Disaster Management Practice Questions

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: Red Cross Society was founded by

Henry Dunant. ***Henry Dunant*** - **Henry Dunant** was a Swiss businessman and humanitarian who witnessed the aftermath of the **Battle of Solferino** in 1859. - His efforts led to the establishment of the **International Committee of the Red Cross (ICRC)** in 1863 and the first **Geneva Convention** in 1864. - He was awarded the first **Nobel Peace Prize** in 1901 for his humanitarian work. *Florence Nightingale* - **Florence Nightingale** was a pioneering British nurse and social reformer, known as the founder of **modern nursing**. - She gained prominence during the **Crimean War** (1853-1856) for improving sanitary conditions in military hospitals. - While a contemporary of Dunant and a humanitarian, she did not found the Red Cross Society. *Rockefeller* - The **Rockefeller family** is a prominent American industrial, political, and banking family known for extensive philanthropy. - The **Rockefeller Foundation** (established 1913) has supported public health and medical research globally. - However, they were not involved in the founding of the Red Cross. *Clara Barton* - **Clara Barton** was an American nurse and humanitarian who founded the **American Red Cross** in 1881. - She was inspired by the **International Red Cross** and brought the movement to the United States. - However, she did not found the original **International Committee of the Red Cross** - that was Henry Dunant.

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 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.

Q: Black color code is used in four color code systems of triage management in disaster for:

Dead or moribund patients. ***Dead or moribund patients*** - The **black color code** in triage signifies patients who are either deceased or have injuries so severe that survival is unlikely, even with immediate intervention. - These patients are typically assigned **comfort care** as resources are prioritized for those with a higher chance of survival. *High priority patients* - **High priority patients**, who require immediate medical attention to survive, are typically designated with a **red color code**. - These individuals have life-threatening injuries but still have a good prognosis if treated promptly. *Ambulatory patients* - **Ambulatory patients** who have minor injuries and can walk are usually assigned a **green color code**. - They are considered "walking wounded" and can often wait for treatment until more critical patients are stabilized. *Low priority patients* - **Low priority patients** or those with significant injuries but whose conditions are stable and not immediately life-threatening are typically designated with a **yellow color code**. - They require medical attention but can safely wait for a few hours without significant risk of deterioration.

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

Bacillus anthracis. ***Bacillus anthracis*** - **Anthrax**, caused by *Bacillus anthracis*, is a prime example of a Category A bioterrorism agent due to its high mortality, ease of dissemination, and potential for major public health impact. - 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**. - While it causes **gas gangrene** and food poisoning with moderate severity, it lacks the **high transmissibility** and widespread impact characteristic of Category A agents. *NIPAH virus* - **Nipah virus** is classified as a Category C priority pathogen. - It has the potential for high morbidity and mortality, but its **epidemiological characteristics** (e.g., lower transmissibility than Category A agents) preclude its inclusion in Category A. *Coxiella burnetii* - *Coxiella burnetii*, the causative agent of **Q fever**, is classified as a Category B bioterrorism agent. - Category B agents are moderately easy to disseminate and can cause **moderate morbidity** and low mortality, which is less severe than Category A agents.
