TNCC Practice Exam Questions and
Correct Answers 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
rationale: |hypocapnia, |or |low |levels |of |carbon |dioxide, |will |cause |vasoconstriction, |especially |
in |the |cerebra; |vasculature
