- A. Alopecia
- B. Yellowish skin tone

An 80-year-old patient is brought to the clinic by her son. The son asks the nurse why his mother has gotten so many spots on her skin. What would be an appropriate response by the nurse?
- A. As people age, they normally develop uneven pigmentation in their skin.
- B. These spots are called liver spots or age spots.
- C. Older skin is more apt to break down and tear, causing sores.
- D. These are usually the result of nutritional deficits earlier in life.

- B. Has she bathed in the past 24 hours?
- C. Did she go to a friends house today?
