1. After death due to Asphyxia left side of the heart is :
- Empty
- Congested
- Cyanosed
- Both (1) and (2)
Answer and Explanation
Answer: (2) Congested
Explanation: In case of death due to asphyxia, the left side of the heart is congested and the right side is empty.
-> REd= Right Side Empty
-> LOC= Left Side Congested
2. Excess of CO2 in blood will:
- Stimulate respiratory center
- Depress respiratory center
- Alternately stimulate and depress the respiratory center
- No effect on respiratory center
Answer and Explanation
Answer: (2) Depress respiratory center
3. The hydrostatic test for live birth depends on changes in the specific gravity of:
- Liver
- Heart
- Lungs
- Kidney
Answer and Explanation
Answer: (3) Lungs
Explanation: A hydrostatic test is a test for the specific gravity of the lungs which makes the lungs float. This test is also called the floatation test or Raygat’s test. The lungs that have filled air have a specific gravity lesser than the collapsed lungs (child not breathing after birth) that’s why they float.
4. Match the following:
List-I | List-II |
(a) Constriction of the neck by the bodyweight through the ligature | (i) Drowning |
(b) Constriction of the neck by hand | (ii) Hanging |
(c) Submerger of face in the water | (iii) Throttling |
(d) Inhalation of poisonous gasses | (iv) Poisoning |
(a) | (b) | (c) | (d) | |
1. | (iii) | (ii) | (i) | (iv) |
2. | (ii) | (iii) | (i) | (iv) |
3. | (iii) | (ii) | (iv) | (i) |
4. | (iv) | (i) | (ii) | (iii) |
Answer and Explanation
Answer: (2) (ii), (iii), (i), (iv)
Explanation:
-> Throttling: hyoid bone is the most diagnostic finding of throttling.
-> Hanging: Dribbling of saliva
5. Presence of froth and weeds in airways is suggestive of
- Post-mortem drowning
- Ante-mortem drowning
- Head injury
- None of the above
Answer and Explanation
Answer: (2) Ante-mortem drowning
Explanation: Froth and weeds in the airways are a clear sign of antemortem drowning.
6. The ligature mark in asphyxial death is a
- Split laceration
- Grazed abrasion
- Patterned abrasion
- Stretch laceration
Answer and Explanation
Answer: (3) Patterned abrasion
Explanation: Patterned abrasion is a disruption of the continuity of the most superficial layers of skin due to the action of a perpendicular force that reproduces the pattern of the object causing it.
7. Assertion (A) : Bloodless dissection of neck structures is recommended in deaths due to strangulation.
Reason (R): It allows identifying and excluding post-mortem artifacts.
- (A) is correct but (R) is wrong
- Both (A) and (R) are correct
- (A) is incorrect but (R) is correct
- (A) and (R) are incorrect
Answer and Explanation
Answer: (2) Both (A) and (R) are correct
8. Match the following:
List-I | List-II |
(a) Asphyxial death caused by suspension of the body by a ligature encircling the neck | (i) Drowning |
(b) Asphyxial death caused by constriction of the neck by a ligature without suspending the body | (ii) Smothering |
(c) Asphyxial death caused due to aspiration of fluid into air-passage | (iii) Strangulation |
(d) Asphyxial death caused by closing the external respiratory orifices | (iv) Hanging |
(a) | (b) | (c) | (d) | |
1. | (iv) | (iii) | (ii) | (i) |
2. | (i) | (iii) | (ii) | (iv) |
3. | (iv) | (iii) | (i) | (ii) |
4. | (iv) | (i) | (ii) | (iii) |
Answer and Explanation
Answer: (3) (iv), (iii), (i), (ii)
9. In which asphyxial death is the tongue protruded?
- Burking
- Traumatic asphyxia
- Choking
- None of the above
Answer and Explanation
Answer: (4) None of the above
Explanation:
-> Protruded tongue is generally seen in death by hanging.
-> In very rare cases protruded tongue is also seen in advanced putrefaction cases due to gas formation.
10. In which of the following asphyxial deaths, there is no pressure over the neck structures?
- Hanging
- Ligature strangulation
- Gagging
- Throttling
Answer and Explanation
Answer: (3) Gagging
Explanation: Gagging is a form of asphyxia where a gag (clothes or paper) is pushed deep into the mouth which eventually blocks the pharynx.
11. Match the following
List-I (Type of asphyxia) | List-II (Method/Mechanism) |
(a) Burking | (i) Seed getting inside Trachea |
(b) Cafe’ coronary | (ii) Pushing of cloth in mouth |
(c) Gagging | (iii) Traumatic asphyxia + smothering |
(d) Choking | (iv) Sudden death due to impaction of food in windpipe |
(a) | (b) | (c) | (d) | |
1. | (i) | (iii) | (ii) | (iv) |
2. | (iii) | (iv) | (ii) | (i) |

4. | (iv) | (iii) | (ii) | (i) |
Answer and Explanation
Answer: (2) (iii), (iv), (ii), (i)
12. Tardieu’s spots are most commonly associated with
- Asphyxia
- Still-borns
- Death due to firearms
- Putrefaction
Answer and Explanation
Answer: (1) Asphyxia
Explanation: Tardius’s spots are the round purple to red pinhead-sized spots found over the skin from the rapture of the capillary.
13. Fatal hypoxia occurs when oxygen saturation of arterial blood drops to
- 90 mm Hg
- 70 mm Hg
- 20 mm Hg
- 2 mm Hg
Answer and Explanation
Answer: (2) 70 mmHg
Explanation: -> Normal arterial oxygen is approximately 75 to 100 millimeters of mercury (mm Hg).
-> Fatal hypoxia occurs when oxygen saturation of arterial blood drops under 60 mm Hg (by Mayoclinic.org)
14. Compression of the body within a narrow space resulting in asphyxia is known as
- Choking
- Bansdola
- Burking
- Wedging
Answer and Explanation
Answer: (4) Wedging
Explanation:
-> Choking: an obstruction within the air passages by a foreign object.
-> Bansdola: A type of strangulation by sticks.
-> Burking: Homicidal asphyxia where both smothering and traumatic asphyxia is used to kill a person.
