What is the leading cause of disability in old age?
Arthritis
Urinary tract infection
Macular degeneration
Pressure ulcers
The Correct Answer is A
A. Arthritis
Arthritis, especially osteoarthritis, is the most common cause of functional limitation and disability among older adults.
B. Urinary tract infection
While common in the elderly, UTIs are typically acute conditions and not a leading cause of long-term disability.
C. Macular degeneration
Though this affects vision and can cause impairment, it is less common than arthritis and does not affect mobility.
D. Pressure ulcers
These result from immobility, rather than causing it, and are more of a complication than a primary cause of disability.

A. Changes in the lens
Related to vision changes (e.g., presbyopia), not hearing.
B. Hardening of the outer ear canal
Can cause conductive hearing loss, but presbycusis is sensorineural in nature.
C. Atrophic changes in the cochlea
Presbycusis is due to degeneration of the cochlea and auditory nerve, a normal age-related change.
D. Ototoxicity from medications
This causes pathologic hearing loss, not the gradual, age-related loss seen in presbycusis.
Correct Answer is C
Explanation
A. Wrinkles
Caused by loss of collagen and elasticity, not directly by oil loss.
B. Brown spots
Caused by sun exposure and aging, unrelated to skin oil content.
C. Itching
