Disaster Management — MCQs

Q: Which of the following is not a fundamental aspect of disaster management?

Disaster awakening. ### Explanation The fundamental framework of disaster management is structured around the **Disaster Management Cycle**, which consists of specific phases designed to reduce the impact of a catastrophe. **Why "Disaster Awakening" is the correct answer:** There is no recognized phase or term called "Disaster Awakening" in standard public health or WHO disaster management protocols. While public awareness is a component of preparedness, "awakening" is not a formal technical pillar of the cycle. **Analysis of Incorrect Options (The True Phases):** * **Disaster Preparedness:** These are measures taken before a disaster to ensure an effective response (e.g., stockpiling medicines, training personnel, and creating evacuation plans). * **Disaster Response:** This occurs immediately after the event strikes. It focuses on life-saving activities such as Triage, search and rescue, and providing emergency medical aid. * **Disaster Mitigation:** These are long-term measures taken to minimize the risk and impact of a disaster before it occurs (e.g., building earthquake-resistant hospitals or improving drainage to prevent floods). **High-Yield Clinical Pearls for NEET-PG:** * **The Disaster Cycle:** Divided into **Pre-disaster phase** (Mitigation, Preparedness), **Impact phase** (Response), and **Post-disaster phase** (Recovery, Rehabilitation, Reconstruction). * **Triage:** The most critical medical component of the Response phase. Remember the color coding: **Red** (Immediate/High Priority), **Yellow** (Urgent/Stable), **Green** (Ambulatory/Minor), and **Black** (Dead/Moribund). * **Tagging:** In a disaster, the **Triage Tag** is usually tied to the victim's left wrist. * **Epidemiology:** The most common post-disaster communicable diseases are usually water-borne (e.g., Cholera, Leptospirosis) or related to overcrowding (e.g., Measles).

Q: What is the most common epidemic after a disaster?

Gastroenteritis. **Explanation:** The most common epidemic following a disaster is **Gastroenteritis** (Option A). This is primarily due to the immediate and widespread disruption of basic sanitary infrastructure. Disasters—especially floods and earthquakes—lead to the contamination of drinking water sources with sewage and the breakdown of food hygiene. Overcrowding in temporary shelters further facilitates the fecal-oral transmission of pathogens like *Vibrio cholerae*, *Salmonella*, and *Norovirus*. **Analysis of Options:** * **Respiratory Infections (Option B):** While common in overcrowded relief camps (e.g., Acute Respiratory Infections), they typically rank second to water-borne diseases in the immediate post-disaster phase. * **Wound Infections (Option C):** These are common individual complications following trauma (e.g., crush injuries in earthquakes), but they do not typically manifest as "epidemics" involving the general population. * **Leptospirosis (Option D):** This is a specific risk following floods (zoonotic transmission via rodent urine), but its incidence is much lower compared to the universal occurrence of diarrheal diseases. **High-Yield NEET-PG Pearls:** * **First Priority in Disaster:** Search, rescue, and first aid. * **Most common cause of post-disaster death:** Diarrheal diseases (Gastroenteritis). * **Triage:** The process of rapidly classifying victims to maximize survivors. * **Tag Colors:** Red (High priority/Immediate), Yellow (Medium priority/Delayed), Green (Ambulatory/Minor), Black (Dead/Moribund). * **Chlorination:** The most important single measure to prevent post-disaster epidemics is ensuring a safe water supply (target residual chlorine: 0.5 mg/L).

Q: During disaster management, which condition is classified under the international code green signal?

Ambulatory patient. ### Explanation In disaster management, **Triage** is the process of rapidly categorizing victims based on the severity of their injuries and the likelihood of survival with treatment. This ensures the most efficient use of limited resources. The international color-coding system is the gold standard for this classification. **Correct Answer: C. Ambulatory patient** The **Green Code** is assigned to "walking wounded" or ambulatory patients. These individuals have minor injuries (e.g., simple lacerations, minor sprains) that do not require immediate systemic stabilization. They can wait for treatment or even assist in their own care, making them the lowest priority for evacuation. **Analysis of Incorrect Options:** * **A. High priority treatment (Red):** This represents the "Immediate" category. These patients have life-threatening injuries (e.g., tension pneumothorax, major hemorrhage) but have a high chance of survival if treated immediately. * **B. Medium priority treatment (Yellow):** This represents the "Delayed" category. These patients have serious but non-life-threatening injuries (e.g., stable fractures, large wounds without shock) and can wait 1–6 hours for definitive care. * **D. Dead patients (Black):** This represents the "Expectant" category. These are victims who are either already dead or have injuries so catastrophic (e.g., exposed brain matter, cardiac arrest) that survival is unlikely even with care. **High-Yield Clinical Pearls for NEET-PG:** * **Mnemonic (M.A.S.S.):** Move, Assess, Sort, Send. * **Triage Tagging:** Always tagged on the wrist or ankle, never on clothing. * **The "Golden Hour":** The first 60 minutes after trauma where prompt medical intervention has the highest impact on survival. * **Inverted Triage:** In military settings or specific tactical situations, those with minor injuries (Green) may be treated first to return them to the front lines quickly.

