A nurse in an emergency department is collecting data from a client who has a personality disorder and reports that they recently used illicit drugs. Which of the following screening tools should the nurse use to determine if the client has recently used an illicit substance?

A. Fluoxetine: Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) used primarily to treat depression and anxiety disorders. It is not indicated for the treatment of tardive dyskinesia and does not address the symptoms associated with this condition. Therefore, it would not be an appropriate choice for this client.
B. Naloxone: Naloxone is an opioid antagonist used to reverse opioid overdoses. It is not relevant to the treatment of tardive dyskinesia and does not provide any therapeutic benefit in this context. Naloxone specifically targets opioid receptors, which are unrelated to the mechanisms involved in tardive dyskinesia.
C. Valbenazine: Valbenazine is specifically approved for the treatment of tardive dyskinesia. It works by decreasing the abnormal movements associated with this condition and is considered an appropriate medication for managing tardive dyskinesia symptoms. By addressing the underlying neurotransmitter imbalances, valbenazine helps improve the client's quality of life.
D. Diphenhydramine: Diphenhydramine is an antihistamine that may provide temporary relief of acute extrapyramidal symptoms, but it is not effective for managing tardive dyskinesia. Long-term use of anticholinergics like diphenhydramine is not appropriate for this chronic condition. Continued reliance on diphenhydramine could lead to other complications or side effects without resolving the issue of tardive dyskinesia.

A. Evaluation: Evaluation is the phase where the nurse assesses the effectiveness of the interventions and determines if the desired outcomes have been achieved. This phase occurs after interventions have been implemented, not during an interview.
B. Planning: Planning involves setting goals and determining the appropriate interventions for the client's care. While important, it occurs after the assessment phase and is not the stage for conducting interviews about family history.
C. Assessment: The assessment phase involves gathering comprehensive data about the client, including their history, symptoms, and family background. Interviewing the client about their family history of schizophrenia fits this phase as it aims to collect relevant information for understanding the client's condition.
D. Implementation: Implementation refers to the actual execution of the planned interventions. This phase follows assessment and planning, making it an inappropriate time for gathering family history information.
