B. retain and recall past experience.
C. regulate social behavior.
D. maintain homeostasis.

5.

D. basal ganglia

13.
Based on current understanding of neurotransmitters, the nurse can view a client's symptoms of profound depression as at least partially related to
A. increased dopamine level.
B. decreased serotonin level.
C. increased norepinephrine level.
D. decreased acetylcholine level.

14.
A nursing assistant is speaking to the nurse about a client with schizophrenia. "This guy's mind is gone. Nobody can talk with him. He doesn't make any more sense than someone with Alzheimer's." The nurse can use knowledge of the biological basis of mental illness to facilitate appropriate interaction between the nursing assistant and the client by offering:
A. "Try talking to him early in the day, to get the best results. Fatigue disorganizes his thinking."
B. "Schizophrenia and Alzheimer's disease both cause irreversible brain damage, so keep your conversations short when you talk to a client with either disorder."
C. "His medication targets his disturbed thought and speech patterns. To maximize improvement he'll need positive interactions and support."
D."Make sure he eats the 'comfort foods' he's served, as they increase serotonin production and will help normalize his thoughts and speech."

B. decreased pain
C. improved memory
D. reduced aggression

19.
The physician tells a client who demonstrates use of many rituals, "We want to do an imaging study that will tell us which parts of your brain are particularly active.
