Injuries and Their Significance Indian Medical PG Practice Questions and MCQs
Question 491: As per Bharatiya Nyaya Sanhita (BNS), which of the following is not classified as grievous hurt?
- A. Emasculation
- B. Severe body pain for 5 days (Correct Answer)
- C. Dislocation of elbow
- D. Loss of a member
Explanation: ***Severe body pain for 5 days*** - Grievous hurt requires a specific threshold of duration, which is **severe body pain** or inability to follow ordinary pursuits for a period of **twenty days** or more, as per the definition in the Bharatiya Nyaya Sanhita (BNS) Section 122. Five days of severe pain does not meet this criterion. - This injury would typically be classified as **simple hurt**, which involves pain, disease, or infirmity, but does not meet the specified severity criteria for grievous hurt. *Emasculation* - **Emasculation** (deprivation of the power of procreation) is explicitly listed as the first clause defining **grievous hurt** in BNS Section 122 (formerly IPC Section 320). - Legal definitions of grievous hurt include eight specific types of injuries that are presumed to be severe. *Dislocation of elbow* - **Fracture or dislocation** of a bone or tooth is explicitly defined as an instance of **grievous hurt** under BNS Section 122. - A dislocation of a major joint like the elbow falls under this specified clause of grievous hurt. *Loss of a member* - The **privation of any member or joint** (loss of a limb, eye, ear, etc.) is specifically enumerated as a clause defining **grievous hurt** in BNS Section 122. - This category includes any injury that permanently impairs a significant part of the body's structure or function.
Question 492: Identify the seeds shown below that produce artificial bruises with their juice? (Recent NEET Pattern 2016-17)
- A. Nux vomica
- B. Calotropis
- C. Ricinus communis
- D. Semecarpus anacardium (Correct Answer)
Explanation: ***Semecarpus anacardium*** - The juice of *Semecarpus anacardium* (also known as **marking nut** or **bhilawa**) contains **bhilawanol**, a vesicant oil that causes severe **blistering and inflammation** on contact with skin. - This irritant effect leads to dark, reddish-brown stains that can mimic **contusions or bruises**, hence its use in creating "artificial bruises" for forensic purposes or in cases of simulated injury. *Nux vomica* - *Nux vomica* seeds contain **strychnine** and **brucine**, potent neurotoxins that primarily affect the central nervous system, leading to **convulsions and muscle spasms**. - Its effects are systemic and neurological, and it does not produce localized skin reactions resembling bruises. *Calotropis* - *Calotropis* plants, such as *Calotropis gigantea* (giant milkweed), contain **cardiac glycosides** that are highly toxic if ingested. - While contact with the latex can cause skin irritation, it typically presents as **redness and stinging** rather than dark, bruise-like lesions. *Ricinus communis* - *Ricinus communis* (castor bean) seeds contain **ricin**, a highly potent **protein toxin** that inhibits protein synthesis in cells and can be fatal if ingested or inhaled. - Although the plant can cause allergic reactions on contact, its primary toxic effect is systemic and it does not produce artificial bruises.
Question 493: The following injury is caused due to:
- A. Marks made by Electrical cardioversion
- B. Bite marks
- C. Laceration
- D. Bullet graze (Correct Answer)
Explanation: ***Bullet graze*** - The image shows a **superficial injury** with a central darkened area that suggests a **contact wound** or a **graze** where the bullet skimmed the skin, leaving a contusion and abrasion. Powder tattooing, or **stippling**, often accompanies such injuries from close range. - The pattern of injury, including the shape and discoloration, is consistent with the kinetic energy transfer of a bullet that did not fully penetrate but rather **scraped across the skin's surface**. *Marks made by Electrical cardioversion* - **Cardioversion marks** typically appear as symmetrical, often circular or oval, burns or erythema from the paddles, usually on the chest or back, which does not match the irregular, abrasive appearance in the image. - Electrical burns are characterized by a **distinct charring** or deep tissue damage at the site of contact, which is different from the superficial abrasion seen here. *Bite marks* - **Bite marks** typically present as indentations or abrasions arranged in an arc or oval pattern, corresponding to the teeth of the aggressor. - The injury in the image does not show a clear dental pattern but rather a more irregular, **abraded surface**. *Laceration* - A **laceration** is a tear in the skin, often irregular and deep, typically caused by a blunt force trauma. - While there is some tearing, the primary appearance is more of a **surface abrasion** with associated discoloration, rather than a deep, gapping wound characteristic of a pure laceration.
