I wasn't entirely sure what that acronym meant either.First time I've ever seen it. I wouldn't have actually associated it with nurses,nuns or devout Christians maybe! :)  At work there are few of us who don't swear now and then. We don't do it within the work area though just in the tea room. I guess because I work in paediatrics it is more important to be mindful of what you say. We have kids aged day of birth to 17yrs and it is usually the kids swearing at us. Not just the head injuries either which you tend to ignore as it is inhibition talking. 

  We see many low-socioeconomic families and to them words with more than one syllable or more than four letters aren't in their vocabulary. Sometimes you have just got to try and ignore it because the bigger issues are : getting them to wash their hands,wear shoes and stick around long enough for some education about their child's condition. Parents will occasionally lose it and swear at you but it is usually out of fear rather than anything personal. When the children swear at me I tell them that it is unacceptable and unless they apologize and find their manners then privileges like TV;DVDs and video games will be withheld until they comply. Given their degree of boredom and dependency on technology they immediately give in and start behaving themselves.

I'm not that much of prude that I am deeply offended at the occasional slip of the tongue at work. I'm more offended by people who seem to have a chip on their shoulder and start swearing at me for no reason or a lame reason. I do take great offence to children swearing. I've been crossing the road and had a five year old drop the F-bomb at me just to get a reaction. The problem is parents swear so often in front of their kids in some families. The child has no concept of the definition of the words but knows that it offends other people and is thrown back and forth during the arguments parents choose to allow them to witness. It just leads to a very small vocabulary for some people. It ends up being a an adverb or pronoun to them in every sentence.

It isn't appropriate in front of patients at all and should be reserved for private areas. As far as good manners goes you can lead a horse to water... Some nurses are simply rude or dismissive to everyone patients and staff. There are two RNs in my unit who everyone would like to take aside and give a good kick in the behind for being so obnoxious. It ruins an otherwise good day at work. We work either in isolation rooms or in a four bedded room. If one of these two RNs is on with you it is guaranteed to be uncomfortable. It's nice to be able to converse with colleagues throughout the day.But it is as if you are asking for something unreasonable when you ask one the two RNs (I've referred to) to double check a medication with you. We double check all medications in paeds so checking meds can happen hourly.

I've worked in public and private hospitals;denominational and non-denominational ;city and country hospitals and I've seen no difference in between any of those workplaces when it comes to swearing. People aren't stupid and know where it is and isn't appropriate to swear. I think the bigger problem is good manners toward patients and other staff.
