Hey Rushgrad2017, Sorry to hear you didn't pass. There is so much information and it is hard to figure out what study and focus on. Also, I guess they changed the test last year to make it harder, since AC-PNPs scope of practice has expanded, so don't be discouraged! I have not taken the test yet, but the director of our school suggested we use the NAPNAP guide and supplement with the Lippincott Certification Review: Pediatric Acute Care Nurse Practitioner book. I take the test in two weeks and then I will let you know how it goes. I also am studying using this website - ac-pnp. It provides some more test questions with rationale. I will keep in touch and let you know if what I used to study worked and if it was similar to the test.
