NEET-PG 2015 - Forensic Medicine Practice Questions

Q: Which vein is most commonly used for blood collection during post-mortem examinations?

Femoral vein. ***Femoral vein*** - The **femoral vein** in the groin region is frequently chosen for post-mortem blood collection because it is large, superficial, and easily accessible, even in cases of significant trauma or decomposition. - Blood from the femoral vein is generally considered less prone to **post-mortem redistribution** of drugs and endogenous substances compared to central veins. *Antecubital vein* - The **antecubital vein** (in the elbow crease) is a common site for blood collection in living individuals but is less preferred post-mortem due to its smaller size and potential for damage or disfigurement during autopsy. - Its accessibility can be limited depending on the body's condition and positioning during a post-mortem examination. *Jugular vein* - While large, the **jugular vein** in the neck is generally less preferred for routine post-mortem blood collection than the femoral vein due to its proximity to the heart and great vessels. - Blood samples from the jugular vein may be more significantly affected by **post-mortem redistribution** of substances due to fluid shifts. *Carotid artery* - The **carotid artery** is an artery, not a vein, and is typically avoided for routine post-mortem blood collection unless specific arterial samples are required. - Accessing an artery can be more challenging and may provide blood that is less representative of general systemic circulation compared to venous samples for toxicology.

Q: During a postmortem examination of a young adult found with a faded tattoo, relatives mentioned that the tattoo was once visible. What is the best method to identify the tattoo?

Illuminate with ultraviolet (UV) light. ***Illuminate with ultraviolet (UV) light*** - **UV light** causes residual tattoo pigments, even faded ones, to **fluoresce**, making them visible again for identification. - This method is particularly effective for **older or faded tattoos** where the pigment has degraded or spread. *Use a spectrophotometer for analysis* - A spectrophotometer is used to measure the **intensity of light** as a function of wavelength, which is useful for **analyzing chemical components or color intensity**. - While it can analyze pigments, it is not the primary or most practical method for merely **identifying the presence and pattern of a faded tattoo** on skin, especially in a postmortem context. *Illuminate with ordinary light* - **Ordinary visible light** is typically insufficient to reveal tattoos that have significantly faded or been subjected to processes that obscure them. - If the tattoo is already faded to the point of being invisible to the naked eye, **ordinary light will not enhance its visibility** as it lacks the specific wavelengths needed to cause fluorescence. *Perform an X-ray examination* - **X-rays** are used to visualize dense structures like **bones and foreign bodies**, not for examining skin or pigments. - Tattoo pigments are generally **not radiopaque** and would not be visible on an X-ray film, rendering this method useless for tattoo identification.

Q: Which of the following is not a postmortem change:

Atria mortis. ***Atria mortis*** - *Atria mortis* is not a recognized postmortem change; it appears to be a **nonsensical or fabricated term**. - **Postmortem changes** are a well-defined set of physical and chemical alterations that occur in a body after death. *Livor mortis* - This is a postmortem change characterized by the **reddish-purple discoloration** of the skin due to the settling of blood in capillaries under gravity. - It occurs after circulation ceases and typically becomes visible within 30 minutes to 2 hours after death. *Algor mortis* - This refers to the **postmortem cooling of the body** until it reaches ambient temperature. - The rate of cooling is influenced by environmental factors and body size, and it is used to estimate the time of death. *Rigor mortis* - This is the **stiffening of muscles** after death due to the depletion of ATP, preventing the separation of actin and myosin filaments. - It usually begins 2-4 hours after death, reaches maximum stiffness at 8-12 hours, and resolves within 24-36 hours due to muscle decomposition.

