TNCC Practice Exam with Rationale
What is the key to a high performing trauma team? - anseffective 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: - ansevaluating 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: - ansuncontrolled 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 -
ansreprioritize 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? - ansventilate 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? - ansbase 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
What is the safe pharmacological alternative to opioids for rib fracture pain management in
the anticoagulated patient? - ansintercostal nerve blocks
rationale: continuous intercostal nerve blocks use long-acting anesthetics and can provide
safe and effective pain management for the anticoagulated patient.
In a patient with severe traumatic brain injury, hypocapnia causes: - anscerebral
vasoconstriction
What is the key to a high performing trauma team? - anseffective communication

performance teams and high-quality trauma care
