Environmental Impact Assessment Indian Medical PG Practice Questions and MCQs
Question 1: Which of the following is NOT a core component of the WHO's global STI control strategy?
- A. Case management
- B. Universal mandatory screening (Correct Answer)
- C. Strategic information systems
- D. Prevention services
Explanation: ***Universal mandatory screening*** - While screening is part of STI control, **universal mandatory screening** for all STIs in the general population is not a core component of the WHO's strategy due to feasibility, cost, and ethical considerations. - The strategy emphasizes **targeted screening** for at-risk populations and opportunistic screening. *Case management* - **Case management**, including accurate diagnosis and effective treatment, is a critical component for managing current infections and preventing further transmission. - This involves syndromic or etiologic approaches to treatment and partner notification. *Strategic information systems* - **Strategic information systems** are essential for monitoring trends, evaluating interventions, and informing policy decisions related to STI control. - This includes surveillance data, program monitoring, and research. *Prevention services* - **Prevention services** are a cornerstone of the WHO's strategy, aiming to reduce the incidence of new infections. - These services encompass health education, condom promotion and distribution, vaccination, and pre-exposure prophylaxis (PrEP).
Question 2: Which of the following phases are directly involved in the recovery phase of the disaster cycle?
- A. Response and Rehabilitation
- B. Mitigation and Rehabilitation
- C. Response and Preparedness
- D. Rehabilitation and Reconstruction (Correct Answer)
Explanation: ***Rehabilitation and Reconstruction*** - **Rehabilitation** is the short-term recovery phase focusing on restoring essential services, providing temporary shelter, medical care, and supporting affected populations to resume normal activities. - **Reconstruction** is the long-term recovery phase involving rebuilding damaged infrastructure, permanent housing, economic restoration, and development improvements. - These two phases together constitute the **recovery phase** of the disaster cycle according to standard disaster management frameworks (WHO, NDMA). *Mitigation and Rehabilitation* - While **rehabilitation** is correctly part of recovery, **mitigation** is traditionally considered a separate continuous phase or part of preparedness, focused on reducing future disaster risks. - **Mitigation** measures are implemented throughout the disaster cycle, not specifically as a direct component of the recovery phase. *Response and Rehabilitation* - **Response** refers to immediate life-saving actions during and immediately after a disaster (search and rescue, emergency medical care, evacuation). - **Response** precedes the recovery phase and is distinct from it, though **rehabilitation** is indeed part of recovery. *Response and Preparedness* - **Preparedness** involves planning, training, and resource allocation before a disaster occurs. - **Response** is the immediate action during/after the disaster. - Neither constitutes the recovery phase, which follows after the immediate response is complete.
Question 3: In an accident case, after the arrival of medical team, all should be done in early management except;
- A. Glasgow coma scale
- B. Check BP (Correct Answer)
- C. Stabilization of cervical vertebrae
- D. Check Respiration
Explanation: ***Check BP*** - In the **immediate/early management** of trauma (primary survey), while circulation assessment is crucial, the **initial assessment of circulation** focuses on: - **Pulse rate and quality** (radial, carotid) - **Capillary refill time** - **Skin color and temperature** - **Active hemorrhage control** - **Formal blood pressure measurement** with a cuff, while important, is typically recorded during or after these rapid initial assessments, as it takes more time to obtain an accurate reading. - In the context of this question, among the four options listed, BP measurement is relatively less immediate compared to the other life-saving priorities (airway protection, breathing assessment, C-spine stabilization, and GCS). - **Note:** This is a nuanced distinction - BP is assessed during primary survey, but the other three options have more immediate life-threatening implications if not addressed. *Glasgow coma scale* - **GCS assessment** is part of the **"D" (Disability)** step in the ATLS primary survey. - It is performed early to assess neurological status and level of consciousness. - GCS <8 indicates need for **definitive airway protection** (intubation). - This is a critical early assessment that guides immediate management decisions. *Stabilization of cervical vertebrae* - **C-spine immobilization** is part of the **"A" (Airway)** step - "Airway with cervical spine protection." - It is performed **simultaneously** with airway assessment using a **rigid cervical collar**. - This is the **first priority** in trauma management to prevent secondary spinal cord injury. - All trauma patients should be assumed to have C-spine injury until proven otherwise. *Check Respiration* - **Respiratory assessment** is part of the **"B" (Breathing)** step in the ATLS primary survey. - This involves checking: - **Respiratory rate and pattern** - **Chest wall movement** - **Air entry bilaterally** - **Signs of tension pneumothorax or flail chest** - This is an immediate life-saving priority and must be assessed early.
