Q: The major contributor to the demographic burden is

Increased old age dependency ratio. ***Increased old age dependency ratio*** - An **increased old-age dependency ratio** indicates a larger proportion of older, non-working individuals relative to the working-age population. - This demographic shift places a significant **economic and social burden** on the working population and social welfare systems due to increased healthcare and pension costs. *Decreased old age dependency ratio* - A **decreased old-age dependency ratio** would imply a smaller proportion of elderly dependents, which would actually reduce the demographic burden, making it an unlikely correct answer. - This scenario would generally be considered economically favorable as it suggests more working-age individuals supporting fewer retirees. *Decreased young age dependency ratio* - A **decreased young-age dependency ratio** means fewer children are dependent on the working-age population, which generally lessens the demographic burden. - While it has its own long-term implications (e.g., future workforce shortages), in the immediate sense, it does not contribute to an increased demographic burden. *Increased young age dependency ratio* - An **increased young-age dependency ratio** does contribute to a demographic burden, as more children need support from the working-age population. - However, in many developed and transitioning countries, the **old-age dependency ratio** is emerging as the major or growing contributor to the overall demographic burden due to increasing life expectancy and declining birth rates.

Q: Blood spill in the operation theater is cleaned with _____?

Chlorine compound. ***Chlorine compound*** - **Chlorine-releasing agents** like 1% sodium hypochlorite (bleach) are highly effective against a broad spectrum of microorganisms, including **blood-borne pathogens** such as HIV and Hepatitis B. - Their rapid action and strong oxidizing properties make them the preferred choice for disinfecting surfaces contaminated with blood spills in healthcare settings, ensuring efficient **decontamination**. *Phenolic compounds* - Phenolic compounds are generally used for cleaning and disinfecting **hard, non-porous surfaces** but are less preferred for blood spills due to their slower action and potential for leaving residues. - They are effective against some bacteria and fungi but may not be as rapidly virucidal as chlorine compounds, especially against enveloped viruses in organic matter. *Quaternary ammonium compounds* - **Quaternary ammonium compounds** (Quats) are good general disinfectants for routine cleaning and disinfection of environmental surfaces but have a **lower efficacy against non-enveloped viruses** and spores. - They tend to be inactivated by organic matter, making them less suitable for effective decontamination of **blood spills with high protein content**. *Alcoholic compounds* - **Alcoholic compounds** (e.g., 70% ethanol or isopropanol) are effective disinfectants but are often limited to **small surface areas** or for antiseptic use on skin. - They evaporate quickly and are not ideal for cleaning large blood spills as they may not provide sufficient contact time for effective sterilization in the presence of organic material.
