NEET-PG 2024 Practice Questions

Q: What is the sequence of rigor mortis in the human body?

Head to foot. ***Head to foot*** - Rigor mortis follows **Nysten's Law**, progressing in a **descending pattern** from head to feet. - Begins in smaller muscles with higher metabolic activity: **masseter (jaw), eyelids, and facial muscles** (2-4 hours post-mortem). - Then progresses to **neck → upper extremities → trunk → lower extremities** (completing over 12 hours). - This sequence relates to muscle size, ATP depletion rates, and surface area-to-volume ratios. *Centre to periphery* - This pattern does **not accurately describe** rigor mortis progression. - While smaller muscles are affected first, the progression follows a **craniocaudal (head-to-foot) direction**, not a radial center-to-periphery pattern. - The anatomical distribution is vertically sequential, not centrifugal. *Foot to head* - This is the **opposite of the established progression** described by Nysten's Law. - Lower extremity muscles develop rigor mortis **last**, not first. - This would contradict classic forensic pathology observations. *Simultaneously* - Rigor mortis is a **time-dependent sequential process**, not simultaneous. - Different muscle groups deplete ATP and accumulate calcium at **varying rates over several hours**. - The progressive nature (2-4 hours onset, 12 hours peak, 36-48 hours resolution) demonstrates it cannot be simultaneous.

Q: From a medico-legal perspective, in cases of sexual assault involving a female victim, what type of court proceeding is typically used to record medical evidence and testimony to protect the victim's privacy?

In camera proceedings. ***In camera proceedings*** - **In camera proceedings** (Latin for "in chambers") refer to court hearings conducted in **private**, with the public and media excluded, to protect the victim's privacy and dignity. - Under **Section 327(2) of CrPC**, cases of sexual offences against women must be conducted in camera to prevent further trauma and ensure the victim can provide testimony comfortably. - This legal provision ensures **confidentiality** of victim identity and prevents public disclosure of sensitive medical evidence and testimony. - The proceedings are still officially recorded and form part of the legal record, but occur in a closed, private setting. *Open court proceedings* - **Open court proceedings** allow public and media access, which would severely compromise the victim's privacy and cause additional psychological trauma. - Such public exposure is specifically prohibited in sexual assault cases under Indian law to protect the **victim's identity** and well-being. *Closed court proceedings* - While this term might seem similar, **"closed court"** is not the standard legal terminology used in Indian jurisprudence for sexual assault cases. - The specific term **"in camera"** is used in Section 327 CrPC and judicial pronouncements, making it the precise medico-legal answer. *Hearing at a different location* - Changing the location does not inherently provide the **legal framework** for privacy protection that in camera proceedings mandate. - This option lacks the formal legal status and procedural safeguards that Section 327 CrPC provides through in camera hearings.

Q: Police brought a person from a railway track with features of dry dilated pupils, dry skin, slurred speech, and altered sensorium. What is the most likely cause of poisoning?

Datura. ***Datura*** - **Datura poisoning** presents with anticholinergic symptoms including **dry dilated pupils**, **dry skin**, **tachycardia**, altered mental status (**altered sensorium**), and **slurred speech**. - The classic mnemonic "hot as a hare, blind as a bat, dry as a bone, red as a beet, mad as a hatter" describes the systemic effects of **anticholinergic toxidrome**. *Morphine* - **Opioid poisoning**, such as with morphine, typically causes **pinpoint pupils**, **respiratory depression**, and **CNS depression**. - Skin is usually **cool and clammy**, not dry. *Cannabis* - **Cannabis intoxication** typically causes **conjunctival injection** (red eyes), **tachycardia**, increased appetite, and euphoria or anxiety. - While it can alter perception, it generally does not lead to significantly **dilated pupils**, dry skin, or profound slurred speech in the manner seen with anticholinergics. *Alcohol* - **Alcohol intoxication** leads to **CNS depression**, slurred speech, ataxia, and sometimes nausea/vomiting. - **Pupils** are typically normal or slightly constricted, and the skin is often flushed and warm, not significantly dry or pale.

