A nurse is working in an emergency department and observes a client beginning to shoot at staff with a gun. Which of the following actions should the nurse take? (Select all that apply.)

Rationale: A. This option is correct because the priority during an active shooter situation is personal safety. If there is a safe path available, the nurse should run to the nearest exit to escape the danger, following the “Run, Hide, Fight” principle. B. This option is correct because warning other staff to leave quickly helps reduce the number of potential victims and promotes rapid evacuation when it is safe to do so. C. This option is correct because if escape is not possible, the nurse should move to a hidden location out of the shooter’s view, lock or barricade doors if possible, silence phones, and remain quiet to reduce the risk of being found. D. This option is incorrect because assisting wounded individuals should only occur once the area is secure. Attempting to help others during an active shooting places the nurse at significant risk. E. This option is incorrect because screaming at the shooter could draw attention to the nurse and escalate the situation, increasing the risk of harm. F. This option is incorrect because blocking people from entering the area is not a priority during an active shooter event and could place the nurse in further danger. Law enforcement is responsible for securing the area once they arrive.
