Emergency Medicine is becoming a highly valuable and popular branch of medicine in Australasia and many parts of the world. Australasian emergency medicine is recognised as one of the best practised in the world. Multiple Choice Questions form an essential part of many formal assessment processes, however, it is notoriously difficult to study for. MCQs may come in various formats. Whatever the format they are in, they can cover essential knowledge required to practise emergency medicine that cannot be covered in other formal assessment processes. They are valuable to clinical practice, regardless of their use in assessment, as MCQs could target clinically and practically relevant evidence-based information. Emergency Medicine MCQs contains over 700 single answer MCQs covering both adult and paediatric emergency medicine categorised into 24 chapters. The associated iPhone app contains another 180 MCQs divided into 3 test papers of 60 questions. Each question is associated with a detailed answer describing essential evidence-based knowledge in an easily understandable format. These answers are well referenced to Australasian and well known international textbooks, peer reviewed emergency medicine and other journals and highly regarded web resources. The contributors to the book are 13 emergency physicians and a consultant psychiatrist. This book and the associated iPhone app are aimed at doctors practising emergency medicine, in particular residents and registrars, generalists and hospital practitioners. Emergency registrars in formal training can use these publications to improve essential knowledge, identify gaps in their knowledge, practise MCQs as well as to improve critical thinking skills. Emergency physicians will find these publications valuable as a tool in continuing medical education.
