Question

Difficulty: MediumAging Process

A nurse is conducting a comprehensive admission assessment on a 75-year-old client being admitted to a rehabilitation facility following a total hip arthroplasty. Which of the documented assessment findings should the nurse recognize as expected physiological adaptations to the aging process? Select all that apply.

  1. Decreased chest wall compliance and a diminished cough reflexAnswer
  2. Increased time required for the pupils to adapt to dim lightingAnswer
  3. C
    A resting respiratory rate of 28 breaths per minute with accessory muscle use
  4. D
    Gradual loss of independence in basic activities of daily living due to memory deficits
  5. Reduced gastric motility and a decrease in the production of salivaAnswer
  6. F
    Sudden onset of urinary incontinence accompanied by malodorous urine

Answer

The expected physiological adaptations are decreased chest wall compliance with a diminished cough reflex, increased pupillary adaptation time to dim lighting, and reduced gastric motility with decreased saliva production.
Normal physiological changes of aging (senescence) involve a gradual decline in organ system reserve. Expected findings include stiffening of the chest wall, weakened respiratory muscles leading to a diminished cough reflex, delayed pupillary response to light, decreased saliva production, and slowed gastrointestinal motility. These changes occur universally in older adults absent of disease.

Step-by-Step Solution

1
Analyze the question requirements.
The nurse must distinguish between normal, expected physiological changes of aging and abnormal, acute, or pathological findings.
Identifying the baseline normal for an older adult is critical to recognize acute illnesses or deterioration.
2
Evaluate the respiratory and visual options.
Decreased chest wall compliance, a diminished cough reflex, and delayed pupillary adaptation are all well-documented, normal physiological changes of senescence.
Aging leads to calcification of costal cartilage and decreased muscle tone in both the respiratory and optical systems.
3
Evaluate the gastrointestinal option.
Reduced gastric motility and decreased saliva production are expected physiological age-related changes.
Atrophy of mucosal linings and decreased glandular secretions naturally occur as humans age.
4
Evaluate the remaining options for pathology.
Tachypnea with accessory muscle use, memory deficits impairing ADLs, and sudden urinary incontinence are identified as abnormal findings.
These findings point to acute respiratory distress, dementia, and urinary tract infections, respectively, requiring medical intervention.

Key Concept

Differentiating normal physiological changes of aging from pathological disease processes is essential for accurate assessment and avoiding the dismissal of acute conditions.
