NEET-PG 2024 Practice Questions

Q: Calculate the maternal mortality ratio (MMR) for the year 2023, given the following data: - Total live births: 4,000 - Women who died: 6 (1 due to a road traffic accident (RTA), 1 due to sepsis, 1 due to obstructed labor, 1 due to eclampsia, 1 due to ectopic pregnancy, and 1 due to a snake bite)

100 per 100,000 live births. ***Correct: 100 per 100,000 live births*** - The **maternal mortality ratio (MMR)** includes deaths directly or indirectly due to pregnancy, childbirth, or within 42 days of termination of pregnancy, **excluding accidental or incidental causes**. - In this scenario, **4 maternal deaths** are identified: sepsis (direct), obstructed labor (direct), eclampsia (direct), and ectopic pregnancy (direct). - **Excluded deaths**: RTA and snake bite are **incidental/accidental deaths** not related to pregnancy complications. - **Calculation**: MMR = (4 / 4,000) × 100,000 = **100 per 100,000 live births** *Incorrect: 75 per 100,000 live births* - This would incorrectly count only **3 maternal deaths** instead of 4, suggesting underestimation or exclusion of a valid maternal death (e.g., ectopic pregnancy). - Represents a **miscalculation** that underestimates maternal mortality burden. *Incorrect: 150 per 100,000 live births* - This would incorrectly include **6 deaths** (all deaths including RTA and snake bite), failing to exclude incidental causes. - Including **non-maternal accidental deaths** inflates MMR and misrepresents actual maternal health outcomes. *Incorrect: 125 per 100,000 live births* - This would incorrectly count **5 deaths**, suggesting inclusion of one incidental death (either RTA or snake bite). - Fails to properly identify and exclude **both incidental deaths**, leading to an overestimated ratio.

Q: Identify the character shown in the image:

Sapna from Leprosy campaign. ***Sapna from Leprosy campaign*** - The image depicts Sapna, a character created for the **National Leprosy Eradication Programme (NLEP)** in India. - This character was developed as part of public health campaigns to spread awareness about leprosy and reduce stigma associated with the disease. - Sapna has been widely used in educational materials and community outreach programs for leprosy awareness. *Arohi from HIV* - Arohi is a different character associated with awareness campaigns for **HIV/AIDS**, not leprosy. - She is part of distinct public health initiatives focusing on HIV prevention, treatment, and stigma reduction under the National AIDS Control Programme. *Meena from UNICEF* - Meena is a prominent animated character created by **UNICEF** to advocate for children's rights, particularly girls' education, gender equality, health, and child protection. - While UNICEF works on a wide range of health issues including communicable diseases, Meena is not specifically associated with the leprosy awareness campaign. *None of the options* - The image clearly depicts the character **Sapna**, who is specifically associated with leprosy awareness campaigns in India. - Therefore, the first option accurately identifies the character and her associated health program.

Q: Which of the following vaccines should be stored at the lowest level in an Ice-Lined Refrigerator (ILR)?

OPV. ***OPV (Oral Polio Vaccine)*** - **OPV** is a **heat-sensitive** vaccine that requires storage at the **coldest temperature** to maintain its potency. - In the traditional ILR storage protocol, OPV is stored at the **lowest level** (bottom shelf) where the temperature is coldest (0-2°C). - This positioning helps prevent heat degradation of the live attenuated virus. - **Note:** OPV has been largely replaced by IPV in India's routine immunization, but this remains a standard exam concept. *DPT (Diphtheria, Pertussis, Tetanus)* - DPT is a **freeze-sensitive vaccine** that should NOT be stored at the coldest parts of the refrigerator. - Freezing can cause **flocculation** and loss of potency, particularly affecting the pertussis component. - Stored in the **middle shelves** to avoid both freezing and excessive heat. *Hepatitis B* - Hepatitis B vaccine is **highly freeze-sensitive** and can lose efficacy permanently if frozen. - The aluminum adjuvant aggregates when frozen, reducing immunogenicity. - Stored in the **middle or upper shelves**, away from the coldest zone. *Rotavirus Vaccine* - Rotavirus vaccine is **freeze-sensitive** and must be protected from sub-zero temperatures. - Freezing can damage the viral particles and reduce vaccine effectiveness. - Stored in the **middle or upper shelves** of the ILR. **Key Principle:** In ILR storage, heat-sensitive vaccines (OPV, measles) go at the bottom (coldest), while freeze-sensitive vaccines (DPT, Hep B, IPV, Rota) go in the middle/upper shelves to prevent freezing damage.

