A withdrawn client diagnosed with schizophrenia expresses little emotion and refuses to attend group therapy.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. WBC count 3,300/mm³.
Clozapine, an atypical antipsychotic medication, is associated with a risk of agranulocytosis, which is a severe reduction in white blood cell (WBC) count. A WBC count of 3,300/mm³ is significantly below the normal range, and it indicates a contraindication to the use of clozapine.
B. Asthma:
Asthma is not a contraindication to clozapine. However, it is important to monitor respiratory function as antipsychotic medications can have side effects related to respiratory function.
C. Hypertension:
Hypertension alone is not a contraindication to clozapine. Clozapine can, however, be associated with some cardiovascular side effects, so blood pressure should be monitored regularly.
D. Fasting blood glucose 120 mg/dL:
An elevated fasting blood glucose level is not a contraindication to clozapine. However, it is important to monitor metabolic parameters as antipsychotic medications, including clozapine, can be associated with metabolic side effects.
Correct Answer is A
Explanation
A. "I can see that you are angry. Let's discuss ways to approach Peter with your concerns."
This response is empathetic and invites the client to discuss their concerns. However, it doesn't explicitly address the client's request for the nurse to take action. The more appropriate approach would involve the nurse taking direct responsibility for addressing the issue.
B. "Why are you overreacting to the issue?"
This response may be perceived as dismissive and judgmental. It does not validate the client's concerns or address the issue constructively.
C. "You should bring this to the attention of your treatment team."
While involving the treatment team is important, the client has directly approached the nurse with a concern. It is appropriate for the nurse to take the initial step in addressing the issue directly rather than immediately redirecting the client to the treatment team.
D. "I'll talk to Peter and present your concerns."
This is the most appropriate response. It acknowledges the client's concerns, takes responsibility for addressing the issue, and ensures that the client's voice is heard. The nurse can discuss the matter with Peter and work towards a resolution.
