What nursing reference books do you use

I'm looking for a good reference book to use as far as looking up diseases/conditions, nursing assessment, s/s, nursing interventions, etc...

What do you nurses recommend?
Get a good book on medications. Get an equally good book on lab values, and nursing diagnoses. There are also little booklets that are specific to "RN" (quick reference guides).Best of luck

Harvard Nursing Guide to Drugs is a great medication reference. Also the "A Nurses Survival Guide" series - I own quite a few of these.

Thanks. I already have drug book (Davis). Also i have little reference books, like RN notes. I'm looking for a big book (like those big nursing med surg textbooks) that can sit on my desk at home and will be my go to for in depth information. I dont mind if it weighs a ton and is two feet thick or if its several volumes.

NANDA-I 2012-2014, Blackwell NANDA, NOC, and NIC Linkages: Nursing diagnosis, outcomes, and interventions. Johnson, Bulechek et al., MosbyAnatomy Coloring Book, Physiology Coloring Book

I kept my med-surg textbooks, and bought several of the Incredibly Easy! books for fluids and electrolytes, EKGs, etc. I find it especially useful as a reference for things that I don't see all the time on my unit.