Q: Prohibition of participation in torture by a doctor comes under:

Declaration of Tokyo. ***Declaration of Tokyo*** - The **Declaration of Tokyo (1975)** specifically addresses the **prohibition of participation by doctors in torture** and other cruel, inhuman, or degrading treatment. - It mandates that physicians must not condone, facilitate, or participate in any form of torture, even under threat or duress. *Declaration of Helsinki* - This declaration focuses primarily on **ethical principles for medical research involving human subjects**. - It sets guidelines for **informed consent**, risk-benefit assessment, and the protection of vulnerable populations in research. *Declaration of Oslo* - The Declaration of Oslo (1970) deals with **therapeutic abortion** and the ethical considerations surrounding it. - It provides guidance on the physician's role and responsibilities when considering termination of pregnancy. *Declaration of Geneva* - Often referred to as a modern Hippocratic Oath, the Declaration of Geneva (1948) outlines the **general ethical duties of physicians**. - It emphasizes core principles such as respect for human life, professional secrecy, and beneficence, but does not specifically detail prohibitions regarding torture.

Q: Vitriolage is punishable under which section?

Sec. 326-A IPC. ***Sec. 326-A IPC*** - This section specifically deals with the offense of voluntarily causing **grievous hurt by use of acid**, or commonly referred to as **vitriolage**. - It prescribes a stringent punishment of imprisonment which shall not be less than ten years but which may extend to imprisonment for life, and with fine. *Sec. 320 IPC* - This section defines what constitutes **"grievous hurt"** under the Indian Penal Code. - It does not prescribe punishment but rather lists categories of injuries considered grievous, such as **emasculation**, **loss of sight/hearing**, or **fracture of bone**. *Sec. 304-A IPC* - This section deals with **causing death by negligence**, which is a distinct offense from intentionally causing harm. - It applies in cases where there is no intention to cause death, but death occurs due to a rash or negligent act. *Sec. 326 IPC* - This section addresses **voluntarily causing grievous hurt by dangerous weapons or means**. - While acid can be considered a dangerous means, Section 326-A was specifically introduced to deal with acid attacks due to their severe and often permanent consequences.

Q: When a doctor issues a false medical certificate, then he is liable under:

Sec. 197 IPC. ***Sec. 197 IPC*** - This section of the Indian Penal Code specifically deals with issuing or signing a false certificate by a person who is by law bound or authorized to issue such a certificate. - A medical doctor is legally authorized to issue medical certificates, and if they issue a false one, they are liable under this section. *Sec. 420 IPC* - This section pertains to **cheating and dishonestly inducing delivery of property**, which is not the direct offense committed by issuing a false medical certificate. - While a false certificate could potentially lead to cheating, the primary and specific offense related to the certificate itself is covered by other sections. *Sec. 466 IPC* - This section deals with **forgery of a record of a court of justice or of a public register**, etc. - Issuing a false medical certificate does not fall under the category of forging court records or public registers. *Sec. 193 IPC* - This section addresses **punishment for false evidence** given in a judicial proceeding or fabricating false evidence for use in such a proceeding. - While a false medical certificate might be used as false evidence, Section 197 IPC directly addresses the act of *issuing the false certificate* itself, rather than its subsequent use in court.

Q: Rules for criminal responsibility of the insane are all, except:

Curren's rule. ***Curren's rule*** - There is no recognized legal or psychiatric principle referred to as "Curren's rule" related to criminal responsibility for the insane. - This option is likely a distractor, as the other rules listed are established legal doctrines in this area. *McNaughten's rule* - This rule, originating from **English common law**, asserts that a defendant is not criminally responsible if, at the time of the offense, they were suffering from a **defect of reason** from a disease of the mind, such that they did not know the nature and quality of the act, or if they did know it, that they did not know what they were doing was wrong. - It is one of the oldest and most widely recognized tests for **insanity** in criminal law. *ALI rule* - The **American Law Institute (ALI) rule** states that a person is not responsible for criminal conduct if, at the time of such conduct as a result of mental disease or defect, they lack substantial capacity either to **appreciate the criminality (wrongfulness)** of their conduct or to conform their conduct to the requirements of the law. - This rule is more lenient than McNaughten's, incorporating both **cognitive** and **volitional** elements (i.e., the ability to control one's behavior). *Durham's rule* - The **Durham rule** (or "product test") states that an accused is not criminally responsible if their unlawful act was the **product of mental disease or mental defect**. - This rule has been largely abandoned due to its broadness and difficulty in defining what constitutes a "product" of mental illness, leading to overly inclusive interpretations of insanity.

