NLE Disaster Nursing & Crisis Response — Disaster Nursing & Emergency PreparednessStudy Notes

A disaster is defined as any sudden event that overwhelms local resources and capacity to respond, resulting in significant damage, destruction, and human suffering. Unlike an everyday emergency in a hospital (e.g., a patient code blue), a disaster exhausts healthcare infrastructure and requires a shift in both mindset and practice. In the Philippines, disasters are broadly classified into two categories: (1) Natural disasters—typhoons, earthquakes, volcanic eruptions, floods, tsunamis, landslides, and droughts—which are weather-related or geologic in origin; and (2) Man-made or technological disasters—industrial accidents, chemical spills, fires, transportation crashes, structural collapse, terrorism, and armed conflict—which result from human action or negligence. The Filipino nursing graduate preparing for the NLE must recognize that a 'disaster' is defined not by the event alone but by its impact: a typhoon that strikes an unprepared rural barangay is a disaster, whereas the same storm bypassing a well-prepared city may cause only minor disruption. This reinforces the central nursing role in mitigation and preparedness—reducing the impact long before the event occurs. The key conceptual shift in disaster care is ethical and utilitarian: triage and resource allocation prioritize saving the maximum number of lives, not the individual with the most severe injury. In everyday nursing (e.g., an emergency department), you treat the sickest patient first; in a mass-casualty disaster, you treat the salvageable patient who will die without intervention, deferring those who are clearly expectant or only minor casualties.

Disaster management is not a single response event but a continuous, cyclical process. The four phases form the backbone of all disaster planning and are the most-tested framework on the NLE. Each phase has distinct nursing roles and responsibilities aligned with RA 10121 and the National Disaster Risk Reduction and Management Council (NDRRMC) structure. Understanding the timing and goals of each phase is essential for answering NLE scenario questions. **Phase 1: Mitigation** occurs *before* a disaster and focuses on preventing or reducing the impact of future hazards. Mitigation is the longest-term, most cost-effective investment. Nursing roles in mitigation include participating in hazard mapping and vulnerability analysis (identifying which health facilities, water systems, or communities are at highest risk), advocating for building codes and structural reinforcement of health facilities, educating the public about hazard risks and safe practices (e.g., teaching communities to avoid landslide-prone slopes), supporting land-use planning to discourage settlement in high-risk zones, and collaborating with barangay officials on mangrove restoration and flood-control projects. A nurse working in community health (NCM Level III) might conduct a hazard-vulnerability analysis of a rural health unit, identifying that it has only one generator, lies in a flood-prone area, and has no backup water supply—findings that drive facility improvements. **Phase 2: Preparedness** occurs *before* a disaster and focuses on planning and readiness so that response is swift and effective. The goal is 'readiness'—systems, supplies, and personnel are primed. Nursing roles include participating in the development and regular testing of facility and community disaster plans (e.g., annual drills), training responders in triage and basic disaster response, ensuring stockpiles of medications (antibiotics, antidotes, IV fluids) and supplies (gauze, bandages, stretchers, shelters, water tanks) are maintained and rotated, establishing early-warning systems and communication chains (e.g., a barangay alert system by text and radio), and preparing family go-bags. A well-prepared barangay has evacuation routes marked, shelters identified, communication drills conducted quarterly, and residents educated on what to do before and during a typhoon. **Phase 3: Response** occurs *during and immediately after* the disaster and focuses on saving lives and preventing further harm. This is the acute phase, lasting hours to days. Nursing priorities are search and rescue, rapid triage using the START system, emergency treatment of life-threatening injuries, evacuation to safe areas, establishing shelters and ensuring safety, meeting immediate survival needs (drinking water, food, sanitation, safety from aftershocks or secondary hazards), and establishing disease surveillance. A nurse on a disaster response team arrives at the scene, ensures her own safety and that of the team, begins triage of the injured, applies first aid and referral to hospitals, and supports the re-establishment of basic healthcare. **Phase 4: Recovery** occurs *after* the response phase and is the longest phase, lasting weeks to years. The goal is to restore the community to normal or improved functioning. Nursing roles include providing ongoing physical health care (wound management, immunisation, infectious-disease control), supporting mental health and psychosocial recovery, conducting disease surveillance, ensuring water and sanitation safety, evaluating the response to identify what worked and what did not (feeding lessons learned back into mitigation planning), and supporting the rebuilding of infrastructure. After Typhoon Haiyan, recovery in Tacloban included reconstructing health facilities, restoring medical supply chains, treating displaced persons in temporary shelters, screening for waterborne and vector-borne diseases, and documenting the disaster's mental health sequelae. A key nursing insight: mitigation and preparedness happen in the quiet periods between disasters; they receive less media attention than response but save far more lives. The NLE often tests whether you recognize that investing in mitigation and preparedness—not just response—is the nurse's professional duty.

In a mass-casualty incident (MCI), you cannot treat all victims simultaneously; triage—rapid, systematic sorting—determines who receives care first. The most widely taught triage system for adults is **START (Simple Triage And Rapid Treatment)**, which classifies victims into four colour-coded categories in under 60 seconds per person. START is designed for speed and simplicity; a trained responder (nurse, paramedic, emergency responder) with only a triage tag and a watch can sort hundreds of victims, ensuring that salvageable lives are treated first. This is a high-yield, frequently tested NLE concept because triage accuracy directly determines survival. **The START Sequence** follows a specific order: **Step 1: Ambulation.** Upon arrival at the scene, the triage officer calls out loudly: 'If you can walk, get up and walk to this area (pointing to a designated safe location).' Everyone who walks to that area is immediately tagged **GREEN (Priority 3—Minor)**. This accomplishes two goals: it rapidly segregates the walking wounded (who will wait longest for treatment) and allows the responder to focus on the remaining non-ambulatory victims, reducing the crowd at the triage point. **Step 2–4: RPM Assessment.** For victims who remain (i.e., cannot walk), assess in the strict order: **R (Respirations) → P (Perfusion) → M (Mental status)**. If any assessment result directs you to a category, you assign that colour and move to the next victim; you do not continue assessing. **Respirations (R):** Look for spontaneous breathing. - If the victim is **not breathing**, attempt to open the airway (head tilt, chin lift, or jaw thrust). - If breathing resumes after airway opening → tag **RED (Priority 1—Immediate).** - If breathing does not resume → tag **BLACK (Priority 4—Deceased/Expectant).** - If the victim is already breathing, count respirations. If **> 30/minute** → tag **RED.** - If respirations are **≤ 30/minute**, proceed to Perfusion. **Perfusion (P):** Check the **radial pulse** (felt at the wrist) or **capillary refill** (press the nail bed, release, and observe colour return). - If radial pulse is **absent** → tag **RED.** - If capillary refill is **> 2 seconds** (slow) → tag **RED.** - If perfusion is adequate, proceed to Mental status. Also control any major bleeding while assessing perfusion. **Mental Status (M):** Give a simple command such as 'Squeeze my hand' or 'Open your eyes.' - If the victim **cannot follow a simple command** (or is unconscious) → tag **RED.