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

Exam Tips

• NLE questions on disaster definitions typically test whether you understand the 'overwhelmed resources' concept and the shift in care goals.
• When a question asks about disaster GOALS or PRIORITIES, the answer is always 'greatest good for the greatest number' — not individual patient advocacy.
• Philippine context: Know at least 3 examples of natural disasters relevant to the Philippines (typhoons, earthquakes, volcanic eruptions) and their associated health risks.

Key Points

• A DISASTER is any event that OVERWHELMS local resources and capacity, causing damage, destruction, and human suffering.
• NATURAL disasters: typhoons (e.g., Typhoon Yolanda/Hainan 2013), earthquakes (e.g., 2019 Cotabato), volcanic eruptions (e.g., Taal 2020), floods, tsunamis, landslides, droughts.
• MAN-MADE (technological/human-induced) disasters: industrial accidents, chemical spills, fires, transportation crashes, structural collapse, terrorism, armed conflict.
• CRITICAL CONCEPTUAL SHIFT — The goal of care changes in disasters: Routine nursing care = greatest good for the INDIVIDUAL patient. Disaster nursing care = greatest good for the GREATEST NUMBER (utilitarian/population focus).
• This shift means the most severely injured patient is NOT always treated first — resources are allocated to save the most lives overall.
• The Philippines experiences an average of 20 typhoons per year, making disaster nursing a core NCM competency aligned with the national health agenda.

1. Core Concepts: What is a Disaster?

Common Mistakes

• Confusing 'disaster' with any medical emergency — remember, the defining feature is that resources are OVERWHELMED, not just the severity of injury.
• Forgetting that the goal shifts from individual to population in disaster settings — applying routine triage logic (most injured = treated first) in a mass-casualty scenario is WRONG.
• Mixing up natural and man-made disaster categories — CBRN events are man-made, not natural.

Exam Tips

• NLE questions often give a nursing activity and ask which phase it belongs to. Key rule: if it PREVENTS or REDUCES impact → Mitigation; if it PLANS/TRAINS/STOCKPILES → Preparedness; if it RESPONDS NOW → Response; if it REBUILDS/RESTORES → Recovery.
• Remember: Recovery is the LONGEST phase — this is frequently tested.
• Philippine nurses are expected to participate in all four phases at the community level — barangay disaster drills (preparedness), flood-control advocacy (mitigation), staffing evacuation centers (response), and post-disaster health surveillance (recovery).

Key Points

• Disaster management is a CONTINUOUS CYCLE — all four phases feed back into each other.
• PHASE 1 — MITIGATION: Actions BEFORE a disaster to PREVENT it or REDUCE its impact. Mnemonic: 'M = Make it Less Likely or Less Bad.'
• Mitigation examples: hazard mapping, building codes, structural reinforcement, land-use planning, flood control projects, mangrove reforestation, hazard-vulnerability analysis of health facilities.
• PHASE 2 — PREPAREDNESS: Planning and readiness BEFORE a disaster so response is EFFECTIVE. Mnemonic: 'P = Plan and Prepare.'
• Preparedness examples: writing and testing disaster plans, drills and simulations, training responders, stockpiling supplies and medications, establishing warning systems and communication chains, preparing family 'go-bags.'
• PHASE 3 — RESPONSE: Actions DURING and IMMEDIATELY AFTER the disaster to SAVE LIVES and prevent further harm. Mnemonic: 'R = React Now.'
• Response examples: activating the disaster plan, search and rescue, START triage, emergency treatment, evacuation, establishing shelters, meeting immediate survival needs (water, food, sanitation, safety).
• PHASE 4 — RECOVERY: Actions AFTER the response to RESTORE the community — the LONGEST phase. Mnemonic: 'R = Rebuild and Restore.'
• Recovery examples: rebuilding infrastructure, restoring health services, ongoing physical and mental health care, disease surveillance, evaluation of the response to improve future mitigation.
• KEY SEQUENCE: Mitigation → Preparedness → Response → Recovery → (feeds back to Mitigation). Mitigation and Preparedness are PRE-disaster; Response is DURING/IMMEDIATELY AFTER; Recovery is AFTER and is the LONGEST phase.
• Lessons learned in Recovery feed back into Mitigation and Preparedness, making this a continuous improvement cycle.

Section Title

2. The Four Phases of Disaster Management

Common Mistakes

• Confusing MITIGATION and PREPAREDNESS — both are pre-disaster, but mitigation PREVENTS/REDUCES impact while preparedness ensures READINESS for response.
• Stating that the RESPONSE phase is the longest — it is actually RECOVERY.
• Forgetting that RECOVERY feeds back to MITIGATION — the cycle is continuous, not linear.
• Placing 'stockpiling supplies' in the response phase — it belongs in PREPAREDNESS.
• Placing 'hazard mapping' in preparedness — it is a MITIGATION activity.

