Disaster preparedness and management is an essential component of medical surgical nursing, as disasters create sudden, large-scale health emergencies requiring immediate, organized, and skilled responses. Nurses play a central role in all phases of disaster management, including mitigation, preparedness, response, and recovery. Their knowledge, clinical competence, leadership ability, and communication skills make them indispensable members of the disaster management team. In the mitigation phase, nurses participate in activities aimed at reducing the impact of potential disasters. They identify risks within the hospital and community, such as structural hazards, infection risks, and inadequate emergency supplies. Nurses contribute to policy development and advocate for safe infrastructure, adequate staffing, and sufficient emergency equipment. They educate patients and families about safety measures, vaccination programs, hygiene practices, and disease prevention strategies that can reduce vulnerability during disasters. In community settings, nurses collaborate with public health officials to assess community risks and promote health awareness. Preparedness involves planning and training
