Final answer:
Orem's Self-Care Deficit Nursing Theory is especially suited for working with homeless teens within community health nursing practice due to their unique self-care needs and barriers. Social Security and Medicare are assistance programs primarily designed for the elderly. The active participation of an older woman in community activities after retirement exemplifies Rose's subculture of aging theory.
Step-by-step explanation:
Orem's (1985) Self-Care Deficit Nursing Theory is applicable to various settings in community health nursing practice. While it can be relevant to working with populations such as families, war veterans, and politicians, this theory is especially suited for addressing the unique needs of homeless teens. Homeless youth often face significant barriers to self-care due to lack of resources, which can be addressed within the Self-Care Deficit framework. Moreover, since this theory emphasizes individualized care and self-management, it aligns well with the autonomy and varied challenges that homeless teens may encounter.
In relation to social security and Medicare, these programs are primarily designed to assist the elderly, providing critical support during retirement. Both programs are central to the economic well-being of older adults and are not primarily directed towards the poor, young families, or those in urban areas.
The situation described with an older woman retiring and engaging in community activities like swimming at the YWCA, serving on the library board, and joining a local gaming group illustrates Rose's (1962) subculture of aging theory. This theory posits that as elders disengage from their previous roles, they find new forms of community and social interaction with peers, often leading a more contented life in their later years.
