NUR 2214 Nursing Care of the Older Adult Quiz 4 Comprehensive Examination 2026/2027 | Verified Questions
,Introduction
This examination contains 50 original Verified Questions organized into four core domains that follow the
official blueprint of the Rasmussen College NUR 2214 Nursing Care of the Older Adult course: Domain 1,
Gerontological Nursing Models and Theories, with 13 questions; Domain 2, Cognitive and Sensory
Alterations in Older Adults, with 13 questions; Domain 3, Mobility, Safety, and Fall Prevention, with 12
questions; and Domain 4, Pharmacological Management and Polypharmacy in Aging, with 12 questions.
Every question includes four choices, the correct response, and a rationale that explains the clinical
reasoning.
All content in this document is original and has been written to reinforce the official Rasmussen College
NUR 2214 course objectives for Quiz 4, supporting actual exam readiness and clinical proficiency in older
adult nursing care for University-Level nursing students in the 2026/2027 academic year. The questions
and rationales follow the foundational gerontological nursing methodology of the NUR 2214 course
materials, Ebersole and Hess' Toward Healthy Aging, and Meiner's Gerontologic Nursing, and they align
with current evidence-based geriatric clinical standards and older adult safety guidelines. A full answer
key and a per-domain score tracker are provided at the end so that each domain can be checked and used
to focus further study.
Actual Questions
Domain 1: Gerontological Nursing Models and Theories
Question 1. Which biologic theory of aging proposes that cellular damage accumulates
from unstable oxygen molecules produced during normal metabolism?
A. The cross-linking theory
B. The free radical theory
C. The neuroendocrine theory
D. The programmed aging theory
Correct Answer: B
Rationale: The free radical theory, proposed by Harman, holds that oxygen free radicals produced
during metabolism damage cell membranes, DNA, and proteins, and that this cumulative oxidative
injury underlies age-related decline. The NUR 2214 course materials and Ebersole and Hess' Toward
Healthy Aging present this theory alongside the role of antioxidants such as vitamins C and E in
limiting oxidative stress. Cross-linking theory addresses connective tissue stiffening, neuroendocrine
theory addresses hormonal regulation, and programmed aging theory addresses genetically timed
cellular events.
Question 2. What does the Hayflick limit describe in cellular aging research?
A. The maximum number of divisions a human cell can undergo before senescence
B. The maximum heart rate achieved during exercise in older adults
C. The number of chromosomes lost with each cell division
D. The point at which body temperature regulation declines
Correct Answer: A
Rationale: The Hayflick limit is the observation that normal human cells divide only a finite number of
times, roughly 40 to 60 divisions in culture, before entering senescence, and it supports the
programmed aging perspective that cellular replication capacity is genetically limited. This concept,
taught in the NUR 2214 curriculum and Meiner's Gerontologic Nursing, explains why telomere
shortening accompanies repeated division. It does not describe cardiovascular performance,
chromosome loss, or thermoregulation.
Question 3. The cross-linking theory of aging attributes age-related tissue changes to which
mechanism?
A. Gradual loss of neurons in the cerebral cortex only
B. Declining antibody production in the thymus
C. Accumulation of iron deposits in joint cartilage
D. Progressive bonding of collagen and elastin fibers that stiffens connective tissue
NUR 2214 Nursing Care of the Older Adult Quiz 4 Comprehensive Examination 2026/2027 | Verified Questions
, Correct Answer: D
Rationale: Cross-linking theory holds that chemical bonds form between collagen and elastin molecules
over time, making connective tissue less elastic and contributing to stiffened joints, thickened blood
vessels, and reduced skin turgor. It is one of the structural biologic theories discussed with the free
radical and immunologic theories in the NUR 2214 course materials. Neuronal loss is addressed by
neurobiologic theories, and thymic antibody decline belongs to the immunologic theory of aging.
Question 4. Which age-related change best illustrates the immunologic (immune
senescence) theory of aging?
A. Reduced T-cell function and increased susceptibility to infection and malignancy
B. Increased antibody diversity with advancing age
C. Enhanced neutrophil chemotaxis in older adults
D. Rising thymic hormone output after age 65
Correct Answer: A
Rationale: Immunosenescence involves involution of the thymus, reduced naive T-cell production, and
diminished cell-mediated immunity, which increases vulnerability to infections, cancer, and
autoimmune disorders, and weakens vaccine responses. The immunologic theory and its clinical
consequences are emphasized in the NUR 2214 course materials and Ebersole and Hess' Toward
Healthy Aging. Antibody diversity, neutrophil function, and thymic hormone output all decline rather
than increase with age.
Question 5. Which statement is consistent with the neuroendocrine theory of aging?
A. The thymus enlarges and produces more T-cells with age
B. Age-related changes in hypothalamic-pituitary regulation contribute to declining hormone levels
and resilience
C. Bone density increases when parathyroid hormone falls
D. The adrenal glands become the sole source of sex steroids in later life
Correct Answer: B
Rationale: The neuroendocrine theory proposes that the hypothalamus and pituitary, as master
regulators, gradually lose efficiency, altering hormone secretion such as growth hormone, melatonin,
cortisol, and sex steroids, and impairing the body's stress response and homeostatic reserve. This
framework is presented in the NUR 2214 course materials and Meiner's Gerontologic Nursing when
discussing the multisystem impact of aging. Thymic involution, reduced bone density, and adrenal
changes are separate, well-documented phenomena that do not match this theory's tenets.
Question 6. According to Erikson's psychosocial theory, which developmental task is the
focus of late adulthood?
A. Generativity versus stagnation
B. Intimacy versus isolation
C. Identity versus role confusion
D. Integrity versus despair
Correct Answer: D
Rationale: Erikson's eighth stage, integrity versus despair, characterizes late adulthood, when older
adults reflect on their lives and achieve a sense of coherence and satisfaction or fall into regret and
despair. Successfully resolving this stage supports acceptance of mortality and wisdom. Generativity
versus stagnation is the seventh stage of middle adulthood, intimacy versus isolation belongs to young
adulthood, and identity versus role confusion to adolescence, all prior stages on the continuum.
Question 7. An 82-year-old continues volunteer work, attends church, and mentors
younger neighbors. Which theory of aging best supports this behavior as contributing to
successful aging?
A. Cumming and Henry's disengagement theory
B. The free radical theory
C. Havighurst's activity theory
D. The cross-linking theory
Correct Answer: C
