NEET-PG 2012 Practice Questions

Q: In a 3 month fetus, characteristic feature seen is:

Nails are visible. ***Nails are visible*** - By the end of the **third month** (approximately 12 weeks), the fingers and toes are fully formed, and the beginnings of fingernails and toenails usually become visible. - This marks a significant developmental milestone in fetal maturation during the first trimester. *Meconium is present in the intestines* - **Meconium** begins to form during the **second trimester**, typically around weeks 12-16, with significant accumulation in the latter part of the second and throughout the third trimester. - While some gut movements occur earlier, the presence of well-formed meconium for defecation happens later in fetal development. *Anus formation begins* - The formation of the anus is part of the development of the **cloaca**, which begins much earlier, around the **4th to 7th gestational weeks**. - By 3 months, the anorectal canal is already well-differentiated, so its formation has already been completed. *Limb buds are present* - **Limb buds** appear very early in embryonic development, around the **end of the 4th week**. [1] - By 3 months, the limbs are already well-developed with distinct fingers and toes, so these structures would have passed the "bud" stage.

Q: Kennedy phenomenon is seen in:

Gunshot injury. ***Gunshot injury*** - The **Kennedy phenomenon** describes the pattern of injury observed when a **bullet passes through a body part**, leaving an **exit wound larger than the entrance wound**. - This occurs because the bullet creates a **temporary cavity** that collapses, and the tissue at the exit point is stretched beyond its elastic limit, resulting in a larger defect. *Burns* - Burns are injuries caused by heat, chemicals, electricity, or radiation, resulting in **tissue destruction** and often characterized by **blistering, charring, and loss of skin integrity**. - While burns can cause tissue damage, the mechanism of injury and the resulting wound characteristics are distinctly different from the **ballistic trauma** described by the Kennedy phenomenon. *Contusion* - A **contusion**, or bruise, is a type of injury caused by **blunt force trauma** that damages small blood vessels under the skin, leading to discoloration without breaking the skin surface. - This injury mechanism involves **crushing of tissues** and local hemorrhage, which is fundamentally different from the passage of a projectile through tissues. *Road traffic accident* - A road traffic accident can result in a wide range of injuries, including **blunt force trauma**, **lacerations**, **fractures**, and **internal organ damage**. - While significant tissue damage can occur, the specific pattern of an **entry and a larger exit wound** resulting from a penetrating projectile is not a defining characteristic of RTA injuries.

Q: Not seen in fingerprints:

Grid pattern. ***Grid pattern*** - **Grid patterns** are not a characteristic ridge pattern found in human fingerprints. Fingerprints are formed by epidermal ridges that follow specific, identifiable patterns. - The primary patterns of fingerprints are **loops, whorls, and arches**, which are used for classification and identification. *Whorl* - A **whorl** is one of the three basic fingerprint patterns, characterized by circular or spiral ridges. - Whorls are a common and identifiable feature used in **dermatoglyphics** for fingerprint analysis. *Loop* - A **loop** is the most common fingerprint pattern, characterized by ridges that enter from one side, curve around, and exit from the same side. - **Loops** are a fundamental pattern recognized in forensic science for fingerprint classification. *Arch* - An **arch** is the simplest fingerprint pattern, characterized by ridges that enter from one side, rise in the middle, and exit from the opposite side without forming loops or deltas. - **Arches** are one of the three primary patterns used to classify fingerprints.

Q: In criminal cases, conduct money is paid by:

No conduct money is given. ***No conduct money is given*** - In most criminal law systems, **witnesses compelled to testify** by the prosecution are generally not entitled to conduct money. - The state bears the cost of investigation and prosecution, and witnesses are expected to cooperate in the interest of justice. - This is in contrast to civil cases where the party calling the witness typically pays conduct money for their attendance. *Court* - The court itself does not typically pay conduct money to witnesses in criminal cases. - While it oversees the legal process, the financial aspects of witness appearance are usually handled by the parties involved or the state. *Judge* - A **judge** does not personally disburse funds for conduct money. - The judge's role is to preside over the trial and ensure due process, not to manage financial transactions related to witnesses. *Opposing party* - The opposing party (typically the defense) also does not pay conduct money to witnesses testifying for the prosecution in a criminal case. - If the defense calls its own witnesses, their appearance costs would be a matter for the defense, but this differs significantly from the concept of conduct money in civil cases.

