A withdrawn client diagnosed with schizophrenia expresses little emotion and refuses to attend group therapy.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 B
Explanation
A. "I will take Lithobid on an empty stomach": This statement is incorrect. Lithobid is usually taken with meals or right after meals to minimize gastrointestinal side effects. Taking it on an empty stomach may lead to increased side effects.
B. "I will maintain normal salt intake": This statement is correct. Lithium levels in the blood can be influenced by sodium levels. Maintaining a consistent and normal salt intake is important for the proper functioning of lithium in the body. Both low and high sodium levels can affect lithium levels.
C. "I will consume more fluids": This statement is generally correct. Adequate fluid intake is important to prevent dehydration, as lithium is excreted by the kidneys. However, it should be balanced, and excessive fluid intake should be avoided to prevent lithium toxicity.
D. "I will limit my intake of fluids daily": This statement is incorrect. While fluid intake should be monitored and maintained at a reasonable level, restricting fluids too much can lead to dehydration and an increased risk of lithium toxicity.
