NEET-PG 2013 Practice Questions

Q: Submandibular nodes are classified as

Level 1B neck nodes. ***Level 1B neck nodes*** - The **submandibular nodes** are located anterior to the posterior belly of the digastric muscle and lateral to the anterior belly of the digastric muscle, placing them within **Level 1B** of the neck lymph node classification [1]. - This level primarily drains the oral cavity, face, and submandibular gland [1]. *Level III neck nodes* - **Level III** nodes are the middle jugular nodes, located between the level of the hyoid bone and the cricoid cartilage. - These nodes are typically found along the **internal jugular vein** and drain structures such as the larynx, hypopharynx, and thyroid. *Level II neck nodes* - **Level II** nodes, or upper jugular nodes, are located from the skull base to the inferior border of the hyoid bone, along the internal jugular vein. - This level is further divided into Level IIA (anterior to the spinal accessory nerve) and Level IIB (posterior to the spinal accessory nerve) and drains structures like the nasopharynx, oropharynx, and parotid gland. *Level 1 A neck nodes* - **Level 1A** nodes refer to the **submental nodes**, which are located between the anterior bellies of the digastric muscles [1]. - These nodes primarily drain the central lower lip, floor of the mouth, anterior tongue, and chin [1].

Q: Descending order of cancer prevalence in males in India?

Lung > oral > pharynx > esophagus. ***Lung > oral > pharynx > esophagus*** - This order represents the **most common cancer prevalence pattern** in Indian males according to **ICMR-NCDIR** population-based cancer registries. - **Lung cancer** ranks highest nationally, strongly associated with **smoking** (bidi and cigarette use). - **Oral cavity cancer** is extremely prevalent in India due to **tobacco chewing, betel quid, and gutka consumption**. - **Pharyngeal cancer** and **esophageal cancer** follow, also linked to tobacco and alcohol use. - Regional variations exist, but this order reflects **national-level data** for Indian males. *Oral > lung > pharynx > esophagus* - While **oral cancer prevalence is very high** in India (competing with lung cancer in some regions), at the **national aggregate level**, lung cancer typically ranks first. - This order may be accurate for **specific regions** with high tobacco chewing prevalence but does not represent the overall national pattern. *Pharynx > lung > oral > esophagus* - **Pharyngeal cancer** is less prevalent than both **lung and oral cancers** in Indian males. - This sequence incorrectly places pharyngeal cancer at the top, which contradicts **Indian cancer registry data**. *Esophagus > oral > stomach > lung* - This order is incorrect as **esophageal and stomach cancers** are significantly less prevalent than **lung and oral cancers** in Indian males. - **Lung cancer consistently ranks at or near the top** in Indian male cancer statistics, making this order epidemiologically inaccurate.

Q: The most important sandfly-transmitted disease in India is-

Kala azar. ***Kala azar*** - **Kala azar**, or **visceral leishmaniasis**, is a severe parasitic disease endemic to India, transmitted primarily by *Phlebotomus argentipes* sandflies. - It is characterized by fever, **splenomegaly**, hepatomegaly, and can be fatal if untreated, making it a major public health concern. *Typhus* - **Typhus** is caused by Rickettsial bacteria and is typically transmitted by lice or fleas, not sandflies. - Symptoms include fever, rash, and headache, differing significantly from the visceral symptoms of Kala azar. *Relapsing fever* - **Relapsing fever** is caused by *Borrelia* bacteria and is transmitted by ticks or lice, not sandflies. - It is characterized by recurring episodes of fever, distinct from the progressive symptoms of Kala azar. *Plague* - **Plague** is caused by *Yersinia pestis* and is primarily transmitted by **fleas** carried by rodents. - It presents with buboes, fever, and sepsis, which are different from the clinical manifestations of sandfly-borne diseases.

