Answer to Question 1

A

Feedback
A Correct. This is not a common age-related physical change. A small number of taste buds are lost beginning around age 60, and it does not affect all flavors equally.
B Incorrect. This is a common change and can affect ease of swallowing.
C Incorrect. This is a common change and can affect the sense of satiety.
D Incorrect. This is a common change and can contribute to early satiety.

Answer to Question 2

C
Confirming the development of neurofibrillary tangles is the only accurate method for diagnosing AD. Patients with AD can be observed for dementia and delirium, but these indicators are nonspecific for the disease. The inability to speak with relevance is a feature of dementia; if other causes of dementia are ruled out, then it may be dementia of the Alzheimer type. A CAT scan is the most useful means for diagnosing a stroke.
