NEET-PG 2013 - Forensic Medicine NEET-PG Practice Questions and MCQs
Question 21: According to which of the following guidelines must a registered medical practitioner preserve medical records of patients for a minimum of 3 years from the last date of treatment?
- A. Medical Council of India Act: Professional misconduct and medical ethics (Correct Answer)
- B. Indian Medical Council (Professional Conduct) Regulations: Medical certificate guidelines
- C. Consumer Protection Act: Medical services as consumer services
- D. Section 304A IPC: Death caused by negligence (medical negligence)
Explanation: ***Medical Council of India Act: Professional misconduct and medical ethics*** - The **Professional Conduct, Etiquette, and Ethics Regulations, 2002**, issued under the **Medical Council of India Act**, mandate the preservation of medical records for a minimum of **3 years** from the last date of treatment. - This regulation falls under the purview of **professional misconduct and medical ethics**, outlining the duties and responsibilities of registered medical practitioners. *Indian Medical Council (Professional Conduct) Regulations: Medical certificate guidelines* - While these regulations do describe **medical certificate guidelines**, they do not specifically address the minimum period for preserving general medical records. - This section focuses on the proper issuance and content of **medical certificates**, not storage duration of patient files. *Consumer Protection Act: Medical services as consumer services* - This Act primarily defines **medical services as consumer services** and allows patients to seek redressal for deficiencies in service. - It does not specify the **duration for medical record preservation** by practitioners but rather grants rights to consumers. *Section 304A IPC: Death caused by negligence (medical negligence)* - This section deals with **criminal liability for death caused by negligence**, including medical negligence. - It is a **penal provision** and does not provide guidelines on the administrative aspect of medical practice, such as record keeping duration.
Question 22: Which of the following is NOT a sign of somatic death?
- A. Cessation of heart
- B. No response to external stimuli
- C. Rigor mortis (Correct Answer)
- D. Cessation of respiration
Explanation: ***Rigor mortis*** - **Rigor mortis** is a post-mortem change, occurring hours after death, characterized by muscle stiffening due to chemical changes after somatic death. - While it's a definitive sign of death, it is a secondary change occurring *after* the cessation of vital functions, not a primary sign of **somatic death** itself. *Cessation of respiration* - The complete and irreversible **cessation of respiration** (breathing) is a primary indicator of somatic death, as oxygen supply to tissues is halted. - This signifies the failure of the **respiratory system** to sustain life functions. *Cessation of heart* - The permanent **cessation of heart** function (cardiac arrest) is a fundamental sign of somatic death, leading to a lack of circulation and nutrient/oxygen delivery. - This marks the breakdown of the **circulatory system**, essential for maintaining life. *No response to external stimuli* - The absence of any **response to external stimuli**, including pain, light, and sound, indicates the complete loss of brain function and consciousness. - This signifies the irreversible failure of the **nervous system**, a key component of somatic death.
Question 23: Which traditional method is considered most reliable for personal identification in forensic science?
- A. Gustafson's method
- B. Anthropometry
- C. DNA profiling
- D. Galton method (Correct Answer)
Explanation: ***Galton method*** - The **Galton method**, which refers to **fingerprint analysis**, is considered a highly reliable traditional method for personal identification due to the uniqueness and permanence of fingerprints. - No two individuals, even identical twins, have been found to have the exact same **fingerprint patterns**, making it a robust identifier. *Gustafson's method* - **Gustafson's method** is a technique used for **age estimation based on dental changes**, not for definitive personal identification. - While it provides an estimate of age, it cannot uniquely identify an individual. *DNA profiling* - **DNA profiling** is indeed the most reliable method for personal identification in modern forensic science, but it is not considered a "traditional" method. - The question specifically asks for a **traditional method**, distinguishing it from newer genetic techniques. *Anthropometry* - **Anthropometry** involves the measurement of the **human body and its parts**, often used for classification or to establish demographic profiles. - It is not reliable for unique personal identification as many individuals share similar physical measurements.