Q: Epidemics after a disaster are caused by all of the following except:

Leishmaniasis. ### Explanation The occurrence of epidemics following a disaster is primarily driven by changes in population density (overcrowding), displacement, disruption of water and sanitation systems, and collapse of public health infrastructure. **Why Leishmaniasis is the Correct Answer:** Leishmaniasis is a **chronic protozoal disease** with a long incubation period (weeks to months). It is transmitted by the sandfly, which requires specific stable environmental conditions to breed. Disasters typically disrupt the ecological niche of sandflies or cause immediate acute health crises. Because of its slow progression and specific vector requirements, Leishmaniasis does not manifest as a sudden "epidemic" in the immediate post-disaster phase (the first 4–8 weeks). **Analysis of Incorrect Options:** * **Leptospirosis:** Common after floods. Contaminated water (containing rodent urine) comes into contact with skin/mucosa, leading to rapid outbreaks. * **Rickettsiosis:** Overcrowding in refugee camps and poor hygiene lead to infestations of lice or mites, which are vectors for epidemic typhus (Rickettsia prowazekii). * **Acute Respiratory Infections (ARI):** These are the **most common cause of morbidity and mortality** in disaster-affected populations due to overcrowding, poor ventilation in shelters, and exposure to elements. **NEET-PG High-Yield Pearls:** 1. **Most common post-disaster epidemic:** Diarrheal diseases (Cholera, Dysentery). 2. **Most common cause of death:** Acute Respiratory Infections (ARI). 3. **Phase of Epidemics:** Epidemics usually do not occur in the "Immediate Phase" (0–2 days) but emerge during the "Post-impact Phase" (weeks to months). 4. **Vector-borne risks:** Malaria and Dengue are high-risk if the disaster creates stagnant water (floods) or if the population is displaced to endemic areas.

Q: Which of the following is not a fundamental aspect of disaster management?

Disaster propagation. **Explanation:** The core objective of Disaster Management is to reduce the impact of a catastrophe through a systematic cycle of actions. **Disaster Propagation** is the correct answer because it refers to the spreading or worsening of a disaster's effects, which is the exact opposite of the goals of public health intervention. **Understanding the Disaster Management Cycle:** The fundamental aspects are categorized into Pre-disaster, During-disaster, and Post-disaster phases: * **Disaster Mitigation (Option A):** These are measures taken to reduce the risk and damage before a disaster occurs (e.g., building earthquake-resistant structures or planting mangroves to prevent flooding). * **Disaster Preparedness (Option B):** This involves planning, organizing, and training personnel to respond effectively (e.g., stockpiling medicines, conducting mock drills, and establishing early warning systems). * **Disaster Response (Option C):** This is the immediate assistance provided during or immediately after the event to save lives and meet basic needs (e.g., Triage, Search and Rescue, and First Aid). **High-Yield Clinical Pearls for NEET-PG:** * **Triage:** The most critical component of Disaster Response. In a mass casualty incident, the **Red Tag** (Highest Priority) indicates immediate life-threatening conditions. * **The Disaster Cycle:** Mitigation $\rightarrow$ Preparedness $\rightarrow$ Response $\rightarrow$ Recovery. * **Epidemiology of Disasters:** The most common cause of death in the post-impact phase is usually related to communicable diseases due to overcrowding and poor sanitation (e.g., Cholera, Leptospirosis). * **Golden Hour:** The first hour after the disaster where prompt medical intervention has the highest impact on reducing mortality.

Q: In triage color coding, what does yellow signify?

