Disaster Victim Identification Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Disaster Victim Identification. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Disaster Victim Identification Indian Medical PG Question 1: Disputed maternity can be solved by using the following tests, EXCEPT:
- A. Blood grouping
- B. HLA typing
- C. DNA fingerprinting
- D. Precipitin test (Correct Answer)
Disaster Victim Identification Explanation: ***Precipitin test***
- The **precipitin test** is used to determine the origin of a **blood sample**, specifically whether it is **human or animal blood**, by detecting species-specific proteins. It is not used for assessing maternity.
- This test is primarily employed in **forensic serology** to differentiate between blood from different animal species, making it irrelevant for paternity or maternity disputes.
*Blood grouping*
- **Blood grouping** (e.g., ABO and Rh systems) can be used to **exclude paternity or maternity** by comparing the blood types of the child, mother, and alleged father.
- If the child's blood type is incompatible with the alleged parents based on Mendelian inheritance, one or both can be excluded.
*HLA typing*
- **HLA typing** (Human Leukocyte Antigen) is a more powerful genetic marker system than ABO/Rh for determining paternity or maternity.
- It involves analyzing highly polymorphic genes on chromosome 6 that encode cell surface proteins, providing a more definitive means of **inclusion or exclusion**.
*DNA fingerprinting*
- **DNA fingerprinting** (also known as **DNA profiling**) is the **most accurate and widely accepted method** for resolving paternity and maternity disputes.
- It analyzes highly variable regions of DNA unique to each individual, providing a statistically strong basis for **inclusion or exclusion** by comparing genetic profiles.
Disaster Victim Identification Indian Medical PG Question 2: Police inquest is NOT required in:
- A. Suicide
- B. Murder
- C. Death in police custody
- D. Natural death due to disease in elderly person at home (Correct Answer)
Disaster Victim Identification Explanation: ***Natural death due to disease in elderly person at home***
- Police inquest is **NOT required** for natural deaths occurring at home with a known medical condition
- A registered medical practitioner who has been attending the deceased can issue a death certificate
- No suspicion of foul play or unnatural circumstances exists
- This is the only scenario among the options where police involvement is not mandated
*Death in police custody*
- Police inquest is **absolutely required** under **Section 176 CrPC** (mandatory magisterial inquiry)
- Custodial deaths are considered highly sensitive and require thorough investigation
- Ensures accountability and rules out torture, negligence, or human rights violations
- Automatic judicial oversight is mandated by law
*Suicide*
- Police inquest is **required** as suicide is classified as an **unnatural death**
- Investigation needed to confirm manner of death and rule out homicide
- Section 174 CrPC mandates police investigation for all unnatural deaths
- Documentation required for legal and insurance purposes
*Murder*
- Police inquest is **absolutely required** as murder is a **criminal homicide**
- Section 174 CrPC mandates immediate police investigation
- Crime scene examination, evidence collection, and suspect identification are essential
- Forms the basis for criminal prosecution under IPC Section 302
Disaster Victim Identification Indian Medical PG Question 3: Most reliable method to identify putrefied bodies with metallic implants?
- A. Serial number matching (Correct Answer)
- B. X-ray superimposition
- C. Dental comparison
- D. DNA profiling
Disaster Victim Identification Explanation: ***Serial number matching***
- Metallic implants, such as orthopedic prostheses or pacemakers, often carry **unique serial numbers** that can be traced back to the manufacturer and patient records.
- This method is highly reliable even in cases of severe **putrefaction** or fragmentation, as the implant itself is resistant to decomposition.
*X-ray superimposition*
- This method involves superimposing antemortem (before death) and postmortem (after death) X-rays to look for matching anatomical features.
- While useful for bone and tooth identification, it is less reliable for specific identification with metallic implants compared to direct serial number matching, especially if the antemortem X-rays predate the implant.
*Dental comparison*
- **Dental comparison** involves comparing antemortem dental records (X-rays, charts) with postmortem dental findings.
- This method is very effective for identification in general, but it does not directly utilize the metallic implant for identification and thus is not the *most reliable* method when an implant is present.
*DNA profiling*
- **DNA profiling** is highly effective for identification using biological samples, but it relies on obtaining viable DNA.
- In cases of severe putrefaction, obtaining **high-quality, uncontaminated DNA** suitable for profiling can be very challenging or impossible from the remains themselves.
Disaster Victim Identification Indian Medical PG Question 4: Ambulatory patients after a disaster are categorized into what color of triage?
- A. Red
- B. Yellow
- C. Green (Correct Answer)
- D. Black
Disaster Victim Identification Explanation: ***Green***
- **Green tag** is for the walking wounded, meaning those with minor injuries who can move independently and do not require immediate medical attention.
- These patients can often assist with **their own care** or aid others, and their treatment can be delayed.
*Red*
- **Red tag** patients have critical, life-threatening injuries that require immediate intervention to save life or limb.
- This category includes conditions like **severe bleeding**, shock, or airway compromise.
*Yellow*
- **Yellow tag** is assigned to patients with serious injuries that are not immediately life-threatening but require definitive treatment within a few hours.
- Examples include **stable fractures**, moderate burns, or significant but controlled bleeding.
*Black*
- **Black tag** indicates patients who are deceased or have injuries so severe that survival is unlikely even with maximal medical care.
- Resources are diverted from these patients to those with a higher chance of survival, to **maximize overall saved lives**.
Disaster Victim Identification Indian Medical PG Question 5: All are useful in knowing the time since death Except
- A. Postmortem staining
- B. Cooling of the body
- C. Rigor mortis
- D. Postmortem bruising (Correct Answer)
Disaster Victim Identification Explanation: ***Postmortem bruising***
- **Postmortem bruising** is not a reliable indicator for determining the time since death. It represents an injury that occurred **perimortem** or shortly before death, indicating trauma rather than a specific postmortem interval.
- While it can help establish the circumstances of death, it doesn't follow a predictable timeline after death that allows for accurate time estimation.
*Postmortem staining*
- **Postmortem staining**, also known as **livor mortis** or **lividity**, is the settling of blood in dependent parts of the body due to gravity.
- Its presence, distribution, and fixity can provide an estimation of the time of death, appearing within **30 minutes to 2 hours** and becoming fixed after **8-12 hours**.
*Cooling of the body*
- **Cooling of the body**, or **algor mortis**, refers to the decrease in body temperature after death until it equilibrates with the ambient temperature.
- This process is used to estimate time since death, with the rate of cooling influenced by factors like **ambient temperature**, body size, and clothing.
*Rigor mortis*
- **Rigor mortis** is the stiffening of muscles that occurs after death due to chemical changes within the muscle cells.
- It typically begins **2-4 hours** after death, becomes fully established around **8-12 hours**, and resolves after **24-48 hours**, following a predictable sequence of appearance and disappearance.
