2. The primary parameter that distinguishes a Yellow tag from a Red tag in START is a normal RPM (Respirations <30, Perfusion <2 sec, Mental Status intact) but inability to walk.
3. The only time CPR is initiated during mass casualty triage is the 5 rescue breaths in pediatric JumpSTART.
4. Disaster Management Act in India was enacted in December 2005.
5. The Prime Minister is the Chairman of NDMA.
6. The Mitigation phase involves actions preventing disasters (e.g., building codes).
7. The Preparedness phase includes mock drills, training, and emergency kits.
8. The Recovery phase focuses on long-term rehabilitation and rebuilding.
9. Cholera and Leptospirosis are the most common epidemics following floods.
10. Crush syndrome causes acute kidney injury due to myoglobinuria and life-threatening hyperkalemia.
11. Methyl Isocyanate (MIC) was the gas responsible for the 1984 Bhopal Gas Tragedy.
12. Anthrax post-exposure prophylaxis is Ciprofloxacin or Doxycycline.
13. Primary blast injuries affect hollow organs (Blast lung, ruptured eardrums).
14. Time, Distance, and Shielding are the golden rules of radiation protection.
15. Atropine and Pralidoxime (2-PAM) are the specific antidotes for Nerve Gas (Sarin) exposure.
16. The jaw-thrust maneuver is the only safe method to open an airway in suspected spinal trauma.
17. A flail chest is recognized by paradoxical chest movement.
18. For dry chemical burns, always brush the powder off before irrigating with water.
19. A tourniquet is the first-line intervention for life-threatening arterial extremity bleeding.
20. In Reverse Triage (lightning strikes), the dead/apneic are treated FIRST.
2. 10 High-Yield Points for AIIMS NORCET
1. Rule of Nines Precision: Be exact on calculations. Remember the anterior trunk is 18%, posterior trunk is 18%, each full leg is 18%, each full arm is 9%, head is 9%, perineum is 1%.
2. Reverse Triage is a favorite NORCET trap: Usually, we leave the apneic (Black tag) behind. But in lightning strikes, respiratory arrest is often temporary, and early CPR saves lives. Treat the pulseless first!
3. Triage Officer Limitations: A triage officer never provides definitive care (like splinting or IV fluids). Their only clinical interventions are opening the airway and controlling massive hemorrhage.
4. JumpSTART cutoff: JumpSTART is specifically for children < 8 years old or weighing < 100 lbs. If they look like a teenager, use adult START.
5. Nerve Agent Mnemonics: DUMBELS (Diarrhea, Urination, Miosis, Bradycardia, Emesis, Lacrimation, Salivation) points directly to organophosphates or nerve gases. Give Atropine fast.

6. MCI Definition: It is not about the number of victims; it is about resources being outmatched by the needs.
7. Hospital Evacuation Priority: In a fire (RACE), evacuate ambulatory patients first, then wheelchair-bound, then bedridden. In disaster decanting (discharging to free beds), send home the most stable, elective procedure patients.
8. Snake Bite Absolute No-No’s: Never incise, never suck the venom, never apply a tight tourniquet. Immobilize at or below heart level.
9. Earthquake Crush Syndrome: The immediate killer is Hyperkalemia (leads to cardiac arrhythmias); the delayed killer is Acute Renal Failure. Flood them with Normal Saline immediately.
10. Fire Extinguisher Protocol (PASS): Pull the pin, Aim at the base of the fire, Squeeze the handle, Sweep from side to side.
3. Important Disaster Management Colour Codes and Their Significance
Red (Immediate): Life-threatening injury requiring immediate intervention. Patient can survive with immediate medical care. (e.g., tension pneumothorax, massive arterial bleeding, RR >30).
Yellow (Delayed): Serious but not immediately life-threatening injury. Care can be delayed for a short time (usually up to 1-2 hours) without loss of life. (e.g., stable abdominal trauma, large bone fractures).
Green (Minor/Minimal): “Walking wounded.” Minor injuries requiring localized care. Patients are ambulatory and stable. (e.g., minor lacerations, sprains).
Advertisements
Black (Expectant/Deceased): Injuries are incompatible with life, or the patient is already deceased/apneic despite airway repositioning. No CPR provided (except pediatric rescue breaths).

Q1: In a mass casualty incident, the START triage system assesses which three primary parameters to categorize patients?
