NEET-PG 2013 Practice Questions

Q: Most basic level of Health Care System in India -

Primary health care. ***Primary health care*** - **Primary health care** is the first point of contact for individuals with the health system, providing essential and accessible healthcare services - In India, it is delivered through **sub-centers** (the most peripheral unit) and **primary health centers (PHCs)**, forming the **most basic and widespread layer** of the healthcare system - This represents the foundational level of care, focusing on preventive, promotive, and basic curative services *Secondary health care* - **Secondary health care** involves more specialized services, typically provided in district hospitals or community health centers (CHCs) - It serves as a referral point from primary care for patients requiring diagnostics, specialist consultations, or inpatient care - This is a **higher level of care** than primary, not the most basic level *Tertiary health care* - **Tertiary health care** offers highly specialized and advanced medical care, often involving complex procedures, specialized investigations, and management of rare or severe diseases - Provided in medical colleges, research institutes, and super-specialty hospitals - This represents the **highest and most advanced level** of the healthcare system, not the most basic *All are same* - This option is incorrect because the Indian healthcare system is structured in a **hierarchical manner** with distinct levels - Each level (primary, secondary, and tertiary) provides different services, varying in complexity, specialization, and accessibility - Primary care is clearly the most basic level, while secondary and tertiary represent progressively higher levels of specialization

Q: Highest level of health care system in India -

Tertiary health care. ***Tertiary health care*** - **Tertiary healthcare** represents the highest level within the healthcare system, offering highly specialized and technologically advanced medical services. - It includes facilities like **super-specialty hospitals** and research centers that provide treatments for complex and rare diseases, often requiring referral from lower levels of care. *Primary health care* - **Primary healthcare** is the first point of contact for individuals, families, and communities with the healthcare system, focusing on prevention, health promotion, and basic curative care. - It is delivered at facilities such as **Sub-centers** and **Primary Health Centers (PHCs)**, addressing common health problems. *Secondary health care* - **Secondary healthcare** provides more specialized medical care than primary care, often involving consultation with specialists and access to basic diagnostic and treatment services. - It is typically delivered at **Community Health Centers (CHCs)** and district hospitals, serving as a referral point from primary care. *All are same* - The different levels of healthcare (primary, secondary, and tertiary) represent a **hierarchical structure** with distinct roles, functions, and levels of specialization. - They are designed to provide a continuum of care, with patients being referred between levels based on their medical needs, ensuring that "all are same" is incorrect.

Q: What is the minimum contact period required for effective chlorination of drinking water?

30 minutes. ***30 minutes*** - A minimum **contact period of 30 minutes** is generally recommended for effective chlorination to sufficiently inactivate most pathogenic microorganisms in drinking water. - This duration allows for adequate time for the **chlorine residual** to penetrate and destroy bacterial and viral structures. *1 hour* - While a longer contact time like 1 hour would be effective, it is not the **minimum required** for practical purposes and might lead to increased operational costs or complexity without significant additional benefit in typical scenarios. - Exceeding the minimum contact time can sometimes lead to the formation of **disinfection byproducts**, although this is more dependent on chlorine concentration and water composition. *2 hrs* - A contact time of 2 hours significantly exceeds the **minimum effective period** for most disinfection needs. - Such extended contact times are usually only considered in specific situations with highly resistant pathogens or particular water quality challenges, or when using **lower chlorine doses**. *4 hrs* - A 4-hour contact period is far beyond the **standard minimum** for effective chlorination of drinking water. - Such long contact times are typically impractical for municipal water treatment and could potentially increase the risk of forming **undesirable disinfection byproducts** if not carefully managed.

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: Miscarriage due to medical negligence is seen under which IPC?

Sec 304A IPC. ***Sec 304A IPC*** - This section specifically deals with **causing death by negligence** (rash or negligent acts not amounting to culpable homicide). - **Medical negligence causing miscarriage** falls under this section as it involves an unintentional harm due to negligent medical practice. - This is the appropriate section when there is no voluntary intent to cause miscarriage, but harm results from professional negligence. *Sec 312 IPC* - This section deals with **voluntarily causing miscarriage**, requiring intentional/voluntary act. - It applies when a person **intentionally** causes a woman to miscarry (criminal abortion). - Medical **negligence** does not constitute a voluntary act in the legal sense, so Sec 312 does not apply to negligence cases. *Sec 310 IPC* - This section is related to **thuggee**, defining someone who habitually commits robbery or child-stealing by murder. - It has no relevance to medical negligence or miscarriage. *Sec 314 IPC* - This section deals with **death caused by an act done with intent to cause miscarriage**. - It applies when an intentional act to cause miscarriage results in the death of the woman. - This requires criminal intent, not negligence.

Q: What is the penalty for violating the Dowry Prohibition Act?

