EXAM QUESTIONS
QUESTION 1
Passive Stains
CORRECT ANSWER
Drops, Flows, and Pools, results from gravity acting
RATIONALE: This answer is correct because it accurately describes the effects of gravity on liquids, resulting in the
formation of droplets, flows, and pools. The concept of passive stains, referring to the static patterns left behind by
liquids after they have moved or settled, is a direct consequence of these gravitational effects on liquids.
QUESTION 2
Transfer Stains
CORRECT ANSWER
object coming in contact with existing blood stains and leaving wipes, smears, or pattern transfers
Trusted by thousands of students and professionals worldwide Page 1 of 15
, RATIONALE: When an object comes into contact with existing blood stains, it can transfer those stains through wipes,
smears, or pattern transfers, which is a characteristic of transfer stains. This phenomenon occurs because the object
picks up the blood molecules from the original stain and deposits them elsewhere, resulting in a new set of stains that
resemble the original pattern.
QUESTION 3
Impact Stains
CORRECT ANSWER
blood projecting through air and usually seen as splatters. (May also include gushes, splashes, and arterial
spurts.)
RATIONALE: Impact stains are characterized by the sudden, forceful transfer of a substance, in this case, blood, from
one surface to another, resulting in splatters, gushes, or spurts. This type of stain is distinct from other types of stains,
such as those caused by gravity or diffusion, due to its dynamic and forceful nature.
QUESTION 4
Gunshot Splatter
CORRECT ANSWER
Includes forward splatter from exit wound and back splatter from entrance wound. Typically: Forward is a
fine mist and the back is larger, fewer drops.
RATIONALE: When a bullet exits a body, it creates forward splatter due to the rapid expansion of gases and the
disintegration of tissue, producing a fine mist. Conversely, the entrance wound creates back splatter as the bullet and
surrounding material are propelled backward, resulting in a larger, fewer-drop splatter pattern.
QUESTION 5
Cast-Off
CORRECT ANSWER
Results when an object sung in arc flings blood onto nearby surfaces. Tail points in direction of motion and
the number of arcs can show minimum number of blows.
RATIONALE: The correct answer refers to the characteristics of a boomerang when it is cast off, specifically its curved
motion and the relationship between its flight path and the number of arcs it makes. The description accurately captures
the physical properties of a boomerang's cast-off motion, which involves a spinning, arcing trajectory that can deposit
objects, such as blood, on nearby surfaces.
QUESTION 6
Arterial Spray
CORRECT ANSWER
Spurt of blood when a major artery is severed with new pattern created each time the heart pumps