Correct Option: B
Rationale: The START (Simple Triage and Rapid Treatment) method relies on the RPM acronym: Respiration (breathing rate), Perfusion (capillary refill or radial pulse), and Mental Status (ability to follow simple commands) to rapidly classify victims in under 60 seconds.
Q2: You are the triage nurse at a disaster site. You assess a victim who is breathing at a rate of 34 breaths per minute. According to the START triage algorithm, which color tag should be applied?
Correct Option: A
Rationale: In the START algorithm, if the respiratory rate is greater than 30 breaths per minute, the patient is immediately tagged as Red (Immediate). No further assessment of perfusion or mental status is required for this categorization.
Q3: A victim of a building collapse is apneic. The nurse opens the airway, but the victim still does not breathe. What is the appropriate triage tag?
Correct Option: D
Rationale: If a victim is not breathing, the rescuer attempts to open the airway. If spontaneous breathing does not resume after basic airway maneuvers, the patient is tagged Black (Deceased/Expectant) to conserve resources for salvageable victims.
Q4: How does the JumpSTART triage system for pediatric patients differ from the adult START system when assessing an apneic child with a palpable pulse?
Correct Option: B
Rationale: Children are more likely to experience primary respiratory arrest than cardiac arrest. Therefore, if a child is apneic but has a palpable pulse, the rescuer gives 5 rescue breaths. If breathing resumes, they are tagged Red; if not, they are tagged Black.
Q5: During a mass casualty incident, a patient is unable to walk. Their respiratory rate is 24 breaths/min, capillary refill is less than 2 seconds, and they can appropriately squeeze your hand upon command. What is the correct triage category?
Correct Option: B
Rationale: The patient passes all RPM parameters (Respirations < 30, Perfusion < 2 seconds, Mental status intact), but cannot walk (which excludes them from Green). Therefore, they are categorized as Yellow (Delayed).
Q6: What is the very first action a triage officer should take when arriving at a mass casualty scene using the START method?
Correct Option: B
Rationale: The first step in START is to clear the “walking wounded.” By directing those who can walk to a specific area, the triage officer instantly categorizes them as Green (Minor), allowing responders to focus on non-ambulatory, critically injured victims.
Q7: In the context of disaster management, what does “Reverse Triage” mean, and in which specific scenario is it utilized?
Correct Option: C
Rationale: In a lightning strike incident, standard triage rules are inverted (“Reverse Triage”). Victims struck by lightning who are apneic/pulseless often have a reversible respiratory/cardiac arrest and need immediate CPR, whereas those who are breathing will likely recover on their own.
Q8: A victim has a respiratory rate of 20, but the capillary refill time is 4 seconds. The triage nurse should:
Correct Option: B
Rationale: A capillary refill of more than 2 seconds indicates inadequate perfusion. According to START, the nurse should quickly attempt to control severe bleeding (if visible) and tag the patient as Red (Immediate).
Q9: What is the primary role of the triage nurse at the disaster scene?
Correct Option: B
Rationale: The absolute priority of the triage nurse is to sort (triage) patients rapidly and allocate the appropriate color tag. They must resist the urge to provide comprehensive care on the spot, as this delays the assessment of other victims.
Q10: At which age or weight is the pediatric JumpSTART triage system generally applied instead of the adult START system?
Correct Option: B
Rationale: JumpSTART is scientifically designed for children who appear to be under 8 years old or weigh less than 100 lbs (45 kg). For those who appear older or heavier, the adult START triage algorithm is used.
Q11: A victim’s respiratory rate is 22/min, radial pulse is present, but the victim is confused and unable to follow simple commands. What is the appropriate triage category?
Correct Option: A
Rationale: Even though respirations and perfusion are within acceptable limits, the patient fails the “Mental Status” parameter (cannot follow simple commands), indicating potential severe traumatic brain injury or hypoxia. They must be tagged Red.
Q12: What distinguishes a Mass Casualty Incident (MCI) from a Multiple Casualty Incident?
Correct Option: B
Rationale: The defining characteristic of a Mass Casualty Incident (MCI) is not a specific number of victims, but the fact that the healthcare system’s resources (personnel, equipment, facilities) are overwhelmed by the demand.
Q13: When performing primary triage, a victim is found with severe evisceration of the bowels. They are unresponsive, apneic, and have no pulse. The appropriate action is:
Correct Option: C
Rationale: In an MCI, resources are scarce. A pulseless, apneic patient requires CPR, which is resource-intensive and not performed during disaster primary triage (except the rescue breaths in pediatric JumpSTART). The patient is tagged Black.