Q: Victim was strangled with elbow around neck. It is called as:

Mugging. ***Mugging*** - **Mugging** (also called "yoking" or "bar arm strangle") is the forensic medicine term for strangulation using the **arm or elbow encircling the neck**. - In this technique, the assailant typically approaches from behind and applies the forearm or crook of the elbow across the victim's throat, compressing the neck structures. - This method compresses the carotid arteries and jugular veins, leading to rapid unconsciousness and potential death from cerebral hypoxia. *Throttling* - **Throttling** specifically refers to manual strangulation using the **hands (fingers and thumbs)** to compress the neck. - The assailant applies direct pressure with their fingers on the front or sides of the victim's neck. - This differs from the scenario described, which involves the elbow/arm, not the hands. *Burking* - **Burking** is a historical method of murder involving suffocation by covering the mouth and nose while applying pressure to the chest. - Named after William Burke, this method was designed to leave minimal external marks on the body. - It does not involve neck compression or strangulation. *Garrotting* - **Garrotting** is strangulation using a **ligature** (rope, wire, cloth, or cord) tightened around the neck. - This involves an instrument rather than direct body contact. - It differs from mugging, which uses the arm/elbow without any intermediate object.

Q: Oximes are contraindicated in which poisoning:

Carbamate. ***Carbamate*** - Traditionally, oximes were considered **contraindicated** in carbamate poisoning based on concerns they could worsen the **cholinergic crisis** by reactivating carbamylated acetylcholinesterase. - Carbamates spontaneously **decarbamylate** from acetylcholinesterase within minutes to hours, so their inhibition is typically **short-lived and reversible**. - **Clinical relevance**: While modern evidence suggests oximes are more likely **ineffective** rather than harmful in carbamate poisoning, they are generally **not recommended** as they provide no therapeutic benefit. For exam purposes, particularly in historical contexts (NEET 2012-2013), carbamate poisoning is the answer for oxime contraindication. *Diazinon* - Diazinon is an **organophosphate**, and oximes like pralidoxime are **strongly indicated** for reactivating **acetylcholinesterase** inhibited by organophosphates. - Oximes are a crucial part of recommended antidotal therapy alongside **atropine** for severe organophosphate poisoning. - Must be administered early (within 24-48 hours) before **aging** of the phosphorylated enzyme occurs. *Phorate* - Phorate is a highly toxic **organophosphate pesticide**, and oximes are **indicated** for treatment of phorate poisoning. - Oximes work by **dephosphorylating** (nucleophilic attack on) the acetylcholinesterase enzyme, which has been inhibited by the organophosphate, restoring its catalytic function. *Malathion* - Malathion is an **organophosphate insecticide**, and oxime reactivators are **effective** in malathion poisoning. - The mechanism involves **cleaving the phosphate bond** from the serine residue on the acetylcholinesterase enzyme, allowing it to metabolize acetylcholine again and reverse cholinergic toxicity.

