facebook and texting at work

A question:
HAve you noticed an increase in your coworkers on facebook, or texting CONSTANTLY on their cell phones?
So much that when you have a pt. going bad, and in front of your coworkers ( who are on the computer, giggling and texting too) and you are asking the unit sec. to place orders for a STAT stuff while you are on the phone with the doctor....that these coworkers ignore you, only to ask you later " You had a pt going bad, why didn't you ask for help??" The same coworkers who have no obligation for teamwork, and are too busy to help you when they seem to have PLENTY of freetime to help out? What is the appropriate way to handle this? I have already mentioned several times that they are too loud at the nurses station, and suggested they are on facebook way too much. Now I am the bad guy because I reported above incident to my supervisor, and now one of the nurses is playing the "i'm-not-talking-to -you" game. I feel bad she got singled out, and yes it should have been handled better, but spending 4 hours a nite on facebook is ridiculous. And it sets an example for our new staff! Plus I am so embarrassed when pts family members come to the desk and my coworkers are watching you tube and laughing loudly. And my favorite, texting while in a pts. room. Sigh......
