Abruptio placentae
Which of the following best describes why the occupants of a vehicle moving at 50 miles per hour will be injured when the vehicle strikes a tree but not when it brakes to a stop?
The energy gradually dissipates as heat due to the friction of braking, rather than transferring to the vehicle and its occupants.
In frontal impact collisions which pathway of patient travel results in higher mortality?
Up-and-over

Compression injury of the cervical spine
Which of the following factors is NOT a consideration in the severity of injury related to falls?
Wind resistance
Which of the following is TRUE of motorcycle collisions?
Frontal impact can result in intraabdominal, pelvic, and femur injuries.
In which of the following types of impact should you have a higher index of suspicion because the degree of injury may be greater than the damage alone indicates?
Lateral
Which of the following best defines the term energy?
the capacity to do work
Which of the following contributes to a greater degree of injury than anticipated from vehicle damage alone in a lateral-impact motor vehicle collision?
Lack of a crumple zone
Which of the following injuries is NOT commonly related to snowmobiling?
Drowning
Which of the following is the most important priority when caring for a patient with a shallow-water diving injury?
Maintaining cervical spine stabilization while opening the airway
Which of the following impacts the severity of injury sustained in a motor vehicle collision?
Gross Vehicle weight, rate of acceleration or deceleration, vehicle speed; ALL OF THE ABOVE
Which of the following is NOT a type of collision that must be considered when analyzing a motor vehicle collision?
A hubcap flies off and strikes a tree
Which of the following best describes what happens to the kinetic energy of a vehicle traveling at 65 miles per hour when it collides into a concrete barrier wall?
The body of the vehicle and its occupants absorb the energy.
Which two of the following factors proportionately affect the kinetic energy of a bullet fired from a gun?
Velocity and mass
Which of the following injuries is associated with the pressure wave produced by a blast?
Pneumothorax
Axial loading is most likely to occur in which type of impact?
Frontal with an up-and-over pathway
Which of the following “paper bag syndrome” injuries may occur due to sudden compression of the thorax or abdomen?
Pneumothorax and diaphragmatic rupture
Which of the following statements about lateral impact collisions is TRUE?
The degree of injury may be greater than the damage alone would indicate
Which of the following mechanisms is most consistent with fractured vertebrae from a rapid lateral twisting motion?
Lateral-impact motor vehicle collision
Frontal impacts in which the patient takes a “down-and-under” pathway typically result in which of the following injury patterns?
Hip and femur fractures
You are dispatched to a building collapse with an entrapped patient who will require a lengthy extrication. Which of the following medications should you consider for this patient while awaiting extrication?
Sodium bicarbonate
Which of the following is TRUE of the injuries sustained by the elderly due to falls?
Less significant falls may cause fractures.
Which of the following is NOT one of the major types of recreational vehicles involved in crashes?
Go-carts
Which of the following traumas contributes most significantly to motor vehicle collision mortality?
Head
In a motor vehicle collision, when the driver’s chest strikes the steering wheel, what produces injury next?
The heart continues its forward motion until it strikes the chest wall.
When inspecting the interior of a vehicle involved in a frontal collision, you note that the dash panel beneath the steering wheel is broken. Which of the following injuries might this indicate?
Fracture of the acetabulum, femur fracture, knee injury; ALL OF THE ABOVE
Which of the following injuries is associated with the tertiary phase of a blast?
Crush injuries
Which of the following statements about the impact of motorcycle helmet usage is TRUE?
Helmet use neither increases nor decreases the incidence of cervical spine injury.
Which of the following mechanisms in a motor vehicle collision would most likely result in a tear of the liver at the ligamentum teres?
Sudden Deceleration
Which of the following statements is NOT true of occupant ejection in motor vehicle collisions?
Ejection has not been reported with lateral-impact collisions.
Which of the following may result from aggressive ventilation of the blast patient?
Emboli
A vehicle is struck in its right front as it passes through an intersection, resulting in an oblique impact. Which of the passengers is subjected to the greatest acceleration forces?
The left-rear passenger
You have responded to a soccer field on which two 13-year-olds have collided during a game. Which of the following findings in either patient requires ambulance transport for further evaluation in the emergency department?
Weakness in the upper extremities
Which type of motor vehicle collision is most common in rural areas?