Question 494: A 25-year-old person was repairing the power plug of a geyser at home when he was electrocuted and died. The image shows:
- A. Joule burn (Correct Answer)
- B. Spark lesion
- C. Crocodile skin
- D. Scald
Explanation: ***Joule burn*** - This lesion is characteristic of an **electrical burn**, also known as a Joule burn or true electrical burn. The intense heat is generated by the passage of electrical current through body tissues (I²R heating), causing direct tissue destruction. - The appearance often includes a **central area of charring or necrosis** (dark, leathery, or blackened tissue) with a raised, crater-like edge, typically seen at entry and exit points of electrical current. *Spark lesion* - A spark lesion is typically a **smaller, superficial burn** caused by a momentary electrical arc or spark that jumps from conductor to skin without current passing through the body. - It usually presents as a **punctate or minor skin defect** with superficial charring and does not involve the extensive, deep tissue damage seen in Joule burns. *Crocodile skin* - "Crocodile skin" is a specific pattern seen in **high-voltage electrical injuries** where the epidermis separates and peels in a characteristic, polygonal pattern resembling crocodile hide. - This is a distinct manifestation of electrical injury, but the question describes a classic Joule burn with entry/exit point characteristics rather than this specific epidermal pattern. *Scald* - A scald is a burn caused by **hot liquid or steam**. - The appearance of scalds typically involves **blistering, redness, and peeling skin**, which is distinctly different from the charred, leathery appearance seen in electrical burns.
Question 495: An electrician was repairing the main power line in the rainy season when he got electrocuted and died. The image of hand shows:
- A. Joule burn (Correct Answer)
- B. Spark lesion
- C. Crocodile skin
- D. Scald
Explanation: ***Joule burn*** - This image displays a characteristic appearance described as a **Joule burn** or ohmic burn, often seen at the **entry and exit points of electrical current** in the body. - The white, raised, and sometimes charred appearance with localized tissue destruction is due to the **heat generated by electrical resistance** as current passes through the tissue. *Spark lesion* - A **spark lesion** typically results from low-voltage electricity causing small, localized, superficial burns, often appearing as tiny, scattered, dot-like lesions. - While sparks are involved in electrocution, the image shows a more extensive and deeper burn pattern consistent with direct tissue heating from current flow, not just surface sparks. *Crocodile skin* - **Crocodile skin** (also known as *ichthyosis*) is a dermatological condition characterized by **dry, scaly, and thickened skin**, often with deep prominent creases, resembling crocodile hide. - This is a chronic skin disorder and is unrelated to acute electrical injury. *Scald* - A **scald** is a type of thermal burn caused by hot liquids or steam, leading to **blistering, redness, and pain**. - The appearance in the image is of a dry, desiccated, and often charred lesion, which is distinct from the typical moist and erythematous presentation of a scald.
Question 496: The image shows presence of:
- A. Pond fracture (Correct Answer)
- B. Gutter fracture
- C. Hinge fracture
- D. Fracture à la signature
Explanation: ***Pond fracture*** - The image exhibits a **depressed skull fracture** in a young child, appearing as an indentation or "pond" in the skull, which is characteristic of a pond fracture. - This type of fracture typically occurs in **infants or young children** due to the pliability of their skulls and results from low-velocity blunt trauma. *Fracture à la signature* - A **fracture à la signature** (French: "signature fracture") is a fracture pattern that mirrors the shape and contour of the impacting object. - While this can occur with blunt force trauma, the specific "pond" shape shown in the image—a smooth, depressed indentation characteristic of pediatric skull injuries—is more precisely described as a pond fracture. *Gutter fracture* - A **gutter fracture** is a term sometimes used to describe a depressed fracture where a fragment of bone is driven inward, creating a trough or "gutter." - While it involves depression, the specific "pond" shape in the image, often seen in pediatric skulls, makes "pond fracture" a more precise diagnosis. *Hinge fracture* - A **hinge fracture** is a type of skull fracture that typically extends across the base of the skull, often involving midline structures, resulting in the braincase splitting into two halves, resembling a hinge. - The injury shown in the image is a localized depression on the calvarium, not a widespread basal fracture that divides the skull.
Question 497: The image shows:
- A. Joule burn
- B. Arborescent marks (Correct Answer)
- C. Surface burn
- D. Crocodile burn
Explanation: ***Arborescent marks*** - These are **Lichtenberg figures**, a characteristic branching, fern-like pattern seen on the skin of individuals struck by lightning. - They are cutaneous manifestations of **blood vessel rupture and erythrocyte extravasation** caused by the electrical discharge. *Joule burn* - **Joule burn** is a term for thermal injuries caused by the heat generated from the resistance of tissue to the flow of electrical current, often seen at entry and exit points of an electrical injury. - Unlike arborescent marks, Joule burns present as localized, deep tissue damage, sometimes with charring or necrosis, and do not typically exhibit the branching pattern. *Surface burn* - **Surface burns** are general thermal injuries affecting the skin's outer layers, caused by contact with hot objects, flame, or scalding liquids - They appear as erythema, blistering, or skin loss but do not present with the specific **branching, fern-like pattern** characteristic of electrical injuries. *Crocodile burn* - **Crocodile burn** (or crocodile skin pattern) is a **recognized forensic term** referring to the characteristic splitting and fissuring of heat-exposed skin, resembling crocodile scales. - This pattern results from **heat-induced shrinkage and rupture of the dermis** in bodies exposed to intense fire, and is distinctly different from the branching electrical pattern of arborescent marks.
