NEET-PG 2022 - Community Medicine NEET-PG Practice Questions and MCQs
Question 1: Considering that dogs are the most common carriers of rabies and that the disease predominantly affects children in developing countries, what is the most effective and direct method to significantly reduce the incidence of rabies?
- A. Conduct rabies testing for all dogs
- B. Control the stray dog population and vaccinate all dogs (Correct Answer)
- C. Enhance laboratory testing capabilities
- D. Improve healthcare worker training for disease surveillance
Explanation: ***Control the stray dog population and vaccinate all dogs*** - As dogs are the primary reservoirs of rabies, controlling their population, coupled with widespread **dog vaccination**, is the most direct and effective strategy to break the transmission cycle to humans. - This approach tackles the root cause of the disease in areas where dog-mediated transmission is endemic, leading to a significant reduction in human rabies cases. *Conduct rabies testing for all dogs* - While testing identifies infected animals, it is **resource-intensive** and impractical for large dog populations, especially in low-resource settings, and does not prevent future infections. - This strategy is reactive rather than **proactive** in preventing the spread of rabies. *Enhance laboratory testing capabilities* - Improving laboratory testing capabilities is crucial for **surveillance** and accurate diagnosis but does not directly prevent rabies transmission at the source. - It's a supportive measure that helps monitor disease burden but isn't the most effective **primary intervention** for incidence reduction. *Improve healthcare worker training for disease surveillance* - Training healthcare workers enhances case detection and reporting, which is vital for **epidemiological monitoring** and timely post-exposure prophylaxis (PEP). - However, it does not address the fundamental issue of rabies transmission from dogs to humans and is not a direct prevention method for reducing disease incidence.
Question 2: Based on healthcare utility values and life expectancy, which of the following measures can be calculated? Consider a scenario where the average life expectancy for a woman in Japan is 87 years, and there is an increase in life expectancy due to healthcare advancements.
- A. HALE
- B. DALY
- C. DFLE
- D. QALY (Correct Answer)
Explanation: ***QALY*** - **Quality-Adjusted Life Years (QALYs)** combine the length of life with the **quality of life** lived, taking into account healthcare utility values (e.g., from 0 for dead to 1 for perfect health). - An increase in life expectancy due to healthcare advancements, coupled with assumed utility values, directly enables the calculation of QALYs gained or lost. *HALE* - **Health-Adjusted Life Expectancy (HALE)** is a measure of the average number of years that a person can expect to live in "**full health**" by adjusting for years lived in less than full health due to disease or injury. - While it incorporates health status, it specifically focuses on time lived in full health rather than the utility-weighted quality of life over the entire lifespan as QALYs do. *DALY* - **Disability-Adjusted Life Years (DALYs)** measure the total number of healthy years lost due to disease, disability, or premature death. - DALYs are a measure of disease burden, quantifying years lost, whereas QALYs are a measure of health gains or health states. *DFLE* - **Disability-Free Life Expectancy (DFLE)** measures the expected number of years an individual will live without disability. - While it considers the absence of disability, it does not incorporate the concept of "utility values" or varying degrees of health-related quality of life beyond a binary disabled/non-disabled state, as QALYs do.
Question 3: In triage, which category of patients is classified as green?
- A. Medium risk patients
- B. High-risk patients
- C. Dead patients
- D. Minor injury patients (Correct Answer)
Explanation: ***Minor injury patients*** - Patients classified as **green** in triage are those with **minor injuries** that are not immediately life-threatening. - They can often wait for treatment without significant risk of deterioration and may be able to **walk and self-care** to some extent. *Medium risk patients* - This category generally corresponds to **yellow** in triage, indicating patients with **significant injuries** who require care within a few hours. - While not immediately life-threatening, their condition could worsen if treatment is delayed. *High-risk patients* - This category typically corresponds to **red** in triage, signifying patients with **life-threatening injuries** or conditions. - These patients require immediate medical attention to survive. *Dead patients* - Patients who are deceased or have injuries incompatible with life are typically categorized as **black** in triage. - This classification indicates that no medical intervention can save them.
Question 4: Which of the following agencies is primarily responsible for supporting school feeding programs globally?
- A. WFP (Correct Answer)
- B. UNDP
- C. UNICEF
- D. WHO
Explanation: ***WFP (World Food Programme)*** - **WFP** is the **primary UN agency** responsible for supporting **school feeding programs globally**, operating in over 60 countries and providing meals to millions of schoolchildren. - WFP's school feeding programs are the world's largest safety net initiative, combining hunger relief with education support, and are a **flagship program** of the organization. - The agency focuses specifically on food assistance and hunger, making school feeding programs a core component of their mission to achieve Zero Hunger. *UNICEF* - **UNICEF** does support child nutrition and welfare programs, including some school-based nutrition initiatives, but it is **not the primary agency** for school feeding programs. - UNICEF's broader mandate focuses on child rights, health, education, and protection, with nutrition being one component rather than the specialized focus that WFP has on food assistance. - UNICEF often **collaborates with WFP** on school feeding initiatives rather than leading them independently. *UNDP* - The **UNDP** (United Nations Development Programme) focuses on sustainable development, poverty alleviation, and resilient societies. - While food security is part of development goals, UNDP does not directly implement or primarily fund school feeding programs compared to WFP. *WHO* - The **WHO** (World Health Organization) is the leading international authority on public health, focusing on disease prevention, health standards, and health policy. - While WHO provides guidance on nutritional standards and healthy diets for children, it does **not implement or fund school feeding programs** - this operational role belongs to WFP.
