NEET-PG 2020 - Forensic Medicine Practice Questions

Q: The onus of proof in civil negligence case against a doctor lies with:

Patient. ***Patient*** - In civil negligence cases, the **plaintiff** (the patient, in this context) bears the **onus of proof**, meaning they must demonstrate that the doctor was negligent. - The patient must establish **duty of care**, **breach of that duty**, **causation** of injury due to the breach, and actual **damages**. *Hospital administration* - The hospital administration might be named as a co-defendant, but the primary burden of proving negligence against the doctor still rests with the patient. - Their liability would usually be **vicarious** (for the actions of employees) or for institutional failures, not for proving individual doctor negligence. *Doctor* - The doctor is the **defendant** in a civil negligence case and is presumed innocent until proven otherwise. - The doctor's role is to **defend** against the allegations, not to prove their own innocence of negligence. *Medical board* - A medical board is a **regulatory body** responsible for licensing and discipline, not for adjudicating civil negligence claims. - They conduct investigations into professional misconduct, but this is separate from the **burden of proof** in a civil lawsuit.

Q: Which of the following test shows yellow needle shaped crystals of spermine picrate?

Barberio's test. ***Barberio's test*** - Barberio's test is a **presumptive test for semen**, which detects the presence of **spermine**. - It yields characteristic **yellow, needle-shaped crystals** of **spermine picrate** upon the addition of picric acid reagent to semen. - This is the **classic finding** that distinguishes this test. *Florence test* - The Florence test is a **presumptive test for seminal fluid**, identifying the presence of **choline** and **spermine**. - It produces characteristic **dark-brown, rhombic or needle-shaped crystals** of **choline periodide** (not spermine picrate) when seminal fluid is tested with Florence's reagent (potassium iodide and iodine). *Teichmann test* - The Teichmann test is a **presumptive test for blood**, specifically detecting the presence of **hemoglobin**. - It forms characteristic **rhombic crystals of hemin (hematin hydrochloride)** when blood is heated with glacial acetic acid and a halide salt. *Takayama's test* - Takayama's test is also a **presumptive test for blood**, identifying **hemoglobin**. - It produces **pink, pyridine hemochromogen crystals** after adding a solution containing pyridine, glucose, and dilute sodium hydroxide to a bloodstain.

Q: In a child who has been raped, the hymen:

May be perforated due to trauma.. ***May be perforated due to trauma.*** - The **hymen is a delicate membrane** that can be easily torn or perforated during sexual assault, especially with forceful penetration. - While hymenal tears are a strong indicator of sexual abuse, a lack of tears does not definitively rule out assault, as the hymen can be **elastic or already have natural openings**. *May be perforated if it were superficial.* - The **depth or superficiality of the hymen** is not the primary determinant of whether it will perforate during rape. - The force and nature of penile or foreign object penetration are more significant factors than its anatomical position for perforation. *Will be intact due to its anatomical position.* - The **hymen's anatomical position near the vaginal opening** makes it vulnerable to physical trauma during sexual assault. - Due to its delicate nature, it is often among the first structures to show signs of injury from forced penetration. *Will be intact because it is deep situated* - The hymen is typically located at the **entrance of the vagina**, not deep within it, making it susceptible to injury during sexual penetration. - Its relative position means it is frequently affected by trauma associated with rape, rather than being protected by depth.
