Disaster Management Practice Questions

Q: What is triage for?

To classify the priority of treatment. ***To classify the priority of treatment*** - **Triage** is the process of sorting patients to determine the **priority** of their treatment based on the **severity** of their condition and the likelihood of recovery, especially when resources are limited. - This system ensures that those who need immediate care most urgently receive it first, maximizing the number of lives saved. *To rehabilitate following a disaster* - **Rehabilitation** focuses on restoring health and functional abilities after an injury or illness, which occurs **post-treatment**, not as the initial classification of need. - This phase of care happens *after* triage has been completed and immediate medical needs have been addressed. *To prepare for a disaster* - **Disaster preparedness** involves planning and training *before* a disaster strikes to mitigate its effects and ensure an effective response. - Triage is a **response mechanism** utilized *during* or *immediately after* a disaster, not a preparatory measure. *To assess the impact of a disaster* - **Impact assessment** involves evaluating the damage, casualties, and overall consequences of a disaster. - While disaster impact assessment helps guide overall response, triage is specifically about **individual patient assessment** and prioritization for medical care.

Q: Patients are categorized on the basis of chances of survival in Disaster management:

Triage. ***Triage*** - **Triage** is the process of sorting and prioritizing patients based on the severity of their injuries and their chances of survival, especially in mass casualty incidents or disasters. - This system ensures that limited resources are allocated to maximize the number of survivors and provide the most effective care. *Tagging* - **Tagging** refers to the physical labeling of patients after they have been triaged, using color-coded tags (e.g., red for immediate, yellow for delayed, green for minor, black for expectant). - It is a result of the triage process, not the process of categorization itself. *Mitigation* - **Mitigation** involves measures taken to reduce the impact of a disaster or emergency, such as constructing earthquake-resistant buildings or developing flood control systems. - It focuses on preventing or lessening the severity of a disaster before it occurs, rather than categorizing patients. *Surge capacity* - **Surge capacity** is the ability of a healthcare system to expand its services and resources in response to an unexpected influx of patients, such as during a pandemic or mass casualty event. - It refers to the operational capability of the system, not the method of patient categorization.

Q: Natural disasters are all except?

Accidental radioactive gas leak from factory. ***Accidental radioactive gas leak from factory*** - This is primarily an **industrial accident** or a **technological disaster**, not a natural disaster. - While it can cause widespread harm, its origin is **human-made**, not from natural earth processes. *Floods* - **Floods** are considered natural disasters as they are caused by natural phenomena like heavy rainfall, overflowing rivers, or storm surges. - They result in significant environmental and infrastructural damage. *Tornado* - **Tornadoes** are natural disasters characterized by rapidly rotating columns of air that form from thunderstorms. - They cause immense destruction through extreme winds and are entirely a weather phenomenon. *Lightning strike* - A **lightning strike** is a natural electrical discharge during a thunderstorm. - While a single strike can cause localized damage or injury, it is a component of a larger natural weather event (thunderstorm) and is considered a natural occurrence.

Q: During the post-disaster period, the most commonly reported disease is:

Gastroenteritis. ***Gastroenteritis*** - Disasters often lead to **disruption of water supply and sanitation systems**, increasing the risk of **contaminated food and water**. - This contamination directly contributes to the spread of **enteric pathogens**, resulting in a surge of gastroenteritis cases. *Acute respiratory infections* - While common in crowded conditions and displaced populations, acute respiratory infections are usually associated with **poor ventilation** and close contact, not primary water and sanitation breakdown. - They tend to increase due to **stress** and **overcrowding** in shelters, but typically after the immediate threat of waterborne diseases. *Tetanus* - Tetanus is associated with **puncture wounds** contaminated with *Clostridium tetani* spores from soil or feces. - While increased injuries might occur during a disaster, **widespread environmental contamination** leading to a high incidence of tetanus is less common than waterborne diseases. *Urinary tract infection* - Urinary tract infections are primarily caused by **bacterial ascension** into the bladder and are less directly linked to large-scale environmental changes post-disaster. - Their incidence may increase due to **poor hygiene** or lack of access to proper sanitation facilities but is not typically the most reported widespread disease.

Q: Black colour in triage is for -

Dead patients. ***Dead patients*** - In a mass casualty incident (MCI) triage system, the **black tag** is assigned to patients who are deceased or have injuries so severe that survival is unlikely, often without available resources. - These individuals are identified as beyond medical help in the immediate emergent phase, allowing resources to be focused on patients with a higher chance of survival. *Low priority patients* - **Green tag** is typically assigned to patients who have minor injuries and can wait for treatment; they are considered "walking wounded." - This color indicates that their condition is stable and does not require immediate intervention. *Ambulatory patients* - Ambulatory patients, often referred to as the **"walking wounded,"** are categorized with a **green tag** in mass casualty triage. - They are individuals who can move on their own and have minor injuries that do not pose an immediate threat to life or limb. *High priority patients* - **Red tag** is used for patients with critical, life-threatening injuries who require immediate intervention to survive, such as those with severe bleeding or airway compromise. - This color signifies the highest priority for medical treatment due to the severity of their condition.

