Calling All Nurses for Help or Advice??:(

Is this how the nursing field in assisted living/memory care facilities are?

Let me start off by saying I'm a college student, hoping to become a nurse practitioner one day. I am twenty years old and finishing my second year in college. Right when I turned 18, I signed up for a technician school where I got my CNA, PCT, EKG and Phlebotomy certifications and completed them last July. As soon as I completed these certifications I went out to find myself a job at an Assisted Living and Memory Care facility as a CNA.

So I was a CNA at that facility for 3-4 months and got my basic knowledge of how to do things on the floor and I did a great job to where the nurse would call me in first in or the executive director of that facility to help out all the time they needed someone. I was very passionate for people. Then later on they offered me to be a medication aid and offered to give me free classes at this facility so I took it because I thought this would teach me knowledge on medication and all the rest.

Later on I realize that as a medication aid or as a "Med Tech (they call it there)", they run on them. There is no nurse there 24/7 so a med tech is responsible for anything else that happens there when the nurse isn't there or even sometimes when the nurse IS there.

Luckily, I got the hang of being a med tech and knew what to do and what not but later on the med tech leads (which there was only one in the assisted living side and in memory care) resigned and the facility was in search of new med tech leads. They considered me and my other friend. Myself to work up in the front (assisted living) and my friend to work in the back (memory care) now working in the front is a handful. Mainly because you work with management, the assisted living is a much more heavier job than memory care. But knowing this I took it because I thought it would be a great opportunity. But now I just feel tired, stressed, and overworked. Since the nurse isn't always there its the med techs duty to basically do the nurses job. Which is to do incident reports, chart for resident services, taking vitals and documenting, being responsible for putting in the new monthly MAR and checking it and copying whatever needs to be written, doing rounds with doctors on residents and telling them concerns of the residents or medications, faxing over medication, dealing with nurses who come from hospice or any other facility, if theres an emergency Im the first one they call, etc. I have to do a lot now on a daily basis but I feel like the nurse can be very rude and ignorant when asked questions. I just started this job 11 months ago and I feel like she doesnt understand that because she's been a nurse for 30+ years. When I have a question she has an attitude like "how would I not know", she makes the point that I'm new to this position way too many times towards the family members and everyone else, never sticking up for me. May I make it clear that I know if I leave this job the nurse would be screwed? I also feel like management doesn't realize how crazy a med techs job could be up front. I feel overworked, tired, pissed, underpaid and honestly want to quit when dealing with these crazy residents/family members/ and management . But I don't know if I should just suck it up or find a new job? Are all nursing jobs like this?
