NEET-PG 2013 Practice Questions

Q: Which color indicates the highest priority in triage?

Red. ***Correct: Red*** - The color **red** is universally used in triage systems to designate the **highest priority** patients, indicating immediate threats to life or limb. - Patients triaged as red require **immediate intervention** and transport to maximize their chances of survival. *Incorrect: Yellow* - **Yellow** indicates a **delayed priority**, meaning patients have serious injuries but their conditions are not immediately life-threatening. - These patients can typically wait for a few hours before receiving definitive medical care. *Incorrect: Green* - **Green** is assigned to patients with **minor injuries** or illnesses that are unlikely to deteriorate over time. - They are considered walking wounded and can often wait for an extended period or be treated with minimal resources. *Incorrect: Black* - **Black** signifies **deceased** or expectant patients, indicating those whose injuries are so severe that survival is unlikely given the available resources. - Resources are typically withheld from these patients to prioritize those with a higher chance of survival.

Q: In psychiatric assessment, which term refers to a temporary and subjective judgment or viewpoint expressed by a patient regarding their condition or treatment?

Opinion. ***Opinion*** - An **opinion** is a transient, personal judgment or viewpoint that a patient expresses, often based on their current understanding or feelings. - It does not necessarily reflect deep-seated convictions but rather a momentary take on their condition or treatment. *Belief* - A **belief** is a more deeply held and enduring conviction that a patient holds, often influencing their perspective and decision-making over time. - Unlike an opinion, a belief is less likely to change quickly and can be foundational to a patient's understanding of their health or illness. *Practice* - **Practice** refers to the regular implementation of specific behaviors, routines, or strategies, especially those related to treatment or self-care. - It describes actions rather than a patient's thoughts, judgments, or viewpoints. *Attitude* - An **attitude** is a more stable predisposition or mental stance towards an object, person, or situation, encompassing thoughts, feelings, and behavioral intentions. - While it can influence opinions, an attitude is a broader and more consistent concept than a temporary judgment.

Q: In the ESI programme, employers and employees in the organized sector contribute to the fund. What is the employer's contribution?

4.75%. ***4.75%*** - The **Employees' State Insurance (ESI) program** is an integrated social security scheme designed to protect workers in the organized sector. - As of 2019, the employer's contribution rate to the ESI fund is set at **4.75%** of the employee's gross wages, while the employee contributes 0.75%. *3.25%* - This percentage is **not the current employer contribution rate** for the ESI scheme; it is higher than the employee's contribution but less than the actual employer's share. - Prior to 2019, the employer's contribution was 4.75% and the employee's contribution was 1.75%, which sums up to 6.5%. The figures were revised on 13.06.2019 reducing the overall contribution from 6.5% to 4%. *2.75%* - This is not the current contribution rate for either the employer or the employee under the ESI program; it falls outside the established percentages. - The ESI scheme ensures compliance through fixed statutory contributions from both parties, which are not represented by this figure. *1.75%* - This was the **employee's contribution rate** to the ESI fund prior to the 2019 revision, not the employer's. - The current employee contribution rate is significantly lower at 0.75%.

Q: What is the common threshold for statistical significance in hypothesis testing?

0.05. ***Correct: 0.05*** - A **p-value of 0.05 (or 5%)** is the most widely accepted and **conventional threshold** for statistical significance in most scientific fields, including medicine - This represents a **5% probability** of observing the results if the **null hypothesis** were true (Type I error or α level) - This is the **standard alpha level** taught in biostatistics and most commonly used in medical research *Incorrect: 0.01* - While 0.01 indicates **higher statistical confidence** (1% chance of Type I error), it is more stringent than the standard threshold - Used in studies requiring **greater certainty** or where false positives have severe consequences - Not the most common or default threshold in general hypothesis testing *Incorrect: 0.02* - A p-value of 0.02 represents a **2% chance of Type I error** - While statistically valid, it is **not a conventional alpha level** for most hypothesis tests - Not the standard threshold taught or applied in medical statistics *Incorrect: 0.03* - A p-value of 0.03 represents a **3% chance of Type I error** - This is **not a standard choice** for statistical significance testing - Not the conventionally prescribed alpha level in biostatistics

Q: What is the schedule of intradermal rabies vaccine?

2-0-2-0-1-1. ***2-0-2-0-1-1*** - This schedule represents the **Thai Red Cross (TRC) regimen** for intradermal rabies vaccination that was standard at the time of this exam (2013). - The numbers indicate the number of vaccine doses administered at different sites: **2 doses on day 0** (bilateral deltoids), **0 doses on day 3**, **2 doses on day 7** (bilateral deltoids), **0 doses on day 14**, **1 dose on day 28**, and **1 dose on day 90**. - This was the **answer expected for NEET 2013** based on the guidelines prevalent at that time. - **Note:** Current WHO guidelines (post-2013) recommend the updated 2-2-2-0-1-1 schedule (4-site ID regimen) which includes doses on days 0, 3, 7, and 28. *2-2-0-1-0-1* - This schedule is **not a recognized** intradermal rabies vaccination protocol. - Does not match any standard WHO-approved regimen for intradermal administration. *2-2-2-0-1-1* - While this may appear incorrect for the 2013 exam context, this schedule actually represents the **current updated Thai Red Cross (4-site ID) regimen** recommended by WHO in recent guidelines. - This regimen provides doses on **days 0, 3, 7, 28, and 90**, which is now the preferred intradermal schedule. - However, for the NEET 2013 exam, the older 2-0-2-0-1-1 schedule was the expected answer. *8-4-4-1-0-1* - This schedule is **not a standard regimen** and involves an impractically high number of doses. - No recognized intradermal rabies protocol uses this many doses on initial days. - Would be **unnecessary and impractical** for effective post-exposure prophylaxis.