Q: A child was born 8 months after the father's death. The grandparents filed a case claiming that the baby is not their son's, but DNA testing confirmed paternity. What is the child called?

Posthumous child. ***Posthumous child*** - A **posthumous child** is one born after the death of its father. - In most legal systems, such a child is considered an heir and has rights equivalent to those born before the father's death, especially after paternity is confirmed. *Suppositious child* - A **suppositious child** is one who is falsely substituted for another, typically with the intent to defraud or claim an inheritance under false pretenses. - This term does not apply here as paternity was confirmed by DNA testing, indicating the child is genuinely linked to the deceased father. *Fabricated child* - The term **fabricated child** implies the child does not exist or was created through fraudulent means, often in the context of false claims or elaborate schemes. - In this scenario, the child is real and paternity has been verified, making "fabricated" an inaccurate description. *Illegitimate child* - An **illegitimate child** is historically defined as one born outside of marriage between its biological parents. - While the father died before the child's birth, the question does not provide information about the parents' marital status, and the term primarily refers to marital legality rather than the circumstances of the father's death.

Q: Examination of a suspicious stain shows the following finding. Which test is being depicted? ![img-21.jpeg](img-21.jpeg)

Takayama test. ***Takayama test*** - The image shows **pinkish, feathery crystals** that are diagnostic of **hemochromogen crystals (heme crystals)**, which are produced in the presence of hemoglobin during the Takayama test. - This test is a confirmatory test for the presence of **blood** and is more sensitive than the Teichmann test, especially with older stains. *Teichmann test* - This test also detects blood by forming **hemin crystals** (dark brown rhomboid crystals) from hemoglobin, but the morphology in the image does not match these. - The Teichmann test can be less reliable with **older or degraded bloodstains** compared to the Takayama test. *Barberio's test* - The Barberio's test is used for the detection of **spermine**, a component of seminal fluid, by forming **yellow, needle-like crystals** with picric acid. - This test is not used for blood detection, and the crystal morphology is distinct from what is shown. *Florence test* - The Florence test is another presumptive test for the presence of **spermine** in seminal fluid, producing **dark-brown, rhombic crystals** when iodine solution is added. - Like the Barberio's test, it is not designed to detect blood, and the crystal appearance is different.

Q: The dead body shows the following finding as seen in the image. What is the most likely cause of death?

Hanging. ***Hanging*** - The image displays a **ligature mark** that is **oblique** and **incomplete**, which is characteristic of hanging due to the upward pull of the ligature - The mark is typically found **high on the neck**, often above the thyroid cartilage - Position of the mark corresponds to the point of suspension - May show vital signs like congestion above the ligature mark *Throttling* - **Throttling** (manual strangulation) involves direct compression of the neck by human hands - Leaves **finger marks**, **bruises**, or **abrasions** on the neck, typically on the sides - Does not produce a ligature mark; instead shows evidence of fingertip pressure - Marks are usually **horizontal** and scattered around the neck *Choking* - **Choking** is obstruction of the internal air passages, usually by **food or foreign objects**, leading to asphyxia - Does not involve external compression of the neck or leave a ligature mark - Diagnosis typically made by finding obstructing material in the airway at autopsy *Smothering* - **Smothering** involves obstruction of the external air passages (mouth and nose), preventing air entry - Usually **no specific marks on the neck**; may show injuries around mouth and nose - Does not involve a ligature or neck compression

Q: In a medicolegal examination, an 18-year-old male claims he is 16 years old. Which joint X-ray should be done to estimate his age?

