Develop evacuation routes and emergency exit procedures **정답: 2** ## 해설 Conducting a comprehensive vulnerability assessment is the foundation of effective disaster preparedness planning. Options 1, 3, and 4 are important but should follow the assessment to ensure they address specific population needs. ## 심화 해설 Understanding the Priority Setting in Disaster Preparedness When developing an emergency preparedness plan for a vulnerable population shelter, the nursing process and disaster management principles dictate that assessment must always precede intervention. The correct action is to conduct a comprehensive vulnerability assessment of the shelter population. This is not simply a preliminary step; it is the foundational data-gathering phase upon which all subsequent planning depends. Pathophysiology and Theoretical Basis of Vulnerability Vulnerability in a disaster context is a complex construct. The scoping review by Del Prete et al. (2025) highlights that vulnerability is not a static label but a dynamic state defined by the intersection of exposure, sensitivity, and adaptive capacity [1]. A person’s ability to withstand a disaster like a flood is not solely determined by the hazard itself but by pre-existing health conditions, functional limitations, and social circumstances. For instance, a patient requiring dialysis, as described by Khorram-Manesh and Carlström (2026), possesses a high degree of sensitivity because their survival depends on a resource-intensive, time-critical treatment that is immediately disrupted by infrastructure failure [2]. Without first identifying that this individual is in the shelter, the nurse cannot possibly know to prioritize securing a dialysis-capable facility or backup power for a portable unit. Similarly, the systematic review by Alvarez et al. (2026) on individuals with dementia reveals that their adaptive capacity is severely compromised due to cognitive decline, making it difficult to comprehend warnings, remember evacuation routes, or self-regulate in extreme temperatures [3]. A generic evacuation plan that does not account for this cognitive vulnerability is likely to fail. Why the Other Interventions Are Secondary The remaining options represent critical interventions, but they are logically and operationally dependent on the initial assessment. - Establishing communication links (Option 1) is an essential logistical step, but its purpose is to serve the identified needs of the population. The nurse must first know what resources to request. A communication link to a hospital is futile if the assessment reveals that the shelter’s primary need is not acute care transport but rather a cold chain for insulin dependent on the number of diabetic residents identified. - Stockpiling medical supplies (Option 3) without a vulnerability assessment leads to a mismatch of resources. A generic stockpile might contain basic first-aid items but lack the specific medications identified in the population assessment, such as emergency dialysis supplies [2] or antipsychotic medications for individuals with dementia who may experience severe behavioral and psychological symptoms of distress during an evacuation [3]. - Developing evacuation routes (Option 4) is a physical safety measure that must be tailored to functional ability. An assessment derived from the findings of Del Prete et al. (2025) would differentiate between ambulatory individuals and those with mobility, visual, or cognitive barriers, ensuring that exit procedures are realistic for everyone, including those who cannot independently follow directional signage [1]. Clinical Application and the Nursing Process In the context of the NCLEX-RN, this question tests the application of the nursing process—specifically, the primacy of assessment over implementation. The public health nurse acts in a role analogous to a frontline health worker described in the evaluation of a heat resilience program by Sorensen et al. (2026). That study demonstrated that targeted training improves a health worker’s ability to identify and manage risks, but the first step in their clinical algorithm is always the identification of at-risk individuals through systematic assessment . A vulnerability assessment is the population-level equivalent of a head-to-toe assessment for an individual patient. It generates a "problem list" for the shelter population, which then directly informs the development of a tailored, effective, and patient-centered disaster response protocol. Without this step, the plan is not evidence-based and may fail to protect those with the greatest need during the critical hours of a natural disaster.References (research sources) - [1]Understanding vulnerability to flood-induced disasters: a comprehensive scoping review on at-risk individuals and evacuation challenges.Research articleDel Prete C, Valente M, Mitiku Saji A, Khorram-Manesh A, Ragazzoni L.

This assessment identifies the specific functional, medical, and social needs of the population, which then dictates all subsequent planning, resource allocation, and interagency coordination. Key Components of a Vulnerability Assessment - **Functional Needs:** Evaluate mobility limitations, reliance on durable medical equipment (e.g., ventilators, oxygen concentrators), communication barriers, and cognitive impairments. - **Medical Dependency:** Identify individuals dependent on time-critical treatments such as dialysis, insulin, or continuous IV infusions, as infrastructure failure directly threatens their survival. - **Social Vulnerability:** Assess for lack of transportation, poverty, language barriers, and social isolation, which limit an individual's adaptive capacity. Rationale for Assessment-First Approach - The nursing process mandates assessment before intervention. Without knowing the population's profile, stockpiling supplies or establishing communication links is untargeted and potentially ineffective. - Vulnerability is a dynamic state defined by the intersection of exposure, sensitivity, and adaptive capacity. A person's ability to withstand a disaster is determined by pre-existing conditions, not just the hazard itself. - All subsequent actions—evacuation planning, supply stockpiling, and agency coordination—are optimized and made specific based on the findings of the initial assessment. Core Principle: Disaster Management Cycle Evidence: Nursing Process Application in Emergency Preparedness ## 핵심 개념 - **Vulnerability Assessment** — A systematic process to identify the specific risks, needs, and functional limitations of a population to guide targeted disaster planning and resource allocation. - **Nursing Process in Disasters** — The application of the assessment, diagnosis, planning, implementation, and evaluation framework to disaster response, where assessment is the critical first step. - **Adaptive Capacity** — The ability of an individual or community to adjust to a hazard, cope with the consequences, and recover, which is a key component of vulnerability. ## 같은 주제 문제 - [A community health nurse is developing an emergency preparedness plan for a vulnerable pop…](https://mymerci.kr/pages/nclex_q.php?qn_id=542809) - [A community health nurse is developing an emergency preparedness plan for a vulnerable pop…](https://mymerci.kr/pages/nclex_q.php?qn_id=542810) --- More free questions: [기출문제](https://mymerci.kr/) _학습 참고용입니다. 실제 임상은 최신 지침과 소속 기관 프로토콜을 따르세요._
