NEET-PG 2013 - Community Medicine Practice Questions

Q: To achieve neonatal tetanus elimination, the incidence of neonatal tetanus per 1000 live births should be reduced to less than:

1.0. ***1.0*** - The international target for **neonatal tetanus elimination (NTE)** as defined by WHO/UNICEF is an incidence rate of **less than 1 case per 1,000 live births per year** in every district of a country. - This is the globally recognized threshold for declaring that neonatal tetanus has been eliminated as a public health problem. - Countries achieving this target at the district level are considered to have achieved NTE. *0.1* - While 0.1 per 1,000 live births represents an extremely low incidence, this is not the WHO-defined threshold for **neonatal tetanus elimination**. - The elimination target is less stringent at <1 per 1,000 live births, making disease control achievable while still representing a major public health success. *0.2* - An incidence of 0.2 per 1,000 live births, though very low, is not the internationally recognized threshold for **neonatal tetanus elimination**. - The established WHO/UNICEF target is <1 per 1,000 live births in every district. *0.5* - An incidence of 0.5 per 1,000 live births indicates excellent control of neonatal tetanus but is not the specific cut-off value. - The WHO criterion for elimination is less than 1 case per 1,000 live births per year at the district level.

Q: Antiserum is available for passive immunization against ?

Rabies. ***Rabies*** - **Antiserum** (or rabies immune globulin, RIG) provides immediate **passive immunity** against rabies, neutralizing the virus before the body can mount an active immune response. - It is administered in conjunction with the **rabies vaccine** for post-exposure prophylaxis, especially in severe exposures. *Typhoid* - **Typhoid fever** is primarily prevented through vaccination (active immunization) and improved sanitation. - There is no routinely available antiserum for **passive immunization** against *Salmonella typhi* infection. *Measles* - **Measles** is prevented through active immunization with the MMR (measles, mumps, rubella) vaccine. - While immune globulin can be used for passive protection in exposed, immunocompromised individuals, it's not commonly referred to as "antiserum" in the same context as rabies. *Mumps* - **Mumps** is prevented by active immunization with the MMR vaccine. - Similar to measles, there is no commonly used specific antiserum for **passive immunity** against mumps in the clinical setting.

Q: What is the appropriate diluent for the BCG vaccine?

Sterile distilled water. ***Sterile distilled water*** - **Sterile distilled water** is the recommended diluent for the **BCG vaccine** to ensure proper reconstitution and antigen stability. - Using the correct diluent is critical for maintaining the **efficacy** and safety of the vaccine. *Sterile normal saline* - **Sterile normal saline** (0.9% NaCl) can be used as a diluent for some vaccines, but it is **not appropriate for BCG** as it can negatively impact vaccine viability. - The **salt concentration** in saline can affect the live attenuated organisms in the BCG vaccine. *Sterile dextrose solution* - **Dextrose solutions** are generally avoided as vaccine diluents due to their potential to support **bacterial growth** or alter vaccine stability. - They are primarily used for **intravenous fluid administration** and not for vaccine reconstitution. *Colloid solutions* - **Colloid solutions** like albumin or dextran are never used as vaccine diluents as they can interfere with the **vaccine antigens** and cause adverse reactions. - These solutions are typically used for **plasma volume expansion** and have no role in vaccine preparation.

Q: Which immunization is typically given at 6 months of age?

DPT vaccine. **DPT vaccine** - The DPT (diphtheria, pertussis, and tetanus) vaccine is administered in multiple doses during infancy as part of the primary immunization series. - At **6 months of age**, the **third dose of DPT** is typically given (following doses at 6 weeks, 10 weeks, and 14 weeks according to the Indian immunization schedule). - Among the options provided, DPT is the only vaccine routinely administered at 6 months of age. - This vaccine protects against three serious bacterial infections: **diphtheria**, which can cause breathing problems; **pertussis (whooping cough)**, a severe respiratory illness; and **tetanus**, which causes painful muscle spasms. *Measles vaccine* - The measles vaccine (given as part of the **MMR vaccine** or as MR vaccine in India) is typically administered at **9 to 12 months of age** for the first dose, and a second dose between 15-18 months or 4-6 years. - It is not routinely given at 6 months, as maternal antibodies can interfere with its effectiveness at this younger age. *BCG vaccine* - The BCG (Bacillus Calmette-Guérin) vaccine protects against **tuberculosis** and is given at **birth** or in early infancy as a single dose. - It is not administered at 6 months of age. *None of the options* - This option is incorrect because the **DPT vaccine** (third dose) is a standard immunization given at 6 months of age according to the Indian immunization schedule. - Multiple vaccines are actually given at 6 months (including OPV, Hepatitis B, Hib, PCV), but among the listed options, only DPT is correct.

Q: Which of the following is the nodal centre for disaster management at the district level in India?

