Answer to Question 1

ANS: B
Increased acetylcholine plays a role in learning and memory. Preventing destruction of acetylcholine by acetylcholinesteras e would result in higher levels of acetylcholine, with the potential for improved memory. GABA affects anxiety rather than memory. Increased dopamine would cause symptoms associated with schizophrenia or mania rather than improve memory. Decreasing dopamine at receptor sites is associated with Parkinson's disease rather than improving memory.

Answer to Question 2

ANS: B
The parent is seeking information about PET scans. It is important to use terms the parent can understand, so the nurse should identify what the initials mean. The correct response is the only option that provides information relevant to PET scans. The distracters describe MRI, CT scans, and EEG. See relationship to audience response question.
