Practice Indian Medical PG questions for Rural Water Supply and Sanitation. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Rural Water Supply and Sanitation Indian Medical PG Question 1: The Roll Back Malaria programme focused mainly on
- A. IEC campaigns for community awareness
- B. Insecticide treated bed nets (Correct Answer)
- C. Development of larvivorous fishes for eradication of larvae.
- D. Presumptive treatment of malaria case
Rural Water Supply and Sanitation Explanation: ***Insecticide treated bed nets***
- The **Roll Back Malaria (RBM)** program, launched in 1998, focused significantly on key interventions including the promotion and distribution of **insecticide-treated nets (ITNs)**.
- ITNs are highly effective in **preventing mosquito bites**, thus reducing malaria transmission, especially in vulnerable populations.
*IEC campaigns for community awareness*
- While **Information, Education, and Communication (IEC)** campaigns are crucial for health programs, they were a supportive component rather than the primary focus of RBM's core intervention strategy.
- RBM emphasized **tangible interventions** with direct impact on disease transmission.
*Development of larvivorous fishes for eradication of larvae*
- The use of **larvivorous fish** is a form of biological control, which is typically part of **integrated vector management** but not the central pillar of RBM's strategy.
- RBM prioritized interventions with **broad, immediate impact** across larger populations.
*Presumptive treatment of malaria case*
- **Presumptive treatment** (treating based on symptoms without laboratory confirmation) was an important aspect of early malaria control but not the main strategic thrust of the RBM initiative.
- RBM's primary focus was on **prevention and rapid diagnosis/treatment** using effective antimalarials, and vector control strategies.
Rural Water Supply and Sanitation Indian Medical PG Question 2: Which of the following procedures is not typically covered by the National Programme for Control of Blindness (NPCB) for reimbursement of surgery done by a non-governmental organization (NGO) eye hospital?
- A. Cataract surgery
- B. Pan retinal photocoagulation for diabetic retinopathy
- C. Syringing and probing of the nasolacrimal duct (Correct Answer)
- D. Trabeculectomy surgery
Rural Water Supply and Sanitation Explanation: ***Syringing and probing of the nasolacrimal duct***
- While important for lacrimal drainage issues, procedures like **syringing and probing** are generally considered minor and less vision-restoring compared to the major surgeries targeted by the **NPCB**.
- The **NPCB** focuses on interventions for leading causes of blindness, primarily **cataract** and other significant vision-threatening conditions, which this procedure typically isn't.
*Cataract surgery*
- **Cataract surgery** is a cornerstone of the **NPCB's** efforts, as cataracts are the leading cause of reversible blindness.
- Reimbursement for **cataract surgery** is a primary objective to improve access and reduce the burden of blindness.
*Pan retinal photocoagulation for diabetic retinopathy*
- **Diabetic retinopathy** is a major cause of preventable blindness, and **pan retinal photocoagulation (PRP)** is a key intervention to preserve vision.
- The **NPCB** includes procedures for **diabetic retinopathy** management due to its significant public health impact.
*Trabeculectomy surgery*
- **Trabeculectomy** is a surgical procedure for **glaucoma**, which is another significant cause of irreversible blindness.
- The **NPCB** includes interventions for **glaucoma** given its severe vision-threatening nature and the need for surgical management in many cases.
Rural Water Supply and Sanitation Indian Medical PG Question 3: What is the correct method for collecting water for bacteriological examination during a disease outbreak?
- A. Collect water from already leaking taps
- B. Collect water from a tap after letting it flow for at least 1 minute to ensure freshness (Correct Answer)
- C. Collect from a gentle stream of water to avoid splashing
- D. Before collecting, let water flow for at least 1 minute
Rural Water Supply and Sanitation Explanation: ***Correct: Collect water from a tap after letting it flow for at least 1 minute to ensure freshness***
- This is the **standard protocol** for bacteriological water sampling as per WHO and APHA guidelines
- Flushing for **at least 1 minute** removes stagnant water from pipes and tap fixtures that may contain biofilms or non-representative bacterial contamination
- This ensures the sample represents the **actual water supply** rather than water sitting in pipes
- The complete statement includes both the flushing step AND the collection, making it a **complete procedure**
*Incorrect: Collect water from already leaking taps*
- Leaking taps contain **stagnant water** with biofilm accumulation that is not representative of the main water supply
- Continuous dripping allows **external contamination** from air and surrounding surfaces
- Does not follow standard water sampling protocols
*Incorrect: Collect from a gentle stream of water to avoid splashing*
- While avoiding splashing is important to prevent external contamination, this option **omits the critical flushing step**
- Without prior flushing, the sample may contain bacteria from **stagnant water in pipes** rather than the actual supply
- Incomplete methodology
*Incorrect: Before collecting, let water flow for at least 1 minute*
- While this describes the flushing step correctly, it is **incomplete as a method**
- It states "before collecting" but doesn't describe the actual collection process
- The question asks for the "correct method" which should include the complete procedure, not just a preparatory step
Rural Water Supply and Sanitation Indian Medical PG Question 4: Which of the following statements regarding diagnosis of malaria are true?