Q: In tuberculosis, a 'case' is

Sputum positive. ***Sputum positive*** - In the context of **tuberculosis (TB)**, a 'case' is defined by **bacteriological confirmation**, most commonly through **sputum smear positivity** for acid-fast bacilli (AFB). - According to **RNTCP (Revised National Tuberculosis Control Programme)** guidelines, a sputum smear-positive case is one with at least **two sputum specimens positive for AFB**, or one sputum specimen positive for AFB plus radiographic abnormalities consistent with active pulmonary TB. - A positive sputum smear confirms the presence of **Mycobacterium tuberculosis** in the respiratory tract, indicating active, transmissible infection requiring immediate treatment. *Cough* - **Cough** is a common symptom of tuberculosis but is not sufficient on its own to define a 'case'. - Many respiratory conditions can cause a cough, and it does not confirm the presence of **Mycobacterium tuberculosis** or infectiousness. - Cough lasting more than 2-3 weeks is a screening criterion for TB suspects, not a case definition. *X-ray positive* - A **positive chest X-ray** can show abnormalities consistent with tuberculosis, such as infiltrates, cavities, or hilar lymphadenopathy. - However, radiological findings alone do not definitively confirm a TB diagnosis, as many other conditions can mimic TB on chest X-ray. - Chest X-ray is used for **clinically diagnosed TB cases** when bacteriological confirmation is not possible, but it does not establish active infectivity without microbiological confirmation. *Mantoux positive* - A **positive Mantoux test** (tuberculin skin test) indicates exposure to Mycobacterium tuberculosis and the presence of a cell-mediated immune response. - It signifies **latent TB infection (LTBI)** but does not indicate active, infectious disease. - Many people with positive Mantoux tests never develop active TB and are not considered 'cases'.

Q: A doctor conducts criminal abortion for a woman with consent. He will be prosecuted under which of the following IPC sections?

312 IPC. ***312 IPC*** - This section of the **Indian Penal Code (IPC)** specifically deals with **causing miscarriage** or criminal abortion. - Doing so with the woman's consent, but outside of legal provisions, falls under this section. *316 IPC* - This section deals with **causing the death of a quick unborn child**, an act amounting to culpable homicide. - It would apply if the act intended to cause the death of the child, not just to induce an abortion. *313 IPC* - This section addresses **causing miscarriage without the woman's consent**. - Since the question states the abortion was done "with consent," this section is not applicable. *317 IPC* - This section pertains to the **exposure and abandonment of a child** under twelve years of age by parent or person having care of it. - This is unrelated to the act of performing an abortion.

Q: Telephonophobia refers to -

Beating on ears. ⚠️ **CRITICAL NOTE**: This question contains a terminology error. "Telephonophobia" in medical literature refers to **fear of telephones** (a specific phobia), NOT a physical symptom involving the ears. However, based on the context of this being a NEET-2013 question with "beating on ears" as the answer, this may be: 1. A mistranslation or historical term no longer in use 2. Confusion with another medical term 3. An error in the original examination **For exam purposes, the marked answer reflects the original question**, but students should note: ***Beating on ears*** (Marked as correct per original question) - This answer suggests the question may have intended to ask about a different term or concept - In modern medical terminology, this is **NOT** the definition of telephonophobia - **Telephonophobia** = irrational fear of making or receiving telephone calls (psychiatric condition) *Beating on soles* - This refers to **bastinado**, a form of corporal punishment - Not related to any phobia terminology *Beating on palms* - A form of corporal punishment - Not a recognized medical terminology for any phobia *Pulling of hair* - This describes **trichotillomania**, a body-focused repetitive behavior - Trichotillomania involves recurrent, irresistible urges to pull out hair from the scalp, eyebrows, or other areas **Recommendation**: This question should be reviewed for medical accuracy. The term "telephonophobia" as used here does not align with standard medical terminology.

Q: Schedule-3 of MCI includes –

Diploma of CPS. ***Diploma of CPS*** - Schedule-3 of the Indian Medical Council Act primarily lists **recognized medical qualifications granted by institutions outside India**, as well as certain specialized diplomas like the **Diploma of College of Physicians and Surgeons (CPS)**. - The inclusion of the Diploma of CPS in Schedule-3 allows its holders to be registered as medical practitioners in India for specific purposes. *DNB degree* - The **Diplomate of National Board (DNB)** is a postgraduate medical qualification awarded by the National Board of Examinations (NBE) in India. - DNB degrees are typically listed under **Schedule-1** or **Schedule-2** of the Indian Medical Council Act, not Schedule-3, as they are granted by an Indian authority. *MBBS degree of Indian universities* - **MBBS degrees awarded by universities in India** are recognized under **Schedule-1** of the Indian Medical Council Act. - Schedule-1 specifically lists all medical qualifications granted by universities or medical institutions in India. *MBBS degree of foreign universities* - While MBBS degrees from foreign universities are recognized, their recognition is usually governed by **Schedule-2** of the Indian Medical Council Act, which lists medical qualifications granted by institutions outside India and recognized by the Indian Medical Council after fulfilling certain conditions. - Schedule-3 primarily includes a different set of foreign or specialized qualifications, not the general MBBS degree from foreign universities.

