A withdrawn client diagnosed with schizophrenia expresses little emotion and refuses to attend group therapy.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 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.
Correct Answer is D
Explanation
A. A client diagnosed with hypomania who is speaking loudly on the unit: Hypomania involves elevated mood and increased activity, but it doesn't typically present an immediate risk of harm to self or others. While it may be disruptive, it doesn't have the same urgency as active suicidal ideation.
B. A client diagnosed with hypomania who is complaining of pain: Pain complaints should be addressed, but in the context of the given choices, it is not the highest priority. Assessing and addressing the potential for harm due to active suicidal ideation is more critical.
C. A client with a history of mania who is pacing in the hallway: Pacing in the hallway, while indicative of increased activity, does not necessarily indicate an immediate risk. The client expressing active suicidal ideations poses a more urgent concern that requires immediate attention.
D.A client diagnosed with mania who expressed active suicidal ideations
In determining priority, the nurse should consider the level of risk and the potential for harm to self or others. Suicidal ideation is a significant concern that requires immediate attention. A client expressing active suicidal thoughts poses an immediate risk to their safety.
