Question 1361: Testamentary capacity refers to:
- A. Right to vote
- B. Ability to give evidence
- C. Ability to make a valid will (Correct Answer)
- D. Criminal liability
Explanation: ***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.
Question 1362: Which of the following is NOT a characteristic feature of close-range shotgun wounds?
- A. Contact wound with stellate laceration
- B. Beveling of bone at exit wound (Correct Answer)
- C. Abrasion collar around entry wound
- D. Powder tattooing around entry wound
Explanation: ***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
Question 1363: Rectified spirit is NOT used as preservative in case of:
- A. Phenol (Correct Answer)
- B. Cyanide
- C. Alphos
- D. Insecticides
Explanation: ***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.
Question 1364: In an incised wound, all of the following are true, except:
- A. Tailing is often present
- B. It has clean-cut margins
- C. Bleeding is generally less than in lacerations (Correct Answer)
- D. Length of injury does not correspond with length of blade
Explanation: ***Bleeding is generally less than in lacerations*** - Incised wounds, due to their **clean-cut nature** and often transected blood vessels, typically result in **more profuse external bleeding** compared to lacerations. - Lacerations often have torn vessels and crushed tissue, which can promote **hemostasis** to some degree, leading to less external bleeding than deep incised wounds. *Tailing is often present* - **Tailing** refers to the superficial beginning and ending of an incised wound, appearing as a shallow scratch. - This feature is characteristic of incised wounds created by a **sharp object drawn across the skin**. *It has clean-cut margins* - Incised wounds are caused by **sharp-edged instruments** that slice through tissue, resulting in margins that are smooth, sharp, and without significant tissue damage. - The absence of crushing or tearing around the wound edges is a hallmark of an incised wound. *Length of injury does not correspond with length of blade* - The length of an incised wound can often be **longer than the width of the blade** (e.g., a small knife producing a long wound) or **shorter than the blade's full length** if only a part of the blade comes into contact with the skin. - This lack of direct correlation is important for forensic analysis in determining the nature of the weapon.
Question 1365: What is the maximum punishment under Section 304-A IPC for causing death by negligence?
- A. 3 years
- B. 2 years (Correct Answer)
- C. 1 year
- D. 4 years
Explanation: **2 years** - Section 304A of the **Indian Penal Code (IPC)** specifically dealt with causing **death by negligence** and prescribed a maximum imprisonment of **two years** (as per law applicable in 2015). - This section was applied in cases where death was caused by a rash or negligent act not amounting to culpable homicide. - **Note:** Section 304A IPC has been replaced by Section 106 of the Bharatiya Nyaya Sanhita (BNS) 2023, which prescribes a maximum of 5 years imprisonment. However, for this NEET-2015 question, the answer reflects the law as it existed at that time. *3 years* - While some offenses in the IPC carried a punishment of 3 years, **death by negligence** under Section 304A did not fall into this category (as per 2015 law). - More severe forms of culpable homicide not amounting to murder would attract higher penalties, but not simple negligence. *1 year* - A punishment of **one year** was too lenient for causing death by negligence, as the potential harm is significant. - The law recognized the gravity of causing death, even if unintentional, by imposing a more substantial penalty. *4 years* - A punishment of **four years** would have extended beyond the maximum prescribed limit for causing death by negligence under **Section 304A IPC** (as per 2015 law). - Such a sentence would typically be reserved for more serious offenses with a higher degree of intent or culpability.
Question 1366: Sec. 176 CrPC is related to?
- A. Summons
- B. Coroner inquest
- C. Magistrate inquest (Correct Answer)
- D. Police inquest
Explanation: ***Magistrate inquest*** - Section 176 of the CrPC (Code of Criminal Procedure) specifically deals with the **inquiry by a Magistrate into the cause of death** in certain circumstances. - This section outlines the powers and procedures for a Magistrate to hold an inquest, particularly in cases involving death in police custody, or where there is suspicion of foul play, etc. *Summons* - Summons are dealt with under a different part of the CrPC, primarily starting from **Section 61**, which details the form and service of summons. - They are legal documents compelling an individual to appear in court, and are not related to the inquiry into the cause of death. *Coroner inquest* - While coroner inquests serve a similar purpose of inquiring into the cause of death, the term "coroner" is not primarily used in the Indian legal system; instead, **Magistrates primarily conduct such inquiries**. - The procedure and authority for these inquiries are laid out in the CrPC, which designates the role to Magistrates rather than coroners. *Police inquest* - Police inquests are conducted under **Section 174 CrPC**, where the police investigate the apparent cause of death, often in cases of suicide, accidental death, or when there is doubt about the cause. - While police conduct an initial inquiry and prepare a report, a Magistrate's inquest under Section 176 comes into play when there are specific suspicious circumstances or custodial deaths, providing an additional layer of scrutiny.
