Depending on where you work, I've heard it refered to as call light, or call bell. Maybe there's another one for it and wonder what you refer to it as on your job. Anyhooz, I am sure that there have been certain days, or certain patients that just crack you up with some really very odd requests following "Can I Help You?" Would love to hear some. Just got off a 12 hr and my particular floor is considered "The Rodeo" and could use some laughs.
