Written by practicing nurses in acute care, High Acuity Nursing, Third Edition gives readers a basic understanding of complex patients and teaches them how to provide nursing care in different situations by using a series of real-world scenarios presented in self-paced, self-contained modules. These modules progress in difficulty and address multiple system problems that nurses frequently encounter in treating high acuity patients. Using a \'nuts and bolts\' approach, the book addresses essentials by using examples, analogies, and metaphors, focuses on concepts and principles that can be applied across practice settings and patient populations, and includes nursing diagnoses.
