Forensic Medicine flashcards for INI CET

25 of 51 cards from the Forensic Medicine deck — real questions with worked answers.

1. Define Forensic Medicine (Legal Medicine) and state its primary purpose.

   Forensic Medicine is the branch of medicine that applies medical knowledge to the administration of justice. Its purpose is to assist legal/judicial bodies in solving questions of a medical or medico-legal nature (e.g., cause of death, injury interpretation, identity).

2. Differentiate Forensic Medicine, Medical Jurisprudence, and Toxicology.

   Forensic Medicine = application of medical knowledge to law. Medical Jurisprudence = the legal responsibilities/rights of the physician (the law as it applies to medical practice). Toxicology = study of poisons, their effects, detection, and treatment.

3. Who is regarded as the 'Father of Forensic Medicine' and what landmark work is associated with the field's early development?

   Italian physician Paolo Zacchia is regarded as the Father of Legal/Forensic Medicine (Quaestiones Medico-Legales). The Chinese text 'Hsi Yuan Lu' (Washing Away of Wrongs) by Song Ci is the earliest known systematic forensic manual.

4. What is an 'expert witness' and how does the testimony differ from that of a common (lay) witness?

   An expert witness gives opinion evidence based on specialized training/skill (e.g., a doctor on cause of death). A common witness states only facts directly perceived and may not give opinions.

5. State the three core ethical duties of a forensic practitioner when giving evidence.

   Impartiality (neutral, not advocating for either side), confidentiality (within legal limits), and objectivity/truthfulness — basing opinions only on facts and sound science, regardless of who summoned them.

6. In medical negligence, what are the four essential elements ('4 Ds') a plaintiff must prove?

   Duty (doctor owed a duty of care), Dereliction/breach (failure to meet the standard), Damage (harm/injury occurred), and Direct causation (damage was directly caused by the breach).

7. What is the legal standard used to judge whether a doctor was negligent (the standard of care)?

   The Bolam test: a doctor is not negligent if acting in accordance with a practice accepted as proper by a responsible body of medical opinion skilled in that field (modified in India/UK by Bolitho — the opinion must withstand logical analysis).

8. Define 'res ipsa loquitur' and give a medical example.

   'The thing speaks for itself' — negligence is presumed because the injury could not have occurred without negligence and the matter was under the doctor's control. Example: an instrument/sponge left inside the body after surgery.

9. List the essential criteria for a consent to be legally valid.

   It must be free/voluntary, informed (after disclosure of nature, risks, alternatives), given by a person competent (of sound mind and legal age), and specific to the procedure.

10. What is the minimum age of valid consent for a general physical examination versus surgical/anaesthetic procedures in India?

    12 years for consent to a general examination/treatment; 18 years (and of sound mind) for consent to surgical or anaesthetic procedures and other major interventions.

11. Distinguish 'expressed consent' from 'implied consent'.

    Expressed consent is specifically stated (orally or written). Implied consent is inferred from conduct — e.g., a patient extending the arm for a blood pressure check or injection.

12. Under what doctrine may a doctor treat an unconscious emergency patient without consent?

    The doctrine of necessity (implied/emergency consent) — treatment immediately required to save life or prevent serious harm when the patient cannot consent and no authorized person is available.

13. State the four principles of medical ethics (Beauchamp & Childress).

    Autonomy (respect patient's choices), Beneficence (act for the patient's good), Non-maleficence (do no harm), and Justice (fair distribution and treatment).

14. Define the obligation of professional secrecy (medical confidentiality) and name one situation where breach is justified.

    A doctor must not disclose information acquired in professional capacity. Justified disclosure includes: notifiable infectious diseases, court orders, or 'privileged communication' to protect a third party/society from serious harm.

15. What is 'privileged communication' in medical ethics?

    A bona fide statement made by a doctor to a proper authority (in the interest of society or to protect an identifiable individual), where confidentiality may be lawfully breached without liability.

16. What is the difference between somatic (clinical) death and molecular (cellular) death?

    Somatic death = irreversible cessation of the functions of the brain, heart, and lungs (the person is dead). Molecular death = death of individual cells/tissues occurring 1–4 hours later as cellular metabolism ceases.

17. Name the three classical modes of death.

    Coma (failure of the brain/nervous function), Syncope (failure of the heart/circulation), and Asphyxia (failure of respiration/oxygenation).

18. List the order of appearance of the post-mortem changes used to estimate time since death.

    Immediate (cessation of vitals) → early changes: algor mortis (cooling), livor mortis (hypostasis/lividity), rigor mortis (stiffening) → late changes: putrefaction, adipocere, mummification, skeletonization.

19. Describe the typical timing of rigor mortis in a temperate climate.

    Begins 1–2 hours after death, completes (whole body) in about 12 hours, persists ~12 hours, then passes off in ~12 hours (the '12-12-12 rule'). It follows Nysten's law (starts in involuntary muscle, then face/neck → downward).

20. What is the average rate of body cooling (algor mortis) used in estimating time since death?

    Roughly 1.5 °F (≈0.8–1 °C) per hour in the first few hours under average conditions; cooling follows a sigmoid curve (initial plateau, rapid fall, then slowing).

21. Differentiate post-mortem lividity (livor mortis) from a bruise.

    Lividity: appears in dependent areas, vessels intact, no clotting/coagulum, spares pressure points, fades on incision and washes away. Bruise: anywhere, extravasated clotted blood in tissue, swelling, does not wash off on washing.

22. Define cadaveric spasm and state its medico-legal importance.

    Cadaveric spasm is instantaneous stiffening of a group of voluntary muscles at the moment of death without preceding primary flaccidity, occurring in violent/emotional deaths. Importance: it cannot be produced artificially, so a weapon/object gripped in the hand indicates suicide or that the act occurred at death.

23. What is the difference between cause, mechanism, and manner of death?

    Cause = the disease/injury that initiated the lethal sequence (e.g., gunshot wound). Mechanism = the physiological derangement producing death (e.g., exsanguination). Manner = how it arose: natural, accident, suicide, homicide, or undetermined.

24. State the primary objectives of a medico-legal (forensic) autopsy.

    To determine the cause, mode, manner, and time of death; identify the deceased; recover/preserve evidence; and document injuries to assist the criminal justice system. It is ordered by a magistrate/police and does not require relatives' consent.

25. Contrast a clinical (pathological) autopsy with a medico-legal autopsy regarding consent and scope.

    Clinical autopsy: requires consent of relatives, done to determine disease/confirm diagnosis, may be partial. Medico-legal autopsy: by legal authority (no relative consent needed), always complete (all three cavities opened), for legal purposes.
