A nurse is caring for a client who has sleep dysregulation, poor memory, and poor concentration. When collecting data, which of the following neurotransmitters should the nurse identify as being responsible for the client's manifestations?

A. Dialectical behavior therapy. Dialectical behavior therapy is primarily used for borderline personality disorder, focusing on emotional regulation, distress tolerance, and mindfulness. It is not the primary therapy for avoidant personality disorder.
B. Antipsychotic medications. Antipsychotic medications are typically used to manage symptoms of psychotic disorders such as schizophrenia. Avoidant personality disorder does not involve psychosis and is better managed with psychotherapy.
C. Interpersonal therapy. Interpersonal therapy is beneficial for avoidant personality disorder as it focuses on improving social skills, self-esteem, and communication. This therapy helps clients develop healthier relationships and overcome fears of rejection.
D. Antidepressant medications. While antidepressants may be used to treat co-occurring conditions such as depression or anxiety, they do not directly address the core features of avoidant personality disorder. Psychotherapy remains the primary treatment.

A. Lithium toxicity. The AIMS test does not assess lithium toxicity. Lithium toxicity is monitored through serum lithium levels and clinical symptoms such as tremors, nausea, confusion, and ataxia. Severe toxicity can lead to seizures, coma, and organ failure, requiring immediate intervention.
B. Alcohol withdrawal. The AIMS test does not assess alcohol withdrawal. Withdrawal symptoms include tremors, hallucinations, seizures, and autonomic instability. The Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) is commonly used to assess symptom severity and guide treatment.
C. Tardive dyskinesia. The AIMS test is used to assess tardive dyskinesia, a movement disorder caused by long-term antipsychotic use. It evaluates involuntary movements of the face, tongue, and extremities, helping clinicians monitor progression and adjust medications to minimize symptoms.
D. Opiate withdrawal. The AIMS test does not assess opiate withdrawal. Symptoms include sweating, agitation, diarrhea, and muscle aches. The Clinical Opiate Withdrawal Scale (COWS) is typically used to assess withdrawal severity and guide opioid detoxification or replacement therapy.