Exam Tips

• NLE scenario questions on triage: Always apply START in order — Ambulation → Respirations → Perfusion → Mental Status.
• The cutoff numbers to memorize: RR > 30 = RED; Cap refill > 2 seconds = RED; Cannot follow commands = RED.
• When asked 'which patient do you treat first in MCI?', the answer is RED (immediate/salvageable) — NOT the most severely injured (black).
• A victim who is not breathing but BEGINS breathing after airway repositioning = RED (not black) — this distinction is frequently tested.
• Remember: In routine ER, most critical patient is treated first. In MCI disaster, most salvageable RED patient is treated first — disaster reverses routine nursing prioritization for Black-tagged victims.

Key Points

• TRIAGE = sorting victims to allocate limited resources for maximum lives saved. In MCI, triage determines who is treated first.
• START = Simple Triage And Rapid Treatment — the standard adult mass-casualty triage system. Each victim assessed in UNDER 60 SECONDS.
• START assesses THREE parameters in order: R-P-M = Respirations, Perfusion, Mental Status.
• STEP 1 — AMBULATION: Call out for anyone who can WALK to move to a safe area. All who walk → tag GREEN (minor). Proceed to assess non-walkers.
• STEP 2 — RESPIRATIONS: Is the victim breathing? If NO → open/reposition airway. If still NOT breathing after airway opening → BLACK (deceased/expectant). If breathing BEGINS ONLY after airway maneuver, OR respirations > 30/min → RED (immediate). If respirations are ≤ 30/min → proceed to Perfusion.
• STEP 3 — PERFUSION: Check RADIAL PULSE or CAPILLARY REFILL. If radial pulse is ABSENT OR capillary refill > 2 seconds → RED (immediate) — control major bleeding. If perfusion is ADEQUATE → proceed to Mental Status.
• STEP 4 — MENTAL STATUS: Give a simple command ('Squeeze my hand' / 'Open your eyes'). If victim CANNOT follow simple commands → RED (immediate). If victim CAN follow commands → YELLOW (delayed).
• RED (Priority 1 — Immediate): Life-threatening BUT SALVAGEABLE injuries needing intervention NOW. Examples: airway compromise, uncontrolled bleeding, shock, RR > 30, absent radial pulse, cap refill > 2 sec, altered mental status. TREATED FIRST.
• YELLOW (Priority 2 — Delayed): Serious but STABLE injuries — can wait a short time without threat to life or limb. Examples: stable fractures, moderate burns without airway involvement.
• GREEN (Priority 3 — Minor): 'Walking wounded' — minor injuries, can wait longest. May assist with minor tasks.
• BLACK (Priority 4 — Expectant/Deceased): Dead, OR injuries so severe survival is unlikely even with maximal care. In MCI: comfort care only, NO treatment resources expended here so salvageable victims can be saved.
• CRITICAL REVERSAL OF INSTINCT: The most severely injured (BLACK) are NOT treated first. RED (salvageable) victims are the true first priority for treatment. Black tag = expectant = accept and move on.
• Re-triage frequently — conditions change! A YELLOW can deteriorate to RED, a RED can deteriorate to BLACK.

3. Mass-Casualty Triage: The START System

Common Mistakes

• Treating the BLACK (most severely injured) patient first — this is WRONG in MCI; RED (salvageable) patients are treated first.
• Confusing YELLOW and RED — Yellow is STABLE and can wait; Red is LIFE-THREATENING and needs intervention NOW.
• Forgetting to open the airway BEFORE tagging a non-breathing victim as BLACK — you must attempt airway repositioning first; if they breathe after → RED, not BLACK.
• Using capillary refill INSTEAD of radial pulse without noting both are acceptable — the NLE may test either.
• Forgetting that walking victims are tagged GREEN BEFORE assessing non-walkers — this is the FIRST step of START.
• Stating that RE-TRIAGE is not needed — conditions change, so repeated triage is essential.
• Applying pediatric triage criteria (JumpSTART) to adults — START is for adults; JumpSTART has different parameters for children (e.g., 5 rescue breaths before tagging black).

Exam Tips

• NLE CBRN questions frequently test: (1) agent identification by symptoms, (2) correct antidote, (3) correct sequence (PPE → decontaminate → treat).
• Nerve agent question pattern: SLUDGE symptoms + miosis → answer = atropine + pralidoxime.
• Radiation question pattern: nuclear/radiological event + thyroid protection → answer = potassium iodide (KI).
• Radiation protection question → always answer: TIME, DISTANCE, SHIELDING.
• Biological agent clue: DELAYED onset, unusual illness clusters, public health reporting required — think incubation period.
• The sequence for ANY CBRN response: Scene safety + PPE → Decontaminate victims → Treat → Report within incident command.

