This textbook was developed out of need. As a practicing school nurse for more than 25 years and adjunct instructor at the university level for the past 20 years, the author has witnessed firsthand the changes in today's school-age child. These changes drove the author to edit a comprehensive reference, which had to include basic information needed by every school nurse, as well as provide insight into emerging issues in childhood, society, and education to help prepare future school nurses for the challenges ahead and ensure their continuing professional growth. Each chapter includes comprehensive, updated information on the respective author's area of expertise. Objectives are clearly noted and relevant questions posed to aid in the student's evaluation. The book is organized into four parts. Part I shares the exciting history of school nursing. Part II acquaints the reader with the role of the school nurse in building healthy communities. Part III deals exclusively with issues that tend to marginalize today's student. This part explores mental health disorders, cultural diversity, substance abuse, gender identity, eating disorders, and bullying. Part IV leads us into the future of school health practice. Topics include legal aspects, school-based clinics, special education, school violence, crisis management, ethical issues/legal guidance, technology, and the ever-shifting paradigm for school health. In light of the global pandemic that has inflicted extensive pain and suffering, an additional chapter, Pandemics and Plagues, was added. It gives the reader an historical perspective of the scope of pandemics as well as specific information on coronavirus. It puts the current crisis in perspective and provides realistic strategies to deal with the reopening of schools. This is an essential read for all school personnel. This unique reference takes the reader on a journey from the humble beginnings of the school nurse profession through today's expanded role.
