Gerontology is the scientific study of aging, covering physical, mental, and social changes in older adults. Geriatrics focuses specifically on the medical care and treatment of diseases in old age. In Nigeria, aging is traditionally viewed with deep respect, and older adults often hold patriarchal or matriarchal roles within the extended family structure. However, urbanization and economic shifts are gradually altering these support systems, making formal and informal nursing care increasingly vital.
Aging brings progressive decline across all body systems. Bones lose density, predisposing individuals to fractures. Skin thins and loses elasticity, increasing pressure sore risks. Cognition may see slower processing speeds, though baseline intelligence remains intact unless pathology like dementia is present.
Older adults frequently manage multiple chronic conditions simultaneously, a state known as multimorbidity.
| Condition | Core Nursing Implication |
|---|---|
| Hypertension | Monitor daily blood pressure and watch for stroke signs |
| Osteoarthritis | Encourage gentle joint movement and manage pain |
| Type 2 Diabetes | Check blood glucose regularly and inspect feet daily |
| Dementia | Maintain a safe environment and use clear, calm communication |
Managing these illnesses requires shifting the healthcare goal from complete cure to maximizing functional ability and quality of life.
Evaluating an older adult requires a multi-dimensional approach that goes beyond standard medical history. Comprehensive Geriatric Assessment (CGA) evaluates medical, psychological, functional, and social domains. Nurses use tools like the Barthel Index to measure activities of daily living (ADLs) and the Mini-Mental State Examination (MMSE) for cognitive function. This holistic review helps uncover hidden vulnerabilities that single-disease diagnoses often miss.
Falls are a major threat to the health and independence of older adults, often leading to hip fractures and loss of mobility. Environmental modifications—such as removing loose rugs, improving lighting, and installing grab bars in bathrooms—significantly reduce fall risks. Nurses should encourage regular weight-bearing exercises tailored to individual capacity to maintain muscle mass and bone density, balancing safety with the preservation of personal autonomy.
Metabolic changes and altered drug processing require careful management in old age. Reduced kidney and liver function slows drug clearance, increasing toxicity risks when multiple medications are prescribed, a situation called polypharmacy. Nutritional needs also shift; older adults require nutrient-dense foods with adequate protein and calcium, despite often experiencing reduced appetite, dental issues, or financial constraints that limit food access.
In Nigeria, family members carry the primary responsibility for long-term caregiving. This role often falls on female relatives, leading to caregiver burnout and financial strain. Community health nurses play a crucial role by providing caregiver education, linking families to local NGOs or faith-based support groups, and advocating for social policies that protect the welfare of aging populations.
