Confused about job offer!?

[cmm4ever]

So I posted yesterday that I got a nursing assistant position on a telemetry/med surg. floor. I am grateful to land this job (hoping I will like it). Its just I planned on calling this pediatric office today to see if they got my resume and was hoping to set up an interview for soon (if I had to choose between the two). Like I mentioned previously, I interviewed last Wednesday at the hospital, saw this pediatric medical assistant position ad online Sunday, and then was offered the nursing assistant position yesterday. I went to school for medical assisting and graduated in December 2010. Im just hoping that if I take the nursing assistant position, it will be a good experience for me and that I will use some of my skills. I know the hospital right now is part time 7-3 rotating weekends/holidays. I just have no experience as a nursing assistant and just hope I like it. If you were me, would you still call up the pediatric office and try to get an interview asap? The hospital is sending me may 10 for a physical etc. and then may 23rd is supposed to be the orientation. On my fellow medical assistant board someone said to take the hospital job, I just am not sure what to do.
