Urban Health Practice Questions

Q: Urban Social Health Activist (USHA) workers are proposed to work for which population size?

1000-2500. ### Explanation **1. Why the Correct Answer is Right:** Under the **National Urban Health Mission (NUHM)**, the **Urban Social Health Activist (USHA)** is the urban counterpart of the rural ASHA. The USHA is a community frontline worker primarily selected from urban poor settlements (slums). According to NUHM guidelines, one USHA is proposed to cover a population of **1,000 to 2,500**, typically representing **200 to 500 households**. This smaller, concentrated ratio ensures that the USHA can effectively navigate the high-density environment of urban slums to facilitate immunization, antenatal care, and sanitation. **2. Why the Incorrect Options are Wrong:** * **Option B (2500-3500):** This range is too high for a single USHA. While some urban health posts cover larger areas, the specific USHA-to-population ratio is kept lower to ensure intensive outreach. * **Option C (4000-5000):** This population size is generally the target for an **Auxiliary Nurse Midwife (ANM)** in an urban setting (1 ANM per 5,000 population). * **Option D (5000-10000):** This is the population norm for an **Urban Health & Wellness Centre (U-HWC)** or an **Urban Primary Health Centre (U-PHC)** (which typically serves 30,000–50,000 people). **3. High-Yield Facts for NEET-PG:** * **ASHA (Rural):** 1 per 1,000 population (relaxed to 1 per habitation in hilly/tribal areas). * **USHA (Urban):** 1 per 1,000–2,500 population (200–500 households). * **Anganwadi Worker (AWP):** 1 per 400–800 population. * **Urban PHC:** Serves approximately 50,000 people. * **MAS (Mahila Arogya Samiti):** A community group of 10–20 women supported by the USHA to promote local health planning.

Q: A city is defined as having a population exceeding which of the following thresholds?

100,000. **Explanation** In the context of Urban Health and Demography in India, the classification of urban settlements is based on population size as defined by the Census of India. **1. Why Option A is Correct:** According to the Census of India, an urban area with a population of **100,000 (1 Lakh) or more** is officially classified as a **City** (also known as a Class I Town). This is a high-yield threshold for public health planning, as it determines the allocation of resources under the National Urban Health Mission (NUHM). **2. Why the Other Options are Incorrect:** * **Option B (500,000):** While this represents a large urban center, it does not mark the specific transition point from a "Town" to a "City" in demographic terminology. * **Option C (1,000,000):** A population of 1 million or more defines a **Metropolitan City** (or Million-plus city). While all metropolitan areas are cities, the baseline definition of a city starts at 100,000. * **Option D (1,500,000):** This figure does not correspond to a standard demographic classification in the Indian Census or WHO urban health guidelines. **High-Yield Clinical Pearls for NEET-PG:** * **Town:** An urban area with a population between 5,000 and 99,999. * **Mega City:** A city with a population of **10 million (1 Crore)** or more (e.g., Mumbai, Delhi). * **Urban Agglomeration:** A continuous urban spread constituting a town and its adjoining outgrowths. * **Statutory Town:** Any place with a municipality, corporation, cantonment board, or notified town area committee, regardless of population size. * **Census Town:** Must satisfy three criteria: Minimum population of 5,000; at least 75% of the male main working population engaged in non-agricultural pursuits; and a density of at least 400 persons per sq. km.

Q: Which of the following urban health posts is attached to a hospital for sterilization, MTP, and referral services?

Type D. In the context of the **Urban Revitalization Scheme**, Urban Health Posts (UHPs) are categorized based on the population they serve and the specific services they provide. **Explanation of the Correct Answer:** **Option D (Type D)** is the correct answer. Type D Urban Health Posts are designed to serve a population of **over 50,000**. Unlike smaller health posts, Type D units are specifically **attached to a hospital** (usually a district or sub-district hospital). This attachment allows them to function as a referral hub and provide specialized reproductive health services, including **Sterilization (Tubectomy/Vasectomy), Medical Termination of Pregnancy (MTP), and advanced referral services**. **Analysis of Incorrect Options:** * **Type A:** These are the smallest units, serving a population of less than **10,000**. They are primarily outreach-oriented with minimal infrastructure. * **Type B:** These serve a population between **10,000 and 25,000**. They focus on basic primary healthcare and immunization but lack surgical facilities. * **Type C:** These serve a population between **25,000 and 50,000**. While they offer more comprehensive primary care than Type A or B, they do not typically have the hospital-linked surgical capabilities required for MTP and sterilization. **High-Yield Clinical Pearls for NEET-PG:** * **Population Norms:** Remember the 10k / 25k / 50k thresholds for Types A, B, and C/D respectively. * **NUHM (National Urban Health Mission):** Under current NUHM guidelines, the standard unit is the **U-PHC (Urban Primary Health Centre)**, which serves approximately 50,000 people. * **Staffing:** A Type D post usually has a larger staff complement, including a Medical Officer and specialized nursing staff, to facilitate its role as a link between the community and the hospital.

Q: What is the quantitative requirement of water in urban areas per day?

