A client is admitted to the mental health unit for feelings of depression secondary to a positive HIV report. To provide a safe milieu for this client, which action should the nurse take?

A. Ensuring medications are kept in a safe place is important but may not directly impact safety in the milieu. B. Replacing paper trash bags with biohazard bags is unnecessary unless there is a specific reason related to infection control. C. Removing soft drink cans can prevent them from being used inappropriately (e.g., for self-harm or as weapons), contributing to a safer environment. D. Taking the client's cellular telephone and providing a room telephone may be necessary for some clients but is not a universal safety measure.
