"Psychiatric Nursing is a unique tool for understanding mental health-mental illness and assisting the nurse in providing meaningful care to the client with a psychiatric disorder. The text lays a foundation with coverage of adaptation and human responses across the lifespan, with an extensive discussion of how stressors impact the mental health-mental illness continuum. In addition, it integrates neurobiological, psychosocial, cultural, and spiritual concepts and principles that give rise to various disorders. The text's lifespan approach is consistent with the concept of mental illness as a developing process, and the style emphasizes holistic nursing care. Therapeutic interventions and modalities are discussed in the context of variegated treatment options -such as family, group, psychopharmacological, and complementary therapies. The role of the nurse in diverse clinical settings is also explored, including hospital-based; medical-surgical; home health; and community.
