I don't blame you for getting a wee bit testy over this. I would've done the same thing. Listening for and responding to alarms is EVERYONE'S responsibility, whether the alarm is coming from "your" section or not!! This is part of that "it's not my patient" attitude that frankly doesn't belong anywhere in health care, and it's time people were called on it. :angryfire
Your manager should put it to your co-workers another way: what if that alarm had been coming from the room of THEIR child? Wouldn't THEY have wanted someone---anyone
!---to go in and check on him/her? Would it have mattered to them one bit if the nurse answering the alarm was from the un-monitored unit? Of course not, and that's the way they need to think of it!
Where I work, the policy is that no matter where
an alarm or call light is coming from, we answer it. If a telemetry monitor is alarming from a room on the opposite hall, if a bed-check goes off in another nurse's section, if a patient we've never taken care of is yelling "Help!"........we check it out. "It's not my patient" doesn't fly---any nurse who dares to utter that phrase gets written up, and I think it should be the rule everywhere.
But, that's just me.