Question 4: Not under millennium development goals?
- A. Eradication of extreme poverty
- B. Global partnership for development
- C. Reduction of cardiovascular health hazards (Correct Answer)
- D. Sustainability of the environment
Explanation: ***Reduction of cardiovascular health hazards*** - The **Millennium Development Goals (MDGs)** focused on broader health issues like poverty, hunger, maternal and child health, and infectious diseases, rather than specific non-communicable diseases. - While improving health was a core tenet, specific targets for reducing **cardiovascular disease** burdens were not explicitly listed as one of the eight MDGs. *Eradication of extreme poverty* - This was the **first and overarching goal** of the MDGs, aiming to halve the proportion of people living on less than $1.25 a day by 2015. - It included targets related to **employment** and **hunger reduction**. *Global partnership for development* - This was the **eighth and final goal** of the MDGs, emphasizing international cooperation to achieve the other goals. - It focused on issues such as **aid, debt relief**, and **access to technology**. *Sustainability of the environment* - This was one of the **seven major MDGs (Goal 7)**, aiming to integrate principles of sustainable development into country policies and programs. - It included targets related to **reducing biodiversity loss** and increasing access to safe drinking water.
Question 5: ESI Act does not cover which of the following:
- A. Hotel employee
- B. Transporters
- C. Railway employees (Correct Answer)
- D. Factory employees
Explanation: ***Railway employees*** - The **Employees' State Insurance (ESI) Act** does not cover railway employees, as they typically fall under their own separate welfare schemes and medical facilities provided by the **Indian Railways**. - Railway employees have specific service conditions and benefits, including comprehensive medical care that operates **independently of ESI**. *Hotel employee* - Employees in hotels are generally covered by the **ESI Act** if the establishment meets the eligibility criteria regarding the number of employees. - The ESI scheme provides social security benefits, including **medical care and financial assistance**, to eligible hotel workers. *Transporters* - Workers employed in transport undertakings are usually covered under the **ESI Act**, especially if the establishment employs the requisite number of persons. - This coverage ensures their access to **medical services and other ESI benefits**. *Factory employees* - Factory employees are a primary group intended to be covered by the **ESI Act**, provided the factory meets the minimum employee threshold. - The Act's main aim was to provide **social security and health benefits** to industrial and factory workers.
Question 6: In the primary survey, which of the following is not included?
- A. ABC
- B. CECT to look for bleeding (Correct Answer)
- C. Exposure of the whole body
- D. Recording BP
Explanation: ***CECT to look for bleeding*** - A **CECT scan** is a detailed imaging study that is performed during the **secondary survey**, not during the primary survey. - The primary survey focuses on the immediate **ABCDE assessment** (Airway, Breathing, Circulation, Disability, Exposure) to identify and treat immediately life-threatening conditions. - While identifying bleeding is critical, detailed imaging like CECT is done only after initial stabilization is achieved in the primary survey. *ABC* - **Airway, Breathing, and Circulation (ABC)** are the fundamental first three components of the primary survey. - These represent the immediate priorities for life support in trauma management according to ATLS guidelines. - Ensuring a patent airway, adequate breathing, and circulatory stability are critical first steps. *Exposure of the whole body* - **Exposure** (the "E" in ABCDE) is an essential part of the primary survey. - Complete exposure allows full assessment for injuries and prevents missing critical external wounds. - This step also involves maintaining **thermoregulation** to prevent hypothermia. *Recording BP* - **Recording blood pressure** is a crucial part of assessing circulation (the "C") during the primary survey. - It helps quickly evaluate hemodynamic status and identify potential signs of shock or internal bleeding. - Vital signs monitoring is integral to the initial trauma assessment.
Question 7: Solid waste contaminated with blood and body fluids is classified under which category according to Bio-Medical Waste Management Rules?
- A. 6 (Correct Answer)
- B. 9
- C. 5
- D. 3
Explanation: ***Correct: Category 6*** - According to the **Bio-Medical Waste Management Rules, 2016**, solid waste contaminated with blood and body fluids is categorized under **Category 6**. - This includes items like **dressings, plaster casts, cotton swabs, and bags containing residual or discarded blood and blood components**. - These items require specific handling and disposal methods as they pose infection risk due to visible soiling or soaking with blood and bodily fluids. *Incorrect: Category 9* - Category 9 refers to **discarded linen, mattresses, and beddings contaminated with blood or body fluids**. - While also dealing with blood-contaminated materials, this category is specifically for textile/fabric items, not general solid waste like dressings and swabs. *Incorrect: Category 5* - Category 5 covers **discarded medicines and cytotoxic drugs**, including expired, discarded, or contaminated pharmaceutical products. - This category deals with pharmaceutical waste, not materials contaminated with blood and body fluids. *Incorrect: Category 3* - Category 3 is designated for **microbiology, biotechnology, and other clinical laboratory waste**, including laboratory cultures, stocks or specimens of microorganisms, live or attenuated vaccines, and human and animal cell cultures. - This category focuses on infectious biological agents and laboratory waste, not general solid waste contaminated with blood and body fluids.
