TNCC Practice Exam with Rationale
What is the key to a high performing trauma team? - ✔✔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: -
✔✔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: - ✔✔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
the across-the-room observation step in the initial assessment provides the opportunity to -
✔✔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?
- ✔✔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? - ✔✔base deficit
