PHTLS Post Test 9th 2022; 100% Verified
1. The displacement of tissue away from the path of a projectile, both tem-
porarily and permanently, is known as:
: Cavitation
2. The single most important factor in determining the potential for injury due
to energy exchange is:: Velocity of the bodies involved
3. 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
4. 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
5. The phase of an explosion, or blast, in which hollow organs are squeezed
and may rupture is called the phase.
: Primary phase
6. During the primary survey and management of a trauma patient, the E in
ABCDE stands for ?
: Expose/Environment
7. The time in which surgical intervention can make a difference in patient
outcome is the ?
: Golden period (hour)
8. 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
9. In which of the following situations is the use of a short spinal immobiliza-
tion device indicated?
: None of the above
10. 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
1/8
, PHTLS Post Test 9th 2022; 100% Verified
11. Which of the following represents adequate spontaneous ventilation in
an adult?
: Tidal volume 600 mL, ventilatory rate 12/minute
12. Which of the following is 100% accurate in verifying endotracheal tube
placement?
: None of the above
13. When utilizing percutaneous transtracheal ventilation, the correct ration
of lung inflation to lung inflation time, in seconds, is:
: 1:4
14. Which of the following is a possible complication of using a manually
triggered oxygen powered device for ventilation?
: All of the above
15. Which of the following procedures is considered an essential airway: In-
sertion of an oropharyngeal airway
16. Pericardial tamponade is most likely to occur in which of the following
situations?
: Stab wound to the chest
17. 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
18. 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
19. 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
