1. According to Dupuytren’s classification, blister formation is graded as
- I degree
- II degree
- III degree
- IV degree
Answer and Explanation
Answer: (2) II degree
Explanation: Dupuytren’s classification defines the severity of the burn. In total. There are six degrees of severity.
-> 1st-degree burn: erythema (redness of the skin)
-> 2nd degree burn: Blister
-> 3rd degree burn: the destruction of the epidermis.
-> 4th degree burn: Destruction of the whole thickness of the skin.
-> 5th-degree burn: Destruction of Muscles
-> 6th degree burn: destruction of bone, nerves, trunk, etc.
2. Which finding in the body is suggestive of antemortem burns?
- 100% burns
- Soot in airways
- Flexion in joints
- None of the above
Answer and Explanation
Answer: (2) Soot in airways
3. Which of the following is not a feature of antemortem burns?
- Cherry red color of blood
- Soot in the airways
- Blisters over skin
- Inflammation of skin
Answer and Explanation
Answer: (3) Blisters over skin
Explanation: Some common characteristics of antemortem burns are
-> Soot in the upper respiratory tract
-> Inflammation, healing, and repair of skin
-> Cherry red color (Carboxyhemoglobin) of blood
4. The injury sustained by the skin due to an alternating current is called
- Brush burn
- Filigree burn
- Joule burn
- Arborescent mark
Answer and Explanation
Answer: (3) Joule burn
Explanation:
-> Joule Burns: They are round, oval or irregular, chalky white, shallow, centrally collapsed blisters that have a raised border and are especially present on the palmar region of hands. They are caused because of the heat generated in the body from electric current interaction.
-> Filigree burns: They are caused by lightning strikes that are characterized by the irregular, multiple arborescent marking resembling the branches of the tree and usually present in over the shoulder area. Other names of filigree burns are Lichtenberg’s flowers and Arborescent burns.
5. Acro Reaction test helps to identify a:
- Entry wound of filigree burn
- Exit wound of filigree burn
- Entry wound of joule burn
- Exit wound of joule burn
Answer and Explanation
Answer: (3) Entry wound of joule burn
Explanation: Acro Reaction test is a micro-chemical test for the detection of entry wounds of joule burn based on the deposition of metal particles at the site of entry of electric current.
6. Suspended animation may be seen in which of the following types of deaths?
(a) Burns (b) Drowning (c) Hanging (d) Electrocution
- (a) and (b) are correct
- (b) and (c) are correct
- (a) and (d) are correct
- (b) and (d) are correct

These are some of the common reasons for the suspended animation are Hypothermia, Barbiturates and Opiates, Newborns, Drowning, Electrocution, Heatstroke, Cholera, Postanesthesia, Cerebral concussion or insanity.
7. As per “Rule of Nine”, the surface area of the body involved for the trunk is:
- 9%
- 18%
- 27%
- 36%
Answer and Explanation
Answer: (4) 36%
Explanation: To depict the total body surface area (TBSA) of body burn, Wallace Rule of Nines is used.
-> Each upper limb: 9% of TBSA (total 18%)
-> Each front and back of the lower limb: 9% of TBSA (total 18%)
-> Each side of upper trunk (chest): 9% of TBSA (total 18%)
-> Each side of lower Trunk (abdomen): 9% of TBSA (total 18%) [total trunk : 36% of TBSA]
-> Head and neck: 9% of TBSA
-> Perineum: 1% of TBSA
