I. Fundamental Considerations in Gerontology
1. An 82-year-old woman tells you she’s been feeling more
fatigued but attributes it to “just getting old.” Which
gerontologic principle best explains why fatigue may be
multifactorial in older adults?
A. Age-related decline in mitochondrial function and
decreased aerobic capacity
B. Increased resting metabolic rate leading to higher
energy demands
C. Heightened sensitivity of baroreceptors causing
orthostatic hypotension
D. Enhanced bone marrow function resulting in
polycythemia
Correct Answer: A
Rationale: Aging is associated with mitochondrial
dysfunction, reducing ATP production and aerobic
capacity, which contributes to fatigue. B is incorrect
because metabolic rate actually decreases. C relates to
blood pressure control, not primary fatigue. D is wrong
since bone marrow activity declines with age, often
leading to anemia, not polycythemia.
2. Which statement about the heterogeneity of the aging
process is most accurate?
