Nice quick reference to have
Format: Paperback
I have the full blown one I keep in my home office, and have another position where I don’t diagnose often, but keep this guy as a quick reference. My second position is working with mostly people who aren’t MH professionals, and this is just helpful for a general overview/fast refresher

Made Med-Surg Less Overwhelming
Format: Kindle
This book broke down complicated nursing topics in a way that actually felt manageable. The practice questions and real-world examples helped me feel more confident and less anxious while studying for exams.
