Gerontological Nursing: 2026 Fall Prevention & Frailty
1. An 82-year-old female client is admitted to the gerontological unit. The nurse notes a significant loss
of skeletal muscle mass and strength, slow walking speed, and a subjective complaint of severe fatigue.
The nurse documents this syndrome of muscle mass loss as which of the following?
A. Sarcopenia
B. Cachexia
C. Senile osteopenia
D. Myasthenia gravis
Correct Answer: A. Sarcopenia
Rationale: Sarcopenia is defined as the age-associated, progressive loss of skeletal muscle mass, strength, and
physical performance. It is a key physiological component of frailty in older adults. Cachexia (B) is muscle
wasting driven by inflammatory cytokines and metabolic changes related to chronic disease (e.g., cancer, end-
stage renal disease). Senile osteopenia (C) refers to bone density loss. Myasthenia gravis (D) is an autoimmune
neuromuscular disease, not a normal age-related process.
2. The gerontological nurse is reviewing the relationship between age-related sensory changes and
balance in older adults. Which physiological alteration of the auditory-vestibular system directly
contributes to increased postural instability and dizziness?
A. Atrophy of the cerumen-producing glands.
B. Loss of sensory hair cells within the otolith organs and semicircular canals.
C. Sclerosis of the tympanic membrane.
D. Hypertrophy of the cochlear nerve.
Correct Answer: B. Loss of sensory hair cells within the otolith organs and semicircular canals.
Rationale: Postural stability relies on vestibular, visual, and proprioceptive inputs. Age-related degeneration and
loss of sensory hair cells within the vestibular otolith organs (utricle, saccule) and semicircular canals lead to
impaired vestibular-ocular reflexes and decreased spatial orientation, which directly causes balance instability and
dizziness. Tympanic sclerosis (C) and cerumen changes (A) affect conduction of sound waves, not balance.
Cochlear nerve fibers undergo atrophy rather than hypertrophy (D).
3. During a physical assessment, a 79-year-old male client reports difficulty standing stably with his
eyes closed and frequently stumbles when walking in the dark. The nurse should identify that this
clinical presentation is primarily due to age-related changes in which sensory modality?
A. Kinesthetic vision
B. Vestibular canal patency
C. Proprioception and deep joint position sensation
D. Dermal nociception
,Correct Answer: C. Proprioception and deep joint position sensation
Rationale: Proprioception is the unconscious awareness of joint position and movement in space. Age-related loss
of mechanoreceptors in joints and muscles, along with peripheral neuropathy, decreases proprioceptive feedback.
When vision is removed (eyes closed or in the dark), older adults struggle to maintain balance because they cannot
feel where their limbs are situated relative to the floor. Kinesthetic vision (A) is not a standard sensory term.
Vestibular patency (B) and dermal nociception (D) do not explain sensory deficit highlighted by loss of balance
specifically in dark environments.
4. An older adult client is being discharged home. The nurse discusses safety hazards on stairwells. The
client has age-related presbyopia and decreased contrast sensitivity. Which visual deficit must the
nurse address in the discharge safety plan?
A. Inability to distinguish high-pitched colors.
B. Inability to distinguish the edges of steps of similar colors.
C. Constant visual hallucinations in low light.
D. Loss of peripheral visual field sensitivity (tunnel vision).
Correct Answer: B. Inability to distinguish the edges of steps of similar colors.
Rationale: Contrast sensitivity decreases with age due to changes in the lens (yellowing and opacification) and
retina. Clients with poor contrast sensitivity find it difficult to distinguish objects from their backgrounds, such as
the edge of a step of a uniform stair design. Home modifications should include highlighting step edges with high-
contrast safety tape. Presbyopia is the loss of near-focus accommodation, not loss of peripheral fields (D) or color
pitch (A).
5. A 75-year-old client with age-related macular degeneration (AMD) is evaluated for fall risk. The
nurse should understand that macular degeneration primarily affects mobility by causing which visual
impairment?
A. Loss of central vision, hindering the ability to scan the path ahead for immediate hazards.
B. Loss of peripheral vision, preventing detection of hazards approaching from the sides.
C. Blurred vision at all distances due to abnormal corneal curvature.
D. Sudden double vision when looking downward.
Correct Answer: A. Loss of central vision, hindering the ability to scan the path ahead for immediate
hazards.
Rationale: Macular degeneration causes progressive destruction of the macula, resulting in loss of central vision
(scotomas). While peripheral vision remains intact, the lack of central vision prevents the client from clearly
identifying details in their immediate walking path, such as small cords, spills, or uneven tiles. Peripheral vision
loss (B) occurs in glaucoma. Corneal curvature abnormalities (C) cause astigmatism. Double vision (D) indicates
cranial nerve palsy or ocular muscle issues, not AMD.
,6. An 84-year-old client experiences a sudden drop in blood pressure when moving from a lying to a
standing position. The nurse understands that the primary age-related pathophysiological mechanism
behind this orthostatic hypotension is:
A. Increased elasticity of the aortic arch.
B. Decreased sensitivity of arterial baroreceptors.
C. Overproduction of renin and aldosterone.
D. Hyperactivity of the parasympathetic nervous system.
Correct Answer: B. Decreased sensitivity of arterial baroreceptors.
