Section 1: Foundations of Frailty & Aging
Questions 1-20 · 20 questions
*Q1:* Which statement best characterizes the concept of frailty as defined in advanced
practice gerontological nursing?
A. An inevitable consequence of advanced chronological age in which all organ systems
decline at the same rate
B. A single-organ diagnosis confirmed by imaging evidence of sarcopenia and
osteoporosis
C. A state of increased vulnerability to stressors resulting from decreased physiological
reserves and dysregulation across multiple systems *[CORRECT]*
D. A psychiatric condition characterized by loss of motivation and social withdrawal in
older adults
Correct Answer: C
Rationale: NURS 6540 teaches that frailty is a multidimensional geriatric syndrome of diminished
physiological reserve and increased vulnerability to adverse outcomes from minor stressors, not a normal or
uniform feature of aging (A), a single-organ diagnosis (B), or a psychiatric disorder (D). Recognizing frailty
as a syndrome permits screening, prevention, and targeted intervention consistent with Advanced Practice
Gerontological Nursing Competencies and the AACN Essentials emphasis on health promotion with older
adults.
*Q2:* Which finding is NOT one of the five criteria in the Fried frailty phenotype?
A. Body mass index greater than 30 kg/m2 without weight loss *[CORRECT]*
B. Self-reported exhaustion
C. Slow gait speed adjusted for sex and height
D. Unintentional weight loss
Correct Answer: A
Rationale: The five Fried phenotype criteria are unintentional weight loss (10 lb or more in the past year),
self-reported exhaustion, weak grip strength, slow gait speed, and low physical activity; a BMI above 30
without weight loss is not a criterion (A). Three or more positive criteria classify a patient as frail, one or two
as pre-frail, per the NURS 6540 frailty framework. Distractors B, C, and D are actual phenotype components
and represent common assessment errors when they are omitted from screening.

*Q3:* An 84-year-old woman reports losing 12 pounds in the past year without dieting, feels
exhausted most days, needs 30 seconds to rise from a chair five times, walks slowly, and has
stopped attending her weekly card game and church services. Which classification applies
using the Fried criteria?
A. Robust, because she remains community dwelling
B. Pre-frail, because fewer than three criteria are present
C. Non-frail, because exhaustion is a symptom of depression rather than frailty
D. Frail, because she meets at least three phenotype criteria *[CORRECT]*
Correct Answer: D
Rationale: This patient demonstrates weight loss, exhaustion, weakness (prolonged chair stands), slow gait,
and low activity, meeting the threshold of three or more Fried criteria for frailty. Dismissing findings as
normal aging (A) or attributing them solely to depression (C) are common management missteps that delay
intervention. Identifying pre-frailty (B) underestimates her risk and misses the opportunity for strength
training, nutritional optimization, and comprehensive assessment emphasized in NURS 6540.
*Q4:* A clinician uses the Rockwood Frailty Index for a 79-year-old man with 9 deficits
present out of 30 variables assessed. How should the result be interpreted?
A. Frailty Index cannot be calculated without grip strength measurement
B. Frailty Index equals 0.30, indicating frailty because the value exceeds the 0.25
threshold *[CORRECT]*
C. Frailty Index equals 9, indicating mild frailty only
D. Frailty Index equals 0.09, indicating robust health
Correct Answer: B
Rationale: The Frailty Index is the ratio of deficits present to deficits measured (9 divided by 30 = 0.30);
values above 0.25 indicate frailty in the cumulative deficit model taught in NURS 6540. Option A is
incorrect because the index uses health deficits rather than a single physical measure, and option C
misapplies the ratio by reporting the raw count. Option D miscomputes the fraction and would falsely
reassure the team, illustrating the kind of assessment error that changes care planning.
*Q5:* Which mechanism best describes inflammaging in the pathophysiology of frailty?
A. An acute, high-fever inflammatory response to seasonal viral infection
B. Chronic, low-grade systemic elevation of pro-inflammatory cytokines such as IL-6 and
CRP with aging *[CORRECT]*
C. An exaggerated anaphylactic response to medications in older adults
D. Age-related absence of all inflammatory mediators leading to poor wound healing
Correct Answer: B
Rationale: Inflammaging is the chronic, low-grade sterile inflammation of aging marked by elevated IL-6,
TNF-alpha, and CRP, which drives sarcopenia, disability, and frailty as covered in the NURS 6540
biological-aging module. Option A confuses inflammaging with acute infection, option C describes
hypersensitivity, and option D is the opposite of the actual state. Understanding inflammaging links basic
science to clinical findings such as anemia, muscle loss, and slower recovery from illness.

*Q6:* A 76-year-old man has handgrip strength of 24 kg (right and left average) and a usual
gait speed of 0.7 m/s. His BMI is 27. Which condition is most consistent with these findings?
A. Osteoarthritis limited to the hands
B. Normal age-related change requiring no follow-up
C. Peripheral vascular disease
D. Sarcopenia, defined by low muscle strength plus low physical performance
*[CORRECT]*
Correct Answer: D
Rationale: EWGSOP2 criteria for probable sarcopenia include grip strength below 27 kg in men, and low
physical performance such as gait speed at or below 0.8 m/s confirms the diagnosis; this patient meets both
markers. Calling these findings normal aging (B) or attributing them to isolated arthritis (A) reflects common
misconceptions that delay referral to resistance exercise and protein optimization central to NURS 6540
management. Peripheral vascular disease (C) does not explain the combined strength and gait pattern.
*Q7:* Immunosenescence contributes to which clinical pattern commonly encountered in frail
elders?
A. Blunted antibody response to influenza vaccine with higher breakthrough infection risk
*[CORRECT]*
B. Heightened cutaneous delayed-type hypersensitivity reactions
C. Increased thymic output of naive T lymphocytes
D. Uniform enhancement of both innate and adaptive immunity
Correct Answer: A
Rationale: Immunosenescence involves thymic involution, reduced naive T-cell output, and impaired
adaptive responses, producing weaker vaccine responses and greater infection susceptibility, as taught in the
NURS 6540 aging physiology unit. Option C reverses the actual thymic change, while options B and D
contradict the global decline in immune competence. This knowledge supports practice changes such as
high-dose influenza vaccine and adjuvanted vaccines for older adults under AACN-aligned evidence-based
care.