Q: Testamentary capacity refers to:

Ability to make a valid will. ***Ability to make a valid will*** - **Testamentary capacity** is a legal term describing the mental ability a person must have to make or alter a valid will. - It involves understanding the nature of the act, the extent of one's property, and the natural objects of one's bounty (i.e., who would normally inherit). *Right to vote* - The **right to vote** is known as suffrage and is governed by electoral laws, which are distinct from the legal requirements for making a will. - This capacity is related to citizenship and age, not the complex cognitive functions required for testamentary capacity. *Ability to give evidence* - The capacity to give **evidence** in court is known as witness competency, which assesses a person's ability to perceive, remember, and communicate events accurately. - While both involve mental faculties, the specific legal criteria and context for giving evidence differ from those for making a will. *Criminal liability* - **Criminal liability** refers to being held responsible for a crime and depends on factors such as mens rea (guilty mind) and actus reus (guilty act). - This concept is entirely separate from the civil legal concept of creating a valid will.

Q: Which of the following is NOT a characteristic feature of close-range shotgun wounds?

Beveling of bone at exit wound. ***Beveling of bone at exit wound*** - **Beveling of bone is NOT a characteristic feature specific to close-range shotgun wounds** - Beveling relates to the **projectile-bone interaction** and the mechanics of bone perforation, not the range of fire - **Internal (exit) beveling** occurs when the projectile creates a cone-shaped defect as it exits the bone, occurring at **any firing distance** when bone is perforated - This is a feature determined by **projectile trajectory and energy**, not by whether the wound is close-range or distant *Contact wound with stellate laceration* - This is **highly characteristic** of contact or very close-range shotgun wounds (muzzle pressed against skin) - The **hot gases expand beneath the skin** causing irregular, star-shaped (stellate) tearing - Classic forensic finding in contact shotgun wounds *Powder tattooing around entry wound* - **Powder tattooing (stippling) IS characteristic** of close-range shotgun wounds - Occurs at **intermediate range (typically 6 inches to 3 feet)** where unburnt powder grains embed in the skin - Creates a characteristic pattern of small abrasions and contusions around the entry wound - Absent only in contact wounds (powder driven into wound) or distant wounds (powder disperses) *Abrasion collar around entry wound* - **Abrasion collar IS characteristic** of close-range shotgun wounds (and most gunshot wounds) - Results from the **bullet or pellets abrading the skin** as they enter - Creates a rim of scraped epidermis around the wound margin - Present in both close-range and distant shotgun wounds

Q: Rectified spirit is NOT used as preservative in case of:

Phenol. ***Phenol*** - Rectified spirit is **NOT used** for preserving specimens containing **phenol** because phenol is a **volatile poison**. - When mixed with alcohol, phenol can **evaporate** or undergo chemical interactions, leading to loss of the poison and inaccurate toxicological analysis. - Due to this **chemical incompatibility**, phenol specimens should be preserved by **refrigeration without chemical preservatives** or in specific non-alcoholic media. *Cyanide* - Rectified spirit is commonly used as a preservative for specimens involving **cyanide** poisoning cases. - It helps in preventing putrefaction while the specimen is awaiting toxicological analysis. *Alphos* - **Alphos** (aluminum phosphide) poisoning cases often require tissue or organ preservation. - Rectified spirit can be used to preserve tissues, facilitating subsequent analysis for phosphine gas or its metabolites. *Insecticides* - In cases involving **insecticide** poisoning, rectified spirit is a standard preservative for biological samples. - It helps maintain the integrity of the sample, allowing for accurate detection and quantification of various insecticide compounds.
