A nurse sees smoke coming from the central supply room. Out of the following actions which should the nurse take first?

A. In the event of a fire, the nurse must follow the RACE acronym: Rescue, Alarm, Contain, Extinguish. After ensuring no one is in immediate danger in the room, the next priority is to "Alarm" by activating the pull station and notifying the facility. This ensures that the fire department and emergency response teams are mobilized to manage the hazard immediately. B. Closing windows is a component of the "Containment" phase of fire safety, which aims to limit the supply of oxygen to the fire. However, this action is secondary to notifying the authorities and ensuring the safety of individuals. Containment measures should only be performed after the alarm has been activated and the immediate area has been assessed for occupants. C. Closing doors is also part of the "Containment" (C) step in the RACE protocol, designed to prevent the spread of smoke and flames to other areas. While vital for isolating the fire, it must follow the activation of the alarm (A). Promptly alerting the entire facility ensures that all staff can begin evacuation procedures for their respective patient populations. D. Wrapping clients in blankets may be necessary during an actual evacuation to protect them from smoke inhalation or cold, but it is not the first action. The nurse must first alert the system so that collective help can arrive. Individual patient care actions during a fire follow the fundamental steps of alerting the team and containing the threat.
