A nurse is teaching about sources of psychological stress to a group of newly licensed nurses. The nurse should identify which of the following qualifies as a source of psychological distress?

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.

A. Psychiatrist: Psychiatrists focus primarily on medical and pharmacological interventions for mental illnesses. While they play a crucial role in diagnosing and treating mental health conditions, they typically do not have the expertise in housing assistance or social services.

B. Behavioral therapist: Behavioral therapists focus on psychotherapeutic interventions to address and modify behavior. They are not typically involved in addressing social determinants of health, such as housing.

C. Social worker: Social workers are specifically trained to address social issues, including housing. They work with clients to assess their social needs, connect them with resources, and advocate for their well-being. In this case, a social worker would be instrumental in helping the client find housing resources and support.

D. Psychologist: Psychologists primarily focus on psychological assessments, therapy, and interventions. Like psychiatrists, their expertise is more centered around mental health treatment rather than addressing the social determinants of health such as housing.
