This paper examines the significance of cultural competency within the field of nursing, specifically in relation to disaster planning and the coordination of emergency response efforts. Natural catastrophes have a substantial influence on people, families, communities, and the environment, necessitating healthcare professionals, especially nurses, to possess the necessary skills and knowledge to properly handle such circumstances. Nurses assume a pivotal role in crisis situations via the implementation of triage procedures, their provision of frontline care, and their indispensability in the face of catastrophic events. Nevertheless, there are difficulties in ascertaining the precise responsibilities and competencies of nurses in catastrophe scenarios, underscoring the need for more investigation into disaster nursing readiness. A "disaster nurse" is a role that involves three distinct stages: pre-event, during event, and post-event. Nurses are required to possess the requisite comprehension, competencies, and expertise to identify potential hazards, develop suitable methods for recuperation, and provide all-encompassing healthcare to people, families, and communities throughout the entirety of a calamity. Studies indicate that nurses often experience psychological unpreparedness and voice apprehensions about their competence in catastrophe scenarios. The preparedness of nurses for catastrophes is contingent upon several aspects, including their technical competencies, previous involvement in disaster management, and engagement in catastrophe simulations. During emergency response, nurses assume several roles, including their participation as members of the response team, triage officers, caretakers, coordinators, educators, and counselors. Nevertheless, the response to catastrophes may give rise to role conflicts and obstacles, perhaps leading to nurses exhibiting hesitancy or a lack of enthusiasm to actively participate in disaster-related tasks. In order to bolster the preparation of disaster nursing, it is imperative to develop fundamental skills for training and instruction, guarantee the efficacy of response endeavors, and integrate disaster nursing into nursing curriculum. Cultural competency plays a crucial role in the field of disaster nursing, as it empowers nurses to provide care that is attuned to the distinct requirements and perspectives of varied communities. Nurses may significantly contribute to the mitigation of catastrophe impacts and the provision of comprehensive care to impacted persons and communities by acknowledging the significance of cultural competency and effectively tackling the obstacles associated with disaster nursing preparation.