150 liters per capita. ### Explanation **Correct Answer: C. 150 liters per capita** In Community Medicine, the quantitative requirement of water is determined by the environment and the level of development. According to the **Bureau of Indian Standards (BIS: 1172)** and the **Manual on Water Supply and Treatment**, the standard water requirement for an average urban area with a full sewerage system is **150 to 200 liters per capita per day (lpcd)**. The figure of **150 lpcd** is the benchmark used for planning urban water supply schemes in India. This volume accounts for domestic needs (drinking, cooking, bathing, flushing), as well as institutional and minor commercial requirements. **Analysis of Incorrect Options:** * **Option A (220 liters):** This exceeds the standard requirement for typical Indian urban settings. While some metropolitan cities may aim higher, it is not the standard benchmark for exams. * **Option B (100 liters):** This is generally considered the requirement for **urban areas without a sewerage system** or for smaller towns. It is insufficient for a fully functional urban infrastructure. * **Option D (300 liters):** This is an overestimation. Such high consumption is usually seen only in highly industrialized cities or developed Western nations. **High-Yield NEET-PG Pearls:** * **Rural Water Requirement:** The minimum requirement for rural areas (under the Jal Jeevan Mission) is **55 lpcd**. * **Basic Survival:** The absolute minimum water required for survival (physiological needs) is approximately **2–3 liters per day**, but for "basic hygiene," the WHO recommends at least **20 lpcd**. * **Water Quality:** Remember that quantity is secondary to quality; for urban supply, the residual chlorine should be **0.5 mg/L** after a contact time of 30 minutes.

Q: Which species of Anopheles is responsible for urban malaria?

An. stephensi. **Explanation:** The correct answer is **Anopheles stephensi**. **1. Why An. stephensi is correct:** *Anopheles stephensi* is the primary vector for **urban malaria** in India. Its unique ecological adaptation allows it to breed in artificial containers and man-made structures common in urban settings, such as overhead water tanks, cisterns, fountain pits, construction sites, and cooling towers. Unlike many other species, it thrives in clean, stagnant water found in close proximity to human dwellings, facilitating efficient transmission in densely populated cities. **2. Analysis of Incorrect Options:** * **An. culicifaciens:** This is the most important vector for **rural malaria** in India. It typically breeds in rainwater pools, irrigation channels, and borrow pits. * **An. fluviatilis:** This species is the major vector for **hilly/tribal malaria**. It prefers breeding in slow-moving streams and foot-hill seepages. * **An. pseudopunctipennis:** While a significant malaria vector in parts of the Americas (particularly in mountainous regions), it is not a primary vector for urban malaria in the Indian subcontinent. **3. High-Yield Clinical Pearls for NEET-PG:** * **Vector for Rural Malaria:** *An. culicifaciens* (Responsible for ~65% of cases in India). * **Vector for Hilly/Foot-hill Malaria:** *An. fluviatilis*. * **Vector for Coastal Malaria:** *An. sundaicus*. * **Urban Malaria Scheme (UMS):** Launched in 1971, it focuses on "Source Reduction" (larval control) because *An. stephensi* is highly adapted to domestic water storage. * **Biological Control:** Use of larvivorous fish like *Gambusia affinis* and *Poecilia reticulata* (Guppy) is a key strategy in urban malaria management.

Q: What is the population catered to by an urban health center?

50 thousand. **Explanation** In the context of the **National Urban Health Mission (NUHM)**, the primary tier of healthcare delivery in urban areas is the **Urban Primary Health Centre (U-PHC)**. **1. Why Option C is Correct:** According to NUHM guidelines, an **Urban Primary Health Centre (U-PHC)** is established to cater to a population of approximately **50,000**. These centers are strategically located to ensure accessibility, particularly for the urban poor and those living in listed or unlisted slums. Unlike rural PHCs, which serve 20,000–30,000 people, the U-PHC handles a higher population density typical of urban settings. **2. Why Other Options are Incorrect:** * **Option A (10 Lakh):** This represents the population criteria for a **Mega City** or the catchment area for tertiary care institutions/Medical Colleges. * **Option B (1 Lakh):** This is the population norm for an **Urban Community Health Centre (U-CHC)** in larger cities. In some setups, one U-CHC acts as a referral unit for every 4–5 U-PHCs. * **Option D (10 Thousand):** This does not correspond to a formal health center tier. However, under NUHM, one **ANM (Auxiliary Nurse Midwife)** is typically assigned to a population of **10,000** (covering roughly 2,000–2,500 households). **High-Yield Clinical Pearls for NEET-PG:** * **ASHA in Urban Areas:** One ASHA (Accredited Social Health Activist) serves **1,000–2,500** people (roughly 200–500 households). * **Anganwadi:** One Anganwadi center in an urban area covers a population of **400–800**. * **Rural vs. Urban PHC:** While a Rural PHC has 4–6 beds, a U-PHC is primarily for **outpatient (OPD) services** and does not typically have in-patient beds. * **Mahila Arogya Samiti (MAS):** A key community group under NUHM, usually formed for every **50–100 households** (250–500 population).

Q: For what population size is an urban Primary Health Centre (PHC) typically intended?

