I'm an ADN who's never been held back from management positions because I lack a bachelor's degree. However, I do NOT recommend becoming an MDS coordinator or RCM right out of school. If you've never worked the floor in LTC, you have no idea what is doable out there, and you'll end up demanding too much (or too little) from your charge nurses and aides, which means either alienating the staff or doing too much of the day-to-day stuff yourself. Neither of which will earn you the respect you need to have if you're going to succeed in this position!
As a charge nurse a few years ago, I dealt with two RCMs who had never worked the floor; accordingly, they thought up some of the most ridiculous things for me to do on NOC shift because they didn't think I had enough to keep myself busy. Unfortunately, it was the residents who paid the price in lost sleep: these RCMs scheduled routine Tylenol for 0200, suppositories for all at 0500, even once-daily straight caths for 0300. (Now, as an aging baby boomer, I can all too easily imagine being one of these poor little old people in a couple of decades, and if someone comes at me at five AM with a "silver bullet" I'll kick 'em in the teeth!!) But as an RCM myself, I use my floor experience on a daily basis to make judgments about how best to plan my residents' care. If a particular gentleman is not a morning person, why in the name of all that is reasonable would one wake him up at an ungodly hour to give him a suppository? And if a particular lady gets up with the chickens, why would you want to make her wait three hours for breakfast? It's all a matter of common sense, and you don't get that by sitting in a classroom or watching other nurses do all the work.
Oh, yeah, I almost forgot: the pay ain't bad either. Of course, you put in lots of extra hours (especially around survey time) and if you're salaried like I am, you don't get overtime. But there's nothing like working normal hours and getting weekends & holidays off.
