A charge nurse is orienting a newly licensed nurse and observes the newly licensed nurse imitating her behaviors. The nurse should recognize this behavior as which of the following defense mechanisms?

A. Increased time sleeping:
Increased time sleeping alone is not a specific or direct indicator of PTSD. However, changes in sleep patterns are common in individuals with PTSD, with symptoms like nightmares, insomnia, and disturbances in sleep. These disturbances can lead to increased time in bed, but this alone is not a definitive sign of PTSD.

B. Inability to express empathy:
Inability to express empathy is a complex issue and could be related to various emotional or psychological factors. While people with PTSD can experience difficulties in interpersonal relationships, including issues with empathy, this alone is not a specific indicator of the disorder. PTSD primarily involves symptoms related to re-experiencing trauma, avoidance, negative mood changes, and arousal symptoms.
C. Auditory hallucinations:
Auditory hallucinations, which involve hearing voices or sounds that others do not, are not typically associated with PTSD. This symptom is more commonly linked to conditions like schizophrenia or other psychotic disorders, but it is not specific to PTSD.

D. Difficulty concentrating:
Difficulty concentrating is a common and well-recognized symptom of PTSD. Individuals with PTSD often struggle with focus, memory, and attention due to the intrusion of traumatic thoughts and memories. This symptom can significantly impact their daily functioning and is one of the hallmark features of the disorder.

A. Contact a close relative of the client to discuss the discharge plan:
Involving close relatives or a support system can be beneficial for the client's recovery. However, it's crucial to respect the client's confidentiality and privacy. In some cases, clients might not want their relatives involved or might not have a supportive family environment, so this option should be approached cautiously and with the client's consent.

B. Refer the client to a self-help group:
This is a highly recommended action. Self-help groups like Alcoholics Anonymous (AA) provide a supportive environment where individuals with alcohol use disorder can share their experiences and coping strategies. These groups can significantly contribute to maintaining sobriety after rehabilitation.

C. Request a discharge prescription for buprenorphine for the client:
Buprenorphine is typically used to treat opioid use disorder, not alcohol use disorder. Medications like disulfiram, naltrexone, and acamprosate are more commonly prescribed to help individuals manage alcohol cravings and maintain abstinence. However, the choice of medication should be individualized and determined by a healthcare provider based on the client's specific needs and medical history.

D. Teach the client to practice systematic desensitization:
Systematic desensitization is a therapeutic technique used to treat phobias and anxieties by gradually exposing individuals to their fears in a controlled and safe manner. While it can be helpful for addressing anxiety-related issues, it's not a standard treatment for alcohol use disorder. Therapeutic interventions for alcohol use disorder often focus on behavioral therapies, counseling, and support groups.
