Physiological Changes and Nursing Considerations

NCLEX Review Guide: Growth & Development - Care of the Older Client

Physiological Changes in Aging

Cardiovascular System Changes

  • Decreased cardiac output and increased peripheral vascular resistance lead to higher blood pressure and reduced exercise tolerance in older adults.
  • Heart valves become thicker and stiffer, potentially causing murmurs and decreased cardiac efficiency.
  • Baroreceptor sensitivity decreases, increasing risk for orthostatic hypotension and falls.

Key Points

  • Monitor for orthostatic changes: BP and pulse sitting and standing
  • Encourage gradual position changes to prevent falls
  • Assess for signs of heart failure: edema, shortness of breath, fatigue

Respiratory System Changes

  • Decreased lung elasticity and chest wall compliance result in reduced vital capacity and increased residual volume.
  • Weakened respiratory muscles and decreased cough reflex increase risk for pneumonia and aspiration.
  • Alveolar surface area decreases, leading to reduced gas exchange efficiency.

Memory Aid: "COPD Risk"

Cough reflex decreased
Oxygen exchange reduced
Pneumonia risk increased
Deep breathing exercises important

Musculoskeletal Changes

  • Bone density decreases (osteoporosis), particularly in postmenopausal women, increasing fracture risk.
  • Muscle mass and strength decline (sarcopenia), affecting mobility and balance.
  • Joint cartilage deteriorates, leading to stiffness and decreased range of motion.

Clinical Scenario

An 82-year-old female client reports difficulty getting up from chairs and frequent stumbling. Assessment reveals decreased muscle strength and bone density. Priority nursing interventions include fall prevention strategies and referral for physical therapy.

Neurological Changes

  • Brain volume decreases and neurotransmitter production declines, affecting processing speed and memory.
  • Sleep patterns change with decreased REM sleep and more frequent awakenings.
  • Sensory changes include decreased vision, hearing, taste, and smell, affecting safety and nutrition.

Key Points

  • Normal aging does NOT include dementia or severe cognitive impairment
  • Assess for depression, which is often underdiagnosed in older adults
  • Provide adequate lighting and reduce environmental noise

Nursing Considerations & Interventions

Medication Management

  • Polypharmacy risks increase with age due to multiple chronic conditions and decreased drug metabolism.
  • Kidney function declines, requiring dosage adjustments for renally excreted medications.
  • Increased sensitivity to CNS depressants increases fall risk and confusion.
  1. Review all medications including OTC and supplements
  2. Assess for drug interactions and contraindications
  3. Monitor for adverse effects and therapeutic responses
  4. Educate on proper administration and storage

Safety & Fall Prevention

  • Falls are the leading cause of injury in older adults, often resulting in hip fractures and head injuries.
  • Environmental modifications include removing throw rugs, improving lighting, and installing grab bars.
  • Regular vision and hearing assessments help identify correctable sensory deficits.

Fall Risk Factors vs. Prevention Strategies

Risk FactorsPrevention Strategies
Medication side effectsRegular medication review
Environmental hazardsHome safety assessment
Muscle weaknessExercise programs
Poor visionRegular eye exams

Commonly Confused Points

Normal Aging vs. Pathological Changes

Normal AgingPathological (Requires Intervention)
Mild forgetfulnessSevere memory loss affecting daily function
Decreased processing speedConfusion and disorientation
Some hearing lossComplete hearing loss without known cause
Occasional word-finding difficultyInability to communicate effectively

Quick Check

  • ☐ Can you differentiate between normal aging and disease processes?
  • ☐ Do you know the priority interventions for fall prevention?
  • ☐ Can you identify polypharmacy risks in older adults?

Study Tips & Memory Aids

Sleep disorders
Problems with eating/feeding
Incontinence
Confusion

Skin breakdown

Common Pitfalls

  • Don't assume confusion is normal aging - always assess for reversible causes
  • Never use age alone to determine treatment decisions
  • Avoid infantilizing older adults - maintain dignity and respect
  • Don't overlook depression symptoms that may mimic dementia

Self-Assessment Checklist

  • ☐ I understand normal physiological changes of aging
  • ☐ I can identify priority nursing interventions for older adults
  • ☐ I know how to assess for medication-related problems
  • ☐ I can implement effective fall prevention strategies
  • ☐ I understand the difference between normal aging and pathology

Remember: Every older adult is unique! Focus on individual needs, maintain dignity, and promote independence while ensuring safety. You've got this - your compassionate care makes a difference in their quality of life!
