The same as other soft-tissue injuries. Direct pressure, stabilization of impaled objects, wrapping or retrieving of avulsed skin.

124
Q

True or False. When dealing with an amputation of the penile shaft, you should apply a tourniquet proximal to the bleeding point.

A

False. Constricting devices are not appropriate for the control of penile bleeding.

125
Q

True or False. Moist, sterile compresses are most appropriate when treating lacerations, abrasions, and avulsions of the female genitalia.

A

True.

126
Q

What are some causes of rectal bleeding?

A

Sexual assault, rectal foreign bodies, hemorrhoids, colitis, or ulcers of the digestive tract.

127
Q

When is it appropriate to examine the genitalia of a victim of sexual assault?

A

If there is obvious bleeding in the area.

128
Q

Why would you want to ask the patient who was a victim of sexual assault if they would be willing to be wrapped in a sterile burn sheet?

A

It can help investigators find any hair, fluid, or fiber from the alleged offender.

129
Q

If a female patient who was a victim of sexual assault insists on urinating, how would you have her do so?

A

Into a sterile urine container (if available), also, have her deposit the toilet paper into a paper bag. Seal and label.

130
Q

What is the difference between a nondisplaced fracture and a displaced fracture?

A

A nondisplaced fracture is a simple crack in the bone that may be difficult to distinguish from a sprain or simple contusion. A displace fracture produces an actual deformity, or distortion, of the limb.

131
Q

What are the specific types of fractures?

A

Comminuted, epiphyseal, greenstick, incomplete, oblique, pathologic, spiral, and transverse.

132
Q

Describe a comminuted fracture.

A

A fracture in which the bone is broken into more than two fragments.

133
Q

Describe an epiphyseal fracture.

A

A fracture that occurs in a growth section of a child’s bone and may result in growth abnormalities.

134
Q

Describe a greenstick fracture.

A

An incomplete fracture that passes only partway through the shaft of a bone but may still cause substantial angulation; occurs in children.

135
Q

Describe an incomplete fracture.

A

A fracture that does not run completely through the bone; a nondisplaced partial crack.

136
Q

Describe an oblique fracture.

A

A fracture in which the bone is broken at an angle across the bone. This is usually the result of a sharp, angled blow to the bone.

137
Q

Describe a pathologic fracture.

A

A fracture of weakened or diseased bone, seen in patients with osteoporosis, infection, or cancer; often produced by minimal force.

138
Q

Describe a spiral fracture.

A

A fracture caused by a twisting or spinning force, causing a long, spiral-shaped break in the bone, this is sometimes the result of abuse in young children.

139
Q

Describe a transverse fracture.

A

A fracture that occurs straight across the bone, this is usually the result of a direct and relatively high-energy blow.

140
Q

What is false motion?

A

Any motion at a point in the limb where there is no joint and therefore motion is not expected to occur.

141
Q

What is a dislocation?

A

A disruption of a joint in which the bone ends are no longer in contact.

142
Q

What is a sprain?

A

When a joint is twisted or stretched beyond its normal range of motion.

143
Q

What is a strain?

A

A stretching or tearing of the muscle and/or tendon, causing pain, swelling, and bruising of the soft tissues in the area.

144
Q

What is an amputation?

A

An injury in which an extremity is completely severed form the body.

145
Q

What are considered Critical Injuries on the musculoskeletal injury grading system?

A

Multiple open fractures of the limbs and suspected pelvic fractures with hemodynamic instability.

146
Q

What should you note before and after splinting?

A

the patient’s neurovascular status.
pulse, sensation, and movement.

147
Q

What are the types of splints?

A

Rigid splints, Formable splints, Pelvic binders.

148
Q

When are some times you would sling and swathe?

A

Any clavicular break, shoulder injury or dislocation. A humeral shaft fracture.

149
Q

How would you treat a dislocated hip?

A

Splint the dislocation in the position of the deformity. Place the patient supine on the backboard. Support the affected limb with pillows and rolled blankets.

150
Q

How is a femoral shaft fracture best stabilized?

A

With a traction splint.