Q: Spot map is used for?

Local distribution of disease. ***Local distribution of disease*** - A **spot map** visually represents the geographic distribution of individual cases of a disease or health event. - Each 'spot' on the map corresponds to the exact location where a case occurred, making it ideal for identifying **clusters** or patterns of disease within a specific area. *Rural-urban variation* - While a spot map could potentially show cases in both rural and urban settings, its primary purpose is not to specifically highlight the differences between these two broad categories. - Other types of **thematic maps** or **statistical analyses** are better suited for assessing rural-urban variations. *National variation* - A spot map would be impractical for showing national variation in detail, as it would require plotting individual cases across an entire country, leading to an overly cluttered and uninterpretable image. - **Choropleth maps**, which use shading or colors to represent data for predefined geographic areas (like states or provinces), are more appropriate for illustrating national trends or variations. *None of the options* - This option is incorrect because the primary use of a spot map aligns directly with illustrating the **local distribution of disease**.

Q: Which field of study focuses on person-to-person inter-relationships in a society?

Sociology. ***Sociology*** - **Sociology** is the scientific study of **society**, patterns of **social relationships**, social interaction, and culture. - It directly addresses **person-to-person inter-relationships** by examining groups, organizations, and societies, and how individuals interact within these structures. *Economics* - **Economics** primarily deals with the production, distribution, and consumption of goods and services, and the management of **scarce resources**. - While it involves human interaction, its focus is on **market dynamics** and resource allocation rather than social relationships themselves. *Psychology* - **Psychology** is the scientific study of the **mind and behavior**, focusing on individual thought processes, emotions, and individual responses. - It examines human behavior at the **individual level**, rather than the broader societal inter-relationships between people. *Anthropology* - **Anthropology** is the study of **humanity**, especially focusing on human societies and cultures and their development. - While it examines human social structures, its scope is often broader, encompassing **cultural evolution** and diverse societies rather than the specific patterns of inter-relationships within a single society like sociology.

Q: Darting motility which occurs in V.cholerae, also found in -

Campylobacter jejuni. ***Campylobacter jejuni*** - *Campylobacter jejuni* is well-known for its **rapid, corkscrew-like motility**, often described as **darting motility**, which is a key characteristic for its identification. - This characteristic movement is due to its **polar flagella** and helps the bacterium penetrate the intestinal mucosa. *Shigella* - *Shigella* species are notable for being **non-motile**, a crucial feature distinguishing them from other enterobacteriaceae. - Their lack of flagella and motility prevents them from exhibiting darting or any other form of self-propulsion. *Bacillus anthracis* - *Bacillus anthracis* is typically described as **non-motile** in its vegetative form. - While other *Bacillus* species can be motile, *B. anthracis* lacks the flagella necessary for darting motility. *Pneumococcus* - *Pneumococcus* (Streptococcus pneumoniae) is a **non-motile** bacterium. - It does not possess flagella and therefore cannot exhibit darting or any other type of active movement.

Q: Which of the following conditions is NOT caused by Aspergillus?

Dermatophytosis. ***Dermatophytosis*** - This condition is caused by **dermatophytes** (e.g., *Trichophyton*, *Microsporum*, *Epidermophyton*), which are a specific group of fungi that metabolize keratin. - *Aspergillus* species are generally **opportunistic molds** but do not typically cause dermatophytosis, which is a superficial fungal infection of the skin, hair, or nails. *Otomycosis* - **Otomycosis** is a fungal infection of the external ear canal, and *Aspergillus* species are a common cause, particularly *Aspergillus niger*. - It can lead to ear pain, discharge, itching, and hearing impairment. *Allergic sinusitis* - **Allergic fungal sinusitis (AFS)** is a common form of fungal sinusitis where *Aspergillus* species are significant contributors, often leading to a thick, tenacious allergic mucin. - This condition is an IgE-mediated hypersensitivity reaction to the fungal elements in the nasal and sinus cavities. *Bronchopulmonary allergy* - **Allergic bronchopulmonary aspergillosis (ABPA)** is a hypersensitivity reaction to *Aspergillus fumigatus* antigens that colonize the airways, particularly in individuals with asthma or cystic fibrosis. - It results in recurrent episodes of wheezing, cough, and transient pulmonary infiltrates, and can lead to bronchiectasis if left untreated.

Q: Which of the following is an intermediate level disinfectant?

Hypochlorite. ***Hypochlorite*** - **Hypochlorite** (e.g., sodium hypochlorite, bleach) is an effective **intermediate-level disinfectant** commonly used for surface disinfection and water purification. - It works by **oxidizing cellular components** and disrupting membrane function in microorganisms, effective against a wide range of bacteria, viruses, and some fungi. *2% glutaraldehyde* - **2% glutaraldehyde** is a **high-level disinfectant** and **sterilant** often used for heat-sensitive medical equipment like endoscopes. - It is effective against bacterial spores, mycobacteria, fungi, and viruses, which exceeds the scope of intermediate-level disinfection. *Ethylene oxide* - **Ethylene oxide** is a **gaseous sterilant** used for heat-sensitive and moisture-sensitive medical devices, making it a high-level modality. - It works by **alkylating proteins and nucleic acids**, effectively killing all forms of microbial life, including spores. *None of the options* - This option is incorrect because **Hypochlorite** is indeed an intermediate-level disinfectant. - The classification of disinfectants is based on their ability to kill different types of microorganisms, with hypochlorite falling squarely into the intermediate category.
