Answers & Detailed Rationales
Question 1: Which term refers to the specific physiological
derangement produced by a cause of death, such as exsanguination
or cardiac arrhythmia?
A. Manner of death
B. Cause of death
C. Mechanism of death
D. Mode of death
CORRECT ANSWER: C. Mechanism of death
Rationale: Mechanism of death describes the physiological or biochemical
process that directly results in the cessation of life. Cause of death is the
disease or injury that initiates the fatal sequence, while manner of death
classifies the circumstances (natural, accident, suicide, homicide,
undetermined) .
Question 2: What is the investigator's paramount priority upon first
arriving at a death scene?
A. Photographing the body in situ
B. Ensuring scene safety for all personnel
C. Locating and interviewing witnesses
D. Documenting environmental conditions
CORRECT ANSWER: B. Ensuring scene safety for all personnel
Rationale: Scene safety is the universally paramount initial consideration.
Investigators must confirm the absence of hazards (structural, chemical,
electrical, or hostile) before proceeding with any investigative activities to
prevent injury and preserve scene integrity .
,Question 3: Which postmortem change is characterized by the
gravitational settling of blood in dependent body parts, causing
purplish-red discoloration?
A. Rigor mortis
B. Algor mortis
C. Livor mortis
D. Decomposition
CORRECT ANSWER: C. Livor mortis
Rationale: Livor mortis (lividity) is the settling of blood in dependent
capillaries after circulation ceases. It begins within 20 minutes to 2 hours
and becomes fixed in 8-12 hours, providing information about body
position after death .
Question 4: The ABMDI was established to promote the highest
standards of practice for medicolegal death investigators based
primarily on which foundational document?
A. The FBI Uniform Crime Reporting Handbook
B. Death Investigation: A Guide for the Scene Investigator
C. The Federal Rules of Evidence
D. The Occupational Safety and Health Act
CORRECT ANSWER: B. Death Investigation: A Guide for the Scene
Investigator
Rationale: The ABMDI certifies individuals based on knowledge and skills
set forth in the National Institute of Justice publication Death Investigation:
A Guide for the Scene Investigator (1999, updated 2011), which identified
29 essential tasks for conducting proper medicolegal death investigations .
Question 5: In the context of a medicolegal death investigation,
what does the term "jurisdiction" primarily refer to?
A. The geographic area where the death occurred
B. The legal authority to investigate a death
C. The court system overseeing the case
D. The law enforcement agency responding to the scene
CORRECT ANSWER: B. The legal authority to investigate a death
, Rationale: Jurisdiction in medicolegal death investigation refers to the
statutory authority of the coroner or medical examiner to investigate
certain categories of death (e.g., suspicious, violent, unexpected). This
authority is triggered by specific criteria, not merely geographic location .
Question 6: Which of the following deaths would most likely fall
under medicolegal jurisdiction?
A. An 82-year-old with documented terminal cancer who dies at home
under hospice care with a physician willing to sign the death certificate
B. A 45-year-old with no known medical history found unresponsive at
home with no physician willing to certify the death
C. A 30-year-old who dies during a scheduled surgical procedure with
documented complications and an attending surgeon
D. A 60-year-old with advanced dementia who dies in a nursing facility with
expected natural causes
CORRECT ANSWER: B. A 45-year-old with no known medical
history found unresponsive at home with no physician willing to
certify the death
Rationale: Deaths that are unexplained, unexpected, or where no qualified
physician is willing or able to certify the cause of death typically fall under
medicolegal jurisdiction. The other options describe expected natural
deaths with appropriate medical certification .
Question 7: Which of the following best defines the term "manner
of death"?
A. The specific physiological process that directly resulted in cessation of
life
B. The disease or injury that initiated the sequence of events leading to
death
C. The classification of death as natural, accident, suicide, homicide, or
undetermined
D. The time elapsed between the onset of fatal injury and biological death
CORRECT ANSWER: C. The classification of death as natural,
accident, suicide, homicide, or undetermined
Rationale: Manner of death is a medicolegal determination that categorizes
the circumstances surrounding death into one of five classifications: natural,
accident, suicide, homicide, or undetermined .
