APPLICATION MCQS AND RATIONALES
CHALLENGING AND DETAILED
1. A 78-year-old female patient is admitted with a fractured
hip. Her daughter notes that over the past two days, the
patient has become increasingly confused, agitated, and is
seeing "bugs on the wall." The patient has a history of mild
osteoarthritis but no cognitive impairment. Which of the
following is the most likely explanation for this sudden
change?
A. Early-onset Alzheimer's disease
B. Age-related benign senescent forgetfulness
C. Delirium secondary to an underlying acute physiological
stressor
D. Late-onset schizophrenia
CORRECT ANSWER: C
RATiONAlE: Delirium is characterized by an acute,
fluctuating change in mental status, global cognitive
impairments, and altered levels of consciousness or
hallucinations, often triggered by acute illness, trauma, or
infections in older adults. Alzheimer's disease is a slow,
progressive decline.
2. When reviewing the medication profile of an 82-year-old
male, the gerontological nurse practitioner notes that the
patient is taking a first-generation antihistamine for seasonal
allergies. According to the Beers Criteria, why is this class of
, medication potentially inappropriate for this patient?
A. High risk of severe anticholinergic effects, including
urinary retention and falls
B. Increased risk of severe hepatotoxicity in patients over 80
C. Accelerated clearance leading to complete therapeutic
failure
D. Tendency to cause paradoxical severe hypertension
CORRECT ANSWER: A
RATiONAlE: The Beers Criteria lists first-generation
antihistamines as potentially inappropriate medications (PIMs)
for older adults due to their potent anticholinergic properties,
which significantly increase the risk of confusion, blurred vision,
dry mouth, urinary retention, constipation, and falls.
3. An 85-year-old individual experiences a gradual decline in
the ability to hear high-pitched sounds, making it difficult to
understand conversations in a crowded room. This
physiological, age-related sensorineural hearing loss is
medically termed:
A. Otosclerosis
B. Presbycusis
C. Tinnitus
D. Presbyopia
CORRECT ANSWER: B
RATiONAlE: Presbycusis is the age-related, progressive,
bilateral sensorineural hearing loss that most notably impacts
the perception of high-frequency sounds, making speech
discrimination difficult in noisy environments.
, 4. A gerontological nurse is educating a group of older adults
about normal age-related changes in the cardiovascular
system. Which physiological alteration should the nurse
include as a normal part of the aging process?
A. Increased elasticity of arterial walls
B. Increased maximum heart rate during intense exercise
C. Decreased myocardial excitability
D. Increased rigidity and thickening of the heart valves
CORRECT ANSWER: D
RATiONAlE: Normal cardiovascular aging involves the
accumulation of collagen and calcium deposits within heart
valves, leading to thickening and rigidity. Arterial walls become
less elastic (more stiff), and maximum heart rate decreases with
age.
5. A 79-year-old patient with advanced Parkinson's disease
exhibits severe dysphagia. During a meal, the patient begins
coughing weakly and develops a raspy voice. What is the
priority nursing intervention?
A. Immediately perform the Heimlich maneuver
B. Halt the meal immediately, position the patient fully
upright, and assess for aspiration
C. Administer a PRN dose of an oral anticholinergic
medication
D. Encourage the patient to drink a large glass of water to
clear the airway
CORRECT ANSWER: B
RATiONAlE: Weak coughing and a change in vocal quality
, ("wet" or raspy voice) during oral intake are strong indicators of
silent or active aspiration. The meal must be stopped
immediately to protect the airway, the patient positioned to
optimize airway clearance, and further clinical assessment
performed.
6. Which biological theory of aging asserts that highly reactive
molecules with an unpaired electron damage cell
membranes, proteins, and DNA, ultimately leading to tissue
degradation and organismal aging?
A. Wear and Tear Theory
B. Free Radical Theory
C. Cross-Linking Theory
D. Neuroendocrine Theory
CORRECT ANSWER: B
RATiONAlE: The Free Radical Theory of aging posits that
oxidative damage caused by reactive oxygen species (ROS) or
free radicals causes cumulative cellular dysfunction and
structural damage over time, contributing to the aging process.
7. An 81-year-old patient is prescribed a lipophilic medication.
The nurse understands that age-related changes in body
composition will alter the pharmacokinetics of this drug in
which specific manner?
A. Decreased volume of distribution, leading to rapid drug
clearance
B. Decreased half-life due to rapid hepatic metabolism
C. Increased volume of distribution, resulting in a prolonged
half-life and extended duration of action
