LPN at outpatient clinic job, should I stay?

I've been working for about a month now at a large outpatient facility in the family medicine/family practice dept. The people I work with are great and they all do the same job as me, but they are medical assistants. So I am basically doing a medical assistants job. There are a few things that I do within my scope of practice that they can't- like certain injections. But the jobs is surprisingly stressful, and Im not sure its the kind of stress that is helping me grow in my field. I do a lot of administrative work- faxing prior authorizations for medications to insurance companies, sending rx refill requests to doctors, checking pt messages from vmail and documenting it in the computer, and of course there is the rooming pts and taking vital signs. The job gets hectic b/c I work for two doctors and deal with many things at once. But Im not really utilizing much of the skills i worked so hard in school for. I've been debating if I should look for another job where I can get more hands on, basic bedside care kind of work. Is that a good idea to leave after just about a month of working here? Im sure it probably doenst look professional either. But I feel like with what Im doing now, I could have jsut been an MA (medical assistants) for. Any ideas?
