A withdrawn client diagnosed with schizophrenia expresses little emotion and refuses to attend group therapy.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

Answer and Explanation

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 B

Explanation

A. Hypotensive shock: This is not the correct answer. MAO inhibitors are not associated with causing hypotensive shock. In fact, they can lead to an increase in blood pressure.

B. Hypertensive crisis: This is the correct answer. MAO inhibitors interact with certain foods and drugs, such as those containing tyramine, leading to an increased risk of a hypertensive crisis. Foods rich in tyramine, such as aged cheeses, certain wines, and some processed meats, can cause a sudden and dangerous increase in blood pressure when combined with MAO inhibitors.

C. Cardiac dysrhythmia: While all medications have potential side effects, MAO inhibitors are not typically associated with causing cardiac dysrhythmias.

D. Cardiogenic shock: MAO inhibitors are not known to cause cardiogenic shock. The primary concern with MAO inhibitors is the potential for a hypertensive crisis due to interactions with specific foods and drugs.

A. Limit time for the client to perform activities B. Rotate assignment of daily caregivers. C. Provide an activity schedule that changes from day to day. D. Talk the client through tasks one step at a time

Correct Answer is D

Explanation

A. Limit time for the client to perform activities:

This option may increase agitation and frustration for the client with Alzheimer's disease. It is generally not recommended to limit their time for activities, as it may lead to distress.

B. Rotate assignment of daily caregivers:

Consistency in caregivers is often beneficial for individuals with Alzheimer's disease. Constantly changing caregivers can lead to confusion and anxiety for the client. Thus, rotating caregivers is not the best approach.

C. Provide an activity schedule that changes from day to day:

Individuals with Alzheimer's disease often benefit from routine and predictability. Changing the activity schedule daily can cause confusion and disorientation. Therefore, it is not the most appropriate intervention.

D. Talk the client through tasks one step at a time:

This is the best choice because breaking down tasks into simple, manageable steps can help individuals with Alzheimer's disease understand and follow instructions. It promotes a sense of accomplishment and reduces frustration. This approach is aligned with the principles of dementia care.
