A withdrawn client diagnosed with schizophrenia expresses little emotion and refuses to attend group therapy. What altered component of the nervous system should a nurse recognize as being implicated in this behavior?
Axons
Neurotransmitters
Dendrites
Synapses
The Correct Answer is B
A. Axons: Axons are nerve cell processes that transmit signals away from the cell body. While axons are essential for communication between nerve cells, their structure or function is not directly implicated in the altered behavior associated with schizophrenia.
B. Neurotransmitters: This is the correct answer. In schizophrenia, there is evidence of dysregulation in neurotransmitter systems, particularly dopamine. Dopamine dysregulation is associated with both positive and negative symptoms of schizophrenia. In the case of negative symptoms, such as social withdrawal and reduced emotional expression, hypoactivity in dopamine pathways may play a role.
C. Dendrites: Dendrites are nerve cell processes that receive signals from other neurons. Similar to axons, dendrites are crucial for communication between nerve cells, but their structure or function is not specifically implicated in the altered behavior associated with schizophrenia.
D. Synapses: Synapses are the junctions between nerve cells where neurotransmitters are released to transmit signals. While synapses play a critical role in neurotransmission, the altered behavior in schizophrenia is more closely linked to the dysregulation of neurotransmitters, particularly dopamine, than to structural changes in synapses.

Correct Answer is A
Explanation
A. Provide personal space to respect the client's boundaries: This is the correct answer. Personal space is crucial when caring for an agitated client with paranoia. Respecting the client's need for distance helps to reduce anxiety and prevent escalation of agitation.
B. Maintain continual eye contact throughout the interview: Continuous eye contact may be perceived as confrontational and can increase anxiety, especially in individuals with paranoia. It is important to be mindful of non-verbal cues and adapt the approach to the client's comfort level.
C. Provide neon lights and soft music: Introducing external stimuli like neon lights and music may not be appropriate for an agitated client with paranoia. It could potentially exacerbate their distress. The focus should be on creating a calm and non-threatening environment.
D. Use therapeutic touch to increase trust and rapport: While therapeutic touch can be beneficial in certain situations, it may not be suitable for a client experiencing paranoia. Touch can be perceived as intrusive and may escalate agitation in this context.
Correct Answer is D
Explanation
A. Concern for others: Individuals with antisocial personality disorder typically lack genuine concern for others and may exploit or manipulate them for personal gain.
B. Actively engaged in all unit activities: While engagement in activities can vary, the key feature of antisocial personality disorder is not a high level of engagement but rather a disregard for rules and the rights of others.
C. Mindful of following all of the unit rules: Individuals with antisocial personality disorder often have a history of rule-breaking and may not be consistently mindful of following societal or institutional rules. They may engage in behaviors that violate rules or laws.
D. Manipulative: This is the correct answer. Antisocial personality disorder is characterized by manipulative behaviors, where individuals exploit others for personal gain or pleasure. Manipulation is a key feature of this disorder.