** - If the victim **can follow the command** → tag **YELLOW (Priority 2—Delayed).** **The Four START Categories** are colour-coded and correspond to treatment priority: **RED (Priority 1—Immediate): Salvageable, life-threatening injuries needing intervention now.** These are victims who will die without immediate treatment but have a reasonable chance of survival with care. Examples: airway compromise (choking, severe maxillofacial trauma), severe uncontrolled bleeding (femoral artery, brachial artery), signs of shock (pale, cold, weak pulse, altered mental status), RR > 30, absent radial pulse, capillary refill > 2 seconds, or inability to follow commands. RED victims are treated **first** at the disaster site or evacuation hospital. In a mass-casualty scenario, if you have 5 treatment stations and 20 RED victims, the RED victims rotate through those stations continuously; YELLOW and GREEN are triaged only after RED patients are stable or evacuated. **YELLOW (Priority 2—Delayed): Serious, stable injuries; treatment can wait a short time without threat to life or limb.** These victims have injuries that need care but are not immediately life-threatening. Examples: stable fractures (femur fracture with intact neurovascular status), moderate burns without airway involvement (e.g., 15% TBSA on extremities), abdominal pain without signs of shock, and uncomplicated head injuries with intact mental status. YELLOW victims may wait hours for definitive care without grave risk. **GREEN (Priority 3—Minor): The walking wounded; minor injuries; can wait longest and often assist responders.** These victims include those with minor lacerations, sprains, minor fractures, and minor burns. They can walk, communicate, and often help others; some may assist with water distribution, first aid, or shelter setup. In some disasters, the majority of casualties are GREEN. **BLACK (Priority 4—Expectant/Deceased): Dead, or injuries so severe that survival is unlikely even with maximum care.** These are victims with massive head or truncal trauma, full-thickness burns > 90% TBSA, or other incompatible-with-life injuries, and victims who are deceased. In a mass-casualty setting, BLACK victims receive **comfort care only** (water, shade, emotional presence) because expending resources on them would divert care from RED and YELLOW victims, ultimately resulting in fewer lives saved. This is the most ethically difficult aspect of disaster nursing—accepting that the sickest, most severely injured patients do not receive intensive intervention in a mass-casualty event—but it is the correct approach under utilitarian ethics and RA 10121's disaster management framework. **Critical NLE Insight:** A victim with a catastrophic head injury and an absent radial pulse is BLACK, not RED, because she is not salvageable; treating her would consume resources (oxygen, IV fluids, transport, personnel time) that could save a RED victim with a tension pneumothorax (who is salvageable). Prioritizing salvageable RED victims over non-salvageable BLACK victims is morally sound disaster nursing. **Re-triage:** Conditions change; a RED victim may improve and drop to YELLOW, or a YELLOW victim may deteriorate to RED. Disaster sites are chaotic, and triage is reassessed as victims move through the system. The triage officer or treatment nurses re-triage victims frequently.

**CBRN** stands for Chemical, Biological, Radiological, and Nuclear events—either accidental releases or deliberate attacks using hazardous agents. CBRN events produce mass casualties and require specialized protective equipment (PPE), decontamination procedures, and antidote administration. The Philippines faces risk from industrial chemical facilities, disease outbreaks (biological threats), and the remote but real possibility of radiological or nuclear terrorism. Nurses must understand the characteristics of each agent, the protective measures, and the immediate interventions. **CHEMICAL AGENTS** are toxic substances that cause rapid onset of symptoms (minutes to hours). Major classes include: (1) **Nerve agents** (e.g., sarin, VX) inhibit acetylcholinesterase, causing excessive cholinergic stimulation. Victims experience miosis (pinpoint pupils), excessive salivation and lacrimation ('watering' of eyes and tears), muscle fasciculations, seizures, respiratory paralysis, and death if untreated. Treatment: immediately remove from exposure, remove clothing, irrigate skin and eyes with copious water, administer **atropine** (reverses cholinergic effects) and **pralidoxime (2-PAM)** (reactivates acetylcholinesterase); atropine is auto-injectors (e.g., Mark I kits). (2) **Blister agents** (e.g., mustard gas, lewisite) cause severe blistering, eye damage, and respiratory injury; treatment is decontamination and supportive care. (3) **Choking agents** (e.g., chlorine, phosgene) damage the lungs; victims have respiratory distress and pulmonary edema; treatment is removal from exposure, oxygen, and supportive ventilation. (4) **Blood agents** (e.g., cyanide) inhibit cellular respiration; victims collapse rapidly and become cyanotic; treatment is removal from exposure and, for cyanide, administration of cyanide antidote kits (e.g., sodium thiosulfate, hydroxocobalamin). **BIOLOGICAL AGENTS** are pathogens or toxins that cause disease. Onset is delayed (incubation period, often days to weeks), so recognition often comes from public-health surveillance—clusters of unusual illness. Major agents include: (1) **Anthrax** (bacterium Bacillus anthracis); inhalation anthrax causes severe respiratory illness and is often fatal without treatment; cutaneous anthrax appears as a black eschar on skin (hence 'anthrax'); treatment is antibiotics (ciprofloxacin or doxycycline). (2) **Plague** (bacterium Yersinia pestis); bubonic plague presents with painful, swollen lymph nodes (buboes); septicemic and pneumonic forms are severe; treatment is antibiotics. (3) **Smallpox** (eradicated in nature but a concern for bioterrorism); highly contagious; causes a characteristic rash that progresses through macules, papules, vesicles, and pustules; treatment is supportive care and strict isolation; vaccination can prevent or reduce severity. (4) **Botulism** (toxin from Clostridium botulinum); causes flaccid paralysis, respiratory failure; treatment is supportive ventilation and antitoxin. The key priority in a biological event is **isolation, infection control, prophylaxis (e.g., antibiotics or vaccination), and public-health reporting**. Because biological agents have delayed onset, early recognition depends on surveillance—astute clinicians noticing an unusual cluster of respiratory illness or unexplained deaths and reporting to the Department of Health (DOH). **RADIOLOGICAL EVENTS** involve dispersal of radioactive material (e.g., a radiological dispersal device or 'dirty bomb'). Effects depend on the isotope, quantity, and dispersal method. Immediate priorities are **maximizing distance from the source** (move away and upwind if possible), **minimizing time spent near the source** (limit exposure duration), and **increasing shielding** (dense materials like lead or concrete block radiation). Decontamination involves removing outer clothing and washing skin with soap and water. Long-term effects include increased cancer risk and radiation sickness (nausea, vomiting, diarrhea, bone-marrow suppression) depending on dose. For **radioactive iodine** exposure, **potassium iodide (KI)** given orally saturates the thyroid with stable iodine, preventing uptake of radioactive iodine and protecting the thyroid; KI is most effective if given before or shortly after exposure. Treat life-threatening conventional injuries (e.g., blast trauma) first; radiation effects are addressed after stabilization. **NUCLEAR EVENTS** (nuclear weapon detonation) cause blast injury (pressure waves, structural collapse), thermal injury (intense heat causing burns at great distances), and radiation (prompt radiation and residual fallout). Blast and thermal injuries are treated like any trauma; radiation protection follows the **time-distance-shielding principle**. After-blast, move away from the blast zone, seek shelter (basement of a building, interior room away from windows), and remain sheltered until radioactive fallout settles (typically 24–48 hours). **Overarching CBRN Priorities:** (1) **Protect the responder first.