Medicare Wellness Visits

I joined a healthcare organization several months ago to see walk in's and conduct video acute care visits.  Unfortunately, the patient volume is much lower than expected. To fill my time, I was asked to do Medicare Wellness visits and was told I would have nursing support. I said okay sure. Now I'm told I will have no nurse and it's up to me to room the patient, get vital signs, give immunizations, draw blood, and address any outgoing mail and send it through the postage machine.  I didn't get all of this education to do clerical work and nurse duties, and the company doesn't understand my resistance.  They say because I'm not very busy, I should agree,  Am I out of line here?
