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. Cancer: While individuals with schizophrenia may have an increased risk of certain health issues, cancer is not typically identified as a common comorbidity directly associated with schizophrenia. Other factors may influence cancer risk, but it is not a prevalent comorbidity.
B. Diabetes mellitus: Diabetes mellitus is a well-documented comorbidity in clients with schizophrenia. Factors contributing to this association include lifestyle choices, medication side effects (such as weight gain from antipsychotics), and metabolic syndrome, leading to a higher prevalence of diabetes among this population.
C. Alzheimer's disease: Alzheimer's disease primarily affects older adults and is not commonly associated as a comorbidity of schizophrenia. While both conditions involve cognitive changes, Alzheimer's is not a direct comorbidity of schizophrenia.
D. Osteoarthritis: Osteoarthritis is a degenerative joint disease primarily related to aging and wear and tear on joints. It is not specifically linked to schizophrenia as a comorbidity and does not directly impact the management of schizophrenia.

A. When attending dialectical behavior therapy: While individuals with borderline personality disorder may experience emotional distress during therapy sessions, attending dialectical behavior therapy (DBT) typically provides skills and support to manage emotions and reduce self-harm risks. Therefore, this situation is not considered the highest risk.
B. When attending narrative therapy: Narrative therapy focuses on helping individuals reframe their stories and experiences, which can be beneficial. While any therapeutic setting can evoke emotions, attending narrative therapy does not significantly increase the risk of self-harm compared to other situations.
C. When discharged from the hospital: This situation is often associated with the highest risk for self-harm. The transition from a controlled environment to the challenges of everyday life can lead to feelings of abandonment, loss of support, and increased stress, making individuals vulnerable to self-harming behaviors.
D. When getting married: While significant life changes, such as marriage, can evoke anxiety, they do not typically represent the highest risk for self-harm. The supportive context of a marriage and the associated positive emotions usually outweigh the potential for increased risk at that moment.
