Answer to Question 1

ANS: D
Increased acetylcholine plays a role in learning and memory. Preventing the destruction of acetylcholine by acetylcholinesteras e results in higher levels of acetylcholine with the potential for improved memory. GABA is known to affect anxiety level rather than memory. Increased dopamine causes symptoms associated with schizophrenia or mania rather than improves memory. Decreasing dopamine at receptor sites is associated with Parkinson disease rather than improving memory.

Answer to Question 2

ANS: B
A CT scan and an MRI visualize neoplasms and other structural abnormalities. A PET scan, SPECT scan, and fMRI, which give information about brain function, are not indicated. An arteriogram would not be appropriate.
