Q1. The major impact of the physiological changes that occur with aging is best
described as which of the following? A. Reduced physiological reserve
B. Reduced homeostatic mechanisms
C. Impaired immunological response
D. All of the above
Correct Answer: D
Rationale: Multiple organ systems undergo age-related changes that collectively lead to
diminished homeostasis, decreased reserve capacity, and less robust immune responses.
Q2. The strongest evidence regarding normal physiological aging is available through
which type of study?
A. Randomized controlled clinical trials
B. Cross-sectional studies
C. Longitudinal studies
, Page 2 of 94
D. Case-control studies
Correct Answer: C
Rationale: Longitudinal studies, which follow the same individuals over time, provide the
most valid insights into age-related physiological change.
Q3. All of the following statements about laboratory values in older adults are true
EXCEPT:
A. Reference ranges are preferable.
B. Abnormal findings are often due to physiological aging.
C. Normal ranges may not be applicable for older adults.
D. Reference values are not necessarily acceptable values.
Correct Answer: B
Rationale: Not all abnormal laboratory findings can be automatically attributed to “just
aging.” Clinicians must investigate abnormalities rather than dismiss them as normal aging.
Q4. Biochemical individuality is best described as which of the following? A. Each
individual’s variation is often much greater than that of a larger group.
B. The unique biochemical profile of a selected population.
C. The truly “normal” individual falling within the average range.
D. Each individual’s variation is often much smaller than that of a larger group.
Correct Answer: D
Rationale: Biochemical individuality refers to the concept that an individual’s variation is
often much smaller than the variation seen across a larger group, meaning population-based
reference ranges may not reflect an individual’s normal.

Q5. Which of the following is an expected age-related change in the cardiovascular
system?
A. Increased resting heart rate
B. Decreased arterial compliance
C. Increased cardiac output
D. Decreased systolic blood pressure
Correct Answer: B
Rationale: Aging is associated with decreased arterial compliance (stiffening of the arteries),
which contributes to increased systolic blood pressure and reduced cardiovascular reserve.
Q6. Which of the following is an expected age-related change in the renal system?
A. Increased glomerular filtration rate
B. Decreased renal blood flow
C. Increased bladder capacity
D. Increased urine concentration ability
Correct Answer: B
Rationale: Renal blood flow and glomerular filtration rate decline with age, reducing the
kidney’s ability to concentrate urine and excrete drugs.
Q7. Which of the following is an expected age-related change in the pulmonary system?
A. Increased chest wall compliance
B. Decreased residual volume
C. Decreased vital capacity
D. Increased gas exchange efficiency
Correct Answer: C
, Page 4 of 94
Rationale: Age-related changes in the chest wall and lung parenchyma lead to decreased
vital capacity and increased residual volume.
Q8. Which of the following is an expected age-related change in the gastrointestinal
system?
A. Increased gastric acid secretion
B. Decreased intestinal motility
C. Increased liver size
D. Increased esophageal sphincter tone
Correct Answer: B
Rationale: Decreased intestinal motility and delayed gastric emptying are common
agerelated changes that can contribute to constipation.
Q9. Which of the following is an expected age-related change in the immune system?
A. Increased T-cell function
B. Decreased antibody response to new antigens
C. Increased inflammatory response
D. Increased natural killer cell activity
Correct Answer: B
Rationale: Immunosenescence involves a decreased ability to mount an antibody response
to new antigens, increasing susceptibility to infections.
Q10. Which of the following is an expected age-related change in the nervous system?
A. Increased reaction time
B. Increased brain weight
C. Increased neurotransmitter production
