Clinical Judgment Review
Question 1: Which physiological change associated with aging most significantly
contributes to altered drug metabolism in older adults?
A. Decreased gastric acid production
B. Reduced hepatic blood flow and enzyme activity
C. Increased adipose tissue distribution
D. Diminished renal tubular secretion
CORRECT ANSWER: B. Reduced hepatic blood flow and enzyme activity
Rationale: Aging is associated with a 30-50% reduction in hepatic blood flow and
decreased cytochrome P450 enzyme activity, which significantly impairs the
metabolism of many medications. This pharmacokinetic change increases the risk of
drug accumulation and toxicity in older adults, making dose adjustments essential for
hepatically metabolized medications.
Question 2: An 82-year-old patient with moderate Alzheimer's disease becomes
agitated during evening care. Which non-pharmacological intervention should the
nurse implement first?
A. Administer prescribed lorazepam
B. Reduce environmental stimuli and use calm redirection
C. Restrain the patient to prevent injury
D. Increase the room lighting to improve visibility
CORRECT ANSWER: B. Reduce environmental stimuli and use calm redirection
Rationale: Non-pharmacological interventions are the first-line approach for managing
behavioral symptoms in dementia. Reducing noise, maintaining a predictable routine,
and using gentle redirection address potential triggers like overstimulation or unmet
needs without the risks associated with sedatives or restraints, which can worsen
confusion and increase fall risk.
Question 3: Which assessment finding is most indicative of delirium rather than
dementia in an older adult?
A. Gradual memory decline over two years
B. Fluctuating level of consciousness with acute onset
C. Inability to recognize familiar family members
D. Progressive difficulty with instrumental activities of daily living
CORRECT ANSWER: B. Fluctuating level of consciousness with acute onset
,Rationale: Delirium is characterized by acute onset (hours to days), fluctuating
consciousness, inattention, and disorganized thinking, often reversible with treatment
of the underlying cause. Dementia presents with gradual, progressive cognitive decline.
The acute, fluctuating nature is the key differentiator requiring urgent medical
evaluation.
Question 4: When assessing an older adult for fall risk, which tool is specifically
validated for use in community-dwelling elderly?
A. Braden Scale
B. Morse Fall Scale
C. Timed Up and Go Test
D. Glasgow Coma Scale
CORRECT ANSWER: C. Timed Up and Go Test
Rationale: The Timed Up and Go Test (TUG) is a validated, reliable screening tool for fall
risk in community-dwelling older adults. It assesses mobility, balance, and functional
ability by timing how long it takes a person to rise from a chair, walk 3 meters, turn,
return, and sit. The Morse Fall Scale is used in acute care; Braden assesses pressure
injury risk; Glasgow Coma Scale evaluates consciousness.
Question 5: Which medication class should be used with extreme caution in older
adults due to high risk of anticholinergic side effects like confusion, constipation,
and urinary retention?
A. ACE inhibitors
B. First-generation antihistamines
C. Statins
D. Proton pump inhibitors
CORRECT ANSWER: B. First-generation antihistamines
Rationale: First-generation antihistamines (e.g., diphenhydramine) possess strong
anticholinergic properties that cross the blood-brain barrier, increasing risks of
cognitive impairment, delirium, dry mouth, constipation, and urinary retention in older
adults. The Beers Criteria explicitly recommend avoiding these agents in geriatric
populations due to unfavorable risk-benefit profiles.
Question 6: An older adult with heart failure reports increased shortness of breath
and 3-pound weight gain over two days. Which nursing action is the priority?
A. Schedule a routine follow-up appointment
B. Assess for peripheral edema and lung sounds, then notify provider
C. Encourage increased oral fluid intake
D. Administer a PRN antianxiety medication
CORRECT ANSWER: B. Assess for peripheral edema and lung sounds, then notify
provider
,Rationale: Rapid weight gain and worsening dyspnea in heart failure suggest fluid
overload and potential decompensation. Immediate assessment of volume status
(edema, crackles, JVD) and prompt provider notification are critical to adjust diuretic
therapy and prevent hospitalization. Delaying intervention or increasing fluids could
worsen the condition.
