@spotiche5- Absolutely! Your friend is already well on her way to achieving her goals. With a bachelor's degree in nursing, she has already accomplished much of the hard work required to become a nurse practitioner.
Now your friend can go on to get a higher degree in nursing so she can eventually work as a nurse practitioner in the field she prefers. She will need to decide if she wants to work in a specialty field of medicine or in family medicine. The good thing about her situation is that she can continue to work as a registered nurse while she pursues a degree that will advance her career.
