ASN with BS in Computer Science, how long for MSN-Informatics

Hi Guys. How're you all doing? Can you please tell me how one can be a Nurse Informatics (the board certified one) when you hold an RN-ASN and Bachelor's in Computer Science?? Thank You..

I am still an LPN Student with A.A.S. in Computer Science? Do you think it would be wise to choose this route: After LPN, I will do Excelsior and get my ASN then do my bachelor's in Computer Science then do MSN in Nurse Informatics? Is it possible to skip the BSN if you already have a B.S. in Computer Science? Thank You so much. I always want to plan ahead of time.

TY,
ANGEL
