How do I get a good RN-BSN graduate job with US government?

Join the Air Force. Seriously. My sister did that, the benefits were great, she was delighted with the whole deal.

@georgekasheshe Where are you current located and are you a US citizen?

Yes am a US citizen and I live in Maryland, attended University of Maryland

US Department of health might be a start. Also see about applying at your local VA hospital.

The CDC might be another place to look. Atlanta based if I remember correctly.

You have to google the agencies and take civil service exams for each one. For the couny I work in, each test is $25 and you apply about 2 months prior to the test, and it takes 6 months for the results to come out, and then they start canvassing the list.