Delayed treatment.. In Disaster Management, **Triage** is the process of prioritizing patients based on the severity of their condition and the urgency of treatment required to maximize the number of survivors. ### **Explanation of the Correct Answer** **Option B (Delayed treatment)** is correct. The **Yellow** tag is assigned to "Urgent" cases. These patients have serious injuries (e.g., stable fractures, large wounds without profuse bleeding) that require medical attention but are not immediately life-threatening. They can safely wait for **1–6 hours** while more critical patients are stabilized. ### **Analysis of Incorrect Options** * **Option A & C (Immediate/Emergency treatment):** These correspond to the **Red** tag. These patients have life-threatening injuries (e.g., tension pneumothorax, airway obstruction, severe hemorrhage) but have a high chance of survival if treated immediately (within the "Golden Hour"). * **Option D (Least chance of survival):** This corresponds to the **Black** tag. These patients are either dead or "moribund" (injuries so severe that survival is unlikely even with care, such as 90% burns or open brain injuries). In a mass casualty incident, resources are diverted away from them to save those with better prognoses. ### **High-Yield NEET-PG Clinical Pearls** * **Color Coding Mnemonic (RYGB):** 1. **Red:** Immediate (Life-threatening) 2. **Yellow:** Delayed (Serious but stable) 3. **Green:** Minor (Ambulatory/"Walking wounded") 4. **Black:** Dead/Moribund * **Blue Tag:** Sometimes used in specific protocols for patients requiring intensive care but with a poor prognosis (intermediate between Red and Black). * **Triage Tagging:** Usually tied to the left wrist or ankle. * **START Protocol:** Simple Triage and Rapid Treatment is the most common algorithm used, focusing on **RPM** (Respiration, Perfusion, and Mental Status).

Disaster Management Indian Medical PG Practice Questions and MCQs

Question 1: In a triage system for disaster management, what does the Red color code indicate?

A. Patients with minor injuries
B. Uninjured patients
C. Patients with critical injuries requiring immediate attention (Correct Answer)
D. Patients with fatal injuries or those unlikely to survive

Explanation: **Explanation:** In disaster management, **Triage** is the process of prioritizing patients based on the severity of their condition to maximize the number of survivors. The color-coding system is a standardized tool used to categorize victims during mass casualty incidents (MCI). **1. Why Option C is Correct:** The **Red Tag (Immediate)** indicates patients with life-threatening injuries who have a high probability of survival if medical intervention is provided immediately (within the "Golden Hour"). These patients typically have airway obstructions, tension pneumothorax, or severe external hemorrhage. **2. Analysis of Incorrect Options:** * **Option A (Minor injuries):** These are **Green Tag (Minor/Walking Wounded)** patients. They have stable vitals and can wait several hours for treatment. * **Option B (Uninjured):** These individuals do not require medical triage tags; they are usually directed to a safe zone or observation area. * **Option D (Fatal/Unlikely to survive):** These are **Black Tag (Dead/Moribund)** patients. In a resource-constrained disaster setting, those with catastrophic injuries (e.g., exposed brain matter, cardiac arrest) are deprioritized to save those with a better prognosis. **3. High-Yield Clinical Pearls for NEET-PG:** * **Yellow Tag (Delayed):** Indicates "Urgent" cases (e.g., stable fractures, large wounds without hemorrhage) that require care but are not immediately life-threatening. * **START Protocol:** The most common triage algorithm is **Simple Triage and Rapid Treatment**. It focuses on three parameters: **Respirations, Perfusion, and Mental Status (RPM).** * **Red Tag Criteria (RPM):** Respiratory rate >30/min, absent radial pulse (or capillary refill >2 seconds), or inability to follow simple commands. * **Triage Sieve:** The initial primary triage performed at the site of the disaster.

Question 2: Which of the following is not a fundamental aspect of disaster management?

