BSN 425: Gerontological Nursing Comprehensive
Exam
Question 1
An 82-year-old female resident at a long-term care facility is
being evaluated by the nurse following a gradual decline in her
functional mobility over the past six months. The nurse applies
the Functional Independent Measure (FIM) and the Katz Index
of Independence in Activities of Daily Living (ADL). Which of
the following statements best describes the primary clinical
utility of utilizing the Katz ADL index in gerontological nursing
practice? [1]
• Option A: It measures advanced cognitive functioning,
executive decision-making, and financial management
capabilities. Rationale: Incorrect. The Katz ADL index
is strictly limited to basic physiological self-care tasks,
not complex instrumental skills or executive brain
function.
• Option B: It assesses basic performance in six
primary socio-demographic areas including
bathing, dressing, toileting, transferring,
continence, and feeding. Rationale: Correct. The
Katz ADL tool is the gold standard in gerontological care
for objectively establishing an older adult's baseline
, independence or decline in basic physical self-care
functions.
• Option C: It predicts long-term cardiovascular mortality
risks and anesthetic tolerance for surgical clearance.
Rationale: Incorrect. The tool is an administrative and
functional assessment instrument, carrying no
physiological predictive modeling for anesthesia or
cardiac structures.
• Option D: It screens for underlying clinical depression and
age-related sleep cycle disruptions. Rationale:
Incorrect. Deprative states and sleep metrics are
evaluated using targeted psychological tools like the
Geriatric Depression Scale (GDS).
Question 2
A 78-year-old male is admitted to the medical-surgical unit
with a diagnosis of acute urosepsis. Over a 12-hour period, the
nurse notes that the patient has become increasingly agitated, is
experiencing vivid visual hallucinations of insects on the wall,
and exhibits a fluctuating level of consciousness. A review of his
baseline chart reveals he was fully oriented upon admission.
What acute medical condition is this clinical change indicative
of, and what is the standard tool used to confirm it?
• Option A: Major Neurocognitive Disorder (Dementia),
confirmed via the Mini-Mental State Examination
(MMSE). Rationale: Incorrect. Dementia features a
slow, progressive, irreversible structural decline in
memory, completely lacking the rapid, fluctuating onset
described here.
• Option B: Acute Schizophrenia spectrum flare, confirmed
using the Patient Health Questionnaire-9 (PHQ-9).
Rationale: Incorrect. Late-onset schizophrenia is highly
, uncommon, and the PHQ-9 is a specific mood assessment
tool for depression, not active psychosis screening.
• Option C: Delirium, confirmed via the Confusion
Assessment Method (CAM). Rationale: Correct.
Delirium is characterized by an acute, fluctuating onset
of altered cognition and orientation, often triggered by
underlying systemic infections like a UTI. The CAM is the
definitive screening instrument used to identify it.
• Option D: Normal age-related cognitive drift, confirmed
via a routine cranial computed tomography (CT) layout
scan. Rationale: Incorrect. Hallucinations, acute
orientation drops, and shifting consciousness are severe
clinical emergencies, never benign signs of normal aging.
Question 3
A nurse is reviewing the medication profile of a 72-year-old
male patient who reports chronic insomnia and generalized
anxiety. The profile reveals a current prescription for
diphenhydramine 50 mg orally at bedtime. According to the
American Geriatrics Society (AGS) Beers Criteria for Potentially
Inappropriate Medication Use in Older Adults, why should this
medication be strictly avoided or discontinued?
• Option A: It causes acute renal papillary necrosis and
accelerates permanent glomerular filtration failure.
Rationale: Incorrect. Diphenhydramine does not carry
a black-box structural risk for inducing direct renal
papillary tissue destruction.
• Option B: It induces severe iron deficiency anemia by
binding to mucosal receptors in the duodenum.
Rationale: Incorrect. Antihistamines do not
structurally bind to or block the dietary absorption of
micro-nutrients or elemental iron.
, • Option C: It possesses potent anticholinergic
properties that significantly increase the risks of
confusion, blurred vision, urinary retention, dry
mouth, and falls. Rationale: Correct. First-
generation antihistamines like diphenhydramine are
highly anticholinergic, posing severe safety, cognitive,
and balance risks to the gerontological population.
• Option D: It triggers dangerous systemic hyperkalemia
when taken alongside regular dietary sodium sources.
Rationale: Incorrect. Potassium homeostasis is
completely independent of standard diphenhydramine
pharmacodynamics.
Question 4
A 69-year-old female presents to the community wellness clinic
reporting progressive difficulty hearing conversations in
crowded rooms. She states that higher-pitched voices, such as
those of her granddaughters, sound muffled and unclear, while
lower-pitched male voices are easier to understand. The nurse
documents this finding as presbyacusis. What is the underlying
structural etiology of this age-related sensorineural alteration?
• Option A: Hypertrophy and stiffening of the tympanic
membrane structures. Rationale: Incorrect. Stiffening
of the tympanic membrane or ossicular chain leads to
conductive hearing loss, not specific high-frequency
sensorineural presbyacusis.
• Option B: Excessive build-up of dry cerumen blocking the
external auditory canal. Rationale: Incorrect. Cerumen
impaction is a mechanical, conductive barrier that
dampens all sound frequencies uniformly, rather than a
selective sensorineural loss.
• Option C: Degeneration of the organ of Corti and
progressive loss of hair cells in the basal turn of
