NEET-PG 2015 - Community Medicine Practice Questions

Q: Which of the following is NOT a duty of an ASHA worker?

Administering zero dose of DPT and OPV. ***Correct: Administering zero dose of DPT and OPV*** - **ASHA workers do NOT administer vaccines** - this is strictly beyond their scope of practice - According to **NRHM guidelines**, ASHAs are **facilitators and mobilizers** for immunization, not vaccine administrators - Only **ANMs and trained health workers** are authorized to administer vaccines including DPT and OPV - ASHAs role is to **identify beneficiaries, create awareness, and escort mothers/children to immunization centers** - Vaccine administration requires technical training and cold chain management that ASHAs are not equipped for *Incorrect: Assessing the success of national programs under ANM* - While this is also not a primary ASHA duty, the question asks for what is NOT a duty - Program assessment is done at district/state levels through monitoring and evaluation teams - However, between administering vaccines (strictly prohibited) vs program assessment (not their role but may provide data), vaccine administration is more clearly NOT their duty *Incorrect: Primary screening for prevalence of non-communicable diseases* - This **IS a duty** of ASHA workers under **NPCDCS** (National Programme for Prevention and Control of Cancer, Diabetes, CVD and Stroke) - ASHAs conduct basic screening for hypertension, diabetes, and common cancers using simple tools - They refer suspected cases to appropriate health facilities for confirmation and management *Incorrect: All of the options* - This is incorrect because primary NCD screening IS part of ASHA duties, and administering vaccines is the most clearly defined non-duty among the options

Q: Protein quality assessment is best done by?

NPU. ***NPU*** - **Net Protein Utilization (NPU)** is considered the best method for assessing protein quality because it measures the percentage of ingested protein that is actually retained and utilized by the body. - It accounts for both the **digestibility** of the protein and the **biological value** of the absorbed amino acids, providing a comprehensive assessment. *Biological value* - **Biological Value (BV)** measures the proportion of absorbed protein from food that becomes incorporated into proteins in the organism's body. - While important, BV does not account for the **digestibility** of the protein, meaning some protein may not be absorbed even if its amino acid profile is excellent. *Digestibility coefficient* - The **digestibility coefficient** measures the proportion of food protein that is absorbed from the gastrointestinal tract. - It only reflects the extent of **absorption** and does not provide information about how efficiently the absorbed amino acids are utilized once inside the body for protein synthesis. *Amino acid score* - The **amino acid score** compares the amino acid profile of a test protein with the amino acid requirements of humans. - This score identifies the **limiting amino acid** but does not factor in the protein's digestibility or how effectively the absorbed amino acids are used by the body.

Q: In the context of malaria control, when is regular insecticidal spray recommended based on the Annual Parasite Index (API)?

> 2. ***> 2*** - Regular insecticidal spray, particularly **Indoor Residual Spraying (IRS)**, is a key malaria control measure recommended when the **Annual Parasite Index (API) is greater than 2**. - An API greater than 2 indicates **high endemicity** with a significant burden of malaria transmission in the community, necessitating aggressive vector control strategies. - According to **NVBDCP (National Vector Borne Disease Control Programme) guidelines**, API > 2 defines high-risk areas where routine IRS is implemented as a core intervention. *> 1* - An API between 1-2 represents **moderate endemicity**, where the focus is primarily on **active case detection, prompt treatment, and targeted interventions** rather than universal spraying. - While vector control remains important, routine widespread IRS is not the standard recommendation at this threshold. *< 2* - An API of less than 2 (which includes both moderate and low endemic areas) does not routinely warrant universal insecticidal spraying programs. - In areas with API < 2, **case management, surveillance, and selective vector control** are prioritized over widespread IRS campaigns. *< 1* - An API of less than 1 indicates **low endemicity**, where malaria transmission is minimal and sporadic. - In such areas, **surveillance, prompt case detection and treatment, and targeted interventions** are the mainstay, with IRS reserved only for focal outbreaks or high-risk pockets.

