This unit is designed to examine mental health concepts introduced in the Nursing and Behavioural Sciences. The focus will be directed towards the exploration of issues arising out of adaptive versus maladaptive responses in relation to psychological, social, biological and environmental stressors. Mental health nursing care issues will be related to the hospital and community settings. The nursing theorists to be explored in this unit will include King, Orem and Peplau. Mental health nursing care and the nurse's role in relationship to the psychological, chemical and physical treatment modalities used in the mental health settings will also be reviewed. Material from this unit will enable the nurse to utilise knowledge to function at a beginning level as an holistic practitioner.