Rationale: Aging causes structural changes in arterial walls (stiffening), which decreases the sensitivity of
baroreceptors located in the carotid sinuses and aortic arch. Consequently, the rapid autonomic reflex (increase in
heart rate and vasoconstriction) that normally compensates for gravity-induced venous pooling upon standing is
delayed and blunted, causing orthostatic hypotension. Renin-aldosterone levels decrease with age (C), and arterial
elasticity is reduced (A). Parasympathetic response is not hyperactive (D).
7. During a clinical seminar, the presenter asks the students to differentiate between sarcopenia and
cachexia. Which statement by a student indicates correct understanding?
A. "Sarcopenia is always accompanied by severe cognitive decline, whereas cachexia is purely physical."
B. "Cachexia is driven by underlying inflammatory disease states and cannot be reversed solely by nutritional
intake, whereas sarcopenia is primarily age-related."
C. "Sarcopenia is the loss of bone mass, while cachexia is the loss of cardiac muscle mass."
D. "Cachexia is normal aging of the skeletal muscles, whereas sarcopenia is a disease-specific wasting
syndrome."
Correct Answer: B. "Cachexia is driven by underlying inflammatory disease states and cannot be reversed
solely by nutritional intake, whereas sarcopenia is primarily age-related."
Rationale: Sarcopenia is primarily an age-related loss of muscle mass and function, often exacerbated by physical
inactivity. Cachexia is a complex metabolic wasting syndrome associated with chronic illness (e.g., cancer,
COPD) driven by pro-inflammatory cytokines, which accelerate protein degradation; it cannot be reversed by
simple nutritional supplementation. Sarcopenia does not refer to bone loss (C, which is osteopenia/osteoporosis)
and is not inherently tied to cognitive decline (A).
8. The nurse is analyzing the gait characteristics of older adults to identify high-risk abnormalities.
Which gait change is considered a typical, compensatory age-related adaptation rather than a
pathological sign of neurological disease?
A. Unilateral foot drop during the swing phase.
B. Intermittent freezing of gait when initiating movement.
C. A slightly wider base of support and shorter, deliberate stride length.
D. Rhythmic, involuntary pill-rolling tremors of the hands during ambulation.
Correct Answer: C. A slightly wider base of support and shorter, deliberate stride length.
, Rationale: Typical age-related gait modifications include a wider stance (base of support), shorter step length, and
slightly decreased speed. These are compensatory adaptations to optimize balance and stability. Unilateral foot
drop (A), gait freezing (B), and pill-rolling tremor (D) are pathological findings indicative of neurological
conditions (e.g., peroneal nerve palsy, Parkinson's disease).
9. A 78-year-old male client reports sudden onset of room-spinning dizziness whenever he rolls over in
bed or tilts his head backward to look at high shelves. The nurse recognizes that these symptoms are
indicative of which common vestibular disorder?
A. Ménière's disease
B. Benign paroxysmal positional vertigo (BPPV)
C. Otosclerosis
D. Acoustic neuroma
Correct Answer: B. Benign paroxysmal positional vertigo (BPPV)
Rationale: BPPV is a common cause of vertigo in older adults. It is caused by calcium carbonate crystals
(otoconia) dislodging from the utricle and migrating into the semicircular canals (usually posterior). Positional
changes of the head (rolling in bed, tilting back) trigger abnormal movement of fluid, causing brief episodes of
vertigo. Ménière's disease (A) involves tinnitus, hearing loss, and attacks that last hours. Otosclerosis (C) causes
progressive hearing loss. Acoustic neuroma (D) causes progressive unilateral sensorineural hearing loss and
constant balance issues.
10. The nurse is screening a community-dwelling older adult client for frailty using Fried's Frailty
Phenotype. Which set of criteria constitutes this assessment model?
A. Age over 85, history of diabetes, polypharmacy, visual impairment, and low income.
B. Cognitive decline, urinary incontinence, depression, dysphagia, and poor family support.
C. Unintentional weight loss, self-reported exhaustion, low physical activity level, slow gait speed, and weak
grip strength.
D. High blood pressure, sedentary lifestyle, high cholesterol, smoking history, and history of stroke.
Correct Answer: C. Unintentional weight loss, self-reported exhaustion, low physical activity level, slow gait
speed, and weak grip strength.
Rationale: Fried's Frailty Phenotype identifies frailty based on five clinical criteria: 1) Unintentional weight loss
(10 lbs or more in the past year), 2) Self-reported exhaustion, 3) Weakness (measured by grip strength), 4) Slow
walking speed (gait speed over 15 feet), and 5) Low physical activity level. An individual is classified as frail if
they meet 3 or more of these criteria, and pre-frail if they meet 1 or 2. The other options contain general risk
factors but do not represent the validated Fried phenotype.
11. When assessing a client's grip strength as part of a comprehensive frailty evaluation, which
protocol should the nurse follow to ensure reliability?
A. Use a manual dynamometer, test only the non-dominant hand once, and record the value.
