Very Helpful!
Format: Paperback, Format: Paperback
I purchased a new copy of this book. The new book comes with a code that provides online access to a some lab resources and also an E-book version that is searchable and has excellent content. I attached a screenshot of a section of the e-book. Definitely worth it! Provides values and guide to interpreting tests and implications as well as associated nursing diagnoses. This book was recommended for a clinical nursing class but not required. I think it is helpful for my other classes as well (pharmacology, pathophysiology). I think if you get it you will see how useful it is. I purchased the 10th edition, which was published 2023.

Small and compact
Format: Paperback, Format: Paperback
I didn’t expect it to be small - which is better, I think. Should have read the info. Photo in comparison with the 2024 Nursing Drug Handbook I recently purchased.