** An incapacitated nurse is useless; appropriate PPE (mask, gown, gloves, eye protection) must be donned before approaching a CBRN scene. (2) **Decontamination before treatment.** Contaminated victims must be decontaminated (remove clothing, irrigate with water, sometimes use dilute bleach for biological agents) *before* entering the treatment area to prevent secondary contamination of staff and supplies. Exceptions: if a victim has immediately life-threatening injuries (airway compromise, massive hemorrhage), life-saving interventions (airway intubation, tourniquet application) are performed first, but decontamination follows immediately after. (3) **Follow the incident command structure.** CBRN events activate the Incident Command System (ICS); the incident commander, hazmat teams, and medical teams work in coordinated zones: **hot zone** (contamination area; entry only by fully protected hazmat personnel), **warm zone** (decontamination and initial triage; PPE required), **cold zone** (treatment area; standard precautions). (4) **Recognize the agent and administer specific antidotes or prophylaxis.** A victim with pinpoint pupils, excessive salivation, and muscle fasciculations is a nerve-agent victim requiring atropine and pralidoxime; a cluster of patients with fever, respiratory symptoms, and mediastinal widening on chest X-ray suggests inhalation anthrax requiring antibiotics. **Philippine Context:** The Philippines' industrial sector includes chemical manufacturing and mining; the presence of biological pathogens (dengue, typhoid) makes biological surveillance important; and terrorism, though not endemic, is a national security consideration in Mindanao and other conflict-affected areas. The DOH and the Philippine National Police (PNP) maintain CBRN response units. Nurses in disaster-response roles may be called to support CBRN events, particularly in decontamination and initial treatment.

Disaster nursing in the Philippines operates within a specific legal and organizational framework established by **RA 10121 (Philippine Disaster Risk Reduction and Management Act of 2010)** and enforced through the **National Disaster Risk Reduction and Management Council (NDRRMC)**. Understanding this framework is essential because it defines the nurse's role, the hierarchy of command, and the coordination of health and non-health agencies. **RA 10121** represented a paradigm shift from *reactive disaster response* (reacting after the disaster) to *proactive disaster risk reduction and management (DRRM)*. The Act emphasizes that disasters can be prevented or their impact reduced through planning, mitigation, and preparedness before the event occurs. This aligns with evidence-based disaster management globally and with RA 9173 (Philippine Nursing Law), which mandates that nurses promote health, prevent disease, and restore wellness—roles that extend to community disaster preparedness. **The NDRRMC** is the national coordinating body for disaster risk reduction and management. It is chaired by the Department of National Defense (DND) and includes representatives from the Department of Health (DOH), Department of Interior and Local Government (DILG), Department of Social Welfare and Development (DSWD), and other agencies. The structure cascades down: each province has a Provincial DRRMC, each municipality has a Municipal DRRMC, and each barangay has a Barangay DRRMC. This hierarchical structure ensures that disaster planning, resource allocation, and response are coordinated from the national level to the smallest administrative unit. **The DOH's role in disaster management** includes coordination of the health sector's response, pre-positioning of emergency supplies (medications, IV fluids, dressing materials, tents, generators), training and deployment of rapid assessment and response teams (RARTs), surveillance for communicable diseases, and mental health support. The **Philippine Health Incident Management Team (PHIMT)** and **DOH regional offices** coordinate the health-sector response under the Incident Command System (ICS). **The Incident Command System (ICS)** is the standardized command-and-control structure used in disaster response to coordinate multiple agencies (health, police, fire, military, utilities, etc.). The ICS establishes clear chains of command, defines roles (incident commander, operations chief, logistics chief, planning chief), and ensures efficient resource allocation. In a disaster, a unified command (headed by the incident commander, often the municipal mayor) coordinates all responding agencies. Nurses working at the field hospital, triage point, or shelter operate within the ICS structure, taking directions from the health-sector commander or the incident commander's health liaison. **Nursing roles within the legal framework** include: (1) **Advocacy and participation in DRRM planning** at barangay, municipal, and hospital levels—attending council meetings, contributing to disaster plans, and ensuring that health-sector needs are represented. (2) **Hazard-vulnerability analysis**—identifying risks to health infrastructure and recommending mitigation (e.g., the rural health unit needs a backup generator because floods disable the main supply). (3) **Training and drills**—conducting disaster training for healthcare workers, community members, and volunteers; leading quarterly evacuation drills in schools and facilities. (4) **Community education**—teaching families about family disaster plans, evacuation routes, go-bag contents, and post-disaster health protection. (5) **Response roles**—rapid triage, emergency care, evacuation, establishing shelters, disease surveillance, and psychological first aid. (6) **Documentation and reporting**—recording triage decisions, injuries treated, deaths, and epidemiological data for the DOH's post-disaster evaluation and response improvement. **RA 9173 and Nursing Practice** explicitly include disaster nursing and community health as core areas of nursing competence. Nurses are obligated under RA 9173 not only to care for individual patients but to advance the health of the public, which encompasses disaster risk reduction, emergency preparedness, and disaster response. The NLE examines this legal responsibility through scenario questions (e.g., 'As a nurse in a rural barangay, how do you contribute to disaster preparedness?'). **Community-level preparedness** in the Philippine context is critical because many disasters strike rural and remote areas where hospitals and resources are distant. A well-prepared barangay has: (1) an updated barangay disaster plan (revised annually); (2) identified and trained volunteer rescuers and first-aiders; (3) pre-positioned supplies (tents, food, water, first-aid kits); (4) marked evacuation routes and designated shelters (e.g., the barangay hall, a school building on high ground); (5) an early-warning system (radio, text alerts, sirens) and communication chain (barangay officials, health workers, community leaders); (6) family disaster plans and go-bags in households; and (7) regular drills (quarterly for barangays in typhoon-prone areas, annually for others). The barangay health worker (BHW) and rural health midwife (RHM)—often the only health professionals present—are key coordinators of community preparedness. **The DOH's pre-positioned resources** include emergency response teams, medicines, supplies, and equipment strategically located in each region. After a major disaster, the DOH's disaster response coordinator activates national response teams, deploys them to the affected region, and coordinates with the NDRRMC and local government units (LGUs). Hospitals receive alerts to prepare for mass casualties, establish field hospitals if needed, and receive additional supplies and personnel. **Post-disaster evaluation and feedback** is mandated by RA 10121. After a disaster response, the NDRRMC, DOH, and LGUs conduct an after-action review (AAR) to identify what worked, what did not, and what needs improvement. Nurses contribute to this evaluation by documenting what they observed, what resources were lacking, what training needs emerged, and recommendations for future preparedness. This feedback is fed back into the mitigation and preparedness phases, creating a continuous improvement cycle.

