Answer to Question 1

B
Olfactory changes begin around age 50 and include a loss of cells in the olfactory bulb of the brain and a decrease in the number of sensory cells in the nasal lining. Reduced sensitivity to odors is common. A small decrease in the number of taste cells occurs with aging, beginning around age 60 . Reduced sour, salty, and bitter taste discrimination is common. The ability to detect sweet tastes seems to remain intact. Xerostomia is the decrease in salivary production that leads to thicker mucus and a dry mouth. This interferes with the ability to eat and leads to appetite and nutritional problems.

Answer to Question 2

B
Visual changes often include reduced visual fields, increased glare sensitivity, impaired night vision, reduced accommodation, reduced depth perception, and reduced color discrimination. Many of these symptoms occur because the pupils in the older adult take longer to dilate and constrict secondary to weaker iris muscles. Color vision decreases because the retina is duller and the lens yellows. Eventually, older adults may require three times as much light to see things as they did when they were in young adulthood.
