TNCC Practice Exam with Rationale
What is the key to a high performing trauma team? -
correct answer ✅effective communication
rationale: skilled communication, cooperation, and coordination are
the cornerstones of high-performance teams and high-quality
trauma care
When obtaining a history for an injured patient, understanding the
kinematic concepts associated with the mechanism of injury and
energy transfer can initially assist the trauma provider in: -
correct answer ✅evaluating and anticipating the types of injuries
that may be present
rationale: mechanism of injury and energy transfer can assist the
provider in evaluating and anticipating damage
the major preventable cause of death in the trauma patient is: -
correct answer ✅uncontrolled hemorrhage
rationale: uncontrolled hemorrhage is the major cause of
preventable death after injury, so assessment to identify
uncontrolled hemorrhage is key to the initial assessment process
, TNCC Practice Exam with Rationale
the across-the-room observation step in the initial assessment
provides the opportunity to -
correct answer ✅reprioritize circulation before airway or breathing
rationale: the across-the-room observation is done 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.
Which of the following accurately describes ventilation prinicples
associated with a bag-mask device? -
correct answer ✅ventilate at a rate of 10-12 breaths/minute
rationale: if ventilation is ineffective, assist ventilation at 10-12
breaths/minute or one every 5-6 seconds
Which of the following is the best measure of the adequacy of
cellular perfusion and helps to predict the outcome of
resuscitation? -
correct answer ✅base deficit
rationale: base deficit serves as an endpoint measurement of the
adequacy of cellular perfusion and when used in conjunction with
serum lactate helps predict the success of resuciation
