Urban Slum Health Indian Medical PG Practice Questions and MCQs
Question 1: Which of the following is a criterion for overcrowding?
- A. Floor space (Correct Answer)
- B. Sex separation
- C. Door and window
- D. Number of persons
Explanation: ***Floor space*** - **Floor space per person** is the most fundamental criterion for assessing overcrowding, as inadequate space leads to poor ventilation and increased disease transmission. - Public health guidelines (WHO, Indian standards) specify a **minimum floor area** per occupant (typically 40-50 sq ft per person) to prevent overcrowding and associated health risks. - This is a **direct quantitative measure** that objectively defines overcrowding. *Sex separation* - **Sex separation** is a criterion for privacy, decency, and housing quality, particularly in shared living spaces, but not a measure of physical overcrowding. - It relates to **social and cultural considerations** rather than occupancy density or physical capacity of a dwelling. *Door and window* - The presence and adequacy of **doors and windows** are criteria for ventilation, natural light, and safety, contributing to overall habitability. - While important for health, these features define **housing quality** rather than **overcrowding**, which is primarily based on occupant-to-space ratios. *Number of persons* - The **number of persons alone** is insufficient as a criterion without spatial context. - While **persons per room** (>2 persons/room) is a valid overcrowding criterion, the absolute number of persons must be considered **in relation to available space** (floor area or rooms) to be meaningful. - A large family in a spacious dwelling is not overcrowded, whereas few persons in a confined space could be, illustrating that **person count alone cannot define overcrowding**.
Question 2: Which of the following is a primary determinant of undernutrition?
- A. Infections
- B. Low birth weight
- C. Less water intake
- D. Low food intake (Correct Answer)
Explanation: ***Low food intake*** - **Low food intake**, meaning insufficient consumption of food, directly leads to a lack of essential nutrients and energy, which is the most fundamental cause of **undernutrition**. - This can be due to various factors like poverty, food insecurity, poor dietary choices, or conditions causing appetite loss, all converging on inadequate nutrient supply. *Low birth weight* - **Low birth weight** is often a *consequence* or a *marker* of undernutrition in the mother or during fetal development, rather than a primary determinant of subsequent undernutrition itself. - While it increases the risk of health problems, including future undernutrition, it's not the initial cause of nutrient deficiency. *Infections* - **Infections** can *exacerbate* undernutrition by increasing nutrient requirements, impairing nutrient absorption, and causing appetite loss. - However, infections are often risk factors or consequences of an already weakened nutritional state, rather than the initial, direct cause of a nutrient deficit. *Less water intake* - **Less water intake** primarily leads to **dehydration**, which affects overall health and nutrient transport but is not a direct cause of **undernutrition** (i.e., a lack of essential calories, proteins, vitamins, and minerals). - While hydration is crucial for health, it is distinct from the intake of macronutrients and micronutrients that define nutritional status.
Question 3: In all of the following diseases chronic carriers are found except:
- A. Typhoid
- B. Gonorrhoea
- C. Measles (Correct Answer)
- D. Hepatitis B
Explanation: ***Measles*** - Measles is caused by a **highly contagious virus** and typically results in an acute illness followed by lifelong immunity; it does not establish a chronic carrier state. - Individuals either recover completely or succumb to the disease, without becoming asymptomatic carriers who can transmit the virus for extended periods. *Typhoid* - **Chronic carriers** of *Salmonella Typhi* can harbor the bacteria in their **gallbladder** or urinary tract for years, shedding it in their feces or urine. - These carriers, despite showing no symptoms themselves, can transmit the infection to others, posing a significant public health risk. *Gonorrhoea* - Some individuals infected with *Neisseria gonorrhoeae* can be **asymptomatic carriers**, particularly women, and can transmit the infection without knowing they are infected. - While generally not considered "chronic" in the same way as typhoid or hepatitis B, asymptomatic carriage can persist for several weeks or months. *Hepatitis B* - Many individuals infected with the **Hepatitis B virus (HBV)**, especially if infected during infancy or early childhood, can become **chronic carriers**. - These chronic carriers can continue to transmit the virus and are at increased risk for developing serious liver diseases such as **cirrhosis** and **hepatocellular carcinoma**.