Key Points

• CBRN = Chemical, Biological, Radiological, Nuclear — deliberate or accidental hazardous agent releases producing mass casualties requiring specialized protective and decontamination measures.
• OVERARCHING CBRN RULE #1: PROTECT THE RESPONDER FIRST — wear PPE before approaching. An incapacitated nurse helps NO ONE.
• OVERARCHING CBRN RULE #2: DECONTAMINATE BEFORE THE VICTIM ENTERS THE TREATMENT AREA — prevents secondary contamination of staff and facility.
• OVERARCHING CBRN RULE #3: Follow the INCIDENT COMMAND STRUCTURE — do not act independently.
• CHEMICAL agents: Rapid onset. Types include nerve agents (sarin, VX), blister/vesicant agents (mustard gas), choking agents (chlorine, phosgene), blood agents (cyanide). Nerve agents: signs = SLUDGE (Salivation, Lacrimation, Urination, Defecation, GI distress, Emesis) plus miosis and seizures. ANTIDOTE for nerve agents = ATROPINE (blocks cholinergic effects) + PRALIDOXIME/2-PAM (reactivates acetylcholinesterase — give EARLY before 'aging'). Priority: DECONTAMINATION (remove all clothing — removes 70-80% of contamination, copious water irrigation) then antidote.
• BIOLOGICAL agents: Anthrax, plague, smallpox, botulism, tularemia. Onset is DELAYED (incubation period), so recognition often comes from surveillance of unusual illness clusters — 'epidemiological clue.' Priority: ISOLATION, strict infection control, prophylaxis/vaccination, and MANDATORY PUBLIC HEALTH REPORTING (DOH notification). Smallpox: person-to-person transmission — airborne + contact precautions.
• RADIOLOGICAL events: Dispersal of radioactive material (e.g., 'dirty bomb' = conventional explosive + radioactive material). Causes contamination of people and environment. Priority: decontamination; monitor for Acute Radiation Syndrome (ARS).
• NUCLEAR events: Nuclear detonation causing blast, thermal, AND radiation injury. Priorities: Treat life-threatening CONVENTIONAL injuries FIRST (blast, burns), then radiation effects. POTASSIUM IODIDE (KI) protects the thyroid from radioactive iodine uptake — give early.
• RADIATION PROTECTION TRIAD: TIME (minimize time of exposure), DISTANCE (maximize distance from source — inverse square law), SHIELDING (use physical barriers like lead, concrete, or even dense materials).
• Decontamination GENERALLY precedes definitive treatment EXCEPT for immediately life-threatening emergencies (airway, major hemorrhage).
• PPE selection depends on agent type — highest protection (Level A or B) for unknown chemical agents; appropriate respiratory and contact precautions for biological agents.

4. CBRN Events: Chemical, Biological, Radiological, Nuclear

Common Mistakes

• Entering a CBRN scene WITHOUT PPE — personal protection is the FIRST priority; a contaminated nurse is a second casualty.
• Treating victims before decontamination — this contaminates the treatment area and staff (secondary contamination).
• Using atropine ALONE for nerve agents — pralidoxime (2-PAM) must also be given EARLY before 'aging' of acetylcholinesterase occurs.
• Confusing KI (for radioactive iodine) with a general radiation antidote — KI is thyroid-specific and not protective for other radiation types.
• Forgetting that biological agents have a DELAYED onset — presenting clusters of unusual illness are the clue, not immediate mass casualties.
• Mixing up the CBRN categories — knowing which category anthrax (biological), sarin (chemical), dirty bomb (radiological), and nuclear detonation belong to is essential.

Exam Tips

• NLE legislative questions: RA 10121 → NDRRMC → DRRM (risk reduction focus). This is a common pattern.
• When asked which law governs Philippine disaster management, the answer is RA 10121.
• For community health questions about disaster: think barangay plans, evacuation centers, vulnerable populations, communicable disease surveillance.
• Connect RA 9173 to professional accountability in disasters — nurses have a legal and ethical obligation to respond.

