Answer to Question 1

ANS: C
Mood changes throughout the day are related to circadian rhythms. Questions about sleep pattern would also be relevant to circadian rhythms. The question about seeing or hearing things is relevant to the assessment for illusions and hallucinations. The question about thinking is relevant to the assessment of thought processes. The other question is relevant to assessment of memory.

Answer to Question 2

ANS: A
Increased levels of GABA reduce anxiety, thus any potentiation of GABA action should result in anxiety reduction. Memory enhancement is associated with acetylcholine and substance P. Thought disorganization is associated with dopamine. GABA is not associated with sensory perceptual alterations.