Question 498: The image shows:
- A. Joule burn
- B. Filigree burn
- C. Surface burn
- D. Crocodile burn (Correct Answer)
Explanation: ***Crocodile burn*** - This image displays a characteristic pattern of **dehydrated skin** that has become **cracked and blackened**, resembling the scales of a crocodile, which is typical of a crocodile burn. - Crocodile burns are often associated with **high-voltage electrical injuries** where the skin is extensively damaged and denatured. *Joule burn* - A Joule burn typically refers to the **internal thermal damage** caused by an electric current flowing through tissues, which may not be immediately visible on the skin's surface in this distinct pattern. - While an electrical injury can cause surface burns, "Joule burn" specifically emphasizes the **heat generation within the body tissues**, not the external appearance shown. *Filigree burn* - A filigree burn, also known as a **Lichtenberg figure**, is a superficial, fern-like skin pattern caused by a **lightning strike**, which is distinct from the extensive, scaly appearance seen here. - These patterns are usually short-lived and represent the path of electrical discharge over the skin, without the widespread tissue destruction evident in the image. *Surface burn* - This is a very general term describing a burn that affects the skin's surface, but it lacks the **specificity** to describe the unique, severe, and distinct desiccation and cracking pattern shown. - The term "surface burn" could apply to many types of burns (e.g., superficial, partial thickness) and does not convey the **characteristic morphology** of a crocodile burn.
Question 499: The following gunshot injury is due to:
- A. Distant shot
- B. Near shot
- C. Close shot
- D. Contact shot (Correct Answer)
Explanation: ***Contact shot*** - A **contact shot** occurs when the muzzle of the weapon is pressed directly against the skin, or very close to it, at the time of discharge, causing powder gases to be injected into the wound. - This typically results in a **gaping wound with irregular margins**, significant tissue destruction, and often a pattern of soot and unburnt powder internally or around the wound due to gas expansion, as seen in the image. *Distant shot* - A **distant shot** is fired from a range where neither powder residues nor muzzle effects reach the skin, leaving only the bullet wound itself. - The entrance wound would typically be a **clean, round, or oval hole** with an abrasion collar, without the extensive soot (fouling) or burning seen here. *Near shot* - A **near shot** (intermediate range) would show **stippling** (tattooing) around the wound, caused by unburnt powder grains impacting the skin. - While there is some dispersed soot on the skin, it is far more concentrated, and there is significant burning and tissue disruption typical of a very close-range discharge, not just stippling. *Close shot* - A **close shot** would produce a pattern of **fouling (soot)** around the entry wound, indicating that gases and microscopic particles from the barrel reached the skin. - However, the degree of tissue disruption, burning, and the deep, irregular nature of the wound in the image are more consistent with gases entering the wound track itself, which is characteristic of a contact shot.
Question 500: The image shows:
- A. Chop wound
- B. Crush laceration
- C. Stab wound
- D. Split laceration (Correct Answer)
Explanation: ***Split laceration*** - **Split lacerations** result from **blunt force trauma** over a bony prominence, causing the skin to tear with irregular, jagged edges as seen in the image. - The wound shows typical features of tissue tearing rather than clean penetration, with **irregular margins** and evidence of stretching forces. *Stab wound* - **Stab wounds** are caused by **pointed objects** that penetrate cleanly, leaving relatively straight edges with minimal surrounding tissue damage. - The irregular, torn appearance in the image is inconsistent with the **clean, linear defect** typically seen in stab wounds. *Chop wound* - **Chop wounds** are produced by **heavy, sharp-edged instruments** like axes, combining features of incised wounds and lacerations with potential bone involvement. - This type would show a much **wider and deeper cut** with possible bone exposure, which is not evident in this case. *Crush laceration* - **Crush lacerations** occur from **compressive forces**, resulting in **stellate or irregular tears** with extensive soft tissue damage and surrounding bruising. - The wound lacks the **extensive tissue destruction**, **devitalized tissue**, and **significant bruising** characteristic of crush injuries.