Key Points

• RA 10121 = Philippine Disaster Risk Reduction and Management Act of 2010 — the primary law governing disaster management in the Philippines.
• RA 10121 SHIFTED policy from reactive DISASTER RESPONSE to proactive DISASTER RISK REDUCTION AND MANAGEMENT (DRRM).
• RA 10121 created the NATIONAL DISASTER RISK REDUCTION AND MANAGEMENT COUNCIL (NDRRMC) — the highest national body for DRRM.
• RA 10121 mandates DRRM councils and offices at ALL levels: national (NDRRMC), regional (RDRRMC), provincial, city/municipal (C/MDRRMC), and BARANGAY (BDRRMC) — a whole-of-government and whole-of-society approach.
• The BARANGAY level is critical in Philippine context — barangay disaster plans, evacuation centers, early-warning systems, and community drills are front-line preparedness.
• INCIDENT COMMAND SYSTEM (ICS): Standardized command-and-control structure for coordinating multiple responding agencies during a disaster — prevents confusion and duplication. The ICS establishes a clear chain of command, unified management, and designated roles.
• DOH ROLE: Leads the HEALTH-SECTOR response through Health Emergency Management (HEM) systems and pre-positioned response teams (e.g., HEARS — Health Emergency Assessment and Response System).
• NURSE ROLES across all four phases: Mitigation (hazard-vulnerability assessment of health facilities), Preparedness (disaster plan participation, drills, family education), Response (triage, emergency care, evacuation center staffing), Recovery (surveillance, mental health care, community rehabilitation).
• At EVACUATION CENTERS, priority health concerns: communicable disease surveillance (leptospirosis, dengue, acute watery diarrhea, measles), safe water and sanitation, infection control, and care of vulnerable groups (children, pregnant women, elderly, persons with disabilities, chronically ill).
• Note: RA 9173 (Philippine Nursing Act of 2002) defines the scope of nursing practice — disaster nursing falls within the community health nursing scope, with nurses obligated to respond in public health emergencies as part of professional accountability.

5. Philippine DRRM Framework: RA 10121

Common Mistakes

• Confusing RA 10121 with RA 9173 — RA 10121 is the DRRM Act; RA 9173 is the Nursing Practice Act.
• Stating that NDRRMC handles only national disasters — it coordinates ALL levels of DRRM in the Philippines.
• Forgetting that BARANGAY-level DRRM (BDRRMC) is part of RA 10121's mandate — community-level readiness is explicitly legislated.
• Overlooking communicable disease risks in evacuation centers — leptospirosis, dengue, and diarrheal diseases are major post-disaster health threats in the Philippine context.

Exam Tips

• NLE PFA questions: The answer is always LOOK, LISTEN, LINK — not forced debriefing, not therapy.
• If asked what to do first for a disaster survivor, ensure SAFETY and BASIC NEEDS are met before psychological support (Maslow prioritization).
• If asked about the FIVE PFA principles, remember: Safety, Calming, Self-efficacy, Connectedness, Hope.
• PFA is for IMMEDIATE aftermath — if symptoms persist (> 1 month, functional impairment), refer for PTSD evaluation.
• Distinguish PFA (for nurses/non-mental health responders, immediate) from formal psychiatric intervention (for mental health professionals, ongoing).

Key Points

• Disasters cause PSYCHOLOGICAL as well as physical harm — acute stress reactions and post-traumatic stress disorder (PTSD) are common sequelae.
• PFA = Psychological First Aid — the recommended IMMEDIATE psychosocial support for disaster survivors. It is NOT formal therapy and does NOT require mental health credentials.
• PFA does NOT force people to talk about the trauma — 'critical incident debriefing' (forcing recounting of trauma) is NO LONGER recommended as a routine early intervention.
• The core PFA framework = LOOK, LISTEN, LINK (3 L's):
• LOOK: Observe for safety, identify people with urgent needs, identify those in serious distress.
• LISTEN: Approach those who need support; ask about needs and concerns; listen actively; help people feel calm WITHOUT pressuring them to recount trauma.
• LINK: Connect people with basic needs and services; provide accurate information; reunite families; refer those with severe reactions to professional mental health care.
• The FIVE PRINCIPLES of PFA (Psychological First Aid): Promote SAFETY, CALMING, SELF- and COMMUNITY-EFFICACY, CONNECTEDNESS, and HOPE.
• PFA PRIORITY ORDER based on Maslow: Meet PHYSIOLOGICAL needs first (water, food, shelter, safety — basic survival), then address psychological support, then link to higher-level services.
• PFA is for EVERYONE — survivors, family members of victims, even responders who may experience vicarious trauma and burnout.
• RESPONDER SELF-CARE: Fatigue, burnout, and vicarious trauma must be actively managed — shift rotations, peer support, debriefing for responders (structured, voluntary, not forced).
• Refer to professional mental health care (psychiatrist, psychologist, mental health nurse) if: severe dissociation, suicidal ideation, persistent inability to function, severe PTSD symptoms.
• Provide ACCURATE INFORMATION — rumor control is a core PFA function; misinformation increases panic and psychological harm.