A. Disaster response
B. Disaster mitigation
C. Disaster awakening (Correct Answer)
D. Disaster preparedness

Explanation: ### Explanation The fundamental framework of disaster management is structured around the **Disaster Management Cycle**, which consists of specific phases designed to reduce the impact of a catastrophe. **Why "Disaster Awakening" is the correct answer:** There is no recognized phase or term called "Disaster Awakening" in standard public health or WHO disaster management protocols. While public awareness is a component of preparedness, "awakening" is not a formal technical pillar of the cycle. **Analysis of Incorrect Options (The True Phases):** * **Disaster Preparedness:** These are measures taken before a disaster to ensure an effective response (e.g., stockpiling medicines, training personnel, and creating evacuation plans). * **Disaster Response:** This occurs immediately after the event strikes. It focuses on life-saving activities such as Triage, search and rescue, and providing emergency medical aid. * **Disaster Mitigation:** These are long-term measures taken to minimize the risk and impact of a disaster before it occurs (e.g., building earthquake-resistant hospitals or improving drainage to prevent floods). **High-Yield Clinical Pearls for NEET-PG:** * **The Disaster Cycle:** Divided into **Pre-disaster phase** (Mitigation, Preparedness), **Impact phase** (Response), and **Post-disaster phase** (Recovery, Rehabilitation, Reconstruction). * **Triage:** The most critical medical component of the Response phase. Remember the color coding: **Red** (Immediate/High Priority), **Yellow** (Urgent/Stable), **Green** (Ambulatory/Minor), and **Black** (Dead/Moribund). * **Tagging:** In a disaster, the **Triage Tag** is usually tied to the victim's left wrist. * **Epidemiology:** The most common post-disaster communicable diseases are usually water-borne (e.g., Cholera, Leptospirosis) or related to overcrowding (e.g., Measles).

Question 3: Triage refers to?

A. Availability of a level of medical care
B. Categorization of patients according to the level of severity (Correct Answer)
C. Medical personnel skill level
D. None of the above

Explanation: ### Explanation **Triage** is derived from the French word *trier*, meaning "to sort." In disaster management, it refers to the process of rapidly screening and categorizing patients based on the **severity of their injuries** and their **prognosis for survival** with immediate medical intervention. The primary goal of triage is to "do the greatest good for the greatest number" when resources are limited. #### Why Option B is Correct: Triage is fundamentally a system of prioritization. Patients are sorted into color-coded categories to ensure that those with life-threatening but treatable conditions receive care first, while those with minor injuries or those who are beyond help are deferred. #### Why Other Options are Incorrect: * **Option A:** The availability of medical care refers to "Resource Allocation" or "Medical Surge Capacity," not the sorting of patients. * **Option C:** Medical personnel skill level refers to "Competency" or "Staffing Tiers." While triage requires skilled personnel (usually the most experienced physician/nurse), the term itself does not define the skill level. #### High-Yield Clinical Pearls for NEET-PG: * **Color Coding System:** * **Red (Immediate):** High priority; life-threatening injuries but treatable (e.g., tension pneumothorax, airway obstruction). * **Yellow (Delayed):** Stable for the moment but requires observation (e.g., compound fractures). * **Green (Minor):** "Walking wounded"; can wait or assist others. * **Black (Dead/Moribund):** Deceased or injuries so severe that survival is unlikely even with care. * **Tagging:** In a disaster, the triage tag is usually tied to the **left wrist** or an uninjured limb. * **Re-triage:** Triage is a dynamic process; a patient’s status can change, requiring constant reassessment.

Question 4: What is the most common epidemic after a disaster?

A. Gastroenteritis (Correct Answer)
B. Respiratory infection
C. Wound infection
D. Leptospirosis

Explanation: **Explanation:** The most common epidemic following a disaster is **Gastroenteritis** (Option A). This is primarily due to the immediate and widespread disruption of basic sanitary infrastructure. Disasters—especially floods and earthquakes—lead to the contamination of drinking water sources with sewage and the breakdown of food hygiene. Overcrowding in temporary shelters further facilitates the fecal-oral transmission of pathogens like *Vibrio cholerae*, *Salmonella*, and *Norovirus*. **Analysis of Options:** * **Respiratory Infections (Option B):** While common in overcrowded relief camps (e.g., Acute Respiratory Infections), they typically rank second to water-borne diseases in the immediate post-disaster phase. * **Wound Infections (Option C):** These are common individual complications following trauma (e.g., crush injuries in earthquakes), but they do not typically manifest as "epidemics" involving the general population. * **Leptospirosis (Option D):** This is a specific risk following floods (zoonotic transmission via rodent urine), but its incidence is much lower compared to the universal occurrence of diarrheal diseases. **High-Yield NEET-PG Pearls:** * **First Priority in Disaster:** Search, rescue, and first aid. * **Most common cause of post-disaster death:** Diarrheal diseases (Gastroenteritis). * **Triage:** The process of rapidly classifying victims to maximize survivors. * **Tag Colors:** Red (High priority/Immediate), Yellow (Medium priority/Delayed), Green (Ambulatory/Minor), Black (Dead/Moribund). * **Chlorination:** The most important single measure to prevent post-disaster epidemics is ensuring a safe water supply (target residual chlorine: 0.5 mg/L).

Question 5: Which of the following statements about triage is FALSE?