Question 4: Which of the following is an example of indirect transmission in communicable diseases?
- A. Transplacental (vertical)
- B. Soil (Correct Answer)
- C. Respiratory
- D. STD
Explanation: ***Soil*** - **Indirect transmission** involves an intermediate vehicle or vector, like **contaminated soil**. - Pathogens in soil, such as *Clostridium tetani*, can enter the body through wounds. *Transplacental (vertical)* - This is a form of **direct transmission** where pathogens pass from mother to fetus during pregnancy. - Examples include HIV, syphilis, and rubella, which are directly transferred through the placenta. *Respiratory* - This is a form of **direct transmission** through airborne droplets or aerosols expelled by an infected person. - Diseases like influenza and tuberculosis spread directly from person to person via respiratory secretions. *STD* - **Sexually transmitted diseases (STDs)** involve **direct transmission** through sexual contact between individuals. - Pathogens are transferred directly from an infected person to a susceptible person during intercourse.
Question 5: According to the National Health Policy, primary urban health centers should be designated for a population of:
- A. 30,000 people
- B. 50,000 people (Correct Answer)
- C. 10,000 people
- D. 1,000,000 people
Explanation: **50,000 people** - According to the **National Health Policy (NHP)**, specifically in the context of urban healthcare planning, a **primary urban health center (PUHC)** is designed to cater to a population of approximately **50,000 individuals**. - This population norm ensures adequate access to basic health services for urban populations, considering the higher population density and varied health needs in urban settings compared to rural areas. *30,000 people* - This population norm is typically associated with a **Primary Health Centre (PHC)** in **plain areas** according to the NHP for **rural populations**. - Urban health centers are designed for a larger population base due to differences in population density and healthcare infrastructure. *10,000 people* - This figure more closely aligns with the population norm for a **Sub-Centre** in plain areas, which is the most peripheral and first contact point between the primary healthcare system and the community. - A primary urban health center serves a significantly larger population than a sub-centre. *1,000,000 people* - A population of **one million people** would require a much larger health infrastructure, typically involving multiple hospitals, specialized centers, and a network of primary and secondary care facilities, rather than a single primary urban health center. - This figure is far too large for the designated population coverage of a primary urban health center.
Question 6: Which of the following statements about a primary health centre (PHC) is incorrect?
- A. Tertiary care surgical procedures (Correct Answer)
- B. Caters about 20,000- 30,000 people
- C. Provide water and sanitation and basic health requirements
- D. There is one medical officer and one staff nurse
Explanation: ***Tertiary care surgical procedures*** - Primary Health Centres (PHCs) are designed to provide **basic and essential healthcare services** at the community level, not advanced surgical interventions. - **Tertiary care procedures**, which involve complex surgeries or specialized treatments, are typically performed at **district hospitals** or super-specialty hospitals. - PHCs focus on **primary healthcare** including outpatient care, basic laboratory services, immunization, maternal and child health services, and health education. *Caters about 20,000-30,000 people* - This statement is **correct** regarding the population coverage of a PHC in rural areas. - According to IPHS norms, a PHC serves **20,000-30,000 population** in plain areas and **30,000 population** in hilly/tribal/difficult areas. - The PHC acts as the **first point of contact** for individuals seeking health services in a defined geographical area. *Provide water and sanitation and basic health requirements* - This is a **correct** statement, as PHCs are responsible for promoting health and preventing disease through community-level interventions. - They ensure access to **safe water, sanitation, and essential primary healthcare**. - PHCs focus on improving **public health determinants** alongside providing clinical services through health education and environmental health activities. *There is one medical officer and one staff nurse* - This statement is **correct** and describes the **minimum staffing pattern** at PHCs according to Indian Public Health Standards (IPHS). - A standard PHC has at least **1 Medical Officer, 1 Staff Nurse, and support staff** including ANMs (Auxiliary Nurse Midwives) who work at sub-centers. - Additional staff may be present depending on whether it's a 4-bedded or 6-bedded PHC.
