This book provides a practical, accessible guide for mental health nurses confronted with emergencies so as to enable them to manage these emergencies in a therapeutic, safe and legally proper manner. As with all emergencies, the immediate care of patients with mental health problems must be simple and quick, and so this book comprises easy to read bulletted short notes with an emphasis on establishing the diagnosis while maintaining a high index of suspicion. The book is from the same team as the Oxford Handbook of Mental Health Nursing, to which it is cross-referenced.
