A nurse would anticipate that treatment for a patient with memory difficulties might include medications designed to:
a. inhibit gamma-aminobutyric acid (GABA).
b. prevent destruction of acetylcholine.
c. reduce serotonin metabolism.
d. increase dopamine activity.
ANS: B
Increased acetylcholine plays a role in learning and memory. Preventing destruction of acetylcholine by acetylcholinesterase 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.
