I'm going to throw in my

about this issue. I'm close to finishing LPN school (end of August). I was a medical office assistant for 12 years. This is a different position than an MA in the USA as my job was mainly administrative.
I did however have one job where I was a clinical assistant to a dermatology practice. I set up equip/instruments for biopsies, assisted during biopsies, processed all specimens to go to the lab, drew up cortisone injections (including diluting cortisone in saline before drawing it up), did patient teaching on the drug Accutane and the ABCD's of moles. I also removed simple sutures (I refused to touch post-MOH's surgery sutures on the face).
Should I have been doing patient teaching on Accutane and moles? Um NO!!!! I in fact felt so uncomfortable with that duty of the job, it's one of the reasons I left. Should I have been drawing up the cortisone injections? NOPE!!! I know all of this now, but did not realize at the time just how much I didn't know. Should I have been removing sutures? (and this was without the doctor in the room, or even seeing the wound first). Probably not. I didn't know a thing about assessing for REEDA. Although, if I was ever uncertain about whether the sutures should come out at that time, I always checked with the doctor first.
Anyways, my point is, if a job is advertising LPN/LVN/MA, I take that to mean that an LPN can do the same job as an MA, but if a job is advertised strictly for an LPN, an MA is NOT qualified to do that job.
As an LPN, could I go back and do that exact same job? Sure I could. But I wouldn't as I wouldn't be using even 5% of the clinical and assessment skills I now have. Could an MA walk into the acute care nursing job that I will be doing come August 22nd? No way.
Again, I have high respect for the MA's who know their limitations as well as strengths and do their job well. Same goes for CNA's and long term care aids. The health care system needs all members of a team to work together!!!
