Hi there! I might be able to shed some light from an MA point of view. I am working as a MA to get my hours. I absolutely love being an MA. I did have to get my certification for it, which took a year after I graduated, but I have found the experience incredible.
Each state has a differing scope on what an MA can do. In CA, we give injections, administer medication, vitals, ECGs, spirometry and desat studies, assist in procedures, and preform CLIA waived tests. Speciality dictates a lot of what testing and exposure you get. What I have found to be beneficial is my relationship with the physicians I work with. I primarily work with one, but cover as needed for others in my practice. In my office, they take the time to show me CT scans, PET scans, X-Rays, and invite me to see procedures/round with them if time allows. My primary physician is invested in my future and has being instrumental for support and knowledge going into the next years. Also in my office, clinical MAs will do prior auths for medications and some procedures, which exposes you to some administrative work as well and have helped me learn common ICD 10 codes and CTP codes.
I don't think you can go wrong with either choice, it's more of what you'd like and where you think you'll thrive. You want to set yourself up for success and start gaining hours ASAP.