Q: Pneumonic plague is spread by:

Droplet infection. ***Correct: Droplet infection*** - Pneumonic plague is a severe form of plague that affects the **lungs** and is transmitted through **respiratory droplets** expelled by an infected person or animal during coughing or sneezing. - This direct person-to-person transmission distinguishes it from other forms of plague. - It is the **only form of plague** that can spread directly from human to human without an animal or flea vector. *Incorrect: Bite of infected flea* - This is the primary mode of transmission for **bubonic plague**, where the bacterium *Yersinia pestis* is transmitted from rodents to humans via infected fleas. - While bubonic plague can progress to pneumonic plague, the initial transmission route for the pneumonic form itself is not flea bites. *Incorrect: Direct contact with infected tissue* - Direct contact with infected tissues or fluids can lead to **septicemic plague** or sometimes bubonic plague, especially in cases where there is a break in the skin. - This is not the typical or primary route for the spread of pneumonic plague, which is respiratory. *Incorrect: Ingestion of contaminated food* - Ingestion of contaminated food or water is a route for various **gastrointestinal infections** and diseases like salmonella or cholera. - It is not a known or common method for the transmission of any form of plague, including pneumonic plague.

Q: What is the nutritional contribution of the Mid-Day Meal Scheme in terms of pulses?

Provides 30 gm of pulses per day. ***Provides 30 gm of pulses per day*** - The Mid-Day Meal Scheme specifies the provision of **30 grams of pulses** daily for **upper primary classes (VI-VIII)**, and 20 grams for primary classes (I-V), contributing to protein intake. - This quantity ensures a consistent supply of **plant-based protein** as part of a balanced diet for schoolchildren. - The question refers to the commonly cited **30g standard for upper primary**, which is the most frequently referenced figure in examinations. *Provides 30% of daily protein needs* - While pulses contribute to protein intake, specifying a fixed **30% of daily protein needs** is not a direct nutritional guideline of the scheme for pulses alone. - The scheme focuses on providing a certain **quantity of pulses in grams**, from which the protein contribution is derived. *Provides 50% of daily energy needs* - The Mid-Day Meal Scheme aims to provide **300 kcal for primary** and **700 kcal for upper primary classes**, but this is derived from the entire meal composition (cereals, pulses, vegetables), not just pulses. - The scheme's **energy contribution** is holistic and represents approximately 33% of daily energy requirements, not 50%. *None of the options* - One of the provided options accurately reflects a specific guideline of the Mid-Day Meal Scheme regarding pulses. - The scheme has clear stipulations for the **quantity of pulses in grams** to be served.

Q: In immediate disaster response management (first 24-48 hours), which of the following is not typically practiced?

Mass vaccination. ***Mass vaccination*** - **Mass vaccination** is typically a strategy for **preparedness/prevention phase** or **post-disaster disease prevention**, not an immediate disaster response activity. - Immediate disaster response focuses on **saving lives, providing emergency medical care, establishing shelter, and restoring critical infrastructure**, rather than large-scale preventative health campaigns. - Mass vaccination requires **planning, logistics, cold chain management**, which are incompatible with chaotic immediate response scenarios. *Triage* - **Triage** is a **critical and immediate** component of disaster response, involving the **prioritization of injured patients** for treatment based on severity and survival likelihood. - It ensures limited resources are allocated effectively to **maximize lives saved** during the acute phase. - Typically uses **color-coded tags** (red-immediate, yellow-delayed, green-minor, black-deceased). *Rehabilitation* - While **rehabilitation** is part of the **recovery phase** (weeks to months post-disaster), **early rehabilitation activities** may begin during the immediate response period. - Basic rehabilitation services like **mobility aids, psychological first aid**, can be initiated alongside acute care. - This makes it partially practiced even in immediate response, unlike mass vaccination which is never immediate. *Search and rescue* - **Search and rescue** is the **primary immediate response activity**, focusing on locating and extracting survivors from disaster-affected areas. - Time-critical operation following the **"golden period"** principle where survival rates decrease rapidly after 72 hours. - Involves specialized teams with equipment for **debris removal, victim location, and emergency extraction**.

