getting worse.”
“Which patient?”
“511”
“Fifth floor?”
“Yes”
“Load him then.”
“All right Doctor.” said the nurse as she left, heading to the fifth floor.

As she arrived, she knocked on the room 511 though this was a pure formality since instantly after knocking, and without expecting an answer of any kind, she would open the door and follow the doctor’s orders. Only this didn’t happen, the door wasn’t locked, they couldn’t be locked, but this doesn’t mean you couldn’t block it, any patient with a piece of brain, could figure out that by moving the small table and positioning it in the right spot, you could avoid any door-related disturbance, at least for a while, before security showed up, and this tend to happen more than usual, specially in the fifth floor.

Of course, this nurse knew that, and almost with a trained reaction she went back a few doors until she reached the nurse’s station and paged a number she knew well.. “Security in 511” she said.
