SECTION 1: Foundations of Frailty & Aging
Q1: An 82-year-old woman presents to the clinic with her daughter, who reports her mother has lost 12 lb
unintentionally over the past year, feels 'exhausted most days,' and has stopped attending her weekly
senior center program. Grip strength is reduced and gait speed is 0.6 m/s. Applying Fried's frailty
phenotype, how many of the five criteria must be present to classify this patient as frail?
A. One criterion identifies frailty; two or more indicate pre-frailty only
B. Three or more of the five criteria confirm frailty *[CORRECT]*
C. All five criteria must be present to diagnose frailty
D. Two criteria are sufficient if weight loss exceeds 10% of body weight
Correct Answer: B
Rationale: Fried's phenotype defines frailty as the presence of three or more of five criteria: unintentional weight loss (≥10
lb/year), self-reported exhaustion, weakness (grip strength), slow gait speed, and low physical activity. One to two criteria
indicate pre-frailty, while zero indicates robustness. This patient meets all five, confirming frailty and signaling elevated risk
for adverse outcomes such as falls, disability, and mortality.
Q2: A 78-year-old man has a cumulative deficit frailty index of 0.35 calculated from 40 health variables.
Which interpretation best reflects the implications of this score according to Rockwood's deficit
accumulation model?
A. The score indicates robust health; no intervention is needed
B. A frailty index of 0.35 indicates moderate frailty with elevated risk of adverse outcomes *[CORRECT]*
C. A score above 0.25 always reflects terminal illness
D. The frailty index only applies to community-dwelling elders without cognitive impairment
Correct Answer: B
Rationale: Rockwood's frailty index expresses frailty as a ratio of accumulated deficits to total variables assessed. Scores
≤0.08 suggest robustness, 0.08–0.25 indicate pre-frailty, and >0.25 denote frailty. A score of 0.35 indicates
moderate-to-severe frailty, predicting increased risk of falls, hospitalization, institutionalization, and mortality. Unlike the
Fried phenotype, the deficit model captures multi-system vulnerability and is well validated across settings including
cognitively impaired populations.

Q3: A 75-year-old patient asks the nurse practitioner why she feels tired and weaker than she did 10 years
ago despite having no specific disease. The NP explains the concept of 'inflammaging.' Which mechanism
best describes inflammaging?
A. Acute inflammatory response to infection that resolves within days
B. Chronic, low-grade systemic inflammation that develops with aging and contributes to sarcopenia and
frailty *[CORRECT]*
C. Autoimmune reaction triggered by recent vaccination
D. Allergic response to environmental antigens accumulated over decades
Correct Answer: B
Rationale: Inflammaging refers to the chronic, low-grade, systemic inflammatory state that accompanies aging,
characterized by elevated IL-6, TNF-α, and CRP. It contributes to sarcopenia, immune dysregulation, neurodegeneration, and
atherosclerosis, and is a central mechanism linking aging to frailty. NURS 6540 emphasizes inflammaging as a target for
comprehensive assessment, because it is modifiable through exercise, nutrition, and inflammation-aware prescribing.
Q4: A frail 85-year-old woman is admitted with pneumonia. Compared with a robust peer, her
physiological response is impaired due to 'homeostenosis.' Which statement best defines this concept?
A. Loss of ability to maintain baseline function under stress due to narrowed physiological reserve
*[CORRECT]*
B. Progressive destruction of all organ systems at an equal rate
C. Reversal of normal homeostatic mechanisms into pathological processes
D. Complete loss of all hormonal feedback loops after age 80
Correct Answer: A
Rationale: Homeostenosis describes the age-related narrowing of physiological reserve across multiple organ systems, so that
stressors (infection, surgery, dehydration) produce disproportionate functional decline. The frail elder maintains steady-state
function at rest but cannot mount an adequate response when challenged. NURS 6540 frames homeostenosis as the
physiological basis for frailty and the rationale for proactive, low-threshold intervention during acute illness.
Q5: A daughter asks why her 80-year-old father, who has 'nothing wrong' on labs, falls repeatedly.
Examination reveals reduced muscle mass and strength. Which geriatric syndrome does this best describe,
and what is the underlying pathophysiology?
A. Sarcopenia: age-related loss of skeletal muscle mass, strength, and function driven by protein
dysregulation, neuromuscular decline, and inflammation *[CORRECT]*
B. Cachexia: weight loss due to cytokine-mediated muscle wasting from active malignancy
C. Myasthenia gravis: autoimmune destruction of acetylcholine receptors
D. Frailty secondary to hypothyroidism with myxedema
Correct Answer: A
Rationale: Sarcopenia is the progressive, age-related loss of skeletal muscle mass, strength, and physical performance. Unlike
cachexia (which is disease-driven and inflammatory), sarcopenia results from anabolic resistance, neuromuscular junction
remodeling, mitochondrial dysfunction, and inflammaging. Per the SDOCRC and AGS guidelines, it is a cornerstone of
frailty and a primary target for resistance exercise and protein optimization in NURS 6540 practice.