- A. Thin blood film is used to determine parasite concentration.
- B. As the sensitivity of microscopy is low, it is useful to detect parasite load at high concentrations only.
- C. Jaswant Singh Bhattacharya (JSB) Stain is used. (Correct Answer)
- D. Thick blood film is used to detect plasmodium species causing infection.
Rural Water Supply and Sanitation Explanation: ***Correct: Jaswant Singh Bhattacharya (JSB) Stain is used.***
- **JSB stain** is a rapid and effective method for staining malaria parasites in blood films, particularly in resource-limited settings where traditional Romanowsky stains might not be readily available.
- Its quick staining time (3-5 minutes) and ease of use make it valuable for prompt diagnosis of malaria.
- This is the **most clearly correct** statement as JSB stain is definitively used in malaria diagnosis.
*Thick blood film is used to detect plasmodium species causing infection.*
- A **thick blood film** is primarily used for **detecting** the presence of malaria parasites due to its higher sensitivity in screening larger volumes of blood (concentrates parasites 20-40 times).
- However, it is **not ideal for species identification** due to distorted RBC morphology and lysed red blood cells.
- The statement is **misleading** - while thick films detect parasites, they are not the preferred method for determining the **specific species**.
*Thin blood film is used to determine parasite concentration.*
- This statement is **technically correct** - thin blood films ARE used to determine parasite concentration (parasitemia) and for speciation.
- However, in the context of this question, **JSB stain is the better answer** as it is more specifically and uniquely associated with malaria diagnosis, whereas thin films have broader applications.
- Thin films allow accurate quantification of parasitemia (parasites/µL or percentage of infected RBCs) and species identification due to preserved RBC morphology.
*As the sensitivity of microscopy is low, it is useful to detect parasite load at high concentrations only.*
- **Incorrect** - Microscopy, particularly with thick blood films, has **high sensitivity** and is considered the gold standard for malaria diagnosis.
- Microscopy can detect parasites at concentrations as low as **50-100 parasites/µL** (approximately 0.001% parasitemia).
- While operator-dependent, it is certainly not limited to detecting parasites only at high concentrations.
Rural Water Supply and Sanitation Indian Medical PG Question 5: 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
Rural Water Supply and Sanitation 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
Rural Water Supply and Sanitation Indian Medical PG Question 6: Which irrigation solution is commonly used in endodontic procedures?
- A. EDTA
- B. Chlorhexidine
- C. Saline
- D. Sodium hypochlorite (Correct Answer)
Rural Water Supply and Sanitation Explanation: ***Sodium hypochlorite***
- **Sodium hypochlorite (NaOCl)** is the most widely used irrigant due to its potent **antimicrobial activity** and ability to dissolve **necrotic tissue** and organic debris within the root canal system.
- Its efficacy in cleaning and disinfecting makes it critical for successful endodontic treatment.
*EDTA*
- **EDTA (ethylenediaminetetraacetic acid)** is a **chelating agent** primarily used to remove the **smear layer** and inorganic debris from the canal walls.
- While it helps in canal preparation, it lacks antimicrobial properties and the ability to dissolve organic tissue, so it is not used as the primary or sole irrigant.
*Chlorhexidine*
- **Chlorhexidine (CHX)** is an **antimicrobial agent** used as an endodontic irrigant, particularly when sodium hypochlorite is contraindicated or as an adjunctive rinse.
- However, it does not dissolve organic tissue or the smear layer, making it less effective as a primary irrigant compared to sodium hypochlorite.
*Saline*
- **Saline (0.9% sodium chloride)** is a biocompatible solution used for flushing and rinsing but has **no antimicrobial properties** and cannot dissolve tissue or remove the smear layer.