Disasters inflict psychological as well as physical harm. Survivors face acute stress reactions, grief, fear, displacement, and loss of livelihood. If unaddressed, these psychological effects can evolve into post-traumatic stress disorder (PTSD), depression, and anxiety disorders. The World Health Organization (WHO) and the Philippine Psychiatric Association recommend **Psychological First Aid (PFA)** as the evidence-based approach to early psychosocial support in disasters. Importantly, PFA is **not formal psychotherapy** and is not 'debriefing' (in fact, routine debriefing—forcing survivors to recount their traumatic experience—is no longer recommended in early disaster phases because it can worsen distress). PFA is practical, compassionate, non-invasive support provided by trained responders (including nurses) in the hours and days following a disaster. **What is Psychological First Aid (PFA)?** PFA is a non-intrusive, human-centred approach that addresses survivors' immediate emotional, physical, and social needs and connects them with services. The core actions are often summarized as **Look, Listen, and Link**: **Look** – observe the scene for obvious safety hazards, people with obvious urgent physical or mental-health needs (extreme distress, self-harm behavior, confused/disoriented persons, unattended children, separated families), and those in distress who may not self-identify. Use your clinical judgment: a survivor sitting alone, withdrawn, not eating, or muttering to themselves may be in acute psychological crisis and benefit from PFA. **Listen** – approach the person respectfully, ask about their immediate needs and concerns, listen without judgment, and help them feel calm. Do NOT ask them to describe the traumatic event in detail ('Tell me exactly what happened'); instead, ask practical questions: 'Are you safe now?', 'Do you have water and food?', 'Have you been reunited with your family?', 'Is there someone we can call for you?'. Listening itself is therapeutic; it conveys that their concerns are heard and valued. **Link** – connect survivors with: (1) **basic needs** (water, food, shelter, safety), (2) **accurate information** (how the response is progressing, when supplies are expected, where to access medical care or mental health support), (3) **their loved ones and social support** (help find separated family members, facilitate phone calls, reconnect with community), and (4) **professional services** if warranted (if a survivor shows signs of severe distress, self-harm, or psychiatric crisis, refer to a mental health professional). **The Five Principles of PFA** underlying all actions are: 1. **Promote safety.** Ensure the immediate environment is safe; remove the person from ongoing hazards (aftershocks, flooding, fires, security threats). Feeling safe is foundational to any psychological recovery. 2. **Promote calming.** A calm, steady presence of the responder is powerful; speak in a quiet, reassuring tone, provide a quiet space away from chaos if possible, and offer simple comfort (a chair, water, a blanket). Anxiety is contagious; the responder's calmness helps calm the survivor. 3. **Promote self- and community efficacy.** Help survivors recognize their own strengths and the community's resources. Statements like 'You made it through the initial disaster; you are strong' or 'This barangay has come together to help each other before; we will recover' build hope and a sense of agency. Engage survivors in rebuilding (helping distribute supplies, participating in shelter organization, volunteering) to restore a sense of purpose. 4. **Promote connectedness.** Isolation worsens psychological distress. Family reunification is a priority; facilitate communication with loved ones; group survivors by family or community; encourage peer support among survivors. 5. **Promote hope.** Provide realistic, honest information about the disaster response and recovery timeline. Uncertainty worsens anxiety; knowing that additional supplies are arriving, that search and rescue is ongoing, or that a family member was seen being transported to hospital reduces the sense of helplessness. **Implementation of PFA in Disasters:** Early (hours–days): In evacuation centres and shelters, nurses trained in PFA can identify survivors in distress, provide listening support, help reunite families, ensure basic needs are met, and refer severe cases for professional mental health care. Practical interventions include: (1) establishing a family reunification centre with photos and identification, (2) providing basic information regularly (via announcements or posted notices) about response progress and available services, (3) creating quiet areas in shelters for people to rest, (4) facilitating peer support groups (informal gatherings where survivors support each other), and (5) involving willing survivors in purposeful activities (food preparation, childcare, shelter organization). Medium term (weeks): Nurses and mental health workers conduct clinic sessions in shelters, identifying and treating acute stress disorder, depression, and anxiety. Ongoing PFA, grief counseling (for those who lost loved ones), and reconnection activities continue. Late term (months–years): Establish community mental health clinics, train community health workers in basic mental health support, and provide referrals for PTSD and other complex psychological conditions to specialists. **Red Flags for Severe Psychological Distress** that warrant referral to a mental health professional: active suicidal or homicidal ideation, severe panic attacks, dissociation or 'freezing,' aggressive behavior, psychotic symptoms (hallucinations, delusions), or inability to meet basic self-care needs (not eating, not sleeping, poor hygiene). In these cases, a nurse should not attempt counseling alone; connect the person with a psychiatrist, psychologist, or trained mental health counselor. **Responder Self-Care:** Nurses and disaster responders are exposed to graphic injuries, death, the grief of survivors, and the stress of chaotic, resource-limited situations. Vicarious trauma, compassion fatigue, and burnout are real occupational hazards. Self-care strategies include: (1) adequate sleep and nutrition (responders eat and rest in shifts), (2) peer support among responders, (3) limiting continuous shifts to 12–14 hours (fatigue impairs judgment), (4) debriefing among responders (NOT survivors) to process emotional stress, and (5) access to mental health support for responders after the disaster. A burned-out, traumatized nurse is less effective and at risk of errors; caring for yourself is essential to sustaining your ability to care for others. **Philippine Context:** The Department of Health's Disaster Risk Reduction and Management Division includes psychosocial support programs. After major disasters (e.g., Typhoon Haiyan, Marawi siege), the DOH and NGOs (e.g., Philippine Red Cross, Doctors Without Borders) deployed mental health teams. Local psychiatrists, psychologists, and trained BHWs provided psychological first aid and ongoing mental health support. The challenge in rural Philippines is limited mental health infrastructure; many barangays lack access to psychiatrists or psychologists, so training BHWs and community volunteers in basic PFA and mental health awareness is essential.

