CFC CFC Forensic Pathology & Cause of Death 2 — Questions and Answers
Question 1: What does the term 'cause of death' refer to in a forensic pathology context?
- The mechanism by which the body ceased to function
- The disease or injury responsible for initiating the fatal sequence of events (Correct answer)
- The manner in which a person died
- The time elapsed since death occurred
Correct answer: The disease or injury responsible for initiating the fatal sequence of events
Cause of death is the specific disease, injury, or condition that set off the sequence of events leading to death, distinct from mechanism or manner.
Question 2: Which type of wound would a forensic consultant expect from a contact gunshot wound to the head?
- A small circular entry with no soot
- Stellate (star-shaped) laceration with soot and stippling (Correct answer)
- Uniform abrasion with no gas effect
- A large irregular exit without soot
Correct answer: Stellate (star-shaped) laceration with soot and stippling
Contact gunshot wounds typically produce stellate lacerations due to gas expansion beneath the skin, along with soot and powder deposits.
Question 3: In forensic pathology, 'stippling' or 'tattooing' on the skin around a wound indicates:
- The wound is an exit wound
- The shot was fired at intermediate range (Correct answer)
- The victim was struck with a blunt object
- Postmortem artifact from decomposition
Correct answer: The shot was fired at intermediate range
Stippling is caused by unburned or partially burned gunpowder particles embedding in the skin, occurring at intermediate range (typically 6 inches to 3–4 feet).
Question 4: A medical examiner classifies a death as 'undetermined' when:
- The victim was a minor
- Available evidence is insufficient to establish manner of death with reasonable certainty (Correct answer)
- The case involves pending litigation
- No autopsy was performed
Correct answer: Available evidence is insufficient to establish manner of death with reasonable certainty
Undetermined manner of death is used when the evidence does not clearly support natural, accidental, suicidal, or homicidal classification.
Question 5: Which tool is most commonly used by forensic pathologists to estimate time of death when the body is in early decomposition stages?
- Carbon dating
- Vitreous humor potassium levels (Correct answer)
- Hair analysis
- Toxicological screening alone
Correct answer: Vitreous humor potassium levels
Vitreous humor (fluid in the eye) potassium levels increase predictably after death and are more resistant to decomposition than blood-based markers.
Question 6: Hypostasis that is bright cherry-red in color is a classic finding associated with which cause of death?
- Drowning
- Carbon monoxide poisoning
- Cyanide poisoning only
- Both carbon monoxide and cyanide poisoning (Correct answer)
Correct answer: Both carbon monoxide and cyanide poisoning
Both carbon monoxide and cyanide poisoning can produce bright cherry-red livor mortis due to the formation of stable oxygenated hemoglobin complexes.
