A client reveals he has a loaded revolver at home and will probably use it. What is the nurse's immediate priority?

In situations where a client expresses intent to harm themselves and has access to a loaded firearm, the immediate priority is to ensure their safety. Initiating plans for hospitalization provides the necessary intervention to address the risk of suicide and allows for close monitoring and evaluation by mental health professionals.

Hospitalization can provide a safe environment where the client can receive appropriate psychiatric care, engage in therapy, and be assessed for risk factors more thoroughly. The urgency of the situation requires immediate protective measures rather than relying on strategies that may not provide the necessary support or assurance of safety. Utilizing hospitalization minimizes the risk of self-harm and addresses the psychological distress the client may be experiencing.

Other actions, such as asking the client to remove the firearm, having them call hourly, or obtaining a promise not to harm themselves, do not adequately guarantee the client's safety or actively address the immediate threat posed by the gun. These options may not be effective in preventing potential harm, as they place responsibility on the client rather than providing direct support and intervention.