Disaster nursing integrates clinical assessment, triage, emergency care, infection control, health promotion, and coordination within the healthcare system and incident command structure. The following evidence-based nursing priorities guide response and are frequently tested on the NLE. **Priority 1: Scene Safety and Personal Protection.** Upon arrival at a disaster scene, the first assessment is **not** of victims but of the scene: Is the area safe? Are there ongoing hazards (aftershocks, fires, unstable structures, downed electrical lines, hazardous materials)? Are responders at risk of becoming casualties? Only after scene safety is assured do responders enter. Personal protective equipment (PPE) appropriate to the hazard is donned: Standard Precautions (gloves, gown, eye protection) for communicable-disease protection; respiratory protection (N95 mask or higher) if airborne pathogens are suspected; additional PPE (hazmat suits, chemical-resistant clothing) for CBRN events. A responder who becomes contaminated or injured becomes a burden, not an asset. The principle is: **'You cannot help if you are incapacitated.'** **Priority 2: Rapid Triage and Prioritization.** Upon safely accessing victims, triage begins immediately using the START system (discussed in Section 3). Every victim is assessed and colour-tagged within 60 seconds. The triage point is typically at the scene perimeter, clearly marked, and staffed by trained triage personnel. Triage is *not* treatment; it is sorting. After triage, victims are moved to treatment areas: RED victims to an acute-care/resuscitation area; YELLOW victims to a delayed-care area; GREEN victims to a minor-care area or release; BLACK victims to a comfort-care area. Triage results (colour, count by category, location) are immediately reported to the incident commander or health-sector chief so resources can be allocated appropriately. **Priority 3: Airway, Breathing, and Circulation (ABCs) in RED Victims.** RED victims have immediately life-threatening injuries. In the treatment area, the focus is the ABCs: - **Airway:** Assess for obstruction, apply jaw thrust or head-tilt chin-lift, suction secretions, insert airway adjuncts (oropharyngeal or nasopharyngeal airway), or prepare for intubation if respiratory distress is severe. In a mass-casualty setting without adequate equipment, emergency cricothyrotomy may be necessary for an obstructed airway. - **Breathing:** Assess RR and breath sounds; apply high-flow oxygen (target SpO2 > 90%); if apneic or severe respiratory distress, provide bag-valve-mask (BVM) ventilation or prepare for intubation. In a field setting, oxygen supply may be limited; prioritize ventilation support for salvageable RED victims. - **Circulation:** Control major hemorrhage (the #1 preventable cause of death in trauma): apply direct pressure, elevate the bleeding limb, apply a tourniquet above the wound if direct pressure fails, and prepare for IV resuscitation. Start IV lines (18-gauge or larger) and infuse normal saline or lactated Ringer's solution; type and cross-match for blood transfusion. Monitor for signs of shock (weak pulse, pale, cool skin, altered mental status) and address hypovolemia aggressively. **Priority 4: Decontamination (in CBRN Events).** In a CBRN event, victims are decontaminated *before* entering the treatment area (unless immediately life-threatening intervention is needed). The decontamination zone is staffed by responders in full PPE (hazmat suit, respirator, gloves). Victims remove all clothing (a critical step; 80–90% of contamination is removed with outer clothing), are irrigated with copious water (or mild soap and water for biological agents; dilute bleach solution for some biological agents), are dried, and provided clean clothing. Personal belongings are bagged and labeled for potential evidence (in case of terrorism). After decontamination, victims enter the 'cold zone' treatment area where standard precautions are adequate. This decontamination sequence prevents secondary contamination of medical staff and supplies. **Priority 5: Bleeding Control and Tourniquet Application.** Massive external hemorrhage is the #1 preventable cause of death in mass-casualty trauma. In a field or mass-casualty setting where resources are limited, tourniquet application for limb hemorrhage is the standard of care: Apply a tourniquet 2–3 inches *above* the wound (not directly over it), making it tight enough to stop all bleeding (pale limb distal to tourniquet, no audible bleeding). Write the time of application on the tourniquet so that physicians later know how long ischemia has occurred. Document tourniquet application clearly. If direct pressure fails to stop bleeding and the wound is on a limb, do *not* delay with prolonged manual pressure in a mass-casualty setting; apply a tourniquet and move to the next victim. (In a hospital setting, prolonged tourniquet time increases amputation risk; in a mass-casualty field setting, tourniquet application saves lives by allowing responders to help more victims.) **Priority 6: Prevent Secondary Disasters in Shelters and Evacuation Centres.** During response and recovery, thousands of survivors may be housed in evacuation centres (schools, barangay halls, convention centres) or temporary shelters. These congregate settings are high-risk for communicable diseases and secondary disasters if not managed. Nursing priorities: - **Safe water and sanitation:** Ensure potable water is available (boiled or treated with chlorine); establish latrines or portable toilets at least 30 meters from water sources; distribute hand-washing stations with soap at food-prep and sanitation areas; teach hand hygiene. - **Food safety:** Ensure food is sourced safely, prepared hygienically, and protected from contamination; identify any persons with food allergies or special dietary needs. - **Infection control:** Isolate any persons with respiratory symptoms or diarrhea; distribute hand sanitizer; teach respiratory hygiene (cover cough/sneeze). - **Overcrowding and ventilation:** Ensure adequate space per person (≥ 3.5 m² per person is WHO standard); provide ventilation to reduce airborne transmission; establish sleeping areas separated from sanitation areas. - **Vulnerable populations:** Ensure pregnant women, children, elderly, and persons with chronic illnesses receive appropriate care; establish childcare areas if parents are working in response activities; monitor nutritional status; distribute necessary medications (antihypertensives, diabetes medications). - **Surveillance and reporting:** Monitor for outbreaks of diarrhea, respiratory illness, or other communicable diseases; report cases to the DOH; implement control measures (isolation, treatment, vaccination if indicated). **Priority 7: Psychosocial Support and Mental Health Referral.** As discussed in Section 6, provide Psychological First Aid (Look, Listen, Link), facilitate family reunification, and refer severe psychological distress for professional care. Establish a mental health clinic or arrange regular visits by a mental health professional. **Priority 8: Documentation and Communication.** In the chaos of a disaster response, documentation may seem optional, but it is essential: - **Triage records:** Record victim identification (name, age, sex if known), triage colour, injuries identified, time, and triage officer name. Even if the record is hand-written on a tag, it provides continuity if the victim is transported to a hospital. - **Treatment records:** Document interventions performed (tourniquet applied, airway opened, IV started, medications given), time, and personnel. In a field setting, documentation may be minimal (e.g., a notecard with the victim's name, injury, and treatments), but it helps hospital staff continue care. - **Deaths:** Record victim identification, location found, presumed cause, date/time, and person performing the verification. Deaths are reported to the police and local authorities for legal documentation. - **Communication:** Incident action plans (established daily by the incident commander and agency chiefs) specify objectives, tactics, and resource needs. Nurses report to their health-sector chief; the health-sector chief reports to the incident commander. Use clear, concise communication (e.g., 'RED zone: 45 victims currently, 30 being treated, 15 awaiting transport to hospital; critical shortages: IV fluid and oxygen'). **Priority 9: Re-triage and Reassessment.** Conditions change; a RED victim may stabilize and drop to YELLOW, or a YELLOW victim may deteriorate and become RED. Triage is dynamic; re-assess victims every hour or whenever a significant change is observed. Document re-triage decisions. **Priority 10: Resource Allocation and Coordination.** Supplies are limited in a mass-casualty event. The health-sector or incident commander allocates resources based on triage priority: RED victims receive oxygen, IV fluids, tourniquets, and surgical airway equipment first; YELLOW victims share remaining resources; GREEN victims receive basic first aid. Nurses report shortages to the supply chain (logistics chief) and adapt care if resources are exhausted (e.g., if oxygen runs out, prioritize titration to hypoxic RED victims and consider other interventions for less critical victims). **Nursing Diagnoses Common in Disaster Victims** (Using NANDA Taxonomy): - Ineffective airway clearance (r/t trauma, aspiration, edema) - Ineffective breathing pattern (r/t pain, chest injury, anxiety) - Decreased cardiac output (r/t hemorrhage, shock) - Risk for infection (r/t open wounds, contamination, crowded shelters) - Acute pain (r/t trauma, wounds) - Anxiety/Fear (r/t disaster, displacement, loss) - Deficient knowledge (r/t post-disaster health, evacuation procedures) - Acute stress disorder (r/t witnessing disaster, loss, displacement) - Deficient fluid volume (r/t hemorrhage, inadequate intake in shelters) - Risk for hypothermia (r/t exposure, wet clothing) These diagnoses guide nursing interventions; in a mass-casualty setting, interventions are prioritized using Maslow's hierarchy and the disaster-response principles (greatest good for greatest number). **Ethical Considerations in Disaster Nursing:** Disaster nursing raises ethical dilemmas that differ from routine practice. For example: Should a LIMITED oxygen supply be given to a salvageable RED victim or a non-salvageable BLACK victim with a few hours of life remaining? Ethical frameworks (utilitarian, justice-based) support giving oxygen to the RED victim to maximize lives saved. In a mass-casualty setting, the nurse's duty shifts from individual beneficence (doing the most good for one patient) to public health beneficence (doing the most good for the population). Understanding and accepting this ethical framework is essential to functioning effectively in disaster response. RA 9173 and the Philippine Nursing Code of Ethics guide nurses to advocate for the greatest benefit to the public; disaster nursing is a direct application of this principle.

