Overview• When are age-associated changes most
advanced/pronounced?• Complications?
- May alter the person’s response to illness- Show great variability among individuals- Often impacted by genetic &
long-term lifestyle- Common decline in functional
reserve with reduced response to stressors

Statement of Problem• Why are gerontological changes important in care and
assessment?- Can affect health and functionality and require
therapeutic strategies- MUST be differentiated from pathological processes- Predisposed to disease- Altered disease presentation- Responses to treatment and outcomes

Renal & Genitourinary System• A. Definition
− Determine renal function− Calculation of creatinine clearance
• B. Implications:− Decreased in kidney mass, blood flow− Reduced bladder elasticity, muscle tone, capacity− Males; prostate enlargement− Reduced renal functional reserve; risk of renal
complications in illness − Risk of volume overload, dehydration− Increased risk of urinary urgency, incontinence, UTI

Renal & Genitourinary System• C. Assessments:
- Assess renal function- Assess for fluid/electrolytes and acid- Evaluate urinary incontinence- Assess UTI symptoms

D. Care Strategies• Monitor nephrotoxic and renally cleared drug levels• Maintain fluid and electrolyte balance• For nocturnal polyuria: limit fluids in evening, avoid coffee,
prompt a voiding schedule

Oropharyngeal & Gastrointestinal Systems
• A. Definition:−Healthy BMI: 18.5-24.9; overweight: 25–29.9; obesity,
30+• B. Implications:
−Decreases in strength of muscles of mastication, taste, and thirst perception
−Decreased gastric motility and delayed emptying−Decreased metabolism of drugs
![Page 12: Age Related Changes in Health](https://reader035.fdocuments.in/reader035/viewer/2022062305/56816571550346895dd80733/html5/thumbnails/12.jpg)
Oropharyngeal & Gastrointestinal Systems
• B. Implications:− Risk of chewing impairments− Fluid imbalances; poor nutrition− Maldigestion-induced ulcers
• C. Assessments:− Assess oral cavity− Bowel sounds− Stable liver function tests− Monitor weight; calculate BMI− Constipation and fecal incontinence
![Page 13: Age Related Changes in Health](https://reader035.fdocuments.in/reader035/viewer/2022062305/56816571550346895dd80733/html5/thumbnails/13.jpg)
D. Care Strategies• Monitor drug levels and liver function tests• Assess nutritional indicators• Educate on lifestyle modifications and
OTC medications• Education on normal bowel frequency,
diet, exercise• Encourage mobility• Encourage participation in
community-based nutrition programs
