Totally Unacceptable
Format: Hardcover, Format: Hardcover
I purchased this at $129.81 for a new book this book appears to be used & it’s obviously damaged. This is not what I spend my money on. I need this book for class. This is unacceptable on so many levels.

Comprehensive book. Great study tool for students or nurses entering Maternal Child specialties.
Format: Hardcover, Format: Hardcover
Excellent read. Using for review before taking on a new role in Maternal Child Nursing. Comprehensive. Great tables, images, and key concepts and skills check questions are included for each chapter. My book spine is wearing out but I've read more than 1/3 the book and been toting around in a bag and has had heavy use for at least a month.
