MSN-NP or PA

1. PA would be the shortest route. However, your GPA may not give you a competitive edge given that these programs are not as prevalent and the number of applicants far exceed the number of slots available. Also be aware that PA programs require full time commitment as a student which practically makes it unrealistic to work while in school.

2. NP is an option. Since you have a non-nursing Bachelors, you could apply to Direct-entry NP programs. They can also be competitive depending on the specific program. Some programs encourage students to seek employment as a bedside RN after completing the undergraduate nursing portion of the program prior to starting the formal NP training.

Another option is to enter an accelerated BSN program, obtain RN licensure, work as a nurse, then apply to traditional graduate NP programs. This is a long route but taking everything into consideration is not a bad idea. You get exposed to nursing and patient care. You establish connections with healthcare professionals. And you get to figure out which field of nursing works best for your career goals as an NP.

3. CRNA is probably the longest and hardest goal to reach given your situation. You have to get your nursing degree first, get licensed as an RN, and obtain 1-2 years of experience as a Critical Care RN. You may face difficulty finding ICU positions as a new grad. You may have to get your foot in the door at the hospital and then seek ICU transfer later on. You may face competition trying to get into a CRNA program. Not that it's not attainable but this certainly requires the most time invested and determination on your part.
