What is the difference between MSN NP and DNP

A DNP, or Doctorate, is a level of education - not licensure.

Someone can be a NP with the education level of masters (MSN) or a doctorate (DNP) there is no difference in the scope of practice, as that is dictated by the state.

A DNP is similar to a MD, in that, they are both doctoral level degree and can be referred to as "doctor." The scope of practice, however, is dictated by that state's board of nursing.

Point being: MSN-NP and DNP-NP is the same as saying ADN-RN and BSN-RN. Scope remains the same, just difference of education.

What is the difference? I know that you need at least a masters degree.

As far as autonomy, does a DNP needs to be working under an MD? because I know that NPs have to work under an MD.

Or is a DNP kind of an equivalent to an MD cause its a doctorates?

Tell me what I need to know please, and thanks!

Not necessarily. In some states, NP's can practice independently.

In nearly half the states, NPs can practice with full autonomy, without physician oversight. I think it's 22 states.
