1. Which of the following best describes the typical age-related change
in maximal aerobic capacity (VO2 max)?
A. No measurable change across the adult lifespan
B. A decline of approximately 5-10% per decade after age 30
C. An increase of approximately 5% per decade after age 30
D. A sharp decline only after age 80 with no prior change
B. A decline of approximately 5-10% per decade after age 30 — VO2
max declines roughly 5-10% per decade beginning in the third
decade, accelerating somewhat after age 70.
2. Sarcopenia is best defined as:
A. A congenital muscle wasting disorder
B. An acute inflammatory muscle disease of older adults
C. Age-related progressive loss of skeletal muscle mass and strength
D. Age-related loss of bone mineral density only
C. Age-related progressive loss of skeletal muscle mass and strength
— Sarcopenia is the progressive, generalized loss of skeletal muscle
mass and strength associated with aging, per EWGSOP2 consensus
criteria.
3. Which type of muscle fiber is preferentially lost with advancing age?
A. Cardiac fibers only
B. Smooth muscle fibers only
C. Type I (slow-twitch) fibers
D. Type II (fast-twitch) fibers

, GCS – Geriatric Clinical Specialist
D. Type II (fast-twitch) fibers — Type II fast-twitch fibers atrophy
and are lost preferentially, contributing to reduced power and
increased fall risk.
4. Presbycardia refers to which age-related cardiovascular change?
A. Increased resting heart rate variability
B. Complete loss of baroreceptor function
C. Decreased maximal heart rate response and increased left ventricular
stiffness
D. Accelerated conduction through the AV node
C. Decreased maximal heart rate response and increased left
ventricular stiffness — Presbycardia describes blunted chronotropic
response and increased ventricular/arterial stiffness with normal
aging.
5. Age-related decline in renal function most directly affects which
clinical consideration?
A. Gastric emptying time
B. Absorption of topical medications only
C. Hepatic first-pass metabolism exclusively
D. Drug clearance and dosing of renally excreted medications
D. Drug clearance and dosing of renally excreted medications —
Glomerular filtration rate declines with age, reducing clearance of
renally excreted drugs and increasing toxicity risk.
6. Which best describes normal age-related change in intervertebral
discs?
A. Complete ossification of all discs by age 60
B. No change in disc composition with age
C. Decreased water content and disc height leading to reduced spinal
mobility
D. Increased disc hydration and spinal flexibility
C. Decreased water content and disc height leading to reduced
spinal mobility — Discs lose water and proteoglycan content with
age, reducing height and cushioning capacity, contributing to
kyphotic posture.
7. Which change in the pulmonary system is typical with normal aging?
Page 2 of 64
, GCS – Geriatric Clinical Specialist
A. Increased chest wall compliance and decreased residual volume
B. No change in respiratory mechanics
C. Decreased chest wall compliance and increased residual volume
D. Increased vital capacity with age
C. Decreased chest wall compliance and increased residual volume
— Aging stiffens the chest wall, weakens respiratory muscles, and
increases residual volume while decreasing vital capacity.
8. Immunosenescence in older adults primarily results in:
A. Reduced immune response to vaccines and increased infection
susceptibility
B. Enhanced antibody production compared to younger adults
C. Complete loss of innate immunity
D. Increased lymphocyte proliferation rates
A. Reduced immune response to vaccines and increased infection
susceptibility — Immunosenescence blunts adaptive immune
responses, reducing vaccine efficacy and increasing infection and
cancer risk.
9. Which best characterizes age-related change in postural control
systems?
A. Increased vestibular sensitivity with age
B. Complete loss of proprioceptive function by age 65
C. No change in sensory reweighting strategies
D. Decreased reliance on vestibular input with increased dependence on
visual and somatosensory cues
D. Decreased reliance on vestibular input with increased
dependence on visual and somatosensory cues — Older adults often
shift toward greater visual and somatosensory dependence as
vestibular function declines, impairing balance in low-light or
unstable surface conditions.
10. Which best describes the typical age-related change in resting
metabolic rate?
A. A steady increase throughout adulthood
B. A rapid decline only in the ninth decade
C. No change once adulthood is reached
D. A gradual decline, largely attributable to loss of lean muscle mass
Page 3 of 64
, GCS – Geriatric Clinical Specialist
D. A gradual decline, largely attributable to loss of lean muscle mass
— Resting metabolic rate declines gradually with age, primarily due
to reduced lean muscle mass rather than fat mass changes alone.
11. According to the Fried Frailty Phenotype, which combination of
criteria is used to identify frailty?
A. Body mass index below 18.5 alone
B. Cognitive impairment, incontinence, and polypharmacy only
C. Presence of three or more chronic diseases regardless of function
D. Unintentional weight loss, exhaustion, weakness, slow gait speed, and
low physical activity
D. Unintentional weight loss, exhaustion, weakness, slow gait speed,
and low physical activity — The Fried phenotype defines frailty as
meeting 3 or more of 5 criteria: weight loss, exhaustion, weakness,
slow gait speed, and low activity; 1-2 criteria indicates pre-frailty.
12. A geriatric syndrome is best described as:
A. A condition exclusive to nursing home residents
B. A genetic disorder appearing only in advanced age
C. A single-organ disease with a clear etiology
D. A multifactorial health condition resulting from the accumulated
impact of impairments across multiple systems
D. A multifactorial health condition resulting from the accumulated
impact of impairments across multiple systems — Geriatric
syndromes (e.g., falls, delirium, frailty, incontinence) arise from
multiple underlying impairments interacting across organ systems
rather than one discrete cause.
13. Which of the following is classified as one of the classic 'geriatric
giants'?
A. Hyperlipidemia
B. Hypertension
C. Osteoarthritis
D. Instability (falls)
D. Instability (falls) — The classic geriatric giants are instability,
immobility, incontinence, and intellectual impairment.
14. Failure to thrive in older adults is characterized by:
