A nurse in an inpatient mental health facility observes a client who is becoming increasingly angry. Which of the following actions should the nurse take first?

Introduction: De-escalation of the agitated client requires a hierarchical approach prioritizing safety, environmental control, and the least restrictive intervention to prevent injury to the client or healthcare staff. A. Walking with the client to release energy is a therapeutic de-escalation technique that may help some individuals. However, before engaging closely with an increasingly angry client, the nurse must prioritize safety. Without adequate backup, this action could place the nurse at high risk for physical assault during a sudden outburst. B. Administering tranquilizing medication, often referred to as chemical restraint, is a restrictive intervention used when verbal de-escalation fails. It is not the first action, as the nurse should always attempt less invasive measures first. Furthermore, preparing and administering medication takes time, during which the environment must be secured. C. Ensuring enough staff are available is the priority action because it provides "show of force" which can often de-escalate a client through a non-threatening presence. Most importantly, it ensures the safety of everyone on the unit should the client's anger progress to physical aggression or violent behavior. D. Placing a client in seclusion is a highly restrictive intervention and should only be used as a last resort when the client poses an immediate threat to themselves or others. Using seclusion before attempting less restrictive measures or ensuring adequate staffing violates the principle of using the least restrictive environment.
