I don't know if a foreign trained nurse can apply for H1B visa or not. As far as I know minimum requirement for H1B visa application is 4 years of study in US college/university ( traditionally a batchelor degree) or 2 year degree ( associate degree) plus 2 years of experience in or outside US that requires a two year degree.

My opinion is based on the H1B bulletin published in 2005. i don't know if they have changed the law.

I am not a lawyer.

good luck!
