omics required for competence. It is structured around realistic, complex clinical scenarios to
evaluate the candidate's ability to synthesize knowledge, prioritize interventions, and
navigate ethical dilemmas inherent in gerontological care. Both multiple-choice and
scenario-based items are integrated to rigorously test theoretical mastery and clinical
decision-making capabilities.*
Section One: Questions 1–100
1. Which of the physiological changes is considered a normal consequence of primary
aging in the cardiovascular system? A. Decrease in left ventricular wall thickness B.
Increase in maximum heart rate capacity C. Stiffening of the aorta and large arteries
D. Reduction in peripheral vascular resistance C. Stiffening of the aorta and large
arteries Explanation: Primary aging causes structural changes in collagen and
elastin within the medial layer of large elastic arteries, leading to arterial stiffness,
widened pulse pressure, and increased systolic blood pressure.
2. A 78-year-old patient presents with insidious onset of memory loss, executive
dysfunction, and stepwise neurological deterioration accompanied by focal signs.
Which neurocognitive disorder is most likely? A. Alzheimer disease B. Vascular
cognitive impairment C. Dementia with Lewy bodies D. Frontotemporal lobar
degeneration B. Vascular cognitive impairment Explanation: Vascular
cognitive impairment typically presents with a stepwise decline, executive function
deficits disproportionate to memory loss, and a history of cerebrovascular disease or
focal neurological findings.
3. Which pharmacokinetic parameter is most consistently altered in older adults due to
age-related physiological shifts in body composition? A. Absorption rate of lipid-
soluble drugs B. Volume of distribution for water-soluble drugs C. Hepatic clearance
of phase II conjugated drugs D. Renal excretion of highly protein-bound medications
B. Volume of distribution for water-soluble drugs Explanation: Aging is
associated with a decrease in total body water and lean muscle mass, leading to a
decreased volume of distribution for water-soluble drugs (such as lithium or digoxin),
which can result in higher peak plasma concentrations.
4. Which screening tool is specifically validated to assess for delirium in older
hospitalized adults? A. Mini-Mental State Examination (MMSE) B. Geriatric
Depression Scale (GDS) C. Confusion Assessment Method (CAM) D. Montreal
Cognitive Assessment (MoCA) C. Confusion Assessment Method (CAM)
Explanation: The Confusion Assessment Method (CAM) is the gold-standard clinical
, tool used to rapidly and accurately screen for delirium by evaluating acute onset,
fluctuating course, inattention, and disorganized thinking or altered level of
consciousness.
5. According to the Beers Criteria, which medication class should be generally avoided
in older adults due to the high risk of anticholinergic side effects, sedation, and
cognitive impairment? A. Selective serotonin reuptake inhibitors B. First-generation
antihistamines C. Loop diuretics D. Inhaled beta-2 agonists B. First-generation
antihistamines Explanation: First-generation antihistamines (such as
diphenhydramine) possess potent anticholinergic properties that place older adults
at high risk for confusion, dry mouth, constipation, blurred vision, urinary retention,
and falls.
6. A community-dwelling 82-year-old woman reports involuntary loss of urine
associated with a sudden, overwhelming urge to void. What is the most accurate
classification of her urinary incontinence? A. Stress urinary incontinence B. Overflow
urinary incontinence C. Functional urinary incontinence D. Urge urinary incontinence
D. Urge urinary incontinence Explanation: Urge urinary incontinence, often
associated with detrusor overactivity, is characterized by an abrupt, intense urge to
urinate followed by involuntary leakage before reaching the toilet.
7. Which age-related pharmacokinetic change is primarily responsible for the prolonged
half-life of many renally cleared medications in healthy older adults? A. Decreased
gastric pH B. Reduced glomerular filtration rate C. Increased serum albumin
concentration D. Decreased first-pass hepatic metabolism B. Reduced glomerular
filtration rate Explanation: Renal mass, renal blood flow, and the glomerular
filtration rate (GFR) progressively decline with normal aging, leading to decreased
clearance and prolonged elimination half-lives for drugs cleared primarily through
the kidneys.
8. Which vitamin deficiency is most commonly linked to peripheral neuropathy,
macrocytic anemia, and subacute combined degeneration of the spinal cord in
geriatric patients? A. Vitamin D B. Vitamin C C. Vitamin B12 D. Vitamin K C.
Vitamin B12 Explanation: Vitamin B12 deficiency in older adults, frequently
caused by atrophic gastritis and decreased intrinsic factor production, leads to
hematological and neurological manifestations including macrocytic anemia and
subacute combined degeneration.
9. What is the primary pathophysiological mechanism underlying age-related macular
degeneration (AMD)? A. Demyelination of the optic nerve head B. Degeneration of
retinal pigment epithelium and drusen formation C. Increased intraocular pressure
causing trabecular meshwork blockage D. Opacification of the crystalline lens protein
structure B. Degeneration of retinal pigment epithelium and drusen formation
, Explanation: Age-related macular degeneration involves the accumulation of
extracellular deposits called drusen beneath the retinal pigment epithelium, leading
to progressive dysfunction and loss of photoreceptors in the central macula.