Question 8: GATHER Approach is useful for
- A. Counselling (Correct Answer)
- B. Chlorination of water
- C. Data analysis
- D. Refuse disposal
Explanation: ***Counselling*** - The **GATHER approach** is a widely recognized framework specifically designed to provide **structured and effective counseling** in reproductive health and family planning. - Each letter in GATHER stands for a step in the counseling process: **G**reet, **A**sk, **T**ell, **H**elp, **E**xplain, and **R**eturn, ensuring comprehensive client interaction. *Chlorination of water* - **Chlorination** is a method used for **water purification** and disinfection to kill pathogens, not for counseling. - It involves adding chlorine or chlorine-releasing compounds to water. *Data analysis* - **Data analysis** refers to the process of inspecting, cleansing, transforming, and modeling data to discover useful information and support decision-making. - It uses various statistical and computational techniques. *Refuse disposal* - **Refuse disposal** refers to the methods used to manage and get rid of waste materials, such as landfilling, incineration, or recycling. - It is an environmental sanitation practice.
Question 9: Which of the following is not a source of environmental radiation?
- A. Uranium
- B. Radon
- C. CO (Correct Answer)
- D. Radium
Explanation: ***CO*** - **Carbon monoxide (CO)** is a toxic gas produced by incomplete combustion, but it is **not radioactive** and thus not a source of environmental radiation. - Its danger comes from its ability to bind to **hemoglobin**, preventing oxygen transport, not from emitting radiation. *Radium* - **Radium** is a highly **radioactive element** found naturally in the environment as a decay product of uranium and thorium. - It emits **alpha and gamma radiation**, contributing significantly to natural background radiation. *Uranium* - **Uranium** is a naturally occurring **radioactive element** found in rocks, soil, and water. - It decays through a series of steps, emitting **alpha, beta, and gamma radiation**, and is a primary source of environmental background radiation. *Radon* - **Radon** is a **radioactive gas** that is formed from the decay of uranium in soil and rocks. - It is a significant source of **indoor environmental radiation exposure** and a known cause of lung cancer.
Question 10: Soil may act as a reservoir for all EXCEPT-
- A. Tetanus
- B. Anthrax
- C. Brucellosis (Correct Answer)
- D. Coccidioidomycosis
Explanation: **Explanation:** The core concept here is distinguishing between **soil-borne pathogens** (geophilic organisms) and **zoonotic pathogens** that require a living animal host for survival and transmission. **Why Brucellosis is the Correct Answer:** Brucellosis is a classic zoonotic disease caused by *Brucella* species. Its primary reservoir is **infected animals** (cattle, goats, sheep, and pigs). Humans are infected through direct contact with animal secretions, consumption of unpasteurized dairy, or inhalation of aerosols in slaughterhouses. While the bacteria can survive briefly in the environment, soil is **not** a natural reservoir or a significant source of infection for Brucellosis. **Analysis of Incorrect Options:** * **Tetanus (*Clostridium tetani*):** The soil is the primary reservoir. The organism exists as highly resistant spores that can survive in soil and manure for years. * **Anthrax (*Bacillus anthracis*):** Known as a "soil-borne" infection. Spores can remain viable in soil for decades, especially in "anthrax districts" with specific alkaline and calcium-rich soil conditions. * **Coccidioidomycosis:** This is a fungal infection caused by *Coccidioides immitis*. The fungus grows as a mold in the **soil** of arid regions (e.g., Southwestern US). **NEET-PG High-Yield Pearls:** * **Soil-transmitted Helminths (STH):** Remember the "ASH" mnemonic—*Ascaris*, *Strongyloides*, and Hookworm (*Ancylostoma*). * **Bacterial Soil Reservoirs:** *Clostridium tetani*, *Clostridium botulinum*, and *Bacillus anthracis*. * **Fungal Soil Reservoirs:** *Histoplasma capsulatum*, *Cryptococcus neoformans*, and *Coccidioides*. * **Brucellosis Key Fact:** It is often called "Undulant Fever" or "Malta Fever." The most common route of transmission in India is the consumption of raw milk.