Question 5: You are working in a primary health center (PHC) situated in a high seismic zone. Which of the following actions should you take as part of preparedness for an emergency?
- A. Ensure all financial and other resources are available for disaster preparedness.
- B. Increase public awareness through campaigns and loudspeakers.
- C. Follow instructions given over the phone or radio by higher officials.
- D. Conduct a simulation for the disaster and assess the response. (Correct Answer)
Explanation: ***Conduct a simulation for the disaster and assess the response.*** - **Simulation exercises** are crucial for testing the effectiveness of a disaster preparedness plan and identifying weaknesses in the response system. - This allows for refinement of protocols, training of personnel, and ensuring that all team members understand their roles during an actual emergency. *Ensure all financial and other resources are available for disaster preparedness.* - While important for effective disaster management, simply "ensuring" resources are available is not an action of preparedness, but rather an **enabling condition**. - This statement focuses on the availability of resources rather than a proactive step to prepare the PHC for an emergency. *Increase public awareness through campaigns and loudspeakers.* - **Public awareness campaigns** are vital for community preparedness, but this action is primarily for the general population and not a specific preparedness action for the PHC itself in terms of its operational readiness. - While a PHC might be involved in public awareness, its core preparedness involves internal actions to ensure its functionality during a disaster. *Follow instructions given over the phone or radio by higher officials.* - This describes a reaction during or immediately before a disaster, rather than a proactive **preparedness measure**. - Relying solely on real-time instructions from higher officials during an emergency without prior planning can lead to delays and inefficiencies.
Question 6: Which statement best describes the criteria for starting an urban community health center?
- A. Caters to a population of 1-1.5 lakh (Correct Answer)
- B. Referral center for 2-3 primary health centers
- C. Should have a 100-bed facility in metro cities
- D. No sub-district and district hospitals present in the area
Explanation: ***Caters to a population of 1-1.5 lakh*** - An **urban community health center (UCHC)** is designed to provide comprehensive primary healthcare services to an urban population of **1 to 1.5 lakh**. - This population criterion ensures effective service delivery and proper resource allocation for a designated urban area. *Referral center for 2-3 primary health centers* - This description typically applies to a **sub-district hospital** or a higher-level facility, which serve as referral centers for multiple primary health centers. - A UCHC primarily focuses on direct provision of primary care, not usually acting as a referral hub for other primary care units. *Should have a 100-bed facility in metro cities* - A **100-bed facility** is characteristic of a larger hospital, such as a district hospital, not an urban community health center. - UCHCs typically have minimal or no inpatient beds, focusing on outpatient services and emergency care rather than extensive hospitalization. *No sub-district and district hospitals present in the area* - This statement is not a criteria for a UCHC; in fact, UCHCs often function within a healthcare system that includes larger hospitals for referral of complex cases. - The presence or absence of higher-level facilities does not define the necessity or establishment of a UCHC.
Question 7: STEPwise approach to surveillance for Non-Communicable diseases step 2 is
- A. Biochemical Measurement
- B. Behavioral measurement
- C. Physical measurement (Correct Answer)
- D. Emotional Assessment
Explanation: ***Physical measurement*** - The **STEPwise approach** to NCD surveillance involves three steps, with Step 2 specifically focusing on **physical measurements**. - This step includes measurements like **blood pressure**, BMI, weight, height, and waist circumference, which provide crucial data on NCD risk factors. *Biochemical Measurement* - This is typically **Step 3** in the WHO STEPwise approach, focusing on biological measurements from blood or urine samples. - Examples include **blood glucose**, cholesterol levels, and other biomarkers. *Behavioral measurement* - This corresponds to **Step 1** of the WHO STEPwise approach, which involves self-reported data on lifestyle factors. - It covers aspects like **diet**, physical activity, and tobacco/alcohol consumption. *Emotional Assessment* - While emotional and mental health are relevant to overall well-being, **emotional assessment** is not a standard, distinct step in the core WHO STEPwise approach for NCD surveillance. - The STEPs focus on behavioral, physical, and biochemical indicators of NCD risk.
Question 8: Contaminated tubing and catheters will be disposed in which bag according to biomedical waste management?
- A. Yellow
- B. Blue
- C. White
- D. Red (Correct Answer)
Explanation: ***Red Container*** - The **red bag** is designated for **contaminated recyclable waste** including tubing, catheters, intravenous sets, and soiled plastic items. - This waste is highly infectious and undergoes **autoclaving** or **microwaving** to disinfect it before recycling. *Yellow Container* - The **yellow bag** is used for **highly infectious waste** such as human anatomical waste, medical dressings, and microbiological waste. - This waste is typically **incinerated** or undergoes deep burial. *Blue Container* - The **blue/white puncture-proof container** is used for **sharp objects** like needles, syringes with fixed needles, and scalpel blades. - This waste is often **autoclaved** and then shredded or vitrified to prevent reuse and injury. *White Container* - In some biomedical waste management systems, a **white translucent container** is used for **glassware** that is contaminated with blood or body fluids, such as broken glass ampoules or vials. - The specific color codes can vary slightly between regions, but the red bag is consistently for contaminated plastic/tubing.