District Collector's office. ***District Collector's office*** - The **District Collector (Deputy Commissioner/District Magistrate)** is the **chairperson of the District Disaster Management Authority (DDMA)** as per the Disaster Management Act, 2005. - The District Collector's office serves as the **nodal centre for all disaster management activities** at the district level, with overall administrative and operational responsibility. - The District Collector coordinates all disaster preparedness, response, relief, and rehabilitation activities in the district. *Emergency Operations Center (EOC)* - The **EOC** is a **functional/operational unit** that assists in disaster coordination and information management. - It serves as a support mechanism for the District Collector but is **not the nodal agency itself**. - The EOC operates under the administrative framework of the District Disaster Management Authority. *PHC* - A **Primary Health Centre (PHC)** is the first point of contact for healthcare in rural areas. - Its role in disasters is limited to providing initial medical aid and supporting community health needs. - It is not an administrative or coordinating body for overall disaster management. *CHC* - A **Community Health Centre (CHC)** provides secondary healthcare services and acts as a referral center for PHCs. - While important for medical response during disasters, it has no administrative role in disaster management coordination.

Q: Which of the following is NOT typically associated with the recovery phase after a disaster?

Response. ***Response (Correct Answer)*** - **Response** activities occur during or immediately after the disaster event, NOT in the recovery phase - Includes immediate search and rescue, medical triage, emergency shelter provision, and acute crisis management - The goal is to **save lives, protect property**, and meet basic human needs during the acute crisis (typically 0-72 hours) - This is distinct from the recovery phase, which begins after the immediate emergency is controlled *Rehabilitation* - **Rehabilitation** is a key component of the **recovery phase** - Focuses on restoring services and infrastructure to acceptable levels after the initial emergency - Includes both physical recovery of individuals and return to functionality of critical systems like utilities and healthcare *Reconstruction* - **Reconstruction** is a major part of the **recovery phase** - Involves rebuilding infrastructure, homes, and communities, often to a better, more resilient standard than before - This is often a lengthy process aiming for long-term stability and development *Mitigation* - While **mitigation** can be incorporated into recovery planning, it is primarily focused on **future disaster prevention** - Measures taken to reduce the **loss of life and property** from future disasters - Can be implemented before a disaster strikes or planned during recovery, but the emphasis is on **risk reduction for future events** rather than immediate restoration from the current event

Q: Which of the following vaccines is not typically given in disaster situations?

Influenza. ***Influenza*** - **Influenza vaccination** is generally **NOT a priority** in acute disaster response and emergency vaccination campaigns. - While influenza can spread in crowded conditions, routine disaster response protocols focus on **immediately life-threatening and epidemic-prone diseases** rather than seasonal respiratory infections. - Influenza vaccination requires **cold chain maintenance** and repeated doses, making it logistically challenging in emergency settings. - WHO and SPHERE guidelines do not list influenza among priority vaccines for disaster situations unless there is a specific ongoing outbreak. *Cholera* - **Oral cholera vaccine (OCV)** is increasingly recommended by WHO for disaster settings with **high cholera risk**, particularly in areas with poor water and sanitation. - Modern OCVs (like Shanchol and Euvichol) have improved **cost-effectiveness** and logistics, making them viable for mass campaigns. - Used in conjunction with **WASH interventions** (water, sanitation, hygiene) for comprehensive cholera control. *Measles* - **Measles vaccination** is the **highest priority** vaccine in disaster response, particularly for children aged 6 months to 15 years. - Its **extreme contagiousness** (R0 = 12-18) and high mortality in malnourished populations make it critical. - WHO recommends measles vaccination within the **first days** of a disaster response in displacement settings. *Tetanus* - **Tetanus toxoid** (often as Td or DT) is essential in disasters involving injuries, floods, earthquakes, or debris. - Protects against **_Clostridium tetani_** infection from contaminated wounds. - Part of standard **wound management protocols** in emergency medical care.

Q: In the context of triage, what color would be assigned to a moribund patient?

Black. ***Black*** - A **black tag** is assigned to patients who are **deceased** or have injuries so severe that survival is unlikely, and resources would be better used on patients with a higher chance of survival. - A **moribund patient** is in a dying state or near death, fitting the criteria for a black tag in triage. *Red* - **Red tags** are for patients with **immediate life-threatening injuries** who have a high probability of survival with prompt intervention. - These patients require immediate medical attention to stabilize fundamental physiological functions. *Yellow* - **Yellow tags** are assigned to patients with **serious injuries** that are not immediately life-threatening. - They require medical attention within a few hours, but their condition is stable enough to wait after red-tagged patients. *Green* - **Green tags** are for patients with **minor injuries** that are non-life-threatening and can wait for medical attention. - These individuals are often referred to as "walking wounded" and can typically care for themselves or assist others.

Q: Which of the following diseases is classified under category-B of bioterrorism?

Cholera. ***Cholera*** - **Cholera** is classified under **Category B** agents due to its moderate ease of dissemination, moderate morbidity rates, and low mortality rates. - While it can cause severe diarrheal disease, its treatment is relatively straightforward with **rehydration therapy**, and it poses a lower risk of mass casualties compared to Category A agents. *Anthrax* - **Anthrax** is a **Category A** bioterrorism agent, characterized by its high mortality rate, ease of dissemination, and potential for major public health impact. - It poses a significant threat due to its ability to form **spores** that are highly resistant and can cause severe lung infection. *Plague* - **Plague** is designated as a **Category A** agent because of its high potential for mass dissemination, high mortality if untreated, and potential to cause widespread panic. - It can be spread via **aerosols** and can lead to severe systemic illness. *Botulism* - **Botulism** is classified as a **Category A** agent due to the extreme potency of the **botulinum toxin**, even in minute quantities, which can cause severe flaccid paralysis and death. - It has a high potential for causing severe public health impact and requires complex medical interventions.
