Don't even know how much I paid for the book. It came as part of a book package ($585.00:bluecry1:) and was combined with my other texts. The grand-total for all of my texts was over $800. At that price, I am expecting that they would be accurate. I noticed the typos but I am not experienced enough to know if the content is off as well. I'm in NY. Maybe we are at the same school or maybe it's an easy go to for instructors when students ask certain questions, "Use your critical thinking skills." On a positive note, when I discussed this with my clinical instructor, she told me to send her any questions that I was confused on or if I found wrong answers in the appendix and she would verify them for me. So I'm feeling a bit more hopeful. Thanks for your help.