Question 24: Minamata disease is caused by toxicity of:
- A. Arsenic
- B. Antimony
- C. Lead
- D. Mercury (Correct Answer)
Explanation: ***Mercury (Correct Answer)*** - Minamata disease is a severe neurological syndrome caused by **mercury poisoning**, specifically from the consumption of fish and shellfish contaminated with **methylmercury**. - The disease was first identified in Minamata Bay, Japan, resulting from the release of industrial wastewater containing methylmercury. - **Clinical features** include: ataxia, dysarthria, constriction of visual fields, sensory disturbances, and in severe cases, convulsions and death. *Arsenic (Incorrect)* - **Arsenic poisoning** is associated with symptoms like **garlic breath**, skin lesions (hyperkeratosis, Raindrop pigmentation), and neurological damage, but it does not cause Minamata disease. - Exposure typically occurs through contaminated water or occupational settings. *Antimony (Incorrect)* - **Antimony toxicity** can manifest with symptoms such as nausea, vomiting, cardiac arrhythmias, and skin inflammation. - It is not linked to the distinct neurological syndrome known as Minamata disease. *Lead (Incorrect)* - **Lead toxicity** (plumbism) primarily affects the nervous system, kidneys, and hematopoietic system, leading to symptoms like **abdominal pain**, **wrist drop/foot drop**, and anemia. - While it causes neurological damage, it has a different clinical presentation and is not associated with Minamata disease.
Question 25: Which one of the tissues putrefies late?
- A. Prostate (Correct Answer)
- B. Liver
- C. Brain
- D. Stomach
Explanation: ***Prostate*** - The **prostate** is a glandular organ that contains a significant amount of **fibrinous connective tissue**, which is less susceptible to rapid decomposition. - Its relatively **acidic internal environment** also contributes to slower bacterial proliferation and, therefore, delayed putrefaction compared to other organs. *Liver* - The **liver** is rich in **parenchymal cells** and blood, making it a good substrate for bacterial growth and enzymatic degradation leading to early putrefaction. - Its metabolic activity continues shortly after death, releasing enzymes that contribute to **autolysis** and subsequent putrefaction. *Brain* - The **brain** has a high **water and lipid content**, which makes it highly susceptible to rapid autolysis, particularly by its own lysosomal enzymes. - It also has a rich blood supply, providing ample nutrients for **anaerobic bacteria**, accelerating decomposition. *Stomach* - The **stomach** contains a high concentration of **digestive enzymes** (e.g., pepsin, hydrochloric acid) which, post-mortem, contribute to rapid autolysis of its own tissues. - The presence of food contents and abundant bacteria within the stomach lumen further accelerates the process of **putrefaction**.
Question 26: Dilated pupil with coma is seen in which poisoning?
- A. Opium
- B. Mushroom
- C. Dhatura (Correct Answer)
- D. Pilocarpine
Explanation: ***Dhatura*** - **Dhatura poisoning** is characterized by an **anticholinergic toxidrome**, leading to symptoms like **dilated pupils (mydriasis)**, dry mouth, flushed skin, tachycardia, and altered mental status progressing to coma. - The dilated pupils are a direct result of the **muscarinic receptor blockade** in the eye, preventing parasympathetic innervation. *Opium* - **Opium poisoning** typically causes **pinpoint pupils (miosis)**, respiratory depression, and central nervous system depression leading to coma. - This effect is due to the **opioid agonists** stimulating mu-opioid receptors. *Mushroom* - Mushroom poisoning can present with various toxidromes depending on the species; however, some muscarine-containing species can cause **miosis** (pinpoint pupils), salivation, and bradycardia, while others may cause delirium or hepatic failure. - **Dilated pupils** are not a characteristic feature of the more common deadly mushroom poisonings that lead to coma. *Pilocarpine* - **Pilocarpine** is a **direct cholinergic agonist** that stimulates muscarinic receptors and typically causes **miosis (constricted pupils)**, increased secretions, and bradycardia. - It would not lead to dilated pupils or coma in the manner described.
Question 27: Concealment of birth is punishable under:
- A. Sec. 320 IPC
- B. Sec. 318 IPC (Correct Answer)
- C. Sec. 317 IPC
- D. Sec. 312 IPC
Explanation: ***Sec. 318 IPC*** - This section of the **Indian Penal Code (IPC)** specifically deals with the **concealment of birth by secret disposal of dead body**. - It punishes anyone who, by **secretly burying or otherwise disposing of the dead body of a child**, endeavors to conceal the birth of the child. *Sec. 320 IPC* - This section defines **"grievous hurt"** under the IPC. - It lists various types of injuries that constitute grievous hurt, such as **emasculation**, permanent privation of sight or hearing, fracture or dislocation of a bone, etc., and is unrelated to concealment of birth. *Sec. 317 IPC* - This section pertains to the **exposure and abandonment of a child under twelve years** of age by a parent or person having care of it. - While it deals with offenses against a child, it specifically addresses abandonment rather than the concealment of a dead body after birth. *Sec. 312 IPC* - This section addresses **causing miscarriage**. - It punishes anyone who voluntarily causes a woman with child to miscarry, which is distinct from the act of concealing a birth by disposing of a dead child's body.
