The displacement of tissue away from the path of a projectile, both temporarily
and permanently, is known as:
Cavitation
The single most important factor in determining the potential for injury due to
energy exchange is:
Velocity of the bodies involved
In the management of shock, isotonic crystalloid solutions, such as Ringer's, are
preferred because:
These solutions will stay in the vascular space longer than water solutions, such as
D5W
With respect to the distance of a fall, which of the following is a guideline for
determining a critical fall?
3 times the height of the patient
The phase of an explosion, or blast, in which hollow organs are squeezed and
may rupture is called the __________ phase.
Primary phase
During the primary survey and management of a trauma patient, the E in ABCDE
stands for _________?
Expose/Environment
The time in which surgical intervention can make a difference in patient outcome
is the __________?
Golden period (hour)
In the absence of extenuating circumstances, the maximum amount of time it
should take to identify and manage immediate threats to life, prepare the patient
for transport and begin transport is _________?
10 minutes
In which of the following situations is the use of a short spinal immobilization
device indicated?
None of the above
Your patient is a 32 year old man, restrained driver of a vehicle that has been
involved in a frontal impact with a concrete bridge abutment. The patient is
awake, but has difficulty answering questions due to shortness of breath. His
ventilatory rate is 30 per minute. Of the following choices, when is the first time
the patient's breath sounds should be checked?
, Prior to being removed from the vehicle
Which of the following represents adequate spontaneous ventilation in an adult?
Tidal volume 600 mL, ventilatory rate 12/minute
Which of the following is 100% accurate in verifying endotracheal tube
placement?
None of the above
When utilizing percutaneous transtracheal ventilation, the correct ration of lung
inflation to lung inflation time, in seconds, is:
1:4
Which of the following is a possible complication of using a manually triggered
oxygen powered device for ventilation?
All of the above
Which of the following procedures is considered an essential airway
Insertion of an oropharyngeal airway
Pericardial tamponade is most likely to occur in which of the following
situations?
Stab wound to the chest
Which of the following is the preferred site for needle decompression of a tension
pneumothorax?
2nd intercostal space, midclavicular line, just over top of the 3rd rib
Which of the following is the mechanism by which pulmonary contusion
interferes with oxygenation?
Blood and fluid in the alveoli and interstitial spaces of the lung
Your patient is a 55 year old male who was struck in the right side of the chest
with a piece of steel pipe. He presents with uncooperative behavior, his skin is
pale and moist, the ventilatory rate is 32, there is a weak radial pulse of 112, and
breath sounds are decreased on the right side. The trachea is midline and jugular
veins are flat while the patient is supine. There is isolated crepitus over the 4th
and 5th ribs in the midaxillary line on the patient's right side. Based on the
mechanism of injury and the assessment findings, which of the following is the
most likely cause of the patient's signs and symptoms?
Hemothorax
Deterioration of ventilation and oxygenation after inflation of a PASG in a patient
who has sustained a high-pressure compression injury of the abdomen, such as
