The general impression step in the initial assessment provides the opportunity to do which of the
following? - ANSWER✔ A: The general impression is formed to identify uncontrolled external
hemorrhage, not internal hemorrhage. B: The general impression is formed to identify uncontrolled
external hemorrhage. It does not affect triage. C: The general impression is formed at the beginning of
the primary survey to rapidly assess the need to reprioritize circulation before airway or breathing. This
is done if uncontrolled external hemorrhage is identified. D: The trauma team is activated before arrival
of the patient.
Ans: C
What technique is most appropriate when obtaining a history from a patient who has experienced a
sexual assault? - ANSWER✔ Therapeutic communication techniques such as active listening decrease
unintentional distress during the interaction.
Ans: Apply Active Listening
Understanding the kinematic concepts associated with mechanism of injury and energy transfer can
initially assist the trauma care provider in which of the following? - ANSWER✔ A: Mechanism of
injury and energy transfer can assist the provider in anticipating and evaluating the types of injuries that
may be present and their severity.
B: Various aspects of the history of the traumatic event may help determine the need for law
enforcement, but the mechanism of injury and energy transfer assist the provider in anticipating and
evaluating the types of injuries that may be present and their severity.C: Mechanism of injury and
energy transfer can assist the provider in anticipating and evaluating the types of injuries that may be
present and their severity, which, in turn, help establish the need for laboratory tests.
D: Mechanism of injury and energy transfer can assist the provider in anticipating and evaluating the
types of injuries that may be present and their severity, which, in turn, help establish the need for
surgical procedures.
Ans: A
, A patient involved in a MVC has sustained a fracture to the second rib of the anterior left chest. Which
concurrent injury is most commonly associated with this fracture? - ANSWER✔ A: Blunt cardiac injury
is most often associated with sternal fractures.B: First and second rib fractures are most commonly
associated with great vessel, head and spinal cord, and brachial plexus injuries.C: Pneumothorax is most
commonly associated with sternal fractures, multiple rib fractures, or flail chest.D: Hemothorax is most
commonly associated with flail chest of multiple rib fractures.
Ans: B
What is the appropriate technique for palpating the pelvis for stability? - ANSWER✔ A: To assess for
pelvic instability, gentle pressure is applied over the iliac crests, downward and medially, not laterally.B:
To assess for pelvic instability, gentle pressure is applied over the iliac crests, downward and medially.C:
To assess for pelvic instability gentle, not firm, pressure is applied over the iliac crests, downward and
medially, not laterally.D: To assess for pelvic instability gentle, not firm, pressure is applied over the iliac
crests, downward and medially.
Ans: B
Following a bomb explosion, fragmentation injuries from the bomb or objects in the environment are
examples of which phase of injury? - ANSWER✔ A: The primary phase of a blast results from impact
of the pressurization wave on body surfaces. Injuries include blast lung, tympanic membrane rupture,
abdominal hemorrhage, globe rupture, and mild traumatic brain injury.B: The secondary phase of a blast
results from flying debris, projectiles, and bomb fragments causing lacerations or penetrating injuries.C:
The tertiary phase of a blast results from individuals being thrown by the blast and impacting walls,
ground, or any hard object.D: The quaternary phase of a blast results from any explosion-related illness
or injury including hyperglycemia, hypertension, angina, asthma, COPD, or sepsis.
Ans: B Secondary
Treatment for frostbite can include which of the following interventions? - ANSWER✔ A: Warming for
frostbite is done gently, over 15 to 30 minutes.B: Friction, even gentle friction, is avoided to prevent
tissue damage.C: With frostbite, thrombus formation is a risk. Tissue plasminogen activator, a
thrombolytic medication, has been effective in maintaining perfusion and decreasing the need for
amputation when administered within 24 hours of rewarming.D: Large blisters, whether clear or
hemorrhagic, that can affect movement should be drained. Smaller blisters should be left intact.