10. Which intervention is the single most effective strategy for preventing pressure
injuries in bedridden older adults? A. Frequent repositioning every two hours B.
Application of high-potency topical barrier creams C. Administration of prophylactic
systemic antibiotics D. Maintaining continuous high-flow oxygen therapy A.
Frequent repositioning every two hours Explanation: Relieving mechanical
pressure through regular repositioning (at least every two hours in bed and every
hour in a chair) minimizes prolonged capillary ischemia over bony prominences,
preventing tissue breakdown.
11. Which diagnostic modality is considered the gold standard for confirming a diagnosis
of osteoporosis and assessing fracture risk? A. Quantitative computed tomography
(QCT) B. Dual-energy X-ray absorptiometry (DEXA) C. Standard plain radiography of
the spine and hips D. Serum bone-specific alkaline phosphatase assay B. Dual-
energy X-ray absorptiometry (DEXA) Explanation: Dual-energy X-ray
absorptiometry (DEXA) measurement of bone mineral density at the lumbar spine
and hip is the clinical gold standard for diagnosing osteoporosis and monitoring
therapeutic response.
12. An 85-year-old man presents with progressive hearing loss that is worse for high-
frequency sounds, accompanied by bilateral symmetrical sensorineural deficit. What
is this condition called? A. Otosclerosis B. Presbycusis C. Meniere disease D.
Cholesteatoma B. Presbycusis Explanation: Presbycusis is the age-related,
progressive, bilateral symmetric sensorineural hearing loss resulting from
degeneration of the cochlear hair cells and stria vascularis, typically affecting high-
frequency perception first.
13. Which physiological parameter changes during normal aging regarding the
respiratory system? A. Increase in total lung capacity B. Increase in residual volume C.
Increase in forced expiratory volume in one second (FEV1) D. Increase in chest wall
compliance B. Increase in residual volume Explanation: Normal aging leads to
decreased chest wall compliance, weakened respiratory muscles, and loss of elastic
recoil, which causes air trapping and an increase in residual volume while vital
capacity and FEV1 decline.
14. What is the key clinical distinction between delirium and dementia? A. Delirium has a
slow, insidious onset with stable course. B. Dementia features acute onset with
prominent disturbances in level of consciousness. C. Delirium is characterized by
acute onset, fluctuating course, and core disturbances in attention. D. Dementia
presents primarily with isolated visual hallucinations and preserved orientation.
, C. Delirium is characterized by acute onset, fluctuating course, and core disturbances
in attention. Explanation: Delirium is an acute confusional state marked by
abrupt onset, fluctuating symptoms throughout the day, and prominent impairment
of attention and awareness, whereas dementia has a gradual, progressive onset with
relatively intact core attention until late stages.
15. Which legal document allows a competent individual to designate another person to
make healthcare decisions in the event of future incapacity? A. Living will B. Durable
power of attorney for healthcare C. Do-not-resuscitate order D. General financial
power of attorney B. Durable power of attorney for healthcare Explanation: A
durable power of attorney for healthcare (healthcare proxy) designates a surrogate
decision-maker to speak on behalf of the patient if they lose the cognitive capacity to
make or communicate medical decisions.
16. Which skin condition commonly found in older adults presents as sharply
demarcated, brown, velvety, "stuck-on" papules or plaques? A. Actinic keratosis B.
Basal cell carcinoma C. Seborrheic keratosis D. Squamous cell carcinoma C.
Seborrheic keratosis Explanation: Seborrheic keratoses are extremely common,
benign epidermal neoplasms in older adults that appear as waxy, stuck-on lesions
with varied pigmentation ranging from light tan to black.
17. Which non-pharmacological approach is recommended as the first-line intervention
for behavioral and psychological symptoms of dementia (BPSD)? A. Immediate
initiation of low-dose atypical antipsychotics B. Physical restraints to prevent
wandering and agitation C. Environmental modification and behavioral redirection D.
Complete social isolation to reduce sensory overload C. Environmental
modification and behavioral redirection Explanation: Non-pharmacological
strategies—such as identifying unmet needs, modifying the environment, simplifying
tasks, and redirecting behavior—are safe and effective first-line interventions for
managing BPSD.
18. What is the primary mechanism of action of cholinesterase inhibitors (such as
donepezil) in treating Alzheimer disease? A. Antagonizing N-methyl-D-aspartate
receptors to reduce glutamate excitotoxicity B. Inhibiting acetylcholinesterase to
increase synaptic acetylcholine availability C. Stimulating dopamine receptors in the
nigrostriatal pathway D. Decreasing beta-amyloid plaque formation via monoclonal
antibody binding B. Inhibiting acetylcholinesterase to increase synaptic
acetylcholine availability Explanation: Cholinesterase inhibitors block the enzyme
acetylcholinesterase, thereby reducing the breakdown of acetylcholine in synaptic
clefts and temporarily compensating for cholinergic neuronal loss in Alzheimer
disease.
