CFN Wound Assessment and Injury Documentation 2

Question 1

Which type of wound is at HIGHEST risk of appearing smaller than the actual instrument due to tissue elasticity?

Accepted Answer

Stab wound

Answer

Stab wounds appear smaller than the actual blade width because elastic skin tissue retracts after the knife is withdrawn, underestimating the true weapon size.

Question 2

Petechial hemorrhages in the conjunctiva are MOST classically associated with which injury mechanism?

Accepted Answer

Asphyxiation or strangulation

Answer

Petechiae in the conjunctiva result from increased venous pressure during asphyxiation or strangulation causing rupture of tiny capillaries above the compression point.

Question 3

An abrasion with parallel linear striations all oriented in the same direction is MOST consistent with:

Accepted Answer

Sliding or dragging across a surface

Answer

Directional sliding abrasions leave parallel linear marks indicating the direction of movement, providing forensic clues about the victim's body position during injury.

Question 4

When documenting injuries in forensic photography, what series approach is ALWAYS required?

Accepted Answer

Overall, mid-range, and close-up views with a scale ruler

Answer

Forensic photography requires systematic overall orientation, mid-range context, and close-up detail shots with a measuring scale for complete, court-admissible documentation.

Question 5

Which characteristic BEST distinguishes an incised wound from a laceration on visual inspection?

Accepted Answer

Clean, sharp edges vs. torn, irregular edges

Answer

Incised wounds from sharp instruments have clean, well-defined edges, while lacerations from blunt force have irregular, torn edges often with tissue bridging.
