The wound that poses the greatest risk for serious infection is the
pg 98
puncture.
The injury in which the skin is pulled off a finger, hand, or extremity by farm or industrial
machinery is called a
pg 98
degloving injury.

pg 99
False
Vascular, platelet, and coagulation are phases of the process called
pg 100