Q14: The term “Expectant” in disaster triage corresponds to which color tag?
Correct Option: D
Rationale: “Expectant” refers to victims whose injuries are so severe that they are expected to die given the current limitations of resources, or they are already deceased. They are assigned a Black tag.
Q15: During secondary triage at the casualty clearing station, a patient previously tagged Yellow develops severe respiratory distress and a dropping oxygen saturation. The nurse should:
Correct Option: B
Rationale: Triage is a dynamic, continuous process. Patients must be continually reassessed (secondary triage). If a patient’s condition deteriorates, their triage category must be upgraded (from Yellow to Red) to reflect their new immediate need for care.
Q16: Which phase of the disaster management cycle involves activities such as developing emergency operation plans, conducting mock drills, and stocking emergency kits?
Correct Option: B
Rationale: The preparedness phase involves taking actions prior to an emergency to facilitate a safe and effective response. This includes planning, training, conducting mock drills, and stockpiling supplies.
Q17: The construction of earthquake-resistant buildings and strict enforcement of zoning laws are examples of which disaster management phase?
Correct Option: A
Rationale: Mitigation refers to long-term measures taken to prevent hazards from developing into disasters altogether, or to reduce the effects of disasters. Structural interventions like earthquake-resistant engineering are classic mitigation strategies.
Q18: Who serves as the ex-officio Chairperson of the National Disaster Management Authority (NDMA) in India?
Correct Option: C
Rationale: Under the Disaster Management Act, 2005, the National Disaster Management Authority (NDMA) is the apex body for disaster management in India, headed by the Prime Minister.
Q19: The Disaster Management Act in India, which laid the foundation for institutions like NDMA and NDRF, was enacted in which year?
Correct Option: B
Rationale: The Disaster Management Act was enacted by the Government of India on December 26, 2005, primarily as a legislative response to the devastating 2004 Indian Ocean Tsunami.
Q20: What is the primary focus of the Recovery phase in the disaster management cycle?
Correct Option: C
Rationale: The recovery phase begins after the immediate threat to life has passed. It focuses on returning the affected community to normal or better conditions through rebuilding, psychological support, and economic rehabilitation.
Q21: When conducting a vulnerability assessment of a community, a Community Health Nurse is engaging in which aspect of disaster management?
Correct Option: B
Rationale: Vulnerability assessments identify populations at high risk (e.g., elderly, disabled) and are a crucial part of the preparedness phase, allowing nurses to tailor emergency plans before a disaster strikes.
Q22: The Incident Command System (ICS) is a standardized management tool for meeting the demands of emergency situations. Which of the following is a core principle of ICS?
Correct Option: B
Rationale: ICS is based on a rigid, clear chain of command, unified command structure, and a manageable span of control (usually one supervisor to 3-7 subordinates) to eliminate confusion during chaotic emergency responses.
Q23: In disaster planning, what is the recommended minimum duration for which a personal emergency kit (“Go Bag”) should contain food, water, and supplies?
Correct Option: B
Rationale: Emergency management agencies (like FEMA and NDMA) universally recommend that households prepare a 72-hour (3-day) emergency kit, as it may take up to three days for emergency responders to reach affected areas and restore basic services.
Q24: During an earthquake, the safest immediate action to take if you are indoors is:
Correct Option: C
Rationale: “Drop, Cover, and Hold on” is the evidence-based recommendation. Running outside during shaking causes most injuries due to falling debris, glass, and structural collapse. Doorways are no longer considered the safest place.
Q25: Which psychological reaction is most commonly observed in survivors immediately following a catastrophic disaster (the “Impact Phase”)?
Correct Option: C
Rationale: During the immediate impact phase, survivors typically exhibit a state of shock, numbness, panic, or confusion. The “Honeymoon phase” (community bonding) and “Disillusionment phase” (anger/blame) occur later in the timeline. PTSD is a long-term diagnosis.
Q26: Which of the following waterborne diseases is highly likely to cause an epidemic following severe flooding in a densely populated region?
Correct Option: B
Rationale: Leptospirosis is a bacterial infection transmitted through water contaminated with animal urine (often rodents). Flooding greatly increases human exposure to this contaminated water, leading to significant outbreaks.