Knee and wrist. ***Knee and wrist*** - **Bone age determination** using hand/wrist and knee radiographs is a standard method for estimating skeletal maturity across a wide age range, including late adolescence. - The **epiphyseal fusion** in these joints provides reliable indicators for age estimation up to and slightly beyond 18 years, particularly the **distal radius, ulna, and knee epiphyses**. *Head & shoulder* - While glenohumeral fusion occurs later, **skull sutures** are not reliable for precise age estimation in this age group, and shoulder fusion may not be as precise as wrist/knee for this specific age. - The **skull and shoulder** are generally not the primary sites chosen for age estimation in late adolescence due to less distinct and less consistent markers compared to other joints. *Elbow and ankle* - Although the elbow and ankle joints undergo fusion, the **wrist and knee provide a more comprehensive and widely validated set of ossification centers** for age estimation in the 16-18 year old range. - While useful, these sites may not offer the same level of detailed assessment for skeletal maturity as the combination of **wrist and knee**. *Elbow & hip* - **Hip fusion** (e.g., ilium, ischium, pubis) happens relatively early, making it less useful for distinguishing between 16 and 18 years old. - The **elbow alone** may not provide sufficient distinct markers for accurate age estimation in this specific late adolescent age group, unlike the wrist, which has multiple carpal and epiphyseal centers.

Q: A pregnant female at 37 weeks of gestation with a history of prosthetic heart valves is currently taking warfarin. She comes for a routine antenatal check-up. What is the appropriate management advice?

Switch to low molecular weight heparin. ***Switch to low molecular weight heparin*** - **Warfarin** is **teratogenic** and carries a significant risk of **fetal bleeding** and **malformations**, especially close to term. Switching to **low molecular weight heparin (LMWH)** is crucial at 37 weeks. - **LMWH** does not cross the placenta, making it a safer alternative for anticoagulation in late pregnancy for women with prosthetic heart valves. *Immediate induction of labor* - While delivery is approaching, immediate induction of labor without addressing the **warfarin** use directly puts the fetus at high risk of **bleeding complications** during delivery. - This option does not specify concurrent management of the anticoagulation, which is the primary concern. *Perform LSCS (Lower Segment Cesarean Section)* - Similar to induction of labor, performing a C-section while the mother is on **warfarin** significantly increases the risk of **maternal and fetal hemorrhage**. - A C-section is an invasive procedure, and the immediate priority is to switch the anticoagulant rather than select the mode of delivery without addressing the current medication. *Continue the same medication* - Continuing **warfarin** at 37 weeks is highly dangerous due to the increased risk of **fetal intracranial hemorrhage** during labor and delivery. - This approach disregards the well-established **teratogenic effects** and **bleeding risks** associated with warfarin in late pregnancy.

Q: A 25 -year-old male presented to the emergency department with head trauma due to a road traffic accident. In the hospital, the patient developed seizures, and an emergency CT scan revealed widespread cerebral edema. Which of the following is the diuretic of choice for cerebral edema in this patient?

A. Mannitol. ***Mannitol*** - **Mannitol** is an osmotic diuretic that creates an osmotic gradient, drawing water from the brain parenchyma into the intravascular space, thereby reducing **cerebral edema**. - Its rapid onset of action and ability to cross an intact blood-brain barrier sparingly makes it the drug of choice for acute management of elevated intracranial pressure due to **cerebral edema**. *Spironolactone* - **Spironolactone** is a potassium-sparing diuretic that primarily acts on the distal tubules to inhibit aldosterone, leading to sodium and water excretion. - It is unsuitable for acute cerebral edema as its diuretic effect is too slow and it does not create the necessary osmotic gradient. *Furosemide* - **Furosemide** is a loop diuretic that inhibits sodium-potassium-chloride co-transporter in the loop of Henle, leading to significant diuresis. - While it can remove fluid, it does not create the same osmotic gradient as mannitol and is less effective at rapidly reducing **intracranial pressure** directly related to cerebral edema. *Hydrochlorothiazide* - **Hydrochlorothiazide** is a thiazide diuretic that primarily acts on the distal convoluted tubule to inhibit sodium reabsorption. - Its diuretic action is too slow and relatively mild for the acute management of severe conditions like **cerebral edema**. *Acetazolamide* - **Acetazolamide** is a carbonic anhydrase inhibitor that reduces CSF production and has a role in chronic management of idiopathic intracranial hypertension. - However, it is not suitable for acute cerebral edema following trauma as its onset is too slow and its diuretic effect is relatively weak compared to osmotic diuretics.
