Query: Companion piece to the textbook.

As an emergency medicine resident, I am reading this text as part of the program. The review book is laid out in the same way as the texts. The questions are all referenced in the Howell text with appropriate discussion. The questions are overwhelmingly in the single best answer format. There is a high proportion of questions in the negative (all are true except). The questions go over the major parts of the chapter. Anyone using this text for reading will benefit from the review offered by this book.
