Question 31: According to the ICDS scheme, what is the recommended population range for establishing one Anganwadi centre in rural areas?
- A. 700-1000 (Urban)
- B. 1000-1500 (Urban high density)
- C. 300-800 (Hilly/Tribal areas)
- D. 400-800 (Rural) (Correct Answer)
Explanation: ***400-800 (Rural)*** - The **Integrated Child Development Services (ICDS)** scheme recommends one Anganwadi centre for a population of **400-800** in **rural areas**. - This is the **standard population norm** as per ICDS guidelines for establishing Anganwadi centres in typical rural settings. - This ensures adequate coverage and accessibility of ICDS services (nutrition, immunization, health check-ups, and preschool education) for mothers and children. *700-1000 (Urban)* - This population range (**700-1000**) is the standard norm for **urban areas**, not rural areas. - Urban areas have higher population density, hence a slightly larger population range is used per Anganwadi centre. - The question specifically asks about **rural areas**, making this option incorrect. *300-800 (Hilly/Tribal areas)* - This range (**300-800**) is designated for **hilly, difficult terrain, or specific tribal areas** where geographical challenges and scattered populations require lower population norms. - While this includes rural characteristics, it represents **special category areas**, not standard rural areas as asked in the question. *1000-1500 (Urban high density)* - A population target of **1000-1500** would be too high even for standard urban norms and doesn't align with official ICDS guidelines. - This is not applicable to **rural areas** as specified in the question.
Question 32: Which of the following statements about ASHA workers is NOT true?
- A. Local resident
- B. Informs about birth and deaths in her village to PHC
- C. Works per 1000 people of an area
- D. Education at least till 4th class or higher (Correct Answer)
Explanation: ***Education at least till 4th class or higher*** - This statement is **NOT true**. The educational qualification for an ASHA worker is typically stated as **8th class or higher**, not 4th class. - While flexibility may exist in some remote areas, the general guideline requires a higher level of foundational education. *Informs about birth and deaths in her village to PHC* - This is a true statement regarding an ASHA worker's responsibilities, as they are crucial for **community-level data collection** and reporting to the **Primary Health Center (PHC)**. - ASHAs play a vital role in health surveillance, including reporting **births, deaths, and disease outbreaks**. *Local resident* - This is a true characteristic of an ASHA worker; they must be a **resident of the village** they serve. - Being a local resident ensures **community trust**, cultural understanding, and accessibility to the population. *Works per 1000 people of an area* - This is a true statement outlining the typical **population coverage** for an ASHA worker. - ASHAs are typically appointed to serve a population of approximately **1000 people** in rural areas to ensure adequate reach and support.
Question 33: Which of the following is NOT a duty of an ASHA worker?
- A. Administering zero dose of DPT and OPV (Correct Answer)
- B. Assessing the success of national programs under ANM
- C. Primary screening for prevalence of non-communicable diseases
- D. All of the options
Explanation: ***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
Question 34: Swajaldhara programme is associated with:
- A. Provision of safe drinking water (Correct Answer)
- B. Provision of food supplements for destitute women
- C. Provision of relief for victim of sexual abuse
- D. Provision of health care for sick tribals
Explanation: ***Provision of safe drinking water*** - The **Swajaldhara programme** was launched by the Government of India in 2002 to accelerate coverage of **drinking water supply** in rural areas - Its primary objective was to ensure access to **safe and sustainable drinking water sources** through community participation and decentralized management - The program emphasized local ownership with communities contributing 10% of project costs *Provision of food supplements for destitute women* - Food security programs for women fall under separate social welfare schemes like ICDS and PDS - The **Swajaldhara programme** was specifically focused on **water supply infrastructure**, not nutrition *Provision of relief for victim of sexual abuse* - Relief for victims of sexual abuse is addressed through **justice and women's safety initiatives** (e.g., One Stop Centres, Nirbhaya Fund) - This is unrelated to the water supply mandate of Swajaldhara *Provision of health care for sick tribals* - Health care for tribal populations is managed through dedicated programs under the Ministry of Health and Family Welfare - Swajaldhara's scope was limited to **rural drinking water infrastructure**, not healthcare delivery
Question 35: Which of the following screening methods is primarily used under the National Tuberculosis Elimination Program (NTEP)?
- A. Active
- B. Passive (Correct Answer)
- C. Mass
- D. None of the options
Explanation: ***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.
Question 36: Which of the following statements about the Pneumococcal Polysaccharide Vaccine (PPV) is correct?