- It is often used as an intermediary rinse between different irrigants to prevent adverse chemical reactions or as a final rinse.
Rural Water Supply and Sanitation Indian Medical PG Question 7: 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)
Rural Water Supply and Sanitation 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
Rural Water Supply and Sanitation Indian Medical PG Question 8: Which among the following is the BEST irrigating fluid during ECCE?
- A. Ringer lactate
- B. Normal saline
- C. Balanced salt solution
- D. Balanced salt solution + glutathione (Correct Answer)
Rural Water Supply and Sanitation Explanation: ***Balanced salt solution + glutathione***
- **Balanced salt solution with glutathione** is considered the best irrigating fluid for ECCE because it closely mimics the **natural aqueous humor**, maintaining corneal endothelial cell health and viability during surgery.
- The addition of **glutathione** provides an antioxidant effect, protecting the corneal endothelium from oxidative stress and maintaining its metabolic function during prolonged irrigation.
*Ringer lactate*
- While **Ringer's lactate** is a balanced electrolyte solution, it lacks the specific components and buffering capacity present in specialized ophthalmic irrigating solutions.
- It does not contain **glutathione** or other agents crucial for maintaining corneal endothelial viability and function during intraocular surgery.
*Normal saline*
- **Normal saline (0.9% NaCl)** lacks essential ions (calcium, magnesium, potassium) and appropriate pH buffering required for intraocular use.
- Its use can lead to **corneal edema** and endothelial cell damage due to ionic imbalance and the absence of protective components found in balanced salt solutions.
*Balanced salt solution*
- A **plain balanced salt solution (BSS)** is a significant improvement over normal saline or Ringer's lactate as it is physiologically balanced for intraocular use, containing essential electrolytes.
- However, it lacks the **antioxidant properties of glutathione**, which provides superior protection to corneal endothelial cells during extended surgical procedures.
Rural Water Supply and Sanitation Indian Medical PG Question 9: Which of the following waste disposal methods provides the greatest benefit for soil enrichment?
- A. Incineration
- B. Controlled tipping
- C. Composting (Correct Answer)
- D. Dumping
Rural Water Supply and Sanitation Explanation: ***Composting***
- **Composting** breaks down organic waste into **humus**, a nutrient-rich material that significantly improves soil structure, water retention, and fertility.
- It enriches soil by adding essential **macronutrients** (e.g., nitrogen, phosphorus, potassium) and micronutrients, fostering healthy plant growth and microbial activity.
*Incineration*
- **Incineration** involves burning waste at high temperatures, reducing its volume and generating energy, but it destroys all organic matter.
- While it can reduce landfill burden, it offers no direct benefit to **soil enrichment** and may release air pollutants.
*Controlled tipping*
- **Controlled tipping**, or sanitary landfilling, involves burying waste in an engineered site to minimize environmental impact.
- Although some organic decomposition occurs, it is often anaerobic and produces **methane**, with limited direct benefit for **soil enrichment** in the immediate vicinity or for agricultural use.
*Dumping*
- **Dumping** refers to the uncontrolled disposal of waste in open areas, which is environmentally harmful and poses significant public health risks.
- This method pollutes soil and water, attracts pests, and offers no benefits for **soil enrichment**; instead, it degrades soil quality.
Rural Water Supply and Sanitation Indian Medical PG Question 10: Swajaldhara yojana is to provide -
- A. Pension
- B. Nutrition
- C. Sickness Benefits
- D. Water (Correct Answer)
Rural Water Supply and Sanitation Explanation: ***Water***

- It emphasizes **decentralized, demand-driven, and community-managed water supply systems**, promoting local ownership and sustainability.
*Pension*
- Schemes related to **pension** provision are generally managed under different government programs, such as the National Pension System or specific social security schemes for the elderly.
- These programs focus on providing **financial security** during retirement, which is distinct from water supply.
*Nutrition*
- Government programs focused on **nutrition** often include initiatives like the Integrated Child Development Services (ICDS) or Mid-Day Meal Scheme.
- These programs aim to address **malnutrition** and food security, which is not the primary objective of Swajaldhara Yojana.
*Sickness Benefits*
- **Sickness benefits** are typically provided through social security schemes or health insurance programs, such as the Employees' State Insurance Scheme (ESIS).
- These benefits aim to provide **financial support** during periods of illness, which is unrelated to rural water supply.