6. Psychological First Aid (PFA)

Common Mistakes

• Describing PFA as psychotherapy or counseling — PFA is IMMEDIATE SUPPORT, not formal therapy.
• Recommending routine 'critical incident debriefing' (forcing trauma recounting) — this is NO LONGER recommended and may be harmful.
• Prioritizing psychological support BEFORE meeting physiological needs — Maslow's hierarchy applies; safety and basic needs come FIRST.
• Forgetting that LOOK, LISTEN, LINK is the PFA framework — some students confuse it with other nursing frameworks.
• Ignoring RESPONDER mental health — vicarious trauma and burnout affect nurses and must be managed.

Exam Tips

• For NLE questions on nursing priority in MCI: Scene safety → Triage → RED patients → ABC → Decontaminate (CBRN) → PFA.
• For NLE questions on family/patient teaching: go-bag, evacuation routes, boiling water, leptospirosis prevention, and mental health normalization are high-yield.
• NANDA diagnoses in disaster: Post-Trauma Syndrome and Risk for Infection are commonly tested.
• Philippine-specific disasters frequently appear in NLE case scenarios — know typhoon-related (leptospirosis, dengue after floods), earthquake-related (crush injuries, building collapse), and volcanic eruption-related (ash inhalation, lahar) health threats.

Key Points

• NURSING PRIORITY SEQUENCE IN DISASTER: (1) Scene safety + PPE first, (2) Triage using START, (3) Treat RED/immediate-salvageable first: address Airway, Breathing, Circulation (ABC), major hemorrhage, (4) CBRN: Decontaminate before treatment (except life-threatening emergency), (5) Prevent secondary disasters in shelters, (6) Provide PFA, (7) Document and communicate within ICS.
• NANDA-based nursing diagnoses applicable in disaster: Impaired Gas Exchange (inhalation injury), Deficient Fluid Volume (hemorrhage, dehydration), Risk for Infection (shelter conditions, flood exposure), Acute Confusion (blast injury, chemical exposure), Post-Trauma Syndrome (survivors of disasters), Anxiety, Fear, Ineffective Community Coping.
• MASLOW PRIORITIZATION IN DISASTER: Physiological needs (airway, breathing, circulation, hemorrhage control, hydration, shelter, food) → Safety (evacuation, decontamination, infection control) → Social/Psychological (PFA, family reunification) → Esteem/Self-actualization (community recovery, empowerment).
• SHELTER/EVACUATION CENTER NURSING: Safe water (boil or treat), sanitation and waste management, infection control (handwashing, respiratory precautions), communicable disease surveillance (leptospirosis, dengue, measles, acute watery diarrhea), care of vulnerable groups.
• GO-BAG CONTENTS to teach: Water (at least 3 liters per person per day), non-perishable food, essential medications (maintenance meds for 7 days), flashlight + batteries, first-aid kit, whistle (signal for help), waterproof pouch with copies of important documents (IDs, health records, land titles), cash, mobile phone with charger/power bank, family communication and meeting plan.
• POST-DISASTER HEALTH TEACHING: Boil or chemically treat all water (leptospirosis, cholera, typhoid risk after floods), strict hand hygiene, eliminate standing water to prevent mosquito breeding (dengue), clean wounds thoroughly and seek care for contaminated wounds (leptospirosis entry), recognize warning signs of illness and when to seek care.
• MENTAL HEALTH TEACHING: Normalize stress reactions after disasters (sadness, fear, sleep disturbance, irritability are normal short-term responses), teach basic coping (maintain routine, social support, limit media exposure), provide mental health referral information, use PFA principles.
• DOCUMENTATION in disaster: Record triage tags assigned, treatments given, victim identification, time of treatment, medications administered, and any decontamination performed — supports continuity of care and ICS reporting.

7. Nursing Management and Patient/Family Teaching

Common Mistakes

• Forgetting SCENE SAFETY and PPE as the FIRST nursing action in any disaster/CBRN scenario.
• Applying routine ABC priority without considering triage TAGS — in MCI, triage determines who receives ABC care first.
• Teaching only the go-bag contents without including the family COMMUNICATION AND MEETING PLAN — reunification planning is equally important.
• Neglecting vulnerable groups (children, pregnant women, elderly, disabled, chronically ill) in evacuation center care — these groups have priority needs.
• Forgetting leptospirosis as a major post-flood health threat in the Philippines — wading in floodwater, wound care, and rodent control are key post-disaster teaching points.