Q: Which of the following is the MOST important vital statistic in a population?

Mortality rate. ***Mortality rate*** - The **mortality rate** directly reflects the health status and overall well-being of a population by indicating the number of deaths per unit population. - A high mortality rate signals underlying public health issues, inadequate healthcare, or poor living conditions, making it the **most critical vital statistic** for assessing population health and guiding interventions. - It serves as a **key indicator** for comparing health status across populations and time periods. *Fertility rate* - The **fertility rate** measures the average number of children born to women of reproductive age, influencing future population size and age structure. - While important for demographic planning and population projections, it doesn't directly provide insights into the immediate health challenges or mortality burden of a population. *Morbidity rate* - The **morbidity rate** quantifies the incidence or prevalence of disease in a population, reflecting the disease burden. - Although crucial for understanding health problems and planning healthcare services, it is considered secondary to mortality as a vital statistic since mortality represents the ultimate health outcome. *Birth rate* - The **birth rate** quantifies the number of live births per 1,000 people in a year, contributing to population growth and demographic trends. - Like the fertility rate, it is essential for understanding natality patterns but offers less insight into the overall health status and survival of a population compared to the mortality rate.

Q: Which of the following infectious diseases has the highest proportion of asymptomatic chronic carriers?

Hepatitis B. ***Hepatitis B*** - **Hepatitis B** infection has a significant proportion of **chronic asymptomatic carriers**, particularly when infection occurs perinatally or in early childhood. - In adults, approximately **5% develop chronic infection** after acute exposure, and many of these chronic carriers remain asymptomatic while maintaining infectivity. - Chronic carriers can harbor the virus for years or decades without clinical symptoms, making them an important reservoir for transmission. - This is a major public health concern as asymptomatic carriers can unknowingly transmit the virus. *Measles* - **Measles** is highly contagious and typically presents with **symptomatic disease** in nearly all infected individuals. - Clinical features include characteristic maculopapular rash, cough, coryza, conjunctivitis, and Koplik's spots. - Asymptomatic infection is **extremely rare** with measles virus. *Diphtheria* - While **asymptomatic pharyngeal carriage** of *Corynebacterium diphtheriae* can occur, it is not the predominant pattern. - Clinical diphtheria typically presents with pseudomembrane formation, sore throat, and potential systemic toxin effects. - Carrier rates vary but are not as epidemiologically significant as with Hepatitis B. *Rabies* - **Rabies** is almost **100% symptomatic** once the virus reaches the central nervous system. - There is **no chronic asymptomatic carrier state** in humans. - Once clinical symptoms appear (encephalitis, hydrophobia, paralysis), the disease is virtually always fatal.

Q: Which of the following screening methods is primarily used under the National Tuberculosis Elimination Program (NTEP)?

Passive. ***Passive*** - Under the NTEP, **passive screening** involves individuals presenting to health facilities with symptoms suggestive of TB. - This method relies on **patient self-reporting** and healthcare provider suspicion, rather than active outreach. - Passive case finding is the **primary screening strategy** used across the general population in the NTEP framework. *Active* - **Active screening** involves community-based interventions to proactively identify individuals with TB, often in high-risk populations. - While active case finding is crucial for specific vulnerable groups (contacts, HIV patients, etc.), it is **not the primary screening method** under the standard NTEP framework for initial detection across the entire population. *Mass* - **Mass screening** involves testing large numbers of people in the general population, regardless of symptoms, to detect disease. - This is generally **cost-prohibitive** and not routinely implemented as a primary screening strategy for TB by the NTEP due to resource limitations and low yield in the general population. *None of the options* - **Passive screening** is indeed a primary method used under the NTEP, making this option incorrect. - The NTEP heavily relies on individuals seeking care when they experience symptoms, which aligns with the definition of passive case finding.
