Answer to Question 1

Ans: A
Persons with Lewy body dementia are at risk for visual hallucinations. Low vision is 20/70 visual acuity to 20/200 visual acuity. Visual acuity will not improve with dementia medications, as anticholinergics also impair vision. Cataracts are unrelated to Lewy body dementia, although they are common in all older adults.

Answer to Question 2

Ans: B
Studies suggest that central auditory structures (e.g., primary auditory cortex and auditory brainstem) account for a significant component of hearing loss in older adults, particularly with regard to speech perception. The external ear changes that occur with normal aging are not directly related to hearing loss (including hair growth in men). The tympanic membrane thins and stiffens with age.
