The Physiological Effects of Ageing (eBook, ePUB)

• Format: ePub

Produktbeschreibung

The Physiological Effects of Ageing is a comprehensive resource for all nurses working with older people, enabling them to apply their knowledge of the ageing process to their practice, and, in doing so, enhance care delivery. This book emphasizes the normal ageing changes before considering possible effects of ageing on body systems, using as its framework Roper, Logan and Tierney's activities of living. Although problems associated with ageing are identified, nursing assessment and interventions are considered which can help reduce the impact these changes have on a person's functional ability. Special Features: * Explores current theories of ageing * Makes use of reflective points and points of practice * Looks at key topics of maintaining a safe environment and communication * Discusses error theory, free radical theory and the immune theory * A highly accessible text which encourages holistic patient-centred care

Rezensionen

"In order to provide quality and effective care, it is important that we are knowledgeable about the needs of this group and this book provides a good grounding in this area." (International Journal of Orthopaedic and Trauma Nursing, 1 November 2011)

"The value of this book lies in the skilful way in which the authors have meshed normal and disordered physiology of ageing with Roper's models of living and nursing." (Nursing Older People, 1 May 2011)
