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. Replace paper trash bags with plastic biohazard bags: This does not directly contribute to a safer milieu for the client and is generally related to infection control rather than mental health safety. B. Take the client's cellular telephone and provide a telephone in the room: While controlling phone access can sometimes be necessary, it is not a primary measure for ensuring environmental safety in this scenario. C. Ensure that prescribed medications are kept in a safe place in the room: Medications should not be kept in the client's room, as they need to be securely stored and administered by healthcare staff to prevent misuse or overdose. D. Remove soft drink cans from the nurse's desk and patient lounge: In a mental health setting, it's crucial to minimize environmental risks. Soft drink cans can potentially be used as a weapon or for self-harm, so removing them helps maintain a safe environment for all clients.
