Answer to Question 1
ANS: C
Medications used to treat psychiatric disorders operate in and around the synaptic cleft and have action at the neurotransmitter level, especially in the case of schizophrenia, on dopa-mine. The Wernicke's area, dendrite function, or the sensitivity of the peripheral nervous system are not relevant to either schizophrenia or psychotropic medications.
Answer to Question 2
ANS: D
Nurses must understand that many symptoms of psychiatric disorders have a neurologic ba-sis, although the symptoms are manifested behaviorally. This understanding facilitates effec-tive care planning. The foundation of knowledge is not used exclusively by advanced prac-tice psychiatric nurses nor is it relevant for only behavior therapies or brain trauma since dealing with the results of normal and abnormal brain function is a responsibility of all nurses providing all types of care to the psychiatric patient.
