Chapter 29

Question 1

1.  The acute physiologic and structural change that occurs in a patient's body when an external source of energy dissipates faster than the body's ability to sustain and dissipate it is called:
A)  injury.
B)  trauma.
C)  deceleration.
D)  kinematics.

Answer 1

B) trauma

Question 2

2.  The energy stored in an object, such as a bridge pillar, is called \_\_\_\_\_\_\_\_\_\_ energy, and the energy from motion is called \_\_\_\_\_\_\_\_\_\_ energy.
A)  kinetic, potential
B)  barometric, kinetic
C)  potential, kinetic
D)  chemical, potential

Answer 2

C) potential, kinetic

Question 3

3. Knowledge of kinetics can help the paramedic:
   A) predict injury patterns found in a patient.
   B) determine which organs have been injured.
   C) quantify how much blood a patient has lost.
   D) differentiate between medical and trauma patients

Answer 3

A) predict injury patterns found in a patient.

Question 4

4. The primary determinants of the extent of trauma a patient sustains are the:
   A) type of object that strikes a patient and the part of the body that sustains the most impact.
   B) amount of energy in the object and the mechanism by which the object is delivered to the body.
   C) size of the object that strikes the body and any secondary injuries that occur if the patient falls.
   D) physical size of the patient and the part of the body that sustains direct impact from an object.

Answer 4

B) amount of energy in the object and the mechanism by which the object is delivered to the body.

Question 5

5. Which of the following general statements regarding trauma is correct?
   A) Bullet impact is less if the energy in the bullet is applied to a small area.
   B) The position of the patient at the time of the event is considered to be an internal factor.
   C) Blunt trauma is difficult to diagnose by paramedics in the field and is often more lethal than penetrating trauma.
   D) Rapidly applied amounts of energy are better tolerated than a similar amount of energy applied over a longer period.

Answer 5

C) Blunt trauma is difficult to diagnose by paramedics in the field and is often more lethal than penetrating trauma.

Question 6

6.  Which of the following will be of MOST benefit in helping the paramedic predict the type of injuries that a patient experienced?
A)  Index of suspicion
B)  Past medical history
C)  Age of the patient
D)  Mechanism of injury

Answer 6

D) Mechanism of injury

Question 7

7. According to the American College of Surgeons, an injured patient should be transported to a Level I trauma center if his or her:
   A) heart rate is greater than 100 beats/min.
   B) systolic blood pressure is less than 90 mm Hg.
   C) respiratory rate is less than 14 breaths/min.
   D) Glasgow Coma Scale score is less than 15.

Answer 7

B) systolic blood pressure is less than 90 mm Hg.

Question 8

8. Which of the following mechanisms of injury poses the LEAST threat for significant injury?
   A) Rear-end collision with restrained driver
   B) Death of an occupant in the same vehicle
   C) Motorcycle crash at greater than 20 mph
   D) Vehicular intrusion of greater than 12 inches

Answer 8

A) Rear-end collision with restrained driver

Question 9

9. Which of the following injuries would MOST likely require transport to a Level I trauma center?
   A) Two or more proximal long bone fractures
   B) Superficial burns to an entire lower extremity
   C) Lateral neck pain following a motor vehicle crash
   D) Penetrating injury that is distal to the elbow or knee

Answer 9

A) Two or more proximal long bone fractures

Question 10

10.  If the mechanism of injury does not appear to be significant, you should consider transporting an injured patient to a Level I trauma center if he or she:
A)  is older than 45 years of age.
B)  takes any kind of medication.
C)  is emotionally upset or angry.
D)  has a known bleeding disorder.

Answer 10

D) has a known bleeding disorder.
