Chaotic Table of Contents, Chapters and pages in TOC are incorrect
Format: Paperback
I just opened it and the Table of Contents is "Chaos." The Chapters and pages in the Table of Contents (TOC) do not reflect the actual chapters and pages in the book. For example, TOC shows Chapter 8 in page 94. But if you turn to page 94, it is the second page of Chapter 9. Will continue to update this review when I start to read the book. For now, it is a "1" for the Table of Contents.

This study guide turns overwhelming Med Surg topics into organized, manageable lessons. It sharpens clinical thinking, builds confidence and makes exam prep far less stressful. A practical, well structured resource for nursing students who want clarity, focus and stronger test performance.
