Q1 Question 1 of 50
A 72-year-old male patient presents for his annual wellness visit. He reports that over the
past year he has noticed a gradual decline in his ability to read fine print and has increased
difficulty driving at night. On physical examination, his near vision is reduced and he has
some yellowing of the lens. Which age-related change best explains these findings?
D. Macular degeneration affecting central visual acuity
A. Decreased tear production leading to dry eye syndrome
B. Presbyopia from loss of lens elasticity and accommodation
C. Cataract formation causing complete opacification of the lens
Correct Answer: A
Rationale:
Presbyopia results from age-related loss of lens elasticity and decreased ciliary muscle tone, reducing
the eye's ability to accommodate for near vision. The gradual onset of difficulty with reading and night
driving in a 72-year-old is classic for presbyopia. While cataracts (C) cause lens opacification, they
typically produce glare and progressive visual blurring rather than isolated near-vision difficulty. Dry
eye (A) causes irritation but not near-vision loss, and macular degeneration (D) primarily affects
central vision acuity, not accommodation.

Q2 Question 2 of 50
A 68-year-old woman is being evaluated for frequent falls. Her gait analysis reveals a
shortened stride length, decreased step height, and a slightly widened base of support.
She denies pain or weakness in her extremities. Which age-related musculoskeletal
change is the most likely underlying cause of these gait alterations?
A. Osteoporosis-related vertebral compression fractures
B. Age-related sarcopenia and loss of fast-twitch muscle fibers
C. Degenerative joint disease of the hips and knees
D. Peripheral neuropathy affecting proprioception
Correct Answer: B
Rationale:
Sarcopenia, the age-related loss of muscle mass and strength, particularly affects type II fast-twitch
fibers responsible for power and rapid movement. This leads to shortened stride length, decreased
step height, and compensatory gait changes in older adults. Osteoporosis (A) and degenerative joint
disease (C) would typically present with pain, which the patient denies. Peripheral neuropathy (D)
would cause sensory deficits and ataxia, not specifically the gait pattern described.

Q3 Question 3 of 50
During a routine hearing assessment, a 75-year-old man is found to have bilateral
high-frequency hearing loss that is symmetric and gradual in onset. He reports difficulty
understanding conversations in noisy environments. Which type of age-related hearing
loss is most consistent with this presentation?
B. Presbycusis affecting the cochlear hair cells
C. Sensorineural loss from acoustic neuroma
D. Mixed hearing loss from chronic otitis media
A. Conductive hearing loss from otosclerosis
Correct Answer: C
Rationale:
Presbycusis is the most common age-related hearing loss, characterized by bilateral, symmetric,
high-frequency sensorineural hearing loss due to degeneration of cochlear hair cells and the stria
vascularis. The difficulty with speech discrimination in noisy environments is classic. Otosclerosis (A)
typically causes conductive loss in younger adults, acoustic neuroma (C) presents with asymmetric
unilateral loss and tinnitus, and chronic otitis media (D) would show a history of ear infections and
possible conductive component.