- A. Administered at birth
- B. Recommended for individuals with sickle cell disease (Correct Answer)
- C. Widely used in the general population
- D. Derived from live attenuated pneumococcal bacteria
Explanation: ***Recommended for individuals with sickle cell disease*** - Individuals with **sickle cell disease** are at significantly increased risk of severe and invasive **pneumococcal infections** due to **functional asplenia**. - The PPV is crucial for providing **prophylactic protection** against these life-threatening infections in this vulnerable population. *Administered at birth* - The **Pneumococcal Conjugate Vaccine (PCV)** is part of routine childhood immunizations and is administered at specific ages, but neither PCV nor PPV is given **at birth**. - **PCV** is typically given starting at **2 months of age**, while **PPV** is generally recommended for older children and adults at high risk. *Widely used in the general population* - The **Pneumococcal Conjugate Vaccine (PCV)** is widely used in the general *pediatric* population as part of routine immunization schedules. - The **Pneumococcal Polysaccharide Vaccine (PPV)** is primarily recommended for **adults 65 years and older** and individuals with certain **underlying medical conditions** or compromised immune systems, not the general population. *Derived from live attenuated pneumococcal bacteria* - The **PPV** is a **polysaccharide vaccine**, meaning it is composed of purified capsular polysaccharides from various serotypes of *Streptococcus pneumoniae*. - It is an **inactivated vaccine** and does not contain live attenuated bacteria; such a vaccine would be contraindicated in immunocompromised individuals.
Question 37: What distance from a water source defines a problem village according to the Government of India?
- A. > 0.5 km
- B. > 1 km
- C. > 1.6 km (Correct Answer)
- D. None of the options
Explanation: ***> 1.6 km*** - According to the **Government of India's criteria**, a village is designated as a **problem village** if its residents have to travel more than **1.6 kilometers** to access a safe and assured source of drinking water. - This definition is crucial for identifying areas that require specific interventions and programs to improve water access. *> 0.5 km* - While a distance of 0.5 km might be considered inconvenient, it does not meet the **official threshold** set by the Government of India for categorizing a village as "problematic" regarding water access. - This distance is typically much shorter than the criteria used for policy and intervention planning. *> 1 km* - A distance of 1 km, like 0.5 km, falls short of the **established benchmark** of 1.6 km defined by the Government of India for identifying a problem village. - Although it represents a significant walk, it does not trigger the specific **policy responses** associated with problem village status. *None of the options* - This option is incorrect because **1.6 km** is indeed the specific distance recognized by the Government of India for defining a problem village in terms of water source accessibility. - The other options are incorrect as they do not match the official criteria.
Question 38: Pneumonic plague is spread by:
- A. Direct contact with infected tissue
- B. Bite of infected flea
- C. Ingestion of contaminated food
- D. Droplet infection (Correct Answer)
Explanation: ***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.
Question 39: What is the most common mode of transmission of HIV?
- A. Occupational exposure (needle stick injury)
- B. Perinatal transmission (mother to child)
- C. Sexual contact (Correct Answer)
- D. Transmission via blood and blood products
Explanation: ***Sexual contact*** - **Unprotected sexual intercourse**, both heterosexual and homosexual, is overwhelmingly the most common way HIV is transmitted globally. - The virus can be exchanged through **bodily fluids** such as semen, vaginal fluids, and rectal fluids during sexual activity. - Accounts for approximately **80% of new HIV infections** worldwide. *Occupational exposure (needle stick injury)* - While a recognised mode of transmission, **needle stick injuries** account for a very small percentage of total HIV infections, primarily affecting healthcare workers. - The risk of transmission per exposure is relatively low (approximately **0.3%**), especially compared to sexual contact. *Perinatal transmission (mother to child)* - **Mother-to-child transmission** can occur during pregnancy, childbirth, or breastfeeding. - Although significant, especially in resource-limited settings, global efforts and **PMTCT programs** have resulted in a significant reduction in this type of transmission. *Transmission via blood and blood products* - This mode was once a major concern but is now extremely rare in countries with robust **blood screening programs**. - While sharing contaminated needles among **intravenous drug users** remains a risk, transfusion-related HIV is largely controlled.
Question 40: Which of the following is not a recognized transmission route for amoebiasis?
- A. Sexual transmission
- B. Blood and blood products
- C. Vector transmission (Correct Answer)
- D. Fecal-oral route
Explanation: ***Vector transmission*** - Amoebiasis, caused by *Entamoeba histolytica*, is primarily an **intestinal infection** transmitted through the **fecal-oral route**. - Its life cycle **does not involve any arthropod vector** (e.g., mosquito, tick, fly) for transmission. - This is the **only route among the options that is definitively NOT recognized** for amoebiasis transmission. *Sexual transmission* - Amoebiasis **can be transmitted** through **oral-anal sexual contact**, particularly documented in men who have sex with men (MSM). - This represents an **indirect fecal-oral transmission** route and is a recognized mode of spread. *Blood and blood products* - While *E. histolytica* can disseminate to cause **amoebic liver abscesses** and rarely systemic disease, transmission via blood transfusion is **extremely rare and not well-documented**. - However, theoretically possible in cases of parasitemia during invasive disease. - Unlike vector transmission, this cannot be definitively ruled out as "not recognized." *Fecal-oral route* - This is the **primary and most important transmission route** for amoebiasis. - Infection occurs through ingestion of **cysts** from contaminated food, water, or through direct person-to-person contact with poor hand hygiene.
