The displacement of tissue away from the path of a projectile, both temporarily and
permanently, is known as:
A. Conization
B. Cavitation
C. Crepitation
D. Contusion - ANS-B. Cavitation
The single most important factor in determining the potential for injury due to energy
exchange is:
A. Mass of the bodies involved
B. Velocity of the bodies involved
C. Density of the tissues involved
D. Surface area of the impact involved - ANS-B. Velocity of the bodies involved
In the management of shock, isotonic crystalloid solutions, such as Ringer's, are
preferred because:
A. The protein molecules in crystalloid solutions act as volume expanders
B. These fluids draw interstitial fluid into the vascular space to enhance volume
C. These solutions will stay in the vascular space longer than water solutions, such as
D5W
D. Their pH enhance oxygen delivery to the tissues - ANS-C. These solutions will stay
in the vascular space longer than water solutions, such as D5W

, During the primary survey and management of a trauma patient, the E in ABCDE
stands for _________?
A. Edema
