TNCC Practice Exam with Rationale LATEST 2024-
2025
QUIZ :What is the key to a high performing trauma team? - ANSWER :effective
communication
rationale: skilled communication, cooperation, and coordination are the
cornerstones of high-performance teams and high-quality trauma care
QUIZ :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: - 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
QUIZ :the major preventable cause of death in the trauma patient is: -
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
QUIZ :the across-the-room observation step in the initial assessment provides
the opportunity to - 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.
QUIZ :Which of the following accurately describes ventilation prinicples
associated with a bag-mask device? - 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
, QUIZ :Which of the following is the best measure of the adequacy of cellular
perfusion and helps to predict the outcome of resuscitation? - 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
QUIZ :What is the safe pharmacological alternative to opioids for rib fracture
pain management in the anticoagulated patient? - ANSWER :intercostal nerve
blocks
rationale: continuous intercostal nerve blocks use long-acting anesthetics and
can provide safe and effective pain management for the anticoagulated
patient.
QUIZ :In a patient with severe traumatic brain injury, hypocapnia causes: -
ANSWER :cerebral vasoconstriction
rationale: hypocapnia, or low levels of carbon dioxide, will cause
vasoconstriction, especially in the cerebra; vasculature
QUIZ :A patient with a knife injury to the neck has an intact airway and is
hemodynamically stable. He complains of difficulty swallowing and speaking.
Further assessment is indicated next for which of the following? -
ANSWER :damage to spinal cord
rationale: penetrating neck trauma may include concurrent injuries to the
spinal cord, airway, or vascular neck structures. With an intact airway and
hemodynamic stability, the other common concurrent injury is to the spinal
cord
QUIZ :What is the appropriate technique for palpating the pelvis for stability? -
ANSWER :apply gentle pressure over the iliac downward and medially
rationale: to assess for pelvic instability, gentle pressure is applied over the iliac
crests downward and medially
QUIZ :a patient with a spinal cord injury at C5 is being cared for in the
emergency department while awaiting transport to a trauma center. which of