1 per 50,000. ***1 per 50,000***- This is the standard population norm recommended by the Government of India for establishing an **Urban Primary Health Centre (UPHC)**.- The UPHC acts as the first referral unit for basic health needs, providing comprehensive **primary healthcare services** to this specified population size.*1 per 100,000*- This population norm is typically associated with the establishment of a **Community Health Centre (CHC)** (or sometimes an Urban CHC), which serves as a secondary care unit.- A PHC is designed to serve a smaller, more manageable catchment area to ensure effective outreach and **service proximity**.*1 per 250,000*- This much larger population size is often used as the norm for establishing higher-level facilities like **Sub-District Hospitals** or specialized referral institutions.- Implementing a PHC model for 250,000 people would violate the principles of accessible and decentralized **primary healthcare**.*1 per 200,000*- This population size is substantially higher than the mandated coverage area of **50,000 for an urban PHC**.- Utilizing this norm would severely compromise the crucial indicators of quality and accessibility of **primary care** services within the urban context.

Q: An urban city has a population of 70,00,000, with 30 % residing in slum areas. According to NUHM (National Urban Health Mission) norms, how many Urban Primary Health Centres (UPHCs) are required for the slum population?

42. ***Option: 42 (Correct Answer)*** - The slum population is calculated as 30% of 70,00,000, which equals **21,00,000** (2.1 million). - The **NUHM norm** mandates one Urban Primary Health Centre (UPHC) for a population of **50,000** in urban slum areas. - Required UPHCs = 21,00,000 ÷ 50,000 = **42 UPHCs**. *Option: 22 (Incorrect)* - This figure would imply a required population coverage of approximately **1 UPHC per 95,455** people (21,00,000 ÷ 22 ≈ 95,455). - This significantly exceeds the threshold set by the NUHM for vulnerable slum populations (50,000). - This calculation represents a major **under-provision** of primary healthcare infrastructure contrary to public health guidelines for urban poor. *Option: 32 (Incorrect)* - This number would result from using a population norm of about **1 UPHC per 65,625** people (21,00,000 ÷ 32 ≈ 65,625). - This is higher than the standard **50,000** norm for UPHCs in slums. - Using this higher figure would reduce the accessibility and availability of health services required for high-density **slum populations**. *Option: 52 (Incorrect)* - This calculation uses the **lower limit** of the NUHM range: **1 UPHC per 40,000** population (21,00,000 ÷ 40,000 = 52.5 ≈ 52). - While the NUHM range is 40,000-50,000, the standard practice uses **50,000** as the coverage target (resulting in **42 UPHCs**). - Using 40,000 would provide more facilities but the standard norm for calculation purposes is 50,000.

Q: What is the adequate total per capita water requirement for urban domestic purposes?

100-150 Liters. ***100-150 Liters*** - This represents the **adequate total per capita water requirement** for urban domestic purposes according to Indian public health standards. - **135 LPCD (Liters Per Capita Per Day)** is the standard recommended by CPHEEO (Central Public Health and Environmental Engineering Organisation) for urban water supply in India. - This range adequately covers drinking, cooking, bathing, washing, sanitation, and other essential domestic needs in urban households. *150-200 Liters* - This range exceeds the **minimum adequate requirement** and often includes significant water wastage or distribution losses. - While some developed urban areas might plan for this level to account for system losses, it is **not the adequate domestic requirement** itself. - Represents higher consumption patterns rather than adequate baseline needs. *50-100 Liters* - This range represents **basic minimum needs** according to WHO standards but is generally considered **insufficient for adequate urban domestic purposes** in Indian context. - May be adequate for rural areas or emergency situations but doesn't fully meet urban household requirements including bathing, washing clothes, and other domestic activities. *200-250 Liters* - This significantly exceeds adequate requirements and indicates **excessive water consumption**. - Such high usage is neither sustainable nor necessary for meeting adequate domestic needs. - May reflect wasteful practices or inclusion of non-domestic uses.

Q: Most efficient anti-larval measure to prevent urban malaria is:

Cover overhead tank. ***Cover overhead tank*** - **Overhead tanks** are common breeding grounds for **Anopheles stephensi**, the primary vector for **urban malaria**. Covering them prevents mosquitoes from laying eggs. - This measure directly targets the **larval stage** of the mosquito, effectively reducing the mosquito population. *Clean drainage and sewage system* - While important for general sanitation and preventing other diseases, **drainage and sewage systems** are less significant breeding sites for the specific mosquito species causing urban malaria than overhead tanks. - **Anopheles stephensi** prefers clean water collections, not typically polluted drainage. *Cover pits* - Covering pits is a good measure to reduce mosquito breeding in general, but **pits** are not the most common or impactful breeding sites for the primary urban malaria vector. - This method may address some potential breeding spots but not the most efficient in the context of urban malaria. *Filling cesspools and ditches* - **Cesspools and ditches** often contain stagnant, sometimes contaminated, water, which is not the preferred breeding environment for **Anopheles stephensi**. - While beneficial for controlling other mosquito species and improving hygiene, it is not the most efficient anti-larval measure specifically against urban malaria.
