In this fourth book of the Medical Masterclass series, Acute medicine, we cover most of the situations that you are likely to encounter in the emergency department or the medical assessment unit. It encompasses the acute core competencies that are expected of doctors in their first few years of training. The key points are emphasised, and this book also includes self-assessment questions (SAQs) in the style of the MRCP(UK) Part 1 and Part 2 exams.
