Which of the following is the priority action by the nurse for a client with symptoms of depression who admits to thoughts of self-harm with a plan, and has a history of borderline personality disorder, depression, and substance abuse?

Choice A reason:While reviewing the client's toxicology laboratory report is important to understand any substance use that may be contributing to the client's current state, it is not the immediate priority. The priority is to ensure the client's safety.Choice B reason:Initiating suicide precautions is the most critical and immediate action when a client admits to thoughts of self-harm with a plan. This involves creating a safe environment, providing constant supervision, and possibly removing harmful objects to prevent the client from acting on these thoughts.Choice C reason:Administering the Hamilton Depression Scale can help in assessing the severity of depression, but it is not the first priority. The immediate concern is to protect the client from self-harm.Choice D reason:Making a contract with the client for behavior in the unit can be a useful part of the treatment plan, particularly for clients with borderline personality disorder. However, it is not the first action to take when a client is at immediate risk for self-harm.
