A mental health nurse is providing preventive care for a group of clients in the community. Which of the following actions by the nurse demonstrates a secondary prevention strategy?

A reason: Leading a group discussion with several clients who have schizophrenia and are dealing with tardive dyskinesia. This action represents tertiary prevention, as it involves managing long-term symptoms and complications of an existing condition (tardive dyskinesia) in clients with schizophrenia. B reason: Screening college students who demonstrate manifestations of depressive disorder. Screening for depressive disorders is a form of secondary prevention. It aims to identify and treat mental health conditions early before they become more severe, thus preventing further complications. C reason: Training volunteers in an adult day care facility to communicate effectively with clients who have cognitive impairments. This action is an example of tertiary prevention, focusing on improving care and support for clients with existing cognitive impairments, rather than preventing the onset or progression of the condition. D reason: Teaching personal coping skills to a group of adults whose parents have Alzheimer's disease. This action represents tertiary prevention, as it aims to help individuals cope with the stress and challenges of caregiving for relatives with Alzheimer's disease, rather than preventing the condition itself.