Question 7: Which statement by an older adult with osteoporosis indicates
understanding of fall prevention strategies?
A. "I will wear loose slippers around the house for comfort."
B. "I will remove throw rugs and install grab bars in the bathroom."
C. "I will avoid using my walker indoors to maintain strength."
D. "I will take my sedative medication before walking to the bathroom at night."
CORRECT ANSWER: B. "I will remove throw rugs and install grab bars in the
bathroom."
Rationale: Environmental modifications like removing tripping hazards (throw rugs) and
installing assistive devices (grab bars) are evidence-based fall prevention strategies.
Loose footwear, avoiding prescribed assistive devices, and sedating medications before
ambulation increase fall risk and contradict safety education for osteoporosis
management.
Question 8: What is the primary goal of palliative care for an older adult with
advanced chronic obstructive pulmonary disease?
A. Cure the underlying disease process
B. Aggressively pursue all life-prolonging treatments
C. Optimize quality of life and manage symptoms
D. Expedite transfer to a long-term care facility
CORRECT ANSWER: C. Optimize quality of life and manage symptoms
Rationale: Palliative care focuses on relieving suffering and improving quality of life
through comprehensive symptom management, psychosocial support, and alignment
of care with patient goals, regardless of prognosis. It is appropriate at any stage of
serious illness and is distinct from hospice care, which is for end-of-life when curative
treatments are no longer pursued.
Question 9: Which finding during a nutritional assessment of an older adult
warrants immediate intervention?
A. Body mass index of 24 kg/m²
B. Unintentional weight loss of 10 pounds in one month
C. Preference for soft foods due to denture discomfort
D. Occasional forgetfulness about taking vitamin supplements
CORRECT ANSWER: B. Unintentional weight loss of 10 pounds in one month
, Rationale: Unintentional weight loss exceeding 5% of body weight in one month is a red
flag for malnutrition, underlying pathology (e.g., malignancy, depression, dysphagia), or
inadequate intake in older adults and requires comprehensive evaluation. BMI of 24 is
normal; denture issues and occasional supplement forgetfulness are common and
manageable with support.
Question 10: When communicating with an older adult who has moderate hearing
loss, which strategy is most effective for the nurse?
A. Speak loudly and sharply to ensure clarity
B. Face the patient directly, speak clearly at a moderate pace, and minimize background
noise
C. Use complex medical terminology to convey professionalism
D. Rely solely on written instructions without verbal explanation
CORRECT ANSWER: B. Face the patient directly, speak clearly at a moderate pace,
and minimize background noise
Rationale: Effective communication with hearing-impaired older adults involves facing
the patient to allow lip-reading, speaking clearly (not shouting, which distorts sound),
reducing background noise, and confirming understanding. Shouting can be perceived
as anger; complex terminology increases confusion; written instructions alone may not
accommodate visual or cognitive limitations.
Question 11: Which laboratory value requires careful interpretation in older adults
due to age-related physiological changes?
A. Hemoglobin A1c
B. Serum creatinine
C. Thyroid-stimulating hormone
D. Vitamin D level
CORRECT ANSWER: B. Serum creatinine
Rationale: Age-related decline in muscle mass reduces creatinine production, so serum
creatinine levels may appear "normal" even when glomerular filtration rate (GFR) is
significantly reduced. Estimated GFR (eGFR) using age-adjusted equations is more
accurate for assessing renal function in older adults to guide medication dosing and
detect chronic kidney disease.
Question 12: An older adult with vascular dementia exhibits sudden worsening of
confusion and left-sided weakness. Which condition should the nurse suspect
first?
A. Progression of dementia
B. Urinary tract infection
C. Acute ischemic stroke
D. Medication nonadherence
