and manner of death, which is ultimately certified by a physician.
QUESTION 3: Which of the following is NOT a manner of death?
A. Natural
B. Accident
C. Homicide

CORRECT ANSWER: D. Cardiac arrest

QUESTION 4: What is the difference between cause of death and mechanism
of death?
A. They are the same thing
B. Cause of death is the injury or disease; mechanism is the physiological
derangement that results in death
C. Mechanism of death is the disease; cause of death is the physiological response
,D. Cause of death is always cardiac arrest
E. Mechanism of death is determined by the investigator, not the pathologist
CORRECT ANSWER: B. Cause of death is the injury or disease; mechanism is
the physiological derangement that results in death
EXPERT RATIONALE: The cause of death is the underlying condition (e.g., gunshot
wound), while the mechanism is the physiological process by which that condition
caused death (e.g., exsanguination or cardiac arrest).
QUESTION 5: Rigor mortis typically begins within how many hours after
death?
A. Immediately upon death
B. 24–36 hours after death
C. 2–6 hours after death
D. 12 hours after death
E. 48 hours after death
CORRECT ANSWER: C. 2–6 hours after death
EXPERT RATIONALE: Rigor mortis generally begins 2–6 hours after death, reaches full
rigidity around 12 hours, and begins to resolve at approximately 24–48 hours,
depending on environmental conditions.
QUESTION 6: Livor mortis is best described as:
A. The stiffening of muscles after death
B. The decomposition of soft tissue
C. The pooling of blood in dependent body parts after death
D. The cooling of the body after death
E. The drying of exposed tissue after death
, CORRECT ANSWER: C. The pooling of blood in dependent body parts after
death
EXPERT RATIONALE: Livor mortis (lividity) occurs when blood settles by gravity into
dependent areas of the body after circulation ceases, causing purplish-red discoloration.
QUESTION 7: Fixed livor mortis indicates:
A. The body has not been moved since death
B. The body was moved after lividity became fixed, typically after 8–12 hours
C. The individual died from poisoning
D. The cause of death is undetermined
E. Decomposition has begun
CORRECT ANSWER: B. The body was moved after lividity became fixed,
typically after 8–12 hours
EXPERT RATIONALE: If livor mortis is fixed and its location is inconsistent with the
body's current position, it suggests the body was repositioned after lividity set, which is
forensically significant.
QUESTION 8: Algor mortis refers to:
A. Skin discoloration after death
B. Muscle stiffness following death
C. The postmortem cooling of the body
D. Internal decomposition gases
E. Insect activity on the body
CORRECT ANSWER: C. The postmortem cooling of the body