Disaster preparedness extends beyond hospitals and response teams to the community level. RA 10121 mandates that disaster risk reduction and management is a shared responsibility of the government, communities, and families. Nurses play a crucial role in educating families and communities on preparedness, helping them create disaster plans and go-bags, and ensuring they know when and where to evacuate. This proactive, community-focused role is central to mitigation and preparedness phases and is well-aligned with RA 9173's mandate for nurses to advance population health. **Family Disaster Preparedness Plan:** Every family should develop a written disaster plan that includes: (1) **Identification of hazards** specific to their location (Is the home in a flood-prone area? Near a fault line? Near a steep slope at risk of landslide? In a typhoon corridor? Near a chemical factory?). Understanding household hazards informs preparedness measures. (2) **Evacuation routes and meeting places.** Identify primary and secondary evacuation routes from home and from the workplace/school. Identify a safe meeting place outside the immediate area (e.g., 'If separated, we will meet at the barangay hall' or 'At the school two blocks away'). Teach children the meeting place and ensure they know how to get there. (3) **Designated safe areas/shelters.** Know the location of the nearest evacuation centre (e.g., barangay hall, school, covered court). Know the route to get there. (4) **Communication plan.** Identify an out-of-area contact person (a relative in another province) whom all family members will call after a disaster to report they are safe. Local phone networks may be overwhelmed; reaching someone outside the affected area is often easier. Share this contact's phone number with all family members. (5) **Roles and responsibilities.** Assign each family member a role (e.g., the oldest child is responsible for securing important documents; the parent is responsible for securing the go-bag). This ensures that critical tasks are not overlooked in the chaos of evacuation. **Family Go-Bag (Disaster Kit):** Each household should prepare a disaster go-bag—a pre-packed bag that can be grabbed and taken if evacuation is required. Contents include: - **Water:** 1–2 liters per person per day; at least a 3-day supply (3–6 liters for a 3-person family). Bottled water is ideal; home containers are filled from the tap (water lasts ~5 days in sealed containers). - **Food:** Non-perishable items that require no cooking or minimal water (canned goods, energy bars, biscuits, powdered milk, instant noodles, dried fruit, peanut butter). Include a manual can opener. Include foods for infants and persons with special diets. A 3-day supply is minimum. - **First-aid kit and medications:** Bandages, antiseptic, pain relievers, anti-diarrheal (loperamide), antihistamine, antacid, antibiotic ointment, tweezers, scissors, gloves. Include prescription medications (enough for 7 days), inhalers (for asthma), and glucose tablets (for diabetes). - **Flashlight and batteries:** A hand-crank or rechargeable flashlight is ideal (lasts indefinitely). Include extra batteries; batteries lose charge over time, so check annually. - **Whistle:** A plastic whistle can signal for help; teach all family members (including children) that three blasts is the universal distress signal. - **Personal documents:** Photocopies of birth certificates, marriage certificates, property deeds, insurance documents, bank account information, medical records, and ID cards. Store copies in a waterproof bag. - **Cash (small denominations):** If ATMs are disabled, cash is essential. Include coins for payphones if cell towers are down. - **Torch/candles and matches:** Waterproof matches or a lighter. - **Change of clothes and sturdy shoes:** Include a change for each family member; comfortable walking shoes are essential for evacuation on foot. - **Toiletries:** Soap, toothbrush, toothpaste, feminine hygiene products, diapers, wipes (if infants in the family). - **Blanket or sleeping bag:** If displaced to an evacuation centre without shelter provided. - **Photos of family members:** Helps identify persons and reunite families if separated. - **Contact information:** Written list of emergency contact numbers (cell networks may be down); family members' names and out-of-area contact details. - **Medications and medical equipment:** Prescription medications (7-day supply), inhalers, glucose meters, insulin, EpiPens, any other medical equipment. - **Pet care items:** If the family has pets, include pet food, water, and carrier/leash. Include pet identification and vaccination records. The go-bag should be stored in a clearly labeled, easily accessible location (e.g., by the front door, in the bedroom); every family member should know where it is. Items should be reviewed and restocked annually (check expiration dates on food and medications, rotate water, update documents and contact information). **Community-Level Preparedness Education:** Nurses conduct community education on disaster preparedness. Topics include: (1) **Hazard identification and personal risk assessment** – teach community members to identify hazards specific to their location and understand their personal risk. A community in Negros Occidental may focus on typhoon preparedness; a community near Mt. Mayon may focus on volcanic hazards; a community in Quezon City may focus on earthquake preparedness and building collapse risk. (2) **Early warning signs and warning systems** – teach the community to recognize early warning signs (heavy rain and wind for typhoons, ground shaking for earthquakes, ashfall for volcanic eruptions) and to understand the community's warning system (sirens, text alerts, radio announcements). Teach the meaning of warnings: a 'yellow alert' may mean stay alert and prepare to evacuate; an 'orange alert' means evacuation is imminent; a 'red alert' means evacuate immediately. (3) **Evacuation procedures** – conduct drills at schools and in the barangay; teach the route to evacuation centres, what to bring (go-bag), and how to help vulnerable persons (elderly, children, pregnant women, persons with disabilities). (4) **Post-disaster health and safety** – teach families to: boil water or use chlorine tablets if water safety is uncertain; practice hand hygiene and sanitation after a disaster (rates of diarrhea and waterborne disease spike post-disaster); recognize symptoms of communicable diseases and when to seek care; prevent mosquito breeding (dengue and leptospirosis risk after floods); and avoid contaminated areas and hazardous materials. (5) **First aid basics** – teach CPR, wound care, and tourniquet application so community members can provide immediate help to injured persons before responders arrive. (6) **Psychosocial impacts and coping** – normalize stress reactions after a disaster; teach basic coping skills (talking with family and friends, physical activity, maintaining routines); provide information on where to access mental health support. **Vulnerable Populations:** Special attention in preparedness is needed for: - **Pregnant women and lactating mothers:** Ensure access to prenatal/postnatal care, nutrition, and privacy for nursing; establish safe delivery protocols in evacuation centres if needed. - **Children:** Involve children in disaster drills and planning (age-appropriate); teach