NEET-PG 2012 - Community Medicine PYQs Practice Questions

Q: Which of the following is NOT a key intervention implemented under the Reproductive and Child Health (RCH) programme?

Management of hypertension. ***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.

Q: IUCD lasting for 10 years is a:

CuT - 380A. ***CuT - 380A*** - The **CuT-380A** is a copper-containing intrauterine device (IUD) specifically designed for a highly effective contraceptive duration of **10 years**. - Its mechanism involves the continuous release of copper ions, which create a hostile uterine environment for sperm and ova, preventing fertilization. *Progestase* - **Progestasert** (or Progestasert system) is a progesterone-releasing IUD that has a much **shorter duration of action**, typically around **1 year**. - Its contraceptive effect relies on the local release of progesterone, which thickens cervical mucus and thins the endometrial lining. *CuT - 220 (shorter duration)* - The **CuT-220** is an older generation copper IUD with a **shorter period of efficacy**, typically around **3 to 4 years**. - It contains a smaller surface area of copper compared to the CuT-380A, hence its shorter lifespan. *Nova T (shorter duration)* - **Nova T** is a copper IUD that is effective for a duration of **5 years**, making it a shorter-acting option compared to the CuT-380A. - While also copper-based, its design and total copper content allow for a more limited period of effectiveness.

Q: Who is recognized as the father of public health?

John Snow. ***John Snow*** - **John Snow** is widely recognized as the **father of epidemiology and modern public health** for his groundbreaking work in identifying the source of the 1854 Broad Street cholera outbreak in London. - He used **mapping and statistical analysis** to demonstrate that cholera was a waterborne disease, challenging the prevailing miasma theory. - His scientific approach to investigating disease patterns established the foundation for modern epidemiological methods and evidence-based public health interventions. *Edward Jenner* - **Edward Jenner** is known for his pioneering work on the **smallpox vaccine** in the late 18th century, which laid the foundation for immunology. - While his contributions were crucial for preventive medicine, his focus was on vaccination rather than broader public health and epidemiological investigation. *James Lind* - **James Lind** was a Scottish naval surgeon who conducted one of the first recorded controlled clinical trials, demonstrating that **citrus fruits cured scurvy** in the mid-18th century. - His work was significant for nutritional science and clinical trial methodology, but not for the comprehensive scope of public health and disease investigation. *Frederick Griffith* - **Frederick Griffith** was a British bacteriologist whose 1928 experiment with *Streptococcus pneumoniae* demonstrated the process of **bacterial transformation**, suggesting that genetic material could be transferred. - His work was foundational for molecular biology and genetics, not directly related to public health practices or epidemiology.

Q: What is the simplest and most commonly used measure of mortality?

Crude death rate. ***Crude death rate*** - This is the simplest and most commonly used measure because it reflects the **total number of deaths** in a population over a specified period, relative to the mid-period population. - Its calculation requires only the total number of deaths and the total population size, making it easily accessible and widely applicable for **general mortality comparisons**. *Case fatality rate* - This measures the **proportion of individuals diagnosed with a specific disease** who die from that disease, rather than overall mortality in a population. - It is often used to assess the **severity of a disease** and is not a general measure of mortality. *Proportional mortality rate* - This indicates the **proportion of all deaths due to a specific cause** or age group, rather than the overall death rate in the population. - It does not represent the absolute risk of dying and is influenced by the prevalence of other causes of death. *Specific death rate* - This measure calculates the death rate for a **particular subgroup** (e.g., age-specific, cause-specific, or sex-specific), making it more detailed but not the simplest or most commonly used overall measure. - While more precise for specific analyses, it requires more granular data than the crude death rate.

Q: Calcium requirement above the normal during the first six months of lactation is -

600 mg/day. ***600 mg/day*** - The increased calcium requirement during the first six months of lactation is primarily due to the significant amount of calcium secreted in **breast milk** for infant bone development. - During lactation, approximately **210-300 mg of calcium per day** is lost through breast milk, and considering **absorption efficiency** and maintaining maternal **bone density**, an additional **600 mg/day** above baseline requirements is recommended. - This additional intake helps meet the demands of milk production and prevent maternal bone demineralization during the period of **peak lactation**. *400 mg/day* - While calcium needs are elevated in lactation, an additional **400 mg/day** is insufficient to fully compensate for the calcium loss through breast milk during the initial, high-volume milk production phase. - This amount does not adequately account for both milk calcium content and the need to maintain maternal bone health during the first six months of lactation. *550 mg/day* - This increment is close but is generally considered slightly below the recommended additional intake for optimal maternal health and infant nutrition during **peak lactation**. - Adequate calcium intake is crucial as insufficient levels can lead to a negative calcium balance and increased risk of maternal **osteoporosis**. *75 mg/day* - An additional **75 mg/day** is a negligible increase and is far too low to meet the substantial calcium demands during the first six months of lactation. - This amount would be grossly inadequate considering that lactating mothers lose approximately **210-300 mg of calcium per day** into breast milk alone, not accounting for maternal physiological needs.
