Gerontology Comprehensive Final Examination
1. Biological Theories & Physiological Changes of Aging
1. An 82-year-old female presents to the clinic with an
increased susceptibility to infections and a history of delayed
wound healing. Laboratory results indicate a significant
reduction in T-cell differentiation and functionality, despite a
relatively stable total lymphocyte count. Which biological
theory of aging best explains these physiological changes?
A. Free Radical Theory
B. Immunosenescence / Neuroendocrine Theory
C. Wear and Tear Theory
D. Cross-Linking Theory
CORRECT ANSWER: B
RATiONAlE: Immunosenescence refers to the
progressive decline of the immune system associated with
aging. It primarily affects cell-mediated immunity (T-cells),
leading to involution of the thymus gland, decreased
response to novel antigens, and delayed wound healing.
2. During a routine physical examination of a 78-year-old male,
the nurse notes an increase in systolic blood pressure from
, 124 mmHg to 142 mmHg over the past five years, while the
diastolic blood pressure remains stable at 78 mmHg. This
widening pulse pressure is primarily driven by which age-
related cardiovascular alteration?
A. Proliferation of myocardial beta-receptors
B. Decreased peripheral vascular resistance
C. Arterial stiffening due to collagen cross-linking and elastin
degradation
D. Hypertrophy of the right ventricle
CORRECT ANSWER: C
RATiONAlE: Age-related structural changes in the
arterial walls include a decrease in elastin and an
overproduction/cross-linking of collagen. This leads to
increased arterial stiffness, causing an elevation in systolic
blood pressure and a widened pulse pressure, a condition
known as isolated systolic hypertension.
3. A 74-year-old patient reports that food "just doesn't taste the
same anymore," leading to a decreased appetite and
unintended weight loss. When assessing this clinical finding,
which physiological change should the clinician recognize as
a normal consequence of the aging gustatory system?
A. Complete atrophy of the circumvallate papillae
B. A decline in the total number of taste buds and a
reduction in olfactory sensitivity
C. Hyper-regeneration of mechanoreceptors in the oral
mucosa
D. Increased salivary production causing flavor dilution
CORRECT ANSWER: B
, RATiONAlE: Normal aging involves a gradual reduction
in the density of taste buds, particularly after age 70,
alongside a prominent decline in olfactory function
(anosmia/hyposmia). Because flavor perception is heavily
reliant on olfaction, food often tastes bland to older adults.
4. A 79-year-old resident in a long-term care facility
experiences frequent nocturnal awakenings and complains of
feeling unrefreshed in the morning. A polysomnography
study reveals a marked decrease in slow-wave sleep (Stage
N3) and frequent arousals. How should the gerontological
nurse interpret this finding?
A. An abnormal manifestation indicating early-stage vascular
dementia
B. A normal, age-expected shift in sleep architecture
C. A classic symptom of severe clinical depression in older
adults
D. An adverse effect typically caused by a lack of daytime
physical activity
CORRECT ANSWER: B
RATiONAlE: Sleep architecture shifts predictably with
aging. There is a physiological decrease in deep, slow-wave
non-REM sleep (Stage N3) and REM sleep, resulting in
lighter, more fragmented sleep and more frequent
spontaneous awakenings.
5. A 68-year-old postmenopausal female is being evaluated for
osteoporosis. The clinician explains that age-related bone
loss is accelerated by the cellular imbalance between
osteoblast and osteoclast activity. Which mechanism
, represents the primary biological driver of this accelerated
bone resorption?
A. Decreased parathyroid hormone (PTH) secretion
B. Chronic upregulation of calcitonin production
C. Estrogen deficiency leading to increased lifetime and
activity of osteoclasts
D. Impaired absorption of dietary iron in the duodenum
CORRECT ANSWER: C
RATiONAlE: Estrogen naturally suppresses bone
resorption by limiting the lifespan and activity of
osteoclasts. Postmenopausal estrogen withdrawal removes
this protective brake, accelerating bone loss and
predisposing women to osteoporosis.
2. Pharmacokinetics, Pharmacodynamics &
Polypharmacy
6. An 85-year-old male is prescribed a highly lipophilic
medication. When calculating the appropriate dosage
titration, the clinical pharmacist must account for which
normal age-related change in body composition?
A. Decreased total body fat percentage
B. Increased total body water volume
C. Increased proportion of adipose tissue relative to lean
muscle mass
D. Elevated serum albumin concentrations
CORRECT ANSWER: C
RATiONAlE: With aging, lean muscle mass and total