Question 28: Marshall's triad is seen in:
- A. Lightning injury
- B. Explosive injury (Correct Answer)
- C. Gunshot injury
- D. Drowning injury
Explanation: ***Explosive injury*** - Marshall's triad components, including **blast lung**, **abdominal hemorrhage**, and **tympanic membrane rupture**, are characteristic injuries of explosions, especially those involving pressure waves. - The triad highlights distinct patterns of organ damage caused by the high-energy transfer from blast forces. *Lightning injury* - Lightning injuries can cause diverse effects like **cardiac arrest**, **neurological damage**, and **burns**, but they do not typically present as Marshall's triad. - The primary mechanism is electrical, leading to distinct injury patterns different from blast trauma. *Gunshot injury* - Gunshot wounds create localized tissue damage along the projectile's path and a temporary cavity, but they do not cause generalized blast effects or the specific triad of Marshall. - The injury severity depends on the **caliber**, **velocity**, and **trajectory** of the bullet. *Drowning injury* - Drowning is characterized by **respiratory impairment** resulting from submersion or immersion in liquid, leading to **hypoxia** and multi-organ failure. - Its pathophysiology and presentation are entirely distinct from explosive trauma.
Question 29: Which of the following snakes is most commonly associated with hematologic abnormalities following envenomation?
- A. Sea snake
- B. Krait
- C. Viper (Correct Answer)
- D. Cobra
Explanation: ***Correct Answer: Viper*** - **Viper venom** contains **hemotoxic components** including **metalloproteinases** and **serine proteinases** that directly activate clotting factors - This leads to **consumptive coagulopathy** characterized by **thrombocytopenia**, **hypofibrinogenemia**, and prolonged coagulation times - Clinical manifestations include spontaneous **bleeding**, **ecchymoses**, **hemorrhage** at the bite site, and in severe cases, **disseminated intravascular coagulation (DIC)** - Viper envenomation is the **classic cause** of hematologic abnormalities among snake bites *Incorrect: Sea snake* - Sea snake venoms are primarily **neurotoxic** and **myotoxic**, causing paralysis and muscle damage - While they can cause **rhabdomyolysis** and subsequent **renal failure**, significant primary hematologic abnormalities are not their hallmark feature *Incorrect: Krait* - Krait venom is predominantly **neurotoxic**, leading to **flaccid paralysis** and **respiratory failure** - Does not typically cause the significant widespread **coagulopathies** seen with viper envenomation *Incorrect: Cobra* - Cobra venom primarily contains **neurotoxins** and **cytotoxins**, causing **paralysis**, **tissue necrosis**, and localized pain - While some cobras can cause minor local bleeding, they do not generally induce the severe and systemic **hematologic abnormalities** characteristic of viper bites
Question 30: Contributory negligence is negligence due to:
- A. Doctor only
- B. Both doctor and patient
- C. Hospital administrator and doctor
- D. Patient only (Correct Answer)
Explanation: ***Patient only*** - **Contributory negligence** specifically refers to negligence on the part of the **plaintiff** (the patient) that contributed to their own injury. - This doctrine can reduce or bar recovery for damages if the patient's own actions played a role in causing the harm. *Doctor only* - This describes **medical malpractice**, where the healthcare provider's negligence directly causes harm to the patient. - While a doctor's negligence is a primary concern in healthcare, it doesn't align with the legal concept of *contributory* negligence, which attributes fault to the injured party. *Both doctor and patient* - This scenario relates to **comparative negligence**, a legal doctrine where fault is apportioned between multiple parties (e.g., doctor and patient). - Contributory negligence, in its strict form, implies the patient's negligence alone contributed significantly enough to preclude full recovery, rather than shared fault. *Hospital administrator and doctor* - This refers to negligence stemming from actions of the hospital administration (e.g., systemic failures, inadequate resources) and individual medical errors by the doctor. - While both can be liable for negligence, this does not represent the patient's own contribution to their injury, which is the core of contributory negligence.