Q: What is the correct chronological order in the disaster management cycle?

Mitigation → Impact → Response → Rehabilitation. ***Mitigation → Impact → Response → Rehabilitation*** - Among the given options, this represents the most **logical chronological sequence** in disaster management - **Mitigation** (risk reduction) occurs before a disaster as preventive measures - **Impact** represents the disaster event occurrence (though technically not a "management phase" but the event itself) - **Response** involves immediate emergency actions during and after the disaster - **Rehabilitation** encompasses recovery and long-term rebuilding efforts - **Note:** The standard disaster management cycle typically includes Mitigation → Preparedness → Response → Recovery, but this option best represents the temporal flow among the choices provided *Impact → Response → Rehabilitation → Mitigation* - Incorrectly places **Impact** first, ignoring that **mitigation** activities occur before disasters as preventive measures - Places **Mitigation** at the end rather than as an ongoing proactive process *Response → Rehabilitation → Mitigation → Impact* - Illogical sequence starting with **Response** before any disaster has occurred - Places **Impact** at the end, which contradicts the temporal nature of disaster occurrence - Fails to recognize mitigation as a preventive stage *Rehabilitation → Mitigation → Response → Impact* - Completely inverted sequence starting with **Rehabilitation** before a disaster has occurred - Does not follow the natural chronological progression of disaster events and management activities - Positions response and impact in an illogical order

Q: In a basic Health Education model, the first step is Awareness, and the second step is Motivation. What is the third step?

Action. ***Action*** - Following **awareness** and **motivation**, **action** is the crucial third step where individuals actively engage in the new behaviors or lifestyle changes. - This step involves the practical implementation of learned health information and the commitment to maintaining these changes over time. *Reflection* - **Reflection** typically occurs after an action has been taken, allowing individuals to review their experiences and learn from them. - It is not the immediate next step after motivation in the sequence of most health education models. *Dedication* - **Dedication** is a quality or characteristic often developed over time as an individual commits to a new behavior, rather than a distinct sequential step in health education models. - While important for sustaining change, it doesn't represent the primary third step in the progression from awareness to behavior change. *Contemplation* - **Contemplation** often precedes motivation, representing the stage where an individual is considering making a change but has not yet committed to it. - In models like the **Transtheoretical Model**, contemplation is an earlier stage than the actual "action" of behavior change.

Q: In Ayushman Bharat under School Health Services, which of the following is not included?

Providing free spectacles. ***Providing free spectacles*** - Under Ayushman Bharat School Health Services and RBSK (Rashtriya Bal Swasthya Karyakram), while **vision screening** is universally implemented, the provision of **free spectacles** is not uniformly guaranteed across all states and depends on fund availability and state-level implementation. - The primary focus remains on **screening and referral**, with spectacle provision being supplementary rather than a core mandated service compared to the other interventions listed. - Unlike the other three services which are universally delivered, free spectacles provision shows **geographic and implementation variability**. *Health check-up/screening* - **Comprehensive health check-ups** and screenings are a mandatory core component of the Ayushman Bharat School Health Program implemented uniformly across all states. - This includes screening for common conditions like **vision problems**, **hearing impairments**, **dental issues**, and growth monitoring. *Albendazole provision* - The administration of **Albendazole** for biannual deworming is a standard, universally implemented practice under the National Deworming Day initiative integrated with School Health Programs. - This is part of a broader strategy to improve the **nutritional status** and overall health of school-going children. *Monthly Iron Folic Acid Supplementation* - **Iron Folic Acid (IFA) supplementation** through the Weekly Iron Folic Acid Supplementation (WIFS) program is a key mandated intervention to combat **anemia** among adolescents (10-19 years). - This is universally implemented through School Health Services and directly contributes to improving **cognitive function** and physical health of students.

Q: A man presented with bilateral non-inflammatory edema after consuming a particular oil. Which test should be performed by the drug inspector to check for the adulterant?

