A staple in my pocket!
Format: Paperback
I’m a PA student in clinical rotations. This book helped me survive my ER rotation by guiding me with high yield information, differentials, physical exam and history to obtain. Love that it helps give insight on when to admit vs discharge in the treatment plan. Applicable across the board in family med, urgent care and other clinical settings other than ER too. I recommend this book to all students! My preceptors were very impressed in my thought processes and I have this book to thanks for that. I’ll be using this book throughout my career!

Straight to the point and everything you need
Format: Paperback
EMRA products never disappoint. I hardly leave reviews but this company makes the best resource materials out there. They have managed to distill down to the most important info needed to diagnose treat , and work up most diseases that present to the ED. I also have their quick pocket reference and I love those too. Only thing I would change is make the writing a but bigger. As one gets older it's hard to see
