A withdrawn client diagnosed with schizophrenia expresses little emotion and refuses to attend group therapy.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. To emphasize that the client is capable of consuming food without purging: This is the correct purpose of the intervention. By recalling a time when the client was able to consume food without engaging in purging behaviors, the nurse aims to highlight the client's capability to eat without resorting to unhealthy practices.
B. To incorporate specific foods into the meal plan to reflect pleasant memories: While incorporating pleasant memories into the meal plan can be a positive aspect of treatment, the primary purpose of the intervention described is to focus on the client's ability to eat without purging.
C. To assist the client to become more compliant with the treatment plan: While promoting compliance with the treatment plan is important, the specific intervention described is more about exploring the client's past experiences with eating without purging to reinforce the possibility of achieving healthier eating habits.
D. To gain additional information about the progression of the disease process: The intervention is not primarily aimed at gaining information about the progression of the disease process. Instead, it is focused on emphasizing the client's capacity to eat without engaging in purging behaviors.
Correct Answer is A
Explanation
Orientation: When a nurse asks a client to identify their name, date, residential address, and situation, they are assessing the client's orientation. Orientation refers to an individual's awareness of time, place, person, and situation.
B. Affect: Affect refers to the observable expression of emotions. It involves the client's emotional tone, such as being happy, sad, angry, or flat. It is not directly assessed by asking about personal information.
C. Perception: Perception involves the way individuals interpret and make sense of sensory information. Asking about personal information is more related to orientation than perception.
D. Mood: Mood refers to a more sustained emotional state. It is not directly assessed by asking for specific personal information about the current situation or location.