Q27: A victim rescued after being trapped under building rubble for 12 hours is diagnosed with Crush Syndrome. The nurse should prioritize monitoring for which life-threatening electrolyte imbalance?
Correct Option: B
Rationale: Crush syndrome involves massive skeletal muscle destruction (rhabdomyolysis). The damaged muscle cells release large amounts of intracellular potassium into the bloodstream, leading to life-threatening hyperkalemia and potential cardiac arrest.
Q28: What is the most critical nursing intervention to prevent acute renal failure in a patient presenting with rhabdomyolysis post-earthquake?
Correct Option: C
Rationale: Aggressive IV hydration is critical to maintain urine output, flush myoglobin (the muscle protein causing kidney damage) out of the renal tubules, and prevent acute kidney injury.
Q29: A tsunami warning has been issued for a coastal community. The primary characteristic of a tsunami wave approaching the shore is:
Correct Option: A
Rationale: A sudden withdrawal (receding) of ocean water (drawback) is often the first visual warning sign that a massive tsunami wave is approaching. It indicates that the trough of the wave has reached the shore before the crest.
Q30: During a severe heatwave, a patient presents to the emergency department unconscious, with hot, dry skin and a core body temperature of 105°F (40.5°C). The nurse recognizes these as classic signs of:
Correct Option: C
Rationale: Heat stroke is a medical emergency characterized by a core temperature >104°F (40°C), central nervous system dysfunction (unconsciousness, confusion), and classically, anhidrosis (hot, dry skin), though sweating can sometimes persist.
Q31: Differentiating between Epidemic, Endemic, and Pandemic is crucial in disaster management. An outbreak of a disease that spreads across multiple continents and affects a large number of people is termed a(n):
Correct Option: B
Rationale: A pandemic is an epidemic that has spread over multiple countries or continents, usually affecting a massive number of people (e.g., COVID-19). Endemic refers to the constant presence of a disease in a specific geography.
Q32: In the event of a cyclone (hurricane), what is the safest area within a structural building to take shelter if evacuation is not possible?
Correct Option: C
Rationale: To minimize injury from flying debris and shattered glass, individuals should shelter in a windowless, interior room (like a closet or bathroom) on the lowest level of a sturdy structure.
Q33: Landslides frequently occur after heavy rainfall or earthquakes. What is the immediate priority for a community health nurse when a landslide risk is identified?
Correct Option: C
Rationale: The immediate priority before or during a landslide risk is life preservation through rapid evacuation from the path of the landslide to safe zones.
Q34: The infamous 1984 Bhopal Gas Tragedy in India, one of the world’s worst industrial disasters, was caused by the leakage of which highly toxic chemical?
Correct Option: B
Rationale: The Bhopal disaster was caused by the accidental release of around 40 tons of highly toxic Methyl Isocyanate (MIC) gas from the Union Carbide India Limited pesticide plant.
Q35: A biological attack utilizing Anthrax has occurred. What is the drug of choice for post-exposure prophylaxis in adults?
Correct Option: B
Rationale: Cutaneous, gastrointestinal, and inhalation anthrax (Bacillus anthracis) are bacterial infections. The CDC recommends Ciprofloxacin or Doxycycline as the primary antibiotics for post-exposure prophylaxis and treatment.
Q36: During a radiological/nuclear disaster, which principle dictates the fundamental approach to minimizing radiation exposure to healthcare workers?
Correct Option: A
Rationale: The core principles of radiation protection are reducing the Time of exposure, maximizing the Distance from the radiation source, and using appropriate Shielding (like lead aprons or concrete).
Q37: Following a terrorist bomb blast in a confined space, a victim presents with hemoptysis, dyspnea, and hypoxia, but has no visible external chest trauma. The nurse suspects which blast injury?
Correct Option: A
Rationale: Primary blast injuries are caused directly by the blast overpressure wave, which severely damages air-filled hollow organs like the lungs (causing pulmonary barotrauma/blast lung), eardrums, and gastrointestinal tract without outward signs of trauma.
Q38: A patient is exposed to a nerve agent (such as Sarin gas) and presents with pinpoint pupils, excessive salivation, vomiting, and muscle twitching. What is the definitive antidote the nurse should prepare?
Correct Option: C
Rationale: Nerve agents are potent acetylcholinesterase inhibitors leading to a cholinergic crisis (SLUDGE/DUMBELS symptoms). Atropine blocks the muscarinic receptors, and Pralidoxime reactivates the inhibited enzyme.