Q: Targeted critical agents used in a bioterrorist event are except?

Coxiella burnetii. ***Coxiella burnetii*** - This is the **correct answer** as it is classified as a **Category B biological agent**, not a Category A critical agent. - While *C. burnetii* causes **Q fever** and has high infectivity with potential for widespread illness, it typically has **lower mortality rates** compared to Category A agents. - Category B agents are second-priority because they are moderately easy to disseminate but cause lower mortality than Category A agents. *Ricinus communis* - This refers to **ricin toxin** derived from castor beans, classified as a **Category B agent**. - However, ricin is considered more dangerous than Q fever due to its potent toxicity and lack of antidote. - Can cause severe multi-organ damage upon inhalation or ingestion, though less lethal than Category A agents. *Smallpox* - Caused by **variola virus**, classified as a **Category A critical agent**. - High infectivity, severe illness, high mortality rate, and lack of natural immunity in most populations. - Historical use as a bioweapon and potential for rapid global spread make it a top-tier threat. *Viral hemorrhagic fevers - Junin virus* - **Category A critical agent** due to high infectivity, severe disease presentation, and high mortality rates. - Includes agents like Ebola, Marburg, Lassa, and Junin viruses that cause severe multi-system disease. - Person-to-person transmission potential and lack of effective treatments make these priority threats.

Q: Which of the following is a Category A bioterrorism agent?

Anthrax. ***Anthrax*** - **Anthrax**, caused by *Bacillus anthracis*, is classified as a **Category A** bioterrorism agent due to its high mortality rate, ease of dissemination, and potential for major public health impact. - It can manifest as cutaneous, inhalational, gastrointestinal, or injectional forms, with **inhalational anthrax** being the most lethal. *Brucella* - **Brucella** species cause brucellosis, which is classified as a **Category B** bioterrorism agent. - While it can be debilitating, it generally has a lower mortality rate and less public health impact than Category A agents. *Q fever* - **Q fever**, caused by *Coxiella burnetii*, is another **Category B** bioterrorism agent. - It causes a flu-like illness and can have chronic complications but is not as severe or easily disseminated as Category A agents. *Typhus fever* - **Typhus fever**, caused by *Rickettsia prowazekii* (epidemic typhus) or *Rickettsia typhi* (murine typhus), is a **Category B** bioterrorism agent. - It can cause severe illness but is not among the highest-priority agents like anthrax, smallpox, or botulism.

Q: Which of the following is a Category C bioterrorism agent?

Nipah virus. ***Nipah virus*** - **Nipah virus** is classified as a **Category C bioterrorism agent** due to its potential for high mortality, emerging threat, and ease of genetic engineering. - These agents are emerging pathogens that could be engineered for **mass dissemination** in the future and require ongoing surveillance. *Botulism* - **Botulism**, caused by *Clostridium botulinum* toxin, is a **Category A bioterrorism agent** due to its high mortality and ease of dissemination. - Category A agents pose the greatest threat to public health and national security. *Clostridium Perfringens* - *Clostridium perfringens* is classified as a **Category B bioterrorism agent** because it can be used to contaminate food and water supplies. - Category B agents are moderately easy to disseminate and cause moderate morbidity but lower mortality than Category A agents. *Plague* - **Plague**, caused by *Yersinia pestis*, is a **Category A bioterrorism agent** because of its high mortality, potential for aerosol dissemination, and risk of causing public panic. - The CDC categorizes agents based on the risk they pose to national security.

Q: Which vaccine is recommended in disasters -

Cholera. ***Cholera*** - **Cholera** outbreaks are a significant risk in disaster settings due to contaminated water sources and inadequate sanitation. - The **oral Cholera vaccine** can be rapidly deployed to prevent large-scale epidemics in vulnerable populations following disasters. *Typhoid* - While **typhoid** can be a concern in disaster areas, it is generally considered a lower priority for mass vaccination compared to cholera. - Vaccination efforts for **typhoid** are often more targeted towards specific high-risk groups rather than widespread disaster response. *Diphtheria* - **Diphtheria** vaccination is part of routine childhood immunization programs and is not typically a primary vaccine for immediate disaster response. - The risk of a widespread **diphtheria** outbreak due to a disaster is generally lower than that of waterborne diseases. *BCG* - The **BCG vaccine** protects against **tuberculosis** and is administered as part of routine infant immunization programs. - It is not indicated for emergency mass vaccination during disaster situations as **tuberculosis** transmission is not acutely elevated in these contexts.
