This book focuses on the latest research in the field of nursing. Nursing is the protection, promotion, and optimisation of health and abilities, prevention of illness and injury, alleviation of suffering through the diagnosis and treatment of human response, and advocacy in the care of individuals, families, communities, and populations.
