During an admission assessment, a client reports currently using heroin. Which information is most important for the nurse to consider in the plan of care?

A. Feelings of disorientation may be a symptom of heroin use, but addressing the client’s mental health, particularly suicidal tendencies, takes precedence. B. Undiagnosed social anxiety symptoms may be important for long-term care, but the immediate concern is the risk of self-harm or overdose. C. Family history of schizophrenia is relevant for mental health but does not take priority over assessing suicide risk in a client using heroin. D. A history of suicide attempts is crucial for the nurse to consider because individuals using heroin may be at an increased risk of self-harm due to the psychological effects of substance use and potential for overdose. Immediate safety and suicide risk assessment are critical.
