need help , would you please clarify to me

Need help desperately!!!!!!!!!!!!!!!!!!!
I just want to get some information from you guys regarding the requirements for CRNA admission program in. I am an IMG with MD degree. Infact I graduated more than 10 years ago and since then I have been working as Gneral Medical Practitioner in my home country. I came to USA two years ago. I have been studying for residency application here in the States.However, I wanted to switch to RN and then to CRNA as I would love to work in the OR,but I found it dificult to achieve that either as Anaesthesiologist or Surgeon through USMLE results. Hence I chose to RN to CRNA program.

My qestion is,in the prerequesites to CRNA; BSN or equivalent, high GPA and the GRE OR TOEFL. so,1) is there anyway that My MD degree that I got back in my home country be considered as BSN, I mean if I have my transcripts are evaluated by WES? 2) Which GPA is to be considered or taken into consideration as prerequeites; the one I had in Medical school or the one I am going to earn in RN program? Because, my GPA in medical school was not that much good to be 3 or above for CRNA program admisssion.

Thanks in advance,
Bless you!
