Answer to Question 1

B
Although aging is a universal experience, each individual older person represents a different pattern of aging. Response A is not a good answer because it implies that the aging experience of every older person is the same. Responses C and D do not address normal aging. Older adults may experience depression and chronic diseases, but these are not normal aging experiences.

Answer to Question 2

B
Vitamin K functions in blood clotting and in regulating blood calcium and bone development. A deficiency of vitamin K can result in hemorrhaging, a sign of which is very dark and bloody stools. This is most likely to occur in an older person who is taking antibiotics, which destroy the normal intestinal bacteria responsible for extracting vitamin K from food. Lack of vitamin C, phosphorus, or iron in the diet can result in abnormal conditions in different body systems, but vitamin K is most directly linked to blood clotting.
