NUR 257 Exams 1-4 - Concepts of Aging & Chronic Illness -
(2026) Actual Questions & Answers (GCN) 100% Guarantee
Pass - 99 Questions

This exam section rigorously evaluates understanding of the major biological, psychological, and sociological
theories of aging. Questions require integration of theoretical principles with clinical reasoning, critical analysis
of research findings, and application to complex care scenarios. Content reflects current gerontological
frameworks and evidence-based practice. It contains 99 multiple-choice questions, each with four distractors and
a fully worked rationale that explains why the keyed answer is correct. Content is organized into 10 focused
sections: Theories of Aging, Physiological Changes with Aging, Psychosocial Aspects of Aging, Chronic Illness
Management, Pharmacology in Older Adults, Pain Management in Older Adults, Nutrition and Hydration, Safety
and Fall Prevention, End-of-Life Care, Ethical and Legal Issues. Targeted learning outcomes include: Critically
compare and contrast major theories of aging (e.g., programmed, damage/error, psychosocial, and
gerotranscendence).; Evaluate the evidence supporting each theory and identify clinical implications for nursing
care of older adults.; Apply theoretical concepts to explain age-related physiological changes, disease processes,
and psychosocial adaptations.. Every item has been reviewed for clinical accuracy, current guidelines, and clarity
so that students can study with confidence and self-correct as they work through the bank. Use it as a high-yield
review immediately before the exam, or as a structured practice tool during the unit - the rationales double as
concise teaching notes. The recommended writing time is 3 hours, with a passing score of 90%. Aligned with

Section 1: Theories of Aging (Questions 1-10)

1 A researcher proposes that aging results from the accumulation of somatic
mutations in mitochondrial DNA, leading to energy decline. This hypothesis is
most consistent with which theory of aging?
A) Free radical theory
B) Error catastrophe theory
C) Somatic mutation theory
D) Wear-and-tear theory
Answer: C
Rationale: The somatic mutation theory posits that aging is caused by the gradual
accumulation of mutations in nuclear and mitochondrial DNA, impairing cellular
function. The free radical theory focuses on oxidative damage, error catastrophe on
protein synthesis errors, and wear-and-tear on cumulative mechanical and metabolic
stress.

2 In a longitudinal study, participants who maintained high levels of social
integration and productive activity showed slower cognitive decline compared to
isolated peers. This finding best supports which psychosocial theory of aging?
A) Disengagement theory
B) Activity theory
C) Continuity theory

,D) Selective optimization with compensation (SOC)
Answer: B
Rationale: Activity theory asserts that continued engagement in social and productive
roles promotes well-being and cognitive health in later life. Disengagement theory
posits mutual withdrawal, continuity theory emphasizes maintaining consistent
patterns, and SOC focuses on adaptive selection and optimization.

3 A gerontologist argues that aging is primarily due to the shortening of telomeres
with each cell division, eventually triggering replicative senescence. This is a key
mechanism of which theory?
A) Programmed senescence theory
B) Neuroendocrine theory
C) Immunological theory
D) Rate-of-living theory
Answer: A
Rationale: Programmed senescence theory holds that aging follows a biological
timetable, with telomere attrition as a cellular clock. Neuroendocrine theory focuses
on hormonal changes, immunological theory on immune decline, and rate-of-living
theory on metabolic rate and lifespan.

4 An older adult who was a meticulous accountant in midlife now organizes daily
activities with elaborate lists and routines. Which theory best explains this
behavioral continuity?
A) Gerotranscendence theory
B) Continuity theory
C) Role theory
D) Exchange theory
Answer: B
Rationale: Continuity theory proposes that individuals maintain consistent patterns of
behavior, personality, and relationships as they age. Gerotranscendence involves a
shift in perspective toward cosmic awareness, role theory focuses on role transitions,
and exchange theory on cost-benefit social interactions.

5 A study finds that calorie-restricted mice have lower levels of insulin-like growth
factor 1 (IGF-1) and live longer. This finding is most directly consistent with
which theory of aging?
A) Free radical theory
B) Neuroendocrine theory

,C) Rate-of-living theory
D) Mitochondrial theory
Answer: B
Rationale: Neuroendocrine theory emphasizes the role of hormonal changes (e.g.,
reduced IGF-1, growth hormone) in aging. Calorie restriction modulates these
pathways. Free radical theory focuses on oxidative damage, rate-of-living on
metabolic rate, and mitochondrial theory on energy decline.

6 An older adult reports feeling a shift from materialistic concerns to a more cosmic
perspective, with increased satisfaction in solitude. This aligns with which theory?
A) Disengagement theory
B) Gerotranscendence theory
C) Activity theory
D) Stratification theory
Answer: B
Rationale: Gerotranscendence theory describes a developmental shift toward
wisdom, decreased focus on material possessions, and increased existential
well-being. Disengagement theory is about mutual withdrawal, activity theory
emphasizes engagement, and stratification theory addresses social inequality.

7 Which theory of aging would most directly predict that individuals with higher
baseline metabolic rates have shorter lifespans?
A) Wear-and-tear theory
B) Rate-of-living theory
C) Programmed senescence theory
D) Cross-linking theory
Answer: B
Rationale: Rate-of-living theory proposes that organisms with higher metabolic rates
age faster and die sooner due to greater cumulative metabolic damage.
Wear-and-tear theory is broader, programmed senescence is about genetic
timetables, and cross-linking theory focuses on protein cross-links.

8 A researcher observes that older adults who adopt new hobbies and maintain
flexible coping strategies show better adaptation. This observation is most
consistent with which model?
A) Selective optimization with compensation (SOC)
B) Disengagement theory
C) Continuity theory

, D) Role theory
Answer: A
Rationale: SOC model describes adaptation through selection (focusing on key
goals), optimization (enhancing resources), and compensation (using alternative
strategies). Disengagement theory predicts withdrawal, continuity theory predicts
stability, and role theory focuses on role changes.

9 An older patient with multiple comorbidities reports feeling that life has been
meaningful and has no fear of death. This attitude is best explained by which
theory?
A) Erikson's psychosocial theory (integrity vs. despair)
B) Disengagement theory
C) Activity theory
D) Continuity theory
Answer: A
Rationale: Erikson's theory posits that in late life, individuals reflect on their lives;
achieving integrity leads to acceptance and wisdom, while despair results from
regret. Disengagement, activity, and continuity theories do not specifically address
life review and acceptance of mortality.

10 A study demonstrates that caloric restriction extends lifespan in yeast by
activating sirtuin genes. This mechanism is most closely linked to which theory
of aging?
A) Programmed longevity theory
B) Free radical theory
C) Mitochondrial theory
D) Wear-and-tear theory
Answer: A
Rationale: Programmed longevity theory (a branch of programmed senescence) holds
that aging is regulated by specific genes (e.g., sirtuins) and pathways. Free radical
theory focuses on oxidative damage, mitochondrial theory on energy decline, and
wear-and-tear on cumulative stress.

Section 2: Physiological Changes with Aging (Questions 11-20)

11 Which cellular mechanism is primarily responsible for the age-related decline in
skeletal muscle mass and strength, independent of neuronal loss?
A) Increased autophagy leading to myofiber apoptosis
