Question 1: Which aging theory posits that accumulated cellular damage from free
radicals contributes to the aging process and age-related diseases?
A. Programmed Longevity Theory
B. Endocrine Theory
C. Free Radical Theory
D. Immunological Theory
CORRECT ANSWER: C. Free Radical Theory
Rationale: The Free Radical Theory of aging, proposed by Denham Harman, suggests
that oxidative damage from reactive oxygen species (free radicals) accumulates over
time, damaging cellular components like DNA, proteins, and lipids, thereby contributing
to aging and age-related pathologies. This theory underpins much of the research on
antioxidants in gerontological care.
Question 2: When conducting a comprehensive geriatric assessment, which
domain is considered foundational for determining an older adult's ability to live
independently?
A. Cognitive status
B. Functional status (ADLs and IADLs)
C. Social support network
D. Medication reconciliation
CORRECT ANSWER: B. Functional status (ADLs and IADLs)
Rationale: Functional status, encompassing Activities of Daily Living (ADLs: bathing,
dressing, toileting, transferring, continence, feeding) and Instrumental ADLs (IADLs:
managing finances, medications, transportation, meal preparation), is foundational in
geriatric assessment because it directly reflects an individual's capacity for
independent living and guides care planning, resource allocation, and intervention
priorities.
Question 3: An 82-year-old patient with mild cognitive impairment is being
discharged home. Which intervention is most effective for reducing fall risk in this
population?
A. Prescribing a sedative-hypnotic for sleep improvement
B. Implementing a multifactorial fall prevention program including home safety
evaluation
,C. Recommending strict bed rest to minimize mobility-related risks
D. Increasing calcium and vitamin D supplementation alone
CORRECT ANSWER: B. Implementing a multifactorial fall prevention program
including home safety evaluation
Rationale: Evidence-based guidelines (e.g., from the American Geriatrics Society)
strongly support multifactorial fall prevention interventions for older adults at risk.
These include home hazard assessment and modification, medication review, vision
assessment, gait and balance training, and management of postural hypotension.
Single interventions like supplements or bed rest are insufficient and may increase risk.
Question 4: Which pharmacokinetic change in older adults most significantly
contributes to increased risk of drug toxicity with lipid-soluble medications?
A. Decreased gastric acid secretion
B. Increased total body water
C. Decreased lean body mass and increased body fat percentage
D. Enhanced renal tubular secretion
CORRECT ANSWER: C. Decreased lean body mass and increased body fat
percentage
Rationale: With aging, body composition shifts: lean body mass and total body water
decrease, while body fat percentage increases. Lipid-soluble drugs (e.g.,
benzodiazepines, antipsychotics) distribute more extensively into adipose tissue,
leading to a larger volume of distribution, prolonged half-life, and accumulation with
repeated dosing, thereby increasing toxicity risk. This necessitates dose adjustments
and careful monitoring.
Question 5: According to the Beers Criteria, which medication should generally be
avoided in older adults due to high anticholinergic burden and risk of confusion,
dry mouth, constipation, and urinary retention?
A. Lisinopril
B. Diphenhydramine
C. Metformin
D. Atorvastatin
CORRECT ANSWER: B. Diphenhydramine
Rationale: The AGS Beers Criteria® identify medications potentially inappropriate for
older adults. Diphenhydramine, a first-generation antihistamine with strong
anticholinergic properties, is listed due to its high risk of causing cognitive impairment,
delirium, constipation, urinary retention, and falls in older adults. Safer alternatives
(e.g., second-generation antihistamines) are recommended for allergy management.
,Question 6: An older adult presents with acute confusion, fluctuating attention,
and disorganized thinking that developed over 24 hours. Which condition should
the gerontological nurse prioritize in the differential diagnosis?
