Answer to Question 1

ANS: C
Memantine blocks the NMDA channels and is used in moderate-to-late stages of the disease. Donepezil, rivastigmine, and galantamine are all cholinesterase inhibitors. These drugs increase the availability of acetylcholine and are most often used to treat mild-to-moderate Alzheimer's disease.

Answer to Question 2

ANS: A
The problems are all aspects of the pathophysiologic characteristics of Alzheimer's disease.
