NI credentials

my question is after a masters program in NI should I be able to sit for a NI credential like BC(board certified) or CPHIMS? or per their eligibility criteria I should acquire time as a NI nurse before obtaining those credentials? do I have it right?

If you want to be "nursing informatics" certified, then your certification would come from the ANCC. And yes, to sit for the exam, in addition to having an active RN license and other requirements, you need to also meet one of the following practice hour requirements:

• Have practiced a minimum of 2,000 hours in informatics nursing within the last 3 years.
  
• Have practiced a minimum of 1,000 hours in informatics nursing in the last 3 years and completed a minimum of 12 semester hours of academic credit in informatics courses that are part of a graduate-level informatics nursing program.
  
• Have completed a graduate program in nursing informatics containing a minimum of 200 hours of faculty-supervised practicum in informatics.
  

I am starting in January, so when I finish my MSN with 200 hours, I can sit for boards almost immediately? I am ortho certified and there is only one option-2 years and 1000 hours.

And why would you want to sit for "boards"?

To be a certified NI nurse. Just like I wanted to be certified in orthopedics as an orthopedic nurse. I should have been clearer: I am starting my MSN in Informatics. Why wouldn't I want to be board certified?