A. Alzheimer's disease
B. Delirium
C. Vascular dementia
D. Normal pressure hydrocephalus
CORRECT ANSWER: B. Delirium
Rationale: Delirium is characterized by acute onset (hours to days), fluctuating course,
inattention, and either disorganized thinking or altered level of consciousness. It is a
medical emergency often triggered by infection, medication changes, dehydration, or
metabolic derangements. Differentiating delirium from dementia is critical because
delirium is often reversible with prompt treatment of the underlying cause.
Question 7: Which communication strategy is most appropriate when interacting
with an older adult who has moderate hearing loss?
A. Speaking loudly and slowly directly into the unaffected ear
B. Using complex medical terminology to ensure precision
C. Facing the person, speaking clearly at a moderate pace, and minimizing background
noise
D. Relying solely on written instructions to avoid miscommunication
CORRECT ANSWER: C. Facing the person, speaking clearly at a moderate pace, and
minimizing background noise
Rationale: Effective communication with hearing-impaired older adults involves
optimizing the environment (reducing noise), ensuring visual cues (facing the person for
lip-reading and facial expressions), and using clear, moderate-paced speech without
shouting (which distorts sound). This approach respects dignity, enhances
understanding, and reduces frustration compared to shouting, complex jargon, or
exclusive written communication.
Question 8: In managing chronic pain in an older adult with osteoarthritis, which
principle should guide the gerontological nurse's approach?
A. Start with the highest effective opioid dose to ensure rapid relief
B. Use a multimodal approach prioritizing non-pharmacologic interventions and lowest
effective medication doses
C. Avoid all NSAIDs due to absolute contraindication in aging
D. Reserve acetaminophen for breakthrough pain only
CORRECT ANSWER: B. Use a multimodal approach prioritizing non-pharmacologic
interventions and lowest effective medication doses
, Rationale: Geriatric pain management emphasizes a multimodal strategy: non-
pharmacologic interventions (exercise, heat/cold, physical therapy) combined with
pharmacologic agents at the lowest effective dose for the shortest duration.
Acetaminophen is first-line for mild-moderate pain; NSAIDs require caution due to
GI/renal/cardiovascular risks; opioids are reserved for severe pain with careful
monitoring. This balances efficacy with safety in a population vulnerable to adverse
drug events.
Question 9: Which assessment tool is specifically validated for screening
depression in older adults and accounts for somatic symptoms that may overlap
with medical illness?
A. Mini-Mental State Examination (MMSE)
B. Geriatric Depression Scale (GDS)
C. Confusion Assessment Method (CAM)
D. Braden Scale
CORRECT ANSWER: B. Geriatric Depression Scale (GDS)
Rationale: The Geriatric Depression Scale (GDS), particularly the 15-item short form, is
designed for older adults. It minimizes reliance on somatic items (e.g., sleep, appetite
changes) that may reflect medical conditions rather than depression, focusing instead
on mood, cognition, and anhedonia. This enhances specificity for depression screening
in geriatric populations compared to tools like the MMSE (cognition) or CAM (delirium).
Question 10: An older adult with advanced dementia is experiencing difficulty
swallowing. Which intervention aligns with person-centered, palliative-focused
care?
A. Inserting a percutaneous endoscopic gastrostomy (PEG) tube routinely to ensure
nutrition
B. Offering small, frequent meals of preferred textures and consistency, with careful
monitoring for aspiration
C. Withholding all oral intake to prevent aspiration pneumonia
D. Administering thickened liquids exclusively without assessing patient preference
CORRECT ANSWER: B. Offering small, frequent meals of preferred textures and
consistency, with careful monitoring for aspiration
Rationale: In advanced dementia, feeding tubes do not improve survival, prevent
aspiration, or enhance quality of life, and may cause discomfort. Person-centered
palliative care prioritizes comfort, dignity, and patient preferences. Hand-feeding with
modified textures, allowing ample time, and honoring food preferences supports oral
intake while minimizing aspiration risk and maintaining the social and pleasurable
aspects of eating.
Question 11: Which physiological change in the aging integumentary system most
directly increases susceptibility to pressure injuries?
