A nurse is caring for a client who has become violent and is threatening self-harm following a crisis. After ensuring enough staff are available, which of the following actions should the nurse take first?

A. Administer a sedative medication: Medication may be necessary if the client remains highly agitated or dangerous after verbal interventions fail. However, pharmacologic measures are not the initial approach; attempting to de-escalate the situation verbally is the first priority. B. Perform a debriefing with the staff: Staff debriefing is an important step after the crisis has been resolved to evaluate interventions and emotional impact. It is not an immediate action during an active episode of violence or self-harm risk. C. Acknowledge the client’s emotions: Recognizing and verbalizing the client’s feelings demonstrates empathy and can help de-escalate agitation. This therapeutic communication technique shows understanding, reduces perceived threat, and may prevent escalation to violence or self-harm. D. Place the client in restraints: Restraints are a last-resort intervention used only when less restrictive measures fail and the client poses imminent danger. The nurse must first attempt verbal de-escalation and emotional validation before resorting to physical control.