Nitric acid test. ***Nitric acid test*** - The **nitric acid test** is used to detect the presence of **argemone oil** in mustard oil, which is a common adulterant. - **Argemone oil** ingestion can cause **epidemic dropsy**, characterized by bilateral non-inflammatory edema. *Paper chromatography test* - **Paper chromatography** is a technique used for separating and identifying components of a mixture based on differences in their partition coefficient between a stationary and a mobile phase. - While it can identify various substances, it is not the primary or most rapid test specifically for **argemone oil adulteration** when epidemic dropsy is suspected. *Methylene Blue Reduction Test* - The **Methylene Blue Reduction Test** (MBRT) is primarily used in **dairy products** to assess the microbiological quality of milk. - It measures the time taken for methylene blue to decolorize, indicating the number of viable microorganisms, and is not relevant for detecting oil adulterants. *Baudouin test* - The **Baudouin test** is used to detect the presence of **sesame oil** in other oils. - While an important test for adulteration, it is not specific for **argemone oil**, which causes the symptoms described.

Q: The incubation period of a disease is 5-14 days. What should be the quarantine period?

14 days. ***14 days*** - The **quarantine period** should be equal to or slightly longer than the **maximum incubation period** of the disease. - In this case, 14 days covers the entire potential incubation range of 5-14 days, ensuring any exposed individual would develop symptoms within this period if infected. *5 days* - A 5-day quarantine period is too short as it is equal to the **minimum incubation period** and would not capture individuals with longer incubation times. - An individual could become symptomatic and transmit the disease after the 5-day quarantine if their incubation period was longer. *10 days* - A 10-day quarantine period is insufficient as it falls short of the **maximum incubation period** of 14 days. - An individual could still develop symptoms and become infectious up to 4 days after completing a 10-day quarantine. *20 days* - A 20-day quarantine period is unnecessarily long as it exceeds the **maximum incubation period**. - While it ensures coverage of the incubation period, it imposes excessive burden and resource utilization without added public health benefit.

Q: What is the period called between the entry of an organism into the host and the point of maximum infectivity?

Latent Period. ***Latent Period*** - The **latent period** is the time from entry of an organism into the host until the host becomes **infectious** (able to transmit the disease to others). - During this phase, the organism replicates within the host, but the host is not yet shedding sufficient pathogen to transmit infection. - This period ends when the host begins to shed the pathogen and can transmit it to susceptible individuals, which often coincides with peak infectivity in many diseases. - The latent period is crucial in epidemiology for understanding disease transmission dynamics and implementing control measures. *Generation Time* - **Generation time** (or serial interval) in epidemiology refers to the time interval between the onset of infection in a primary case and the onset of infection in a secondary case. - It reflects the average time between successive generations in a chain of transmission. - This is distinct from the latent period and does not specifically address the period until infectivity begins. *Incubation Period* - The **incubation period** is the time between exposure to an infectious agent and the **onset of clinical symptoms**. - It may overlap with or differ from the latent period; some diseases are infectious before symptoms appear (e.g., measles, chickenpox), while others become infectious only after symptoms develop. - The incubation period does not directly correlate with the timing of infectivity. *Prodromal Period* - The **prodromal period** occurs after the incubation period and is characterized by the appearance of **early, nonspecific symptoms** (e.g., malaise, fever, fatigue). - These symptoms precede the characteristic manifestations of the disease. - During the prodromal period, the person may already be infectious, but this period is defined by symptom characteristics, not infectivity timing.

Q: A 27-year-old patient presents with motheaten alopecia, moist perianal lesions, and an asymptomatic macular rash. What is the most likely causative organism?

Treponema. ***Treponema*** - The constellation of **motheaten alopecia**, **moist perianal lesions** (condyloma lata), and an **asymptomatic macular rash** is highly characteristic of **secondary syphilis**, caused by *Treponema pallidum*. - **Condyloma lata** are highly infectious, raised plaques found in moist areas, and the rash can affect palms and soles. *Haemophilus* - *Haemophilus influenzae* is primarily associated with **respiratory infections** (e.g., otitis media, epiglottitis, pneumonia) and sometimes meningitis. - It does not cause the specific dermatological manifestations described in the patient. *Klebsiella* - *Klebsiella pneumoniae* is a common cause of **nosocomial infections**, particularly **pneumonia** (often with currant jelly sputum), **UTIs**, and wound infections. - It is not associated with skin conditions like alopecia or maculopapular rashes typical of syphilis. *Herpes Simplex* - Herpes Simplex Virus (HSV) causes **vesicular or ulcerative lesions**, commonly known as cold sores or genital herpes. - It does not cause motheaten alopecia, moist perianal plaques (condyloma lata), or an asymptomatic macular rash in the same manner as syphilis.
