Hey! Anybody have good recommendations for CPN exam review books? I'm working as a school nurse right now and can't utilize hospital review courses. I'd love a good peds review book to brush up on the subject both for the test, but also for my own professional development. It's been a few years since I worked acute care! Bonus for any resources that don't cost a whole $80 (though I'll cough it up if I must). Thanks so much.
