The shift nurse brings ailing eighty-year-old Gertrude her dinner. As Gertrude eats a small amount of her food, she comments that she isn't hungry and that “hospital food just doesn't taste good!” The nurse gives Gertrude a menu so she can choose her morning breakfast. Gertrude complains that she is having trouble reading the menu and asks the nurse to read it to her. As the nurse begins to read, Gertrude loudly asks her to “speak up and turn off the buzzing.” What does the nurse know about aging and the special senses that help to explain Gertrude's comments?

- You are watching the stars at night, and you never seem to be looking at the right spot to catch the brightest meteors. Which of the following might explain this? a)Your fovea contains mostly cones; thus you see dim light especially well when looking right at it. b)Your peripheral retina contains more rods, which are more sensitive to dim light than cones; thus objects in your peripheral vision appear brighter in dim light situations. c)Detection of light depends mostly on its color rather than intensity; thus cones play a larger role in detection of light in dim light situations. d) all of the above. ( well explain the correct answer and type answer).arrow_forwardGeorge was under a lot of stress. His final semester examination was only 2 days away, and he was not prepared at all.

Since the disease affects the inner ear, it would probably cause nausea and migraines. Since the disease affects the inner ear, it would probably cause issues with taste. Since the disease affects the inner ear, it would probably cause issues with balance and a sensation of vertigo. It could also cause hearing loss if it affected the cochlea.arrow_forward
