A withdrawn client diagnosed with schizophrenia expresses little emotion and refuses to attend group therapy.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. The voices are telling me to harm myself: This statement indicates command hallucinations with a potential for harm. It suggests that the patient is receiving directives to harm themselves, which poses an immediate safety concern. Implementing safety measures, such as close monitoring, removal of harmful objects, and involving appropriate professionals, is essential to protect the patient from self-harm.
B. I hear voices: While hearing voices (auditory hallucinations) is a symptom that requires assessment and intervention, the nature of the voices is crucial in determining the level of risk. This statement, on its own, does not provide information about the content or potential harm associated with the voices.
C. I see birds flying in the room: This statement describes a visual hallucination, which, while potentially distressing, does not necessarily pose an immediate safety risk to the patient or others. Visual hallucinations may be less likely to necessitate immediate safety measures compared to command hallucinations.
D. The voices don't stop and continue all day: This statement suggests persistent auditory hallucinations, but without information about the content of the voices, it does not specifically indicate a risk of harm. While it may be distressing for the patient, the urgency for safety measures depends on the nature of the auditory content.
Correct Answer is A
Explanation
A. Your child has a chemical imbalance of the brain, which leads to altered thoughts: This is the correct answer. It acknowledges the role of a chemical imbalance in the brain contributing to altered thoughts and hallucinations in the context of schizophrenia.
B. Your child's hallucinations are caused by medication interactions: This explanation is not likely in this context. While medications can have side effects, command hallucinations in schizophrenia are primarily related to the underlying disorder.
C. Your child has too little serotonin in the brain causing delusions and hallucinations: While serotonin is involved in mood regulation, attributing hallucinations solely to low serotonin levels oversimplifies the complex neurobiology of schizophrenia.
D. Your child's abnormal hormonal changes have precipitated auditory hallucinations: Hormonal changes are not considered a primary cause of auditory hallucinations in schizophrenia. The emphasis is on neurobiological and genetic factors influencing brain function.