Q: Erotomania is seen in:

Delusional disorder. ***Delusional disorder*** - Erotomania (De Clérambault's syndrome) is **classically a subtype of delusional disorder** known as **erotomanic type** in DSM-5. - Characterized by a **non-bizarre delusion** that another person, usually of higher social status, is in love with the individual. - The delusion persists despite clear evidence to the contrary and is the **primary psychiatric diagnosis** for erotomania. - Patients may engage in behaviors like following, attempting contact, or surveillance of the object of their delusion. *Bipolar mania* - While **psychotic features can occur** in severe manic episodes, they typically involve **grandiose delusions** about one's own abilities, power, wealth, or special identity. - Erotomania is **not a characteristic or common psychotic feature** of bipolar mania. - Manic psychosis more commonly presents with mood-congruent grandiose delusions rather than erotomanic delusions. *Obsessive compulsive disorder* - Characterized by **obsessions** (intrusive, unwanted thoughts) and **compulsions** (repetitive behaviors performed to reduce anxiety). - These thoughts are **ego-dystonic** and recognized as excessive or irrational by the patient. - Erotomania is a **fixed delusional belief** without insight, fundamentally different from OCD phenomenology. *Mania without psychotic features* - By definition involves elevated mood, increased energy, and decreased need for sleep **without delusions or hallucinations**. - Erotomania is a **delusional belief**, indicating presence of psychotic features. - This diagnosis would exclude any presentation with erotomanic delusions.

Q: Type of schizophrenia with intellectual disability:

Pfropf schizophrenia. ***Pfropf schizophrenia*** - **Pfropf schizophrenia** is a historical term specifically used to describe a form of schizophrenia that develops in individuals with **pre-existing intellectual disability** (formerly termed mental retardation). - The term "Pfropf" is derived from German, meaning "grafted" or "engrafted," referring to schizophrenia being "grafted onto" pre-existing intellectual disability. - This term distinguishes it from other types of schizophrenia where intellectual disability is not a primary defining characteristic. - While this classification is largely historical (modern DSM-5 has removed schizophrenia subtypes), it remains relevant for older examination questions. *Catatonic schizophrenia* - Characterized primarily by prominent **psychomotor disturbances**, which can include stupor, catalepsy, waxy flexibility, mutism, and negativism. - While intellectual disability might coexist, it is not a defining feature of the catatonic subtype itself. *Paranoid schizophrenia* - Marked by the prominence of **delusions**, typically persecutory or grandiose, and **auditory hallucinations**. - Intellectual disability is not a core diagnostic criterion or a defining characteristic of this subtype. *Hebephrenic schizophrenia* - Also known as **disorganized schizophrenia**, this type is characterized by marked **disorganization of thought processes**, flat or inappropriate affect, and bizarre behavior. - While it often presents early and can lead to significant functional impairment, intellectual disability is not a defining feature; rather, the primary disturbance is in thought and emotion.

Q: Periorbital ecchymosis without direct orbital trauma (raccoon eyes) is most commonly associated with injury to:

Base of skull. ***Base of skull*** - **Periorbital ecchymosis** (raccoon eyes) is a classic sign of a **basilar skull fracture**, particularly one involving the **anterior cranial fossa**. - The fracture allows blood to leak from the cranial cavity and track along fascial planes into the periorbital soft tissues. - The key feature is that ecchymosis occurs **without direct trauma to the orbit or eye**, indicating the primary injury is to the **skull base**. - Often associated with CSF rhinorrhea and requires CT imaging for diagnosis. *Eye* - The question specifically states the ecchymosis occurs "**without direct orbital trauma**," meaning the eye/orbit is NOT the site of injury. - The eye region is where the sign **manifests** (blood tracks to this area), but it is not the site of the underlying injury. - Direct eye trauma would cause immediate localized periorbital swelling, not the delayed bilateral "raccoon eyes" pattern. *Pinna* - Pinna (ear) injury can be associated with head trauma, and Battle's sign (retroauricular ecchymosis) indicates temporal bone fracture. - However, pinna injury does not cause periorbital ecchymosis; these are separate findings. *Scalp* - Scalp injuries cause localized bleeding and swelling at the impact site. - While scalp trauma may accompany basilar skull fracture, the scalp itself is not the source of periorbital ecchymosis. - Blood from scalp wounds tracks superficially, not into deep fascial planes leading to the orbits.
