Aging Process and Gerontological Principles
Normal aging versus disease
A candidate must separate predictable age-related change from pathology. Normal changes include reduced skin elasticity and thinning, decreased lean muscle mass, slower reaction time, reduced renal and hepatic clearance, diminished thirst sensation, presbyopia and high-frequency hearing loss, and lower baseline temperature. These are expected, not automatically reportable as illness. Disease processes - delirium, new incontinence, sudden weight loss, acute confusion - are never "just aging" and always warrant reporting.
Functional and psychosocial frameworks
tUnderstand the difference between chronological age (years lived) and functional age (capacity to perform daily tasks). Know ADL (bathing, dressing, toileting, eating, transferring, continence) versus IADL (shopping, cooking, finances, medication management, transportation). Erikson's integrity-versus-despair stage frames late life as a search for meaning; disengagement and activity theories describe contrasting views of social participation. Also know that older adults are heterogeneous: two 85-year-olds may have very different capacity.
Common traps
Questions often bait you into attributing a change to aging. A new behavior, a rapid decline, or a change in baseline is a reportable finding. Another trap is assuming all older adults are cognitively impaired or hard of hearing; speak to the resident directly, not only to family. Avoid infantilizing language and "elderspeak."
Worked example
A resident who has always managed her own hygiene suddenly refuses bathing and seems withdrawn. The trap answer is "normal aging." The correct reasoning: this is a change from baseline, so assess for pain, depression, fear, or abuse and report to the nurse. Rule of thumb: if it is new, it is not normal aging - report it.
