A nurse in an emergency department is caring for an adolescent following a suicide attempt. After reviewing the client's history, the nurse should determine which of the following is the priority risk factor for suicide completion.

Rationale: A. A previous suicide attempt is a significant risk factor but not necessarily the single greatest predictor of completion. B. An active psychiatric disorder, such as major depression or bipolar disorder, is the highest priority risk factor for suicide completion because it directly affects mood, judgment, and impulse control. C. Loss of a parent can contribute to emotional stress but is not the primary risk factor for suicide completion. D. History of substance abuse increases risk by impairing judgment and increasing impulsivity but is secondary to an active psychiatric disorder in predicting suicide completion.