Q: Rash is absent in ?

Q. fever. ***Q. fever*** - Q fever, caused by **Coxiella burnetii**, is characterized by **flu-like symptoms**, pneumonia, and hepatitis, but **does not typically present with a rash**. - This differentiates it from other rickettsial infections that commonly involve skin manifestations. *Endemic typhus* - Endemic (murine) typhus, caused by **Rickettsia typhi**, is transmitted by **fleas** and commonly presents with a **maculopapular rash** on the trunk and extremities [2]. - The rash usually appears several days after fever onset [2]. *Epidemic typhus* - Epidemic typhus, caused by **Rickettsia prowazekii** and transmitted by the **human body louse**, classically presents with a **centrifugal rash** that spares the face, palms, and soles [2]. - The rash typically starts on the trunk and spreads outwards [2]. *Scrub typhus* - Scrub typhus, caused by **Orientia tsutsugamushi**, is transmitted by **chiggers** and often features an **eschar** (a necrotic lesion at the bite site) along with a **maculopapular rash** [1]. - The rash may be transient or absent in some cases, but an eschar is a highly characteristic finding [1].

Q: Inactivated SA 14-14-2 vaccine is an example of which type of vaccine?

Live attenuated vaccine. ***Live attenuated vaccine*** - The **SA 14-14-2 vaccine** is a **live attenuated Japanese Encephalitis (JE) vaccine** developed through serial passage and attenuation of the wild-type SA 14 strain. - The designation "14-14-2" refers to the specific **attenuated strain** after multiple passages, not to an inactivation process. - This vaccine uses **weakened (attenuated) virus** that can replicate minimally, providing robust and long-lasting immunity similar to natural infection. - It is widely used in **China, India, and other Asian countries** in national immunization programs. *Inactivated vaccine* - While there is also an **inactivated version** of the SA 14-14-2 strain (vero cell-derived inactivated JE vaccine), the term "SA 14-14-2 vaccine" by itself typically refers to the **live attenuated formulation**. - Inactivated vaccines contain killed viral particles that cannot replicate. *Toxoid vaccine* - **Toxoid vaccines** are based on inactivated bacterial toxins (toxoids), not viral antigens. - Examples include vaccines for **tetanus** and **diphtheria**, which target toxins produced by bacteria. - This type does not apply to viral vaccines like Japanese Encephalitis. *Subunit vaccine* - **Subunit vaccines** contain only specific purified antigenic components (proteins, polysaccharides) rather than whole organisms. - Examples include **Hepatitis B vaccine** (HBsAg) and **HPV vaccine**. - The SA 14-14-2 vaccine uses the whole attenuated virus, not subunits.

Q: The difference between contamination and infection is that in infection

Infectious agent is in the body of human. ***Infectious agent is in the body of human*** - **Infection** implies that microorganisms have successfully **invaded the host tissues** and are replicating within the body, potentially causing a host response or disease. - The presence of the pathogen *inside* the body, beyond just surface adherence, is the defining characteristic of infection. *Arthropods on the body surface* - This describes an **infestation** (e.g., lice, mites), where the arthropods are physically present on the body surface but may not have *invaded* tissues in the same way bacteria or viruses do during an infection. - While some arthropods can transmit infectious agents, their mere presence on the surface is not synonymous with an internal infection. *Infectious agent is on body surface or on non-human objects* - This scenario describes **contamination**, where microorganisms are present on surfaces (either human skin or inanimate objects) but have not yet penetrated or established themselves within host tissues. - Contamination is a potential precursor to infection but is not an infection itself. *Infectious agents on clothes* - This is a clear example of **fomite contamination**, where infectious agents are present on inanimate objects like clothing. - The microorganisms are external to the body and are not causing an infection in the person wearing the clothes unless they are transferred and subsequently invade the host.
