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 cholinesterace 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: B
Careful observation and supervision are of ultimate importance because an appropriate outcome would be that the patient will remain safe and free from injury. Physical contact during care cannot be avoided. Activating a bed alarm is only one aspect of providing for the patient's safety.
