Help! I'm pretty much a new grad (4 months exp) and hired in a urgent care clinic!

Hello everyone. This is a long one, but I'd love the advise.

I'm in a complex situation where a community urgent care clinic wants to hire me but I'm worried that I won't get the experience I need and I may not be experienced enough for their demands. Plus I'm planning on starting a family soonish.

I'm BSN trained having graduated in June 2008 in Toronto, Canada. I did 4 month New Grad program where I rotated units for 1 month and was in Peds/NICU for 3 months. My pre grad was at Sick Childrens Gen Med/Infectious disease for 3 months (high acuity). So I have some experience but not alot. Since then I moved to the US, became licensed and looked for jobs. I've been off from active nursing for 10 months now.

I missed all the New Grad opportunities because of the timing of my licensure and then the timing of my August wedding. Plus its highly competative here in Atlanta and I think the fact that I'm Canadian doesn't help. So, the only job I found was this Urgent care clinic which sees anything from sprains and breaks to chest pain and dehydration in all populations. They probably do see some clients who should be at an ER and eventually are sent there. From my 3 x 2 hours of observation periods, it was very brief assessments, meds, phlebotomy, wound care, X-rays, EKGs. No lung assessements, GI assessments etc...

My question is....do I have enough experience to be thrown into this (yes there's a training period but I'm guess it will be brief)? And, will it give me enough experience to take a pregnancy leave 1 to 1 1/2 years from now. I want to raise my child with me at home and the US pregnancy leave does not allow for that so I would have to be off for a year or so and work part time after that. I want to set myself up so its not a problem to find work at that point.

I don't know if I should try to get into a New Grad program at the down town general hospital "Grady" or take this job and try to get as much experience as possible....maybe take a prn /PT possition on a med/surg floor after I have a little more experience. What do you think?
Help! I have to decide ASAP!

Thanks a million!
