pg46

31,500

2

A

pg 46

4x the Kinetic Energy

3
Q

T/F - Wounds from rifle bullets are considered two to four times more lethal than those from

A

True

4
Q

The curved tract a bullet follows during flight is called its

A

pg 47

trajectory.

5
Q

The surface of a projectile that exchanges energy with the object struck is its

A

pg 47

Profile

6
Q

When a rifle bullet hits tissue, normally it will

A

pg 48

tumble 180 degrees then continue.

7
Q

T/F - Although handgun bullets are made of relatively soft lead, their kinetic energy is generally not
sufficient to cause significant deformity.

A

pg 48

True

8
Q

T/F - Civilian hunting ammunition is designed to expand dramatically on impact.

A

pg 49

False

9
Q

Differences between a rifle bullet in contrast to a handgun
bullet?

A

pg 49

It is a heavier projectile

It travels further.

It travels at a greater velocity.

It is more likely to expand.

10
Q

T/F - The shotgun is limited in range and accuracy; however, injuries it inflicts at close range can be
very severe or lethal.

A

pg 50

True

11
Q

Which element of the projectile injury process is related to the actual damage caused as the
bullet contacts tissue?

Direct injury
Pressure wave
Temporary cavity
Permanent cavity
Zone of injury

A

pg 50

Direct injury

12
Q

The formation of subatmospheric pressure behind the bullet as it passes through the body is a
result of

A

pg 51

temporary cavity.

13
Q

The passage of a projectile through the body results in a region where tissues are disrupted and
not functioning normally known as the

A

pg 51

zone of injury.

14
Q

The temporary cavity formed as a high-velocity/high-energy bullet passes may be how large?

A

pg 51

12x the bullet caliber

15
Q

The tissue structure that is very resilient, yet dense, and usually sustains limited damage with
the passage of a projectile is

A

pg 52

connective tissue.

16
Q

The tissue structure that is likely to rupture and spill its contents when struck by a projectile is

A

pg 53

a hollow organ.

17
Q

T/F - Penetrating wounds to the extremities account for about 70 percent of all penetrating wounds
yet account for less than 10 percent of fatalities related to this injury mechanism.

A

pg 53

True

18
Q

The abdominal organ most tolerant to the passage of a projectile is the

A

pg 53

bowel

19
Q

T/F - Because of the pressure-driven dynamics of respiration, any large bullet wound to the chest is
likely to seriously compromise breathing.

A

pg 54

True

20
Q

The body region in which a penetrating wound has the greatest likelihood of drawing air into
the venous system is the

A

pg 54

Neck.

21
Q

Which of the following is NOT associated with an entrance wound?

Tattooing

A small ridge of discoloration around the wound

A blown-outward appearance

Subcutaneous emphysema

Propellant residue on the surrounding tissue

A

pg 55

a blown-outward appearance

22
Q

T/F - The entrance wound is more likely to reflect the actual damaging potential of the projectile
than the exit wound.

A

pg 55

False

23
Q

What information should you gain through the scene size-up, about a GSW if possible?

A

Pg 55

The gun caliber

The angle of the gun to the victim

The type of gun used

Assurance that no other weapons are involved

24
Q

As you care for a patient at a potential crime scene, actions you take to help preserve evidence should include

A

pg 55

disturbing only the items necessary to provide patient care.

25
Q

Frothy blood at a bullet exit or entrance wound suggests a(n)

A

pg 56

tension pneumothorax.

26
Q

An object that weighs twice as much as another object traveling at the same speed has

A

pg 46

twice the kinetic energy.

27
Q

T/F - Wounds from a handgun are two to four times more lethal than those from a rifle.

A

pg 46

False

28
Q

The diameter of a projectile is its

A

pg 47

caliber.

29
Q

What is a characteristic of a handgun bullet in contrast to a rifle bullet?

A

pg 47

It has a blunter shape.

30
Q

T/F - With low-velocity penetrating objects, damage is usually more extensive than just the direct
contact points between the object and human tissue.

A

pg 50

False

31
Q

Which element of the projectile injury process describes the region filled with air and tissue
debris after the bullet has passed?

A

pg 51

Permanent cavity

32
Q

The tissue structures that are very dense and usually sustain significant damage (often breaking
apart) with the passage of a projectile are the

A

pg 53

Bones.

33
Q

The tissue structures that are very resilient and usually sustain the smallest amount of damage
associated with the passage of a projectile are the

A

pg 53

Lungs.

34
Q

The abdominal organ rather tolerant to the passage of a projectile is the

A

pg 53

bowel.

35
Q

T/F - The impact of a bullet with the ribs may induce an explosive energy exchange that injures the
surrounding tissue with numerous bony fragments.

Q

A penetrating wound to the area of the rib margin should be suspected of involving which organs?

A

pg 54

spleen or liver.