Q6: An 88-year-old man receives the influenza vaccine but develops a prolonged, severe infection despite
vaccination. Which age-related change in immune function best explains this attenuated response?
A. Immunosenescence: progressive decline in immune competence including thymic involution, reduced
naive T-cell production, and blunted vaccine response *[CORRECT]*
B. Immediate hypersensitivity reaction to vaccine preservatives
C. Acquired immunodeficiency from malnutrition alone
D. Anaphylaxis to egg protein in the vaccine
Correct Answer: A
Rationale: Immunosenescence describes the age-related remodeling and decline of the immune system, including thymic
involution, reduced naive T-cell output, accumulation of memory cells, and blunted antibody response to vaccination. This
explains why older adults remain vulnerable despite immunization and why high-dose, adjuvanted, or sequential vaccination
strategies are recommended for frail elders in NURS 6540 practice.
Q7: A nurse practitioner is teaching a community group about 'compression of morbidity.' Which
statement best reflects this concept?
A. Chronic disease is inevitable and disability should be accepted as part of aging
B. Healthy lifestyle behaviors can delay the onset of chronic disease, shortening the period of disability
before death *[CORRECT]*
C. All chronic disease in late life should be aggressively treated to extend lifespan regardless of quality
D. Compression of morbidity refers to reducing the number of diseases through polypharmacy
Correct Answer: B
Rationale: Compression of morbidity, proposed by James Fries, posits that healthy behaviors (exercise, nutrition, social
engagement, risk factor management) can postpone the onset of chronic disease and disability, thereby shortening the period
of functional decline before death. NURS 6540 frames successful aging around this concept, emphasizing primary and
secondary prevention rather than disease-by-disease management.
Q8: Which of the following is the best example of a 'geriatric giant' as classically described by Bernard
Isaacs?
A. Impaired vision requiring cataract surgery
B. Instability (falls) leading to injury and loss of independence *[CORRECT]*
C. Mild hypertension controlled with one medication
D. Localized osteoarthritis of the right knee
Correct Answer: B
Rationale: The 'geriatric giants' (Isaacs) are the major syndromes of impaired mobility and stability in older adults:
instability (falls), immobility, incontinence, intellectual impairment, iatrogenic disease, and impaired homeostasis. These
syndromes share multifactorial etiologies and signal functional decline rather than single-organ disease. NURS 6540
prioritizes them because they drive loss of independence and are often preventable through comprehensive geriatric
assessment.

Q9: An 80-year-old woman has a chronological age of 80 but a biological age estimated at 88 based on
multi-system biomarkers (grip strength, gait speed, inflammatory markers, cognition). Which statement
best captures the clinical implication?
A. Biological age is purely a research concept with no clinical use
B. Biological age may better predict adverse outcomes and should inform individualized goals of care and
treatment intensity *[CORRECT]*
C. Chronological age always supersedes biological age in clinical decisions
D. Biological age is calculated only from chronological age plus weight
Correct Answer: B
Rationale: Biological age reflects physiological reserve and accumulated damage across multiple systems, often diverging
from chronological age. Frailty indices, gait speed, and multi-biomarker panels provide surrogate measures that predict
mortality, disability, and treatment-related adverse events more accurately than chronological age. NURS 6540 promotes
biological age thinking to individualize prevention, treatment intensity, and goals of care conversations.
Q10: A 79-year-old patient asks the NP why he urinates more at night and feels lightheaded when standing
quickly. Which age-related cardiovascular changes best explain these symptoms?
A. Decreased baroreceptor sensitivity and reduced left ventricular compliance leading to orthostatic
hypotension and nocturnal diuresis *[CORRECT]*
B. Increased sympathetic tone causing sustained hypertension throughout the day
C. Improved diastolic filling from enhanced beta-receptor responsiveness
D. Higher cardiac output at rest due to increased stroke volume
Correct Answer: A
Rationale: Aging is associated with reduced baroreceptor sensitivity (blunted heart rate response to position change),
decreased left ventricular compliance (diastolic dysfunction), and increased arterial stiffness. Together these produce
orthostatic hypotension, exertional intolerance, and redistribution of renal perfusion that worsens nocturia. NURS 6540
emphasizes these changes when prescribing antihypertensives, diuretics, and sedatives in frail elders.
Q11: An 82-year-old man recovering from hip fracture surgery develops atelectasis and pneumonia.
Which age-related respiratory change most contributes to this complication?
A. Increased chest wall compliance leading to hyperventilation
B. Decreased chest wall compliance, reduced elastic recoil, and diminished cough reflex leading to
impaired secretion clearance *[CORRECT]*
C. Increased vital capacity from improved respiratory muscle strength
D. Enhanced mucociliary clearance compensating for reduced lung capacity
Correct Answer: B
Rationale: Aging reduces chest wall compliance (costal cartilage calcification), decreases respiratory muscle strength, blunts
cough reflex, and diminishes mucociliary clearance. Combined with reduced vital capacity and reduced ventilatory response
to hypoxia/hypercapnia, frail elders are predisposed to atelectasis and pneumonia after surgery or illness. NURS 6540
prioritizes early mobilization, incentive spirometry, and aspiration precautions in this population.
