Clinic Nurse job - lot of managing?

Hi,
I am undecided about taking a clinic nurse position and hoping you guys could help me! The job is in a county internal medicine clinic. There are I think 4-6 physicians and 4 MAs currently and this is the first time they are hiring an RN for the clinic. From the questions in the interview, it seemed like a lot of managing the flow of the clinic and managing the Medical Assistants versus actually doing hands-on tasks like VS, EKGs, etc. (because obviously the MA's can do that easily). Some of the questions I remember them asking me were "How would you feel disciplining an MA," "would you feel comfortable firing someone," etc.

I am just wondering if anyone here has a clinic nurse job like the one in this clinic. And if so, what exactly do you do all day? I'm sure the RN is also responsible for sharing the workload of the MA's such as triage, managing labs, calling insurances, etc. but how much of your time is spent doing managing and how much is spent doing other tasks and specifically what tasks do you do?

It doesn't sound like the clinic has nurse visits either. Also how much autonomy do you then have? I want a job where I know what I am doing without taking too many orders from physicians. If so, should I not take a clinic nurse job?
