Study Notes

Aging and Its Effects

Intrinsic aging: Refers to the natural biological processes of aging that are genetically determined, like skin elasticity loss.
Sum of intrinsic and extrinsic aging: Known as biological aging.
Psychosocial issues not associated with aging: Examples might include unrelated mental health disorders that don't correlate with aging.
Evaluating age-related changes: Consider functional status, medical conditions, and individual lifestyle factors.
Attributing findings to age: Avoid assuming all changes are due solely to aging without considering health conditions or medications.

Auditory Changes

Common auditory change with aging: Presbycusis, a gradual hearing loss often affecting high frequencies.
Regular evaluation for auditory changes: Hearing assessments should be conducted periodically as part of health check-ups.
Hearing difficulties in noise: Older adults may struggle to hear due to impaired sound processing abilities.
Inability to hear certain sounds: Known as auditory processing disorder.
Ear canal changes: Tendency to become thicker and drier, contributing to hearing challenges.

Physiological Changes in Aging

Increased arterial stiffness: Results in elevated blood pressure and can affect cardiovascular health.
PaCO2 and PaO2 changes with aging: True; aging is often associated with increased PaCO2 and decreased PaO2.

Nutritional Risks and Management

Indicators of nutritional risks in elderly patients: Include unexplained weight loss, changes in appetite, and difficulty chewing or swallowing.
Management for skin changes: Regular moisturizing routines can help combat dryness and skin fragility.

Respiratory and Renal Changes

Respiratory changes in elderly patients: Decreased lung capacity and reduced cough reflex increase infection risk.
Renal changes related to aging: Reduced glomerular filtration rate (GFR) impacting kidney function.

Gastrointestinal and Musculoskeletal Management

Management strategy for gastrointestinal changes: Increase dietary fiber intake to prevent constipation.
Musculoskeletal changes findings: Loss of muscle mass and strength, known as sarcopenia.
Management for musculoskeletal issues: Physical therapy and regular exercise to maintain strength and mobility.

Cardiovascular and Endocrine Changes

Cardiovascular changes findings: Higher risk of heart disease due to arterial stiffness and other factors.
Common endocrine changes in older adults: Include altered glucose metabolism leading to higher diabetes risk.
Management strategy for endocrine changes: Regular monitoring and adjustment of medications.

Immune System and Infection

Immune function affected in older adults: Reduced immune response increases susceptibility to infections.
Common infection areas in older adults: Urinary tract, respiratory infections, and skin infections.

Cognitive and Mental Health

Tool for assessing cognitive changes: Mini-Mental State Examination (MMSE) or similar cognitive assessments are commonly used.
Reversible causes of dementia/delirium in ICU: Include metabolic imbalances or infections that can be treated.

Mental Health and Medication Use

Leading cause of suicide in elderly individuals: Often attributed to untreated depression or lack of social connections.
Percentage of older adults affected by abuse: Approximately 10% of older adults in the United States experience some form of abuse.
Common challenge in medication use: Polypharmacy, which increases the risk of adverse effects and interactions.
Medication dosing rule of thumb: Start low and go slow, especially when adjusting dosages for older adults.