A. Red tag indicates first priority.
B. Black tag indicates last priority.
C. Yellow tag indicates a patient who will survive if treatment is given immediately. (Correct Answer)
D. Green tag indicates a patient who will survive even if treatment is given after hours.

Explanation: ### Explanation **1. Why Option C is the correct (False) statement:** In disaster management, the **Yellow Tag** (Medium Priority) is for patients who are stable but require observation and medical care. They are "delayed" cases who can wait for a short period (usually 1–6 hours) without immediate threat to life. The description in Option C—"survive if treatment is given **immediately**"—actually defines the **Red Tag** (High Priority). Red tag patients have life-threatening injuries (e.g., airway obstruction, tension pneumothorax) that require intervention within the "Golden Hour." **2. Analysis of Incorrect Options:** * **Option A (Red Tag):** True. Red indicates the highest priority (Emergent). These patients are treated and transported first. * **Option B (Black Tag):** True. Black indicates the dead or "moribund" (those with injuries incompatible with life, such as massive brain matter evisceration). In a resource-limited disaster setting, they are given the lowest priority to save those with better prognoses. * **Option D (Green Tag):** True. Green indicates the "walking wounded." These patients have minor injuries (e.g., simple fractures, abrasions) and can wait for several hours or even days. **3. High-Yield Clinical Pearls for NEET-PG:** * **Triage Color Coding:** * **Red:** Immediate (Priority I) * **Yellow:** Delayed (Priority II) * **Green:** Minor/Walking Wounded (Priority III) * **Black:** Dead/Moribund (Priority 0) * **Mnemonic:** Remember **R-Y-G-B** (Red, Yellow, Green, Black) in descending order of urgency. * **Triage Tagging:** The tag is usually tied to the left wrist or ankle. * **Re-triage:** Triage is a continuous process; a patient's status can change from Yellow to Red if they deteriorate. * **START Protocol:** Simple Triage and Rapid Treatment is the most common algorithm used, focusing on **RPM** (Respiration, Perfusion, and Mental Status).

Question 6: During disaster management, which condition is classified under the international code green signal?

A. High priority treatment
B. Medium priority treatment
C. Ambulatory patient (Correct Answer)
D. Dead patients

Explanation: ### Explanation In disaster management, **Triage** is the process of rapidly categorizing victims based on the severity of their injuries and the likelihood of survival with treatment. This ensures the most efficient use of limited resources. The international color-coding system is the gold standard for this classification. **Correct Answer: C. Ambulatory patient** The **Green Code** is assigned to "walking wounded" or ambulatory patients. These individuals have minor injuries (e.g., simple lacerations, minor sprains) that do not require immediate systemic stabilization. They can wait for treatment or even assist in their own care, making them the lowest priority for evacuation. **Analysis of Incorrect Options:** * **A.

These are victims who are either already dead or have injuries so catastrophic (e.g., exposed brain matter, cardiac arrest) that survival is unlikely even with care. **High-Yield Clinical Pearls for NEET-PG:** * **Mnemonic (M.A.S.S.):** Move, Assess, Sort, Send. * **Triage Tagging:** Always tagged on the wrist or ankle, never on clothing. * **The "Golden Hour":** The first 60 minutes after trauma where prompt medical intervention has the highest impact on survival. * **Inverted Triage:** In military settings or specific tactical situations, those with minor injuries (Green) may be treated first to return them to the front lines quickly.

Question 7: Epidemics after a disaster are caused by all of the following except:

A. Leptospirosis
B. Rickettsiosis
C. Leishmaniasis (Correct Answer)
D. Acute respiratory infection

Explanation: ### Explanation The occurrence of epidemics following a disaster is primarily driven by changes in population density (overcrowding), displacement, disruption of water and sanitation systems, and collapse of public health infrastructure. **Why Leishmaniasis is the Correct Answer:** Leishmaniasis is a **chronic protozoal disease** with a long incubation period (weeks to months).

Question 8: Which of the following is not a fundamental aspect of disaster management?

