Emergency Medicine: PreTest Self-Assessment and Review, Second Edition, is intended to provide medical students, as well as house officers and physi- cians, with a convenient tool for assessing and improving their knowledge of emergency medicine. The 500 questions in this book are similar in for- mat and complexity to those included in Step 2 of the United States Medical Licensing Examination (USMLE). They may also be a useful study tool for Step 3 and clerkship examinations.
Each question in this book has a corresponding answer, a reference to a text that provides background for the answer, and a short discussion of various issues raised by the question and its answer. A listing of references for the entire book follows the last chapter. For multiple-choice questions, the one best response to each question should be selected. For matching sets, a group of questions will be preceded by a list of lettered options. For each question in the matching set, select one lettered option that is most closely associated with the question.
