Question 1

The 'rule of nines' is used in death investigation to:

Accepted Answer

Estimate the total body surface area involved in burn injuries

Answer

Estimate time since death from liver temperature decline

Answer

Determine the number of wounds sufficient to cause incapacitation

Answer

Assess decomposition stage on a standardized nine-point scale

Question 2

Which feature most reliably distinguishes an antemortem injury from a postmortem injury?

Accepted Answer

The presence of vital reaction including hemorrhage, inflammation, or early healing

Answer

The overall size and shape of the wound

Answer

The depth of tissue penetration

Answer

The color of the wound margins

Question 3

A 'coup-contrecoup' pattern of brain injury results from:

Accepted Answer

Blunt force impact causing brain injury both at the point of impact and the contralateral side

Answer

Penetrating sharp force trauma directly into the skull

Answer

A gunshot wound with internal bullet ricochet

Answer

Hypoxic-ischemic encephalopathy from asphyxia

Question 4

In a fire-related death investigation, cherry-red coloration of the skin and muscle tissue is most commonly associated with:

Accepted Answer

Carboxyhemoglobin saturation from carbon monoxide poisoning

Answer

Thermal dehydration of tissues

Answer

Postmortem lividity in a prone decedent

Answer

Cyanide toxicity from burning plastics

Question 5

The term 'perimortem' in injury timing means the injury occurred:

Accepted Answer

At or around the time of death, with ambiguous vital reaction

Answer

Long before death, with evidence of healing

Answer

After death during the decomposition process

Answer

During resuscitation by emergency personnel only

Question 6

'Kerf marks' in medicolegal death investigation are most relevant to:

Accepted Answer

Analyzing cut bone surfaces in saw-related dismemberment cases

Answer

Determining firing distance in gunshot cases

Answer

Identifying contact burns from a specific firearm muzzle

Answer

Documenting bite-mark patterns from human or animal dentition

Question 7

At what approximate range from the muzzle does stippling (tattooing) typically appear for a standard handgun?

Accepted Answer

At intermediate range, generally up to approximately 2–4 feet

Answer

Only at true contact range (barrel pressed against skin)

Answer

At long range beyond 10 feet

Answer

Stippling is exclusive to rifle wounds and does not occur with handguns
