portion of a person’s body, splits the skin andmay even shatter or tear underlying
structures.

A

Crush wounds

109
Q

sharp pieces of bone penetrate and tear surrounding soft tissue &skin which created an open wound

A

Open fracture

110
Q

Most likely to occur with high energy injuries,

more superficial bones, and among the elderly.

A

Open fracture

111
Q

Characterized by a
slice wound created by a sharp object
which leaves
straight/even edges

A

Cuts/incisions

112
Q

3 basic mechanisms of injury for lacerations

A

Shearing
Tension
Compression

113
Q

Shearing

A

Small amount of force on a small area which typically results in minimal cell injury due to the sharp
instrument

114