A. Disaster mitigation
B. Disaster preparedness
C. Disaster response
D. Disaster propagation (Correct Answer)

Explanation: **Explanation:** The core objective of Disaster Management is to reduce the impact of a catastrophe through a systematic cycle of actions. **Disaster Propagation** is the correct answer because it refers to the spreading or worsening of a disaster's effects, which is the exact opposite of the goals of public health intervention. **Understanding the Disaster Management Cycle:** The fundamental aspects are categorized into Pre-disaster, During-disaster, and Post-disaster phases: * **Disaster Mitigation (Option A):** These are measures taken to reduce the risk and damage before a disaster occurs (e.g., building earthquake-resistant structures or planting mangroves to prevent flooding). * **Disaster Preparedness (Option B):** This involves planning, organizing, and training personnel to respond effectively (e.g., stockpiling medicines, conducting mock drills, and establishing early warning systems). * **Disaster Response (Option C):** This is the immediate assistance provided during or immediately after the event to save lives and meet basic needs (e.g., Triage, Search and Rescue, and First Aid). **High-Yield Clinical Pearls for NEET-PG:** * **Triage:** The most critical component of Disaster Response.

Question 9: In triage color coding, what does yellow signify?

A. Immediate treatment is required.
B. Delayed treatment. (Correct Answer)
C. Emergency treatment.
D. Least chance of survival.

Explanation: In Disaster Management, **Triage** is the process of prioritizing patients based on the severity of their condition and the urgency of treatment required to maximize the number of survivors. ### **Explanation of the Correct Answer** **Option B (Delayed treatment)** is correct. The **Yellow** tag is assigned to "Urgent" cases. These patients have serious injuries (e.g., stable fractures, large wounds without profuse bleeding) that require medical attention but are not immediately life-threatening. They can safely wait for **1–6 hours** while more critical patients are stabilized. ### **Analysis of Incorrect Options** * **Option A & C (Immediate/Emergency treatment):** These correspond to the **Red** tag. These patients have life-threatening injuries (e.g., tension pneumothorax, airway obstruction, severe hemorrhage) but have a high chance of survival if treated immediately (within the "Golden Hour"). * **Option D (Least chance of survival):** This corresponds to the **Black** tag. These patients are either dead or "moribund" (injuries so severe that survival is unlikely even with care, such as 90% burns or open brain injuries). In a mass casualty incident, resources are diverted away from them to save those with better prognoses. ### **High-Yield NEET-PG Clinical Pearls** * **Color Coding Mnemonic (RYGB):** 1. **Red:** Immediate (Life-threatening) 2. **Yellow:** Delayed (Serious but stable) 3. **Green:** Minor (Ambulatory/"Walking wounded") 4. **Black:** Dead/Moribund * **Blue Tag:** Sometimes used in specific protocols for patients requiring intensive care but with a poor prognosis (intermediate between Red and Black). * **Triage Tagging:** Usually tied to the left wrist or ankle. * **START Protocol:** Simple Triage and Rapid Treatment is the most common algorithm used, focusing on **RPM** (Respiration, Perfusion, and Mental Status).

Question 10: What is the meaning of triage?

A. Sorting of patients based on the availability of medical resources and the severity of their condition. (Correct Answer)
B. Patients are divided into three groups.
C. Severely injured patients are taken first.
D. Used in military hospitals.

Explanation: **Explanation:** **Triage** is derived from the French word *'trier'*, meaning "to sort." In disaster management, it is the process of rapidly evaluating and categorizing patients to determine the priority of treatment and transport. **Why Option A is correct:** The fundamental goal of triage is to provide the **"greatest good for the largest number of people"** when medical resources are overwhelmed. It is not based solely on the severity of the injury, but on the patient's prognosis and the resources available to save them. This ensures that care is prioritized for those who are most likely to survive with immediate intervention. **Why other options are incorrect:** * **Option B:** While the word root implies "three," modern triage systems (like the Color Coding system) typically use **four** categories (Red, Yellow, Green, Black). * **Option C:** In a disaster, the "severely injured" might include those who are "expectant" (unsalvageable). These patients are actually given the lowest priority (Black tag) to save resources for those with a better chance of survival. * **Option D:** While triage originated in military medicine (Napoleonic Wars), it is now a standard protocol in all civilian emergency departments and disaster sites. **High-Yield NEET-PG Clinical Pearls:** * **Color Coding System:** 1. **Red (Immediate):** High priority; life-threatening but treatable (e.g., tension pneumothorax, airway obstruction). 2. **Yellow (Delayed):** Serious but not immediately life-threatening (e.g., stable fractures). 3. **Green (Minor):** "Walking wounded." 4. **Black (Dead/Expectant):** Deceased or injuries so severe they cannot survive given current resources. * **Tagging:** Triage tags should be tied to the **wrist or ankle**, never to clothing. * **Re-triage:** Triage is a continuous process; a patient's status can change from Yellow to Red rapidly.