Question 7: What is the adequate total per capita water requirement for urban domestic purposes?
- A. 150-200 Liters
- B. 200-250 Liters
- C. 50-100 Liters
- D. 100-150 Liters (Correct Answer)
Explanation: ***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.
Question 8: Which of the following is NOT a key intervention implemented under the Reproductive and Child Health (RCH) programme?
- A. Immunization
- B. ORS therapy
- C. Vitamin A supplementation
- D. Management of hypertension (Correct Answer)
Explanation: ***Management of hypertension*** - While important for overall health, the **management of non-communicable diseases (NCDs)** like hypertension is not a primary, direct focus of the **Reproductive and Child Health (RCH) programme**. - RCH programs primarily target interventions related to women's reproductive health, safe motherhood, and child survival. *Immunization* - **Immunization** is a cornerstone intervention of the RCH program, crucial for preventing major childhood diseases and improving child survival rates. - It directly contributes to reducing **infant and child mortality** by protecting against vaccine-preventable diseases. *ORS therapy* - **Oral Rehydration Solution (ORS) therapy** is a key intervention within the RCH program aimed at reducing child mortality due to diarrheal diseases. - It is effective in treating **dehydration** caused by diarrhea, a common cause of death in young children. *Vitamin A supplementation* - **Vitamin A supplementation** is an essential RCH intervention, particularly for children, to prevent **vitamin A deficiency**. - It plays a vital role in **boosting immunity**, preventing blindness, and reducing the severity of common childhood infections.
Question 9: What is the primary health concern addressed by the Rashtriya Bal Swasthya Karyakram (RBSK)?
- A. Adult chronic diseases
- B. Elderly health
- C. Non-communicable diseases in the youth
- D. Comprehensive healthcare for children from birth to 18 years (Correct Answer)
Explanation: **Comprehensive healthcare for children from birth to 18 years** - The **Rashtriya Bal Swasthya Karyakram (RBSK)** is a national program explicitly designed to provide comprehensive health screening and early intervention for 0-18 year-olds - Its focus is on detecting and managing the **4 D's**: Defects at birth, Deficiencies, Diseases, and Developmental delays - The program provides regular health check-ups, early detection of health conditions, referral for treatment, and promotes healthy development across this critical age group *Adult chronic diseases* - While public health initiatives address adult chronic diseases, they are not the primary focus of the **RBSK** program, which targets a younger demographic - Programs like the **National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases & Stroke (NPCDCS)** are more aligned with adult chronic disease management *Elderly health* - **RBSK** is specifically focused on the health of children and adolescents, not the elderly population - **National Programme for Healthcare of the Elderly (NPHCE)** is a dedicated initiative for elderly health *Non-communicable diseases in the youth* - While **RBSK** does address some non-communicable diseases (NCDs) through early detection and management, its scope is much broader, encompassing all 4 D's - RBSK aims for **holistic child health** rather than exclusively targeting NCDs in youth, which is a subset of its overall mandate
Question 10: Which of the following is the vector for Zika virus?
- A. Anopheles
- B. Culex tritaeniorhynchus
- C. Phlebotomus papatasi
- D. Aedes aegypti (Correct Answer)
Explanation: ***Aedes aegypti*** - This mosquito species is the primary **vector** responsible for transmitting the **Zika virus** to humans. - It also transmits other arboviruses, including **dengue**, **chikungunya**, and **yellow fever**. *Anopheles* - This genus of mosquitoes is primarily known as the vector for **malaria parasites**. - While it can transmit some other pathogens, **Zika virus** is not typically associated with *Anopheles* species. *Culex tritaeniorhynchus* - This mosquito species is a significant vector for **Japanese encephalitis virus** in Asia. - It is not the primary or recognized vector for **Zika virus**. *Phlebotomus papatasi* - This is a species of **sandfly**, not a mosquito, and acts as a vector for **Leishmania parasites** and **Sandfly fever virus**. - It is not involved in the transmission of **Zika virus**.