Question 1367: A witness, who after taking oath, willfully makes a statement which he knows or believes to be false is guilty of offence under section:
- A. 192 IPC
- B. 193 IPC (Correct Answer)
- C. 191 IPC
- D. 190 IPC
Explanation: ***193 IPC*** - **Section 193 of the Indian Penal Code (IPC)** is the substantive offense provision that prescribes **punishment for giving false evidence** in a judicial proceeding. - Making a false statement under oath, knowing it to be false, makes a person **guilty under Section 193 IPC**, which provides for imprisonment up to 7 years and fine. - This is the operative section under which prosecution is initiated for perjury. *191 IPC* - **Section 191 IPC** defines what constitutes "giving false evidence" - it describes the act but does not prescribe punishment. - While the question describes an act that fits Section 191's definition, the person is charged and found guilty under **Section 193**, which is the punishment provision. - Section 191 is a definitional section, not the offense section itself. *192 IPC* - **Section 192 IPC** deals with **fabricating false evidence**, which involves creating or manufacturing evidence (making false entries in documents, causing circumstances to exist, etc.). - This focuses on the act of *fabricating* rather than directly *giving* a false statement under oath in proceedings. *190 IPC* - **Section 190 IPC** deals with **threat of injury** to induce a person to refrain from applying for protection to a public servant. - This section is entirely unrelated to giving false evidence or making false statements under oath.

NEET-PG 2015 - Physiology NEET-PG Practice Questions and MCQs
Question 1361: Which of the following is not true about sleep -
- A. Dreams come in REM sleep
- B. REM sleep comes earlier than NREM sleep (Correct Answer)
- C. REM sleep is also called paradoxical sleep
- D. Sleep walking comes in NREM sleep
Explanation: ***REM sleep comes earlier than NREM sleep*** - This statement is **incorrect** because the sleep cycle typically begins with **NREM (non-rapid eye movement) sleep**, specifically NREM stage 1, before progressing to NREM stages 2 and 3, and then finally entering REM sleep. - NREM sleep accounts for about **75% of total sleep time** and occurs prior to REM sleep in a typical nocturnal sleep episode. *Dreams come in REM sleep* - This statement is **true** as **vivid, memorable dreams** are most commonly associated with **REM sleep**. - During REM sleep, brain activity significantly increases, mimicking the awake state, which facilitates complex dream formation. *REM sleep is also called paradoxical sleep* - This statement is **true** because **REM sleep** is characterized by **high brain activity** (similar to wakefulness) and rapid eye movements, yet the body experiences **muscle atonia**, leading to a state of profound relaxation. - This paradoxical combination of an active brain and a paralyzed body gives it the name **paradoxical sleep**. *Sleep walking comes in NREM sleep* - This statement is **true** as **sleepwalking (somnambulism)** typically occurs during **slow-wave sleep**, which is **NREM stage 3 (deep sleep)**. - During this stage, arousal thresholds are very high, and complex motor behaviors can occur while the individual remains in a sleep state.
Psychiatry
1 questionsIn forensic medicine and clinical documentation, what term describes the receptive partner in cases of sexual abuse involving same-sex perpetrators and victims?
NEET-PG 2015 - Psychiatry NEET-PG Practice Questions and MCQs
Question 1361: In forensic medicine and clinical documentation, what term describes the receptive partner in cases of sexual abuse involving same-sex perpetrators and victims?
- A. Sodomite
- B. Pederast
- C. Ephebophile
- D. Catamite (Correct Answer)
Explanation: ***Catamite*** - This term historically refers to the **passive** or **receptive partner** in a same-sex sexual relationship, particularly with an older male. - In forensic contexts, it specifically denotes the person who is the **recipient of sexual penetration** in cases of child sexual abuse by a male perpetrator. *Sodomite* - This term is a broad, often pejorative, historical term primarily used to describe individuals engaging in what was considered **non-procreative sexual acts**, including anal sex. - It does not specifically denote the receptive partner in a sexual abuse context, nor does it inherently imply abuse. *Pederast* - A pederast refers to an adult male who has a **sexual attraction to or engages in sexual acts with a pre-pubescent boy**. - This term specifically identifies the **perpetrator** in such a relationship, not the receptive victim. *Ephebophile* - An ephebophile refers to an adult who is primarily sexually attracted to **adolescents** (typically between ages 11 and 14). - Like pederast, this term describes the **perpetrator** and their sexual preference for a specific age group, not the receptive partner in an abusive situation.

NEET-PG 2015 - Surgery NEET-PG Practice Questions and MCQs
Question 1361: What is the most common site of injury in an underwater blast?
- A. Lung
- B. GIT (Correct Answer)
- C. Tympanic membrane
- D. Liver
Explanation: ***GIT (Correct Answer)*** - The **gastrointestinal tract (GIT)** is the most common site of injury in an underwater blast due to the presence of air-filled organs that are highly susceptible to pressure changes. - The **rupture of hollow viscera** such as the stomach and intestines can lead to severe abdominal pain, hemorrhage, and peritonitis. - Underwater blasts transmit pressure waves efficiently through water, causing maximum damage to air-filled hollow organs. *Lung (Incorrect)* - While **pulmonary barotrauma** can occur, the lungs are less frequently injured compared to the GIT in underwater blasts unless unprotected or subjected to severe pressure. - Lung injuries may manifest as **pneumothorax**, pulmonary contusions, or air embolism. *Tympanic membrane (Incorrect)* - The **tympanic membrane** is the most frequently ruptured structure in blast injuries and highly vulnerable to pressure changes. - However, while common, it is not the most common site of **major organ damage** or life-threatening injury in an underwater blast scenario. *Liver (Incorrect)* - The **liver**, being a solid organ, is less susceptible to direct blast injury from pressure waves compared to air-filled organs. - Liver injury is more likely to result from secondary effects such as blunt trauma from impact against objects or deceleration forces.
