TNCC PRACTICE EXAM QUESTIONS
AND ANSWERS (GRADED A+)
what is the key to high performance trauma team? - ANSWER-effective communication
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 what? - ANSWER-evaluating and anticipating the types of injury that
may be present
MOI and energy transfer can assist the provider in evaluating and anticipating damage
what is the major preventable cause of death in the trauma patient? - ANSWER-
uncontrolled hemorrhage
uncontrolled hemorrhage is the major cause of preventable death after injury so
assessment to identify uncontrolled hemorrhage is key to the initial assessment process
across the room observation in initial assessment provides the opportunity to do what? -
ANSWER-reprioritise circulation before airway and breathing
across the room observation is done before the primary survey to rapidly assess the
need to reprioritise circulation before airway or breathing if there is uncontrolled external
bleeding
which of the following accurately describes ventilation principles associated with a bag-
mask device? - ANSWER-ventilate at a rate of 10 to 12 breaths/minute
if ventilation is ineffective assist ventilations at 10 to 12 breaths per minute or one every
5 to 6 seconds
what is the best measure of the adequacy of cellular perfusion which helps predict the
outcome of resuscitation? - ANSWER-base deficit
is this normal and why? - ANSWER-normal vital signs in pregnancy
resting heart rate increases by 10-20 beats in pregnancy with a small decrease in
systolic BP and larg decrease in diastolic BP due to peripheral resistance
normal fetal heart rate is 120 to 160
