Aging Health System Overview Summary & Study Notes

🧴 Skin & Integumentary Changes

Senile Lentigo: flat, dark macules often called age spots; an expected age-related change. These lesions are benign and common with aging.

Seborrheic Keratosis: wart-like macules with distinct edges; often mistaken for melanoma. Recognize distinguishing features to avoid misdiagnosis.

Xerosis: the medical term for dry skin; an expected change in the elderly. Gentle skin care and moisturization help minimize discomfort and cracking.

Senile Purpura: red or purple spots due to increased vascular fragility; caregivers must use caution when handling these patients to avoid hemorrhage. Gentle handling and monitoring reduce injury risk.

Seborrheic Dermatitis: common inflammatory skin disorder seen with aging. Manage with gentle cleansing and appropriate anti-inflammatory therapies as advised.

Carcinoma: skin cancers, especially basal cell and squamous cell carcinoma, are common skin disorders in older adults. Regular skin checks aid early detection.

💓 Cardiovascular & Hematopoietic Systems

Cardiomegaly: enlarged heart; a common cardiovascular aging change.

Orthostatic Hypotension: related to decreased baroreceptor sensitivity with aging; monitor for lightheadedness on standing.

Intermittent Claudication: pain or cramping in the legs with activity; often due to occlusive peripheral vascular disease.

Ischemic Stroke: describes a stroke caused by lack of blood flow to brain tissue; urgent evaluation and management is critical.

🧠 Nervous System & Sensory Organs

Dementia: common disorder; Alzheimer disease is the most common form.

Cataracts & Glaucoma: common eye disorders seen with aging.

Presbycusis: age-related hearing loss; decreased ability to hear high-frequency sounds.

Nystagmus: involuntary eye movement; vestibular atrophy can affect balance and eye coordination.

🦴 Musculoskeletal & Gastrointestinal Systems

Osteoporosis: common disorder where bones become weak; weight-bearing activity is emphasized to improve bone strength.

Osteopenia: precursor to osteoporosis; decreased bone calcium noted as an age-related change.

GERD, Diverticulosis, & Hiatal Hernia: common gastrointestinal disorders seen in older adults.

🧬 Endocrine System

Hypothyroidism: reduced thyroid gland function; often missed or misdiagnosed as depression because aging-related symptoms include lack of energy and cold intolerance.

🧭 Nursing Study Tips

SAFETY: Connect physiologic changes to patient safety; for example, decreased balance (vestibular atrophy) leads to a fall risk.

Snowball Effect: A single fall can lead to fracture, surgery, immobility, and life-threatening sepsis or pneumonia.