them evacuation routes and meeting places; establish childcare in evacuation centres so parents can participate in response. - **Elderly persons:** Ensure physical accessibility to shelters; provide mobility aids if needed; store medications; connect them with social support and regular check-ins (social isolation is a risk in evacuation centres). - **Persons with disabilities:** Ensure mobility aids and medications are available; provide accessible shelters with ramps and accessible sanitation; assign buddies to assist if needed. - **Persons with chronic illnesses:** Ensure prescription medications are stocked; establish a system for regular clinic visits in shelters; provide monitoring (blood pressure checks for hypertensive patients, blood glucose monitoring for diabetics). - **Orphans and unaccompanied children:** Establish a system to identify and protect unaccompanied children; facilitate family tracing; assign responsible adults as temporary guardians. **Local Government and Barangay Role:** The barangay is the primary unit of disaster risk reduction and management in the Philippines. A disaster-prepared barangay has: (1) **Barangay Disaster Risk Reduction and Management (BDRRM) Committee** – includes the barangay captain, health worker, teacher, volunteer rescuer, and community representatives; meets monthly to update the barangay disaster plan. (2) **Updated Barangay Disaster Plan** – revised annually; includes hazard map, evacuation routes and shelters, resource inventory (go-bags, first-aid kits, flashlights), communication chain, volunteer roster and training schedule, and recovery protocols. (3) **Trained volunteers** – the barangay trains volunteer rescuers (CERT—Community Emergency Response Team) in basic triage, first aid, search and rescue, and fire suppression. Annual refresher training ensures competency. (4) **Pre-positioned supplies** – the barangay stockpiles emergency supplies (tents, water containers, food, first-aid kits, flashlights, batteries, blankets) in a central location; items are checked and rotated regularly. (5) **Warning system** – establishes a communication system (sirens, text alerts via barangay hotline, radio announcements) to alert residents to approaching hazards. Community members are taught what each alert level means and how to respond. (6) **Regular drills and exercises** – conducts quarterly evacuation drills (for typhoon-prone areas) or annual drills (for other areas); involves residents, tests communication systems, and identifies gaps in planning. (7) **Post-disaster assessment and recovery** – after a disaster, the barangay documents damage, coordinates with municipal authorities, provides relief assistance, and supports long-term recovery. (8) **Partnership with health facilities** – the barangay health worker (BHW) and rural health midwife (RHM) coordinate with the rural health unit (RHU) and nearest hospital to ensure disaster response capacity. **Nurse's Role in Community Preparedness:** - Participate in the BDRRM Committee; advocate for health-sector priorities in disaster planning. - Conduct hazard-vulnerability analysis; identify risks to the health facility and the community. - Train community volunteers (BHWs, CERT members) in triage, first aid, basic life support, and infection control. - Lead community education on disaster preparedness, family planning, go-bag contents, evacuation procedures, and post-disaster health. - Supervise preparation and maintenance of the barangay's emergency supply stockpile. - Participate in drills and exercises; provide feedback to improve future response. - Document lessons learned post-disaster and feed them back into the BDRRM plan (continuous improvement). **Nurse's Role in Family Education:** - During routine clinic visits (prenatal, child health, chronic disease management), ask families about their disaster preparedness and provide guidance if gaps are identified. - Teach families to develop disaster plans and go-bags; provide checklists and written materials. - Answer questions about post-disaster health risks (water safety, communicable diseases, mental health). - Model disaster preparedness in your own family; be a credible advocate. - Use opportunities (school events, barangay fiestas, radio programs) to reach wider audiences with preparedness messages.

The recovery phase begins once the acute response subsides, but health risks persist for weeks to months. The nurse's role extends to preventing secondary health disasters—outbreaks of communicable disease, malnutrition, and mental health crises that can occur in crowded, unsanitary shelters or displaced communities. Understanding the epidemiology of post-disaster health threats and the public-health interventions to prevent them is essential for NLE preparation. **Water and Sanitation:** Post-disaster, water supply systems may be contaminated (flooding, sewage intrusion, chemical contamination) or disrupted (pumps non-functional, pipes damaged). Unsafe water is the primary risk factor for outbreaks of diarrhea, typhoid, cholera, and dysentery. Nursing priorities: - **Water safety assessment:** Test or assume water is unsafe after a disaster. Sources of safe water: bottled water (verified sealed/unopened), boiled water (boil for 1 minute at a rolling boil), or treated water (add 2 drops of bleach per liter, let sit 30 minutes). Teach families and shelter staff these methods. - **Sanitation facilities:** Establish pit latrines or portable toilets at least 30 meters downslope from water sources. Ensure adequate number (1 toilet per 20 persons is the minimum standard). Provide hand-washing stations with soap and water near toilets and food-preparation areas. - **Hygiene education:** Teach hand hygiene (wash hands after using toilet, before eating, before food preparation); teach respiratory hygiene (cover cough/sneeze with elbow). Distribute hand sanitizer where water is limited. - **Water quantity monitoring:** Ensure adequate water is available (minimum 7.5 liters per person per day: 2.5 liters for drinking/cooking, 5 liters for washing). If water supply is inadequate, ration carefully and prioritize drinking water. **Vector-Borne Disease Prevention:** Stagnant water and debris from floods create breeding sites for disease vectors (mosquitoes for dengue, leptospirosis; rats for leptospirosis and plague; snails for schistosomiasis). Nursing priorities: - **Mosquito-breeding prevention:** Clear stagnant water daily (standing water in containers, debris, coconut shells). Use bed nets (particularly in the evening when Aedes mosquitoes are active); spray with insecticide if available. Teach community members to empty water containers, cover water storage, and drain any standing water. - **Leptospirosis prevention:** Educate families to avoid contact with floodwater (cuts/abrasions allow entry of Leptospira). Provide protective equipment (boots, gloves) to those cleaning flooded homes. Treat water by boiling or bleach before use. - **Rat control:** Clean up debris and food scraps (attract rats). Set traps in shelters. Maintain cleanliness to reduce harbourage for rodents. - **Surveillance and case detection:** Ask shelter residents about fever, headache, muscle pain, and rash (dengue); fever, chills, headache, body ache, nausea, and jaundice (leptospirosis). Refer suspected cases for testing and treatment. Educate residents on symptoms and when to seek