A high school senior is diagnosed with anorexia nervosa and is hospitalized for severe malnutrition. The treatment team is planning to use behavior modification. What rationale should a nurse identify as the reasoning behind this therapy choice?

This therapy will increase the clients motivation to gain weight

This therapy will provide the client with control over behavioral choices

This therapy will reward the client for perfectionist achievement

This therapy will protect the client from parental overindulgence

Answer and Explanation

The Correct Answer is B

A. "This therapy will increase the client's motivation to gain weight": Behavior modification focuses on changing specific behaviors through reinforcement or consequences. While motivation may be a component, the primary goal of behavior modification is to address and modify specific behaviors, such as eating habits, rather than solely relying on motivation.

B. "This therapy will provide the client with control over behavioral choices": Anorexia nervosa often involves issues of control, and behavior modification can empower the individual to regain control over their eating behaviors in a structured and supportive manner. It involves setting goals, reinforcing positive behaviors, and providing a sense of control within the therapeutic framework.

C. "This therapy will reward the client for perfectionist achievement": While anorexia nervosa is associated with perfectionism, rewarding for perfectionist achievement may inadvertently reinforce unhealthy behaviors. Behavior modification aims to promote positive behaviors related to health and well-being rather than reinforcing perfectionism.

D. "This therapy will protect the client from parental overindulgence": Behavior modification is not primarily focused on protecting the client from external factors like parental overindulgence. Instead, it aims to modify specific behaviors through positive reinforcement or consequences.

Correct Answer is B

Explanation

A. fluoxetine (Prozac):

Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) commonly used to treat depression and anxiety disorders. While SSRIs can have side effects, significant alterations in cardiac or cerebral electrical conductivity and fluid/electrolyte imbalance are not typically associated with fluoxetine. The primary concerns with SSRIs are related to serotonin levels and can include gastrointestinal disturbances, insomnia, and sexual dysfunction.

B. Lithium (Lithobid):

This is the correct answer. Lithium is known to have potential side effects related to cardiac and cerebral function, as well as fluid and electrolyte balance. Monitoring blood levels of lithium is crucial to avoid toxicity, which can affect the cardiovascular and central nervous systems. Lithium toxicity can lead to symptoms such as tremors, confusion, ataxia, and, in severe cases, seizures.

C. venlafaxine (Effexor):

Venlafaxine is a serotonin-norepinephrine reuptake inhibitor (SNRI) commonly used to treat depression and anxiety disorders. While it can cause some cardiovascular effects, the concern for significant alterations in cardiac or cerebral electrical conductivity and fluid/electrolyte imbalance is generally lower compared to lithium. The primary side effects of venlafaxine are related to serotonin and norepinephrine levels and may include increased blood pressure and heart rate.

D. clozapine (Clozaril):

Clozapine is an atypical antipsychotic medication used to treat schizophrenia. While antipsychotics can have side effects related to metabolic changes, significant alterations in cardiac or electrolyte imbalances are not typically associated with clozapine as the primary concern. Regular monitoring for metabolic side effects, such as weight gain and changes in lipid and glucose levels, is important with antipsychotic medications.

A. Axons B. Neurotransmitters C. Dendrites D. Synapses

Correct Answer is B

Explanation

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.