Q39: In the event of a fire inside the hospital ward, the nurse should follow the RACE protocol. What does the “C” in RACE stand for?
Correct Option: B
Rationale: The RACE protocol stands for Rescue (patients in immediate danger), Alarm (pull the fire alarm), Confine (close doors and windows to prevent spread), and Extinguish/Evacuate.
Q40: An internal mass casualty incident requires freeing up hospital beds rapidly. Which patient is the most appropriate for the nurse to recommend for early discharge or transfer?
Correct Option: C
Rationale: During disaster decanting, patients who are stable, do not require continuous life-saving interventions, IV medications, or acute monitoring are prioritized for discharge to clear beds for incoming trauma victims.
Q41: You are applying first aid to a victim of a building collapse with bright red, spurting blood from their thigh. Direct pressure fails to stop the bleeding. What is the next priority action?
Correct Option: B
Rationale: Current trauma guidelines (e.g., STOP THE BLEED) mandate that if direct pressure is ineffective for massive, life-threatening extremity arterial bleeding, a tourniquet should be applied immediately proximal to the bleeding site.
Q42: A patient with severe hypovolemic shock following a trauma should be placed in which optimal position by the emergency response nurse?
Correct Option: C
Rationale: Elevating the legs (while keeping the head and trunk flat) promotes venous return from the lower extremities to the vital organs, improving cardiac output and cerebral perfusion in hypovolemic shock.
Q43: Using the Rule of Nines, calculate the total body surface area (TBSA) burned for an adult patient who suffered superficial partial-thickness burns to the entire right arm, the entire anterior chest and abdomen, and the entire right leg.
Correct Option: B
Rationale: Entire right arm = 9%. Entire anterior trunk (chest & abdomen) = 18%. Entire right leg = 18%. Total = 9 + 18 + 18 = 45%.
Q44: What is the absolute contraindication during the first-aid management of a patient bitten by a venomous snake in a rural disaster setting?
Correct Option: C
Rationale: Incision and suction are contraindicated as they cause severe tissue damage, do not effectively remove venom, and increase the risk of massive infection. Current first aid focuses on immobilization and rapid transport.
Q45: A rescuer locates a victim with a suspected cervical spine injury following an earthquake. How should the airway be opened to check for breathing?
Correct Option: B
Rationale: The jaw-thrust maneuver is the safest way to open the airway in a patient with a suspected spinal injury because it minimizes movement of the cervical spine, preventing potential spinal cord transection.
Q46: The first aid for severe frostbite on a victim’s fingers during a cold wave disaster involves:
Correct Option: B
Rationale: Frostbite is treated by rapid, controlled rewarming in warm water. Rubbing the tissues causes severe mechanical damage to the frozen cells. Dry heat (fire) can cause burns due to lack of sensation.
Q47: A victim has suffered a traumatic amputation of their index finger. How should the nurse appropriately handle the amputated part for transport?
Correct Option: D
Rationale: The amputated part must be kept cool but should never be placed directly on ice or directly in water (which causes tissue damage/maceration). Wrapping in slightly moist gauze, sealing in a watertight bag, and putting the bag on ice/water slurry is standard.
Q48: A patient is brought to the triage area post-industrial explosion with paradoxical chest wall movement (one side of the chest moves inward during inspiration). This is a hallmark sign of:
Correct Option: C
Rationale: Flail chest occurs when multiple contiguous ribs are fractured in two or more places, creating a “free-floating” segment of the rib cage. This segment moves paradoxically (inward on inspiration, outward on expiration) due to intrathoracic pressure changes.
Q49: When managing a dry chemical powder burn on a victim’s skin, the immediate first step is to:
Correct Option: B
Rationale: Dry chemicals must be brushed off first. If water is applied directly to certain dry chemicals (like dry lime), it reacts rapidly, generating massive amounts of heat and causing severe thermal burns on top of the chemical injury. Once brushed off, then flush with water.
Q50: During CPR in an adult victim in a disaster setting, the recommended compression-to-ventilation ratio for a single rescuer is:
Correct Option: B
Rationale: According to AHA guidelines, the universal compression-to-ventilation ratio for adult CPR (for both single and two rescuers) is 30 chest compressions followed by 2 rescue breaths, at a rate of 100-120 compressions per minute.
