I would pursue the LPN route over the MA route purely because of the mobility if offers. You might want to work in a clinic/facility/HHC right now that simply requires MA certification, but if you obtain your LPN license, you can work in any of the above locations, generally for more money than an MA, as well as in a hospital/surgical center, etc. Also, if your life changes and you decide you want to later become an RN, there are numerous transition courses ("LPN to RN" programs) available. I don't think it takes that much more time and money to obtain the LPN license versus the MA certificate.
FWIW, I'm an RN. I've worked all around the country (travel nurse, etc.), and LPN utilization varies widely. The one constant thing that I have seen - others' MMV - is that (1) LPNs aren't going away or being phased out (2) LPNs have, if anything, greater autonomy and placement that I saw 15 years ago when I started, and (3) We could talk for hours about the nursing shortage, etc., and yes, I know hospitals aren't hiring right now, etc., etc., since the economy has failed us all over the past few years: nurses who were supposed to retire, didn't, and hospitals are using less staff to do the same work and so aren't hiring any new staff.....however, eventually, someday: people are going to retire and there will be a true shortage of nurses. Ask any nurse who's been in the game more than 10 years: the "shortages" are cyclical. I remember the days of negotiating moving expenses and sign-on bonuses, retention bonuses....you name it. :) Now, I can't _get_ my local hospital to hire me. ;) I'm currently working in an allied health position on weekends...not as an RN, shall we say. ((shrug)) It's cyclical. I know that when my kids are bigger and I can work more than I can right now, I'm going to be more "employable".
Just my .02. :) Good luck with whatever you decide!!
