Emergency Medicine: PreTest Self-Assessment and Review, Third
Edition, is intended to provide medical students, as well as house
officers and physicians, with a convenient tool for assessing and improving
their knowledge of emergency medicine. The 500 questions in this book are
similar in format 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.
To simulate the time constraints imposed by the qualifying
examinations for which this book is intended as a practice guide, the
student or physician should allot about one minute for each question. After
answering all questions in a chapter, as much time as necessary should be
spent reviewing the explanations for each question at the end of the
chapter. Attention should be given to all explanations, even if the examinee
answered the question correctly. Those seeking more information on a subject
should refer to the reference materials listed or to other standard texts in