15000 Rs and 5 years. ***15000 Rs and 5 years*** - The **Dowry Prohibition Act of 1961** (as amended) stipulates that any person giving or taking dowry, or abetting the giving or taking of dowry, shall be punishable with imprisonment for a term which shall **not be less than five years** and with a fine which shall **not be less than fifteen thousand rupees** or the amount of the value of such dowry, whichever is more. - This represents the **minimum prescribed penalty** for offenses under Section 3 of the Act. *30000 Rs and 7 years* - While dowry-related offenses can lead to significant penalties, a flat fine of **30,000 Rs** and an imprisonment of **7 years** is not the standard or minimum penalty outlined in the **Dowry Prohibition Act**. - The minimum fine is **15,000 Rs or the dowry amount, whichever is more**, and the minimum imprisonment is **five years**, not seven. *Life imprisonment* - **Life imprisonment** is typically reserved for very severe crimes, and while dowry-related deaths can lead to such severe penalties under **Section 304B IPC for dowry death**, violating the general provisions of the **Dowry Prohibition Act** itself (giving or taking dowry under Section 3) does not directly carry a penalty of life imprisonment. - This option misrepresents the direct penalty for dowry prohibition violations under the Act. *Imprisonment for 10 years* - Imprisonment for **10 years** is not the prescribed minimum or standard penalty for violating the **Dowry Prohibition Act** under Section 3 for giving or taking dowry. - The **minimum imprisonment is five years**, with potential for longer sentences depending on the specific circumstances and judicial discretion.

Q: Which of the following statements about Penicillium marneffei is incorrect?

Forms black colonies. ***Forms black colonies*** - *Penicillium marneffei* typically forms colonies that are often **reddish-beige** or **pigmented red-diffusible**, not black. - The production of a characteristic **red-to-burgundy pigment** is a key identifying feature of this fungus, especially in culture. *Is a dimorphic fungus* - This statement is correct. *Penicillium marneffei* is a **thermally dimorphic fungus**, meaning it grows as a mould at 25°C (room temperature) and as yeast-like cells at 37°C (body temperature). - This dimorphism is crucial for its pathogenesis and identification. *Amphotericin B is used for treatment* - This statement is correct. **Amphotericin B** is a commonly used antifungal agent for the treatment of severe *Penicillium marneffei* infections, particularly in immunocompromised patients. - It is often followed by a maintenance regimen with an azole antifungal like itraconazole. *Causes severe infections in immunocompromised patients* - This statement is correct. *Penicillium marneffei* is an **opportunistic pathogen** that primarily causes severe, disseminated infections in individuals with compromised immune systems, especially those with HIV/AIDS. - Endemic regions include Southeast Asia, where it is a leading cause of systemic mycosis in HIV-positive patients.

Q: Amoebic liver abscess can be diagnosed by demonstrating-

Trophozoites in the pus. ***Trophozoites in the pus*** - **Amoebic liver abscesses** are caused by the invasive **trophozoite stage** of *Entamoeba histolytica*. - Demonstrating **trophozoites** in the characteristic **'anchovy paste' pus** aspirated from the abscess cavity is diagnostic. *Cysts in the pus* - **Cysts** are the **infective stage** of *Entamoeba histolytica* and are typically found in the **feces**, not in an abscess. - Cysts are responsible for transmission and survival outside the host, but they do not cause invasive disease. *Cysts in the liver* - The disease in the liver is caused by **trophozoites**, which invade the intestinal wall and then spread to the liver. - **Cysts** are never found within the liver parenchyma or abscesses. *Trophozoites in the feces* - While **trophozoites** can be found in the feces during acute amoebic dysentery, their presence alone does not confirm a liver abscess. - Furthermore, **trophozoites** are fragile and often difficult to detect in stool samples, especially once the stool has cooled.

Q: Mechanism of action of tranexamic acid is

Prevents fibrinolysis. ***Correct: Prevents fibrinolysis*** - Tranexamic acid is an **antifibrinolytic agent** that works by inhibiting the activation of plasminogen to plasmin. - By preventing the formation of plasmin, it stabilizes **fibrin clots** and reduces bleeding. *Incorrect: Decrease vascular permeability* - This is primarily the mechanism of action of drugs like antihistamines or corticosteroids, which work on **inflammation** and **allergic reactions**. - Tranexamic acid does not directly target vascular permeability; its primary role is in **hemostasis**. *Incorrect: Smooth muscle contraction* - This describes the action of drugs like **vasoconstrictors** (e.g., epinephrine) or agents that promote uterine contractions (e.g., oxytocin). - Tranexamic acid has no direct effect on **smooth muscle contraction**. *Incorrect: Activates Plasmin formation* - This is the opposite of tranexamic acid's action; drugs that activate plasmin, such as **tissue plasminogen activators (tPAs)**, are used to break down clots. - Tranexamic acid specifically **inhibits plasminogen activation**, thereby preventing plasmin formation.