care. **Food Safety and Nutrition:** Malnutrition and foodborne illness are risks in shelters where food is limited and preparation is unsanitary. Nursing priorities: - **Food sourcing and handling:** Ensure food is obtained from safe, verified sources (not salvaged from flooded areas). Food must be prepared in clean kitchens, with staff trained on hand hygiene and sanitation. Raw foods (vegetables, meat) must be washed and cooked thoroughly. Avoid foods likely to spoil (milk, cream, mayonnaise) in the absence of refrigeration. - **Special populations:** Pregnant women and young children have increased nutritional needs. Provide micronutrient supplementation (vitamin A, iron, folic acid, zinc). Breastfeeding mothers should continue breastfeeding (safe and does not require fuel or water for preparation); provide caloric supplements if available. - **Nutrition monitoring:** Monitor weight and height of children; watch for signs of malnutrition (wasting, stunting, edema). Refer severely malnourished children for intensive nutrition support. **Infectious Disease Surveillance and Control:** Shelters are high-transmission environments for respiratory and gastrointestinal infections. The nurse conducts active surveillance (regularly assessing residents for symptoms) and implements control measures. - **Acute respiratory infection (ARI):** Common after disasters due to crowding, cold/wet conditions, and stress. Case detection: ask about cough, runny nose, sore throat, fever. Isolate respiratory cases in separate area; promote hand hygiene and respiratory hygiene (cover cough). Provide oral rehydration solution (ORS) and paracetamol. Refer severe cases (difficulty breathing, stridor, lethargy) for immediate care. - **Acute watery diarrhea (AWD):** Common after flooding and poor sanitation. Case detection: monitor for diarrhea (≥ 3 loose stools per day). Provide ORS and zinc supplementation. Isolate cases; improve water and sanitation. Refer severe dehydration (lethargy, weak pulse, poor skin turgor) for IV rehydration. - **Dysentery (bloody diarrhea):** Caused by Shigella or Entamoeba; higher mortality than watery diarrhea. Case detection: ask about bloody stool. Refer for antibiotic treatment (ciprofloxacin or azithromycin for bacterial dysentery). Implement strict sanitation (disinfect latrines, hand hygiene). - **Vaccine-preventable diseases:** Risk of measles, polio, pertussis in crowded conditions. Check vaccination status of children; provide catch-up vaccination if indicated. - **Communicable disease reporting:** Report suspected cases of cholera, typhoid, plague, dengue, measles, polio, and other notifiable diseases to the DOH immediately. This triggers outbreak response (case investigation, contact tracing, isolation, treatment, vaccination campaigns if needed). **Reproductive and Sexual Health:** Displaced women lose access to reproductive health services. Pregnancy complications (preeclampsia, infection) and unsafe abortion are risks. Nursing priorities: - **Antenatal and postnatal care:** Establish clinic services in shelters; screen for preeclampsia (blood pressure, proteinuria), anemia (paleness, shortness of breath), and infection. Provide iron and folic acid supplementation. - **Skilled birth attendance:** Ensure pregnant women have access to a midwife or health professional for delivery. If delivery in shelter is imminent and transport to hospital is impossible, assist with delivery using clean delivery kit (clean blade, clean gloves, clean cloths, cord ties, antiseptic). - **Family planning:** Provide contraception information and access to prevent unintended pregnancies during displacement. - **Sexual violence prevention:** Displaced persons, particularly women and girls, are at risk of sexual violence. Establish safety protocols in shelters (separate sleeping areas, adequate lighting, community patrols). Provide trauma-informed care to survivors of sexual violence; refer for medical evaluation, STI testing, and emergency contraception if indicated. Refer for psychological support. **Non-Communicable Disease Management:** Persons with chronic illnesses (hypertension, diabetes, asthma, heart disease) lose access to medications and routine monitoring in displacement. Risk of complications (hypertensive crisis, diabetic ketoacidosis, asthma exacerbation) increases. Nursing priorities: - **Medication access:** Establish a system to distribute essential medications to persons with chronic illnesses. Maintain a registry of residents with chronic illnesses and their medication needs; liaise with the DOH and NGOs to secure medication supplies. - **Clinical monitoring:** Conduct regular clinic sessions in shelters; monitor blood pressure (hypertensives), blood glucose (diabetics), peak flow (asthmatic). - **Health education:** Teach residents to continue taking medications, even during displacement; explain the risks of stopping antihypertensives or diabetes medications. Teach recognition of warning signs (chest pain, severe headache, difficulty breathing) and when to seek emergency care. **Environmental Health and Hazard Assessment:** Post-disaster, environmental hazards may remain: contaminated sites, hazardous materials, unsafe structures. Nursing priorities: - **Shelter safety assessment:** Assess structures used as shelters for stability (are they at risk of collapse in aftershocks? Are roofs intact? Is there adequate ventilation?). Recommend relocation if shelters are unsafe. - **Hazard awareness:** Educate residents to avoid contaminated areas (flooded sites with sewage, areas exposed to chemical spills, collapsed buildings with asbestos or lead). - **Debris management:** Coordinate safe removal of debris; debris can harbor disease vectors, sharp objects, and hazardous materials. **Mental Health Support Continuity:** As noted in Section 6, psychological impacts persist long after the acute phase. The nurse ensures continuity of mental health support: - **Ongoing PFA and counseling:** Continue Psychological First Aid in shelters; provide grief counseling for those who lost loved ones. - **Professional mental health services:** Arrange regular visits by psychiatrists or psychologists; provide medications for depression and anxiety if prescribed. - **Reintegration support:** As residents return to homes or permanent shelter, maintain mental health support; identify barriers to recovery (loss of home, loss of livelihood) and connect with recovery assistance programs. - **Identification and treatment of PTSD and depression:** Screen residents who experienced trauma or loss for PTSD and depression; refer for specialized treatment if symptoms persist beyond 3 months. **Documentation and Reporting:** Post-disaster surveillance data (cases of diarrhea, respiratory infection, dengue, etc., by location and date) are compiled and reported to the DOH, which uses this data for outbreak detection, resource allocation, and national surveillance. **Recovery Support for Livelihood and Social Reintegration:** While primarily outside nursing scope, nurses advocate for and connect survivors with livelihood support programs (vocational training, microcredit, employment assistance), psychosocial support, and community reintegration programs. Communities recover most fully when residents regain economic security and social connection; nurses' advocacy for these broader support measures contributes to holistic recovery.
