A 29-year-old client with schizophrenia is brought to the emergency department by police after being found wandering into traffic while shouting about government surveillance. The client is disoriented, agitated, and refuses treatment, stating, "You're trying to poison me with your drugs. Based on legal and clinical criteria for involuntary psychiatric admission, which of the following best justifies the nurse's support for initiating involuntary commitment?

Rationale: A. While medication noncompliance and repeated hospitalizations are concerning, they do not alone meet the threshold for involuntary admission without immediate risk. B. Refusal of treatment and lack of insight (anosognosia) are common in schizophrenia but do not justify involuntary admission unless there is risk of harm. C. Family concerns are important but not sufficient by themselves to justify involuntary commitment. D. Involuntary admission is legally justified when a person poses a danger to themselves or others due to mental illness. Wandering into traffic while disoriented and paranoid demonstrates an imminent safety risk.
