Answer to Question 1

B
Tacrine, donepezil, rivastigmine, and galantamine act by increasing the brain's supply of
acetylcholine, a neurotransmitter deficient in people with Alzheimer's disease. These drugs improve
functioning and slow the progress of the disease in 20 to 50 of clients. They do not provide a
cure. Memantine affects N-methyl-D-aspartate receptors and has also been shown to provide
significant benefits when administered with donepezil. Options 1 and 3: Medications affecting
dopamine action or glutamate receptors are not indicated in treatment of Alzheimer's disease.
Option 4 is untrue.

Answer to Question 2

B
Tolerance refers to needing higher and higher doses of a drug to produce the desired effect. Option
A: The potency of the alcohol is stable. Options C and D: Neither hypomagnesemia nor antagonistic
effects would account for this change.
