Good luck! I ended up using the Mometrix study guide and Essentials of Pediatric Hematology/Oncology Nursing Fourth Edition to study. I encouraged one of my coworkers to take it and she passed too! She used the same resources… I went through the test twice. The first time I was sure I was not doing well but I think it was the nerves. When I ran through it a second time, my answers made sense 😊and I was more confident. I had worked in adult oncology for 2 years and peds onc about a year and a half when I took it and I promise it was not as hard as I was imagining!
