Tncc Questions with CORRECT Answers (Verified Update)
Q1: What tools can be used to promote communication within a team member? What are the
benefits of each?
Answer: *SBAR:* Situation, Background, Assessment, Recommendations-To provide a framework for
communication among members of the healthcare team
Q2: How external energy forces in the environment are transferred to the body
Answer: Mechanism of Injury
Q3: Newton's First Law of Motion
Answer: A body rest will remain at rest, and a body in motion will stay in motion
Q4: Newton's Second Law of Motion
Answer: Force = mass x acceleration
Q5: Newton's Third Law of Motion
Answer: For every action, there is an equal and opposite reaction
Q6: Law of Conservation of Energy
Answer: Energy can neither be created nor destroyed, but can change form
Q7: Describe how Newton's Laws of Motion and the Law of Conservation affect energy transfer in
traumatic injury, and give an example
Answer: 1st: weight and speed are reasonable substitutions for mass and velocity, higher mass
and/or higher speed delivers greater energy -2nd: an object's velocity changes when it is
subjected to an external force; heavier objects require more force to accelerate (or
decelerate) them -3rd: -Conservation
,Q8: Differentiate between internal and external forces of energy transfer in the context of
trauma
Answer: *External forces:* -Can be exerted on the body by deceleration, acceleration, compression
forces -Deceleration forces include those applied in falls and collisions where injuries are
cause by a sudden stop in the body's motion -Acceleration forces are not as common as
deceleration forces and result from a sudden and rapid onset of motion, like a parked car
that is hit y vehicle traveling at the high rate of speed -Compression force is an external
force applied at time of impact, like stationary objects- dashboards or steering wheels that
collide with or push up into a person. Objects in motion- bullets, stabbing, bats, balls, fists
and feet, or heavy falling objects -Blast forces
Q9: How do internal forces protect the body from injury?
Answer: *Compression strength:* ability of tissue to resist crush injury or force
Q10: Differentiate between deceleration and acceleration forces
Answer: *Deceleration forces:* occurs as energy that is dispersed from the moving object. For
example, a body sliding across pavement transfers energy to the pavement through friction
*Acceleration forces:* the sample principles used to describe deceleration forces apply to
acceleration forces. For example, as energy is slowly transferred to the stationary pieces of
gravel, the gravel accelerates while the body and internal organs continue to travel as a
single entity
Q11: Describe the three impacts in the motor vehicle impact sequence
Answer: The first impact occurs when the vehicle hits another object such asa tree. The occupants
experience a relative acceleration as the vehicle stops over the distance of the crushing
metal, but they have not begun to absorb the energy if the abrupt vehicle stop
Q12: Describe the usefulness of the Haddon Matrix in prevention and reduction of injury
Answer: Changing human behavior as a means of preventing injury, primarily in MVCs -Places
emphasis of countermeasures, which are more effective on changing human behavior -Led
to the introduction of passive restraints, airbags, vehicle design, and road blueprints as
opposed to active restraints -Describes three phases of the injury event: pre-event, the
event, and post-event -For each phase of the event, countermeasures for prevention can be
applied -They include the host (human), the agent (motor vehicle), and the physical
environment (socioeconomic environment)
, Q13: Fill in the blanks of the steps of initial assessment: Preparation and _____ Across-the-room
observation to identify any uncontrolled ___________ and reprioritize to
___________________
Answer: Preparation and triage Across-the-room observation to identify any uncontrolled
hemorrhage and reprioritize to CABC
Q14: Reevaluation for signs of internal uncontrolled hemorrhage and ________
Answer: Pneumothorax
Q15: Secondary survey with reevaluation adjuncts
Answer: H-Head to toe assessment I-Inspect posterior suface
Q16: Why is there repeated emphasis on assessment for hemorrhage throughout the initial
assessment?
Answer: Uncontrolled hemorrhage is the major cause of preventable death after injury
Q17: What method of opening airway is recommended for use in trauma?
Answer: Jaw thrust
Q18: Describe the current guidelines for volume resuscitation in hemorrhagic shock
Answer: Component therapy is now suggested for fluid resuscitation to replace patient losses,
including administer red blood cells, plasma, and platelets. This balanced approach to
resuscitation includes massive transfusion so that oxygen delivery is optimized, acidosis is
correct, coagulopathy is prevented, and damage control surgery is performed
Q19: Exposure and environmental control is included in the Primary survey. Why is it such a high
priority?
Answer: Hypothermia combined with hypotension and acidosis is a potentially lethal combination in
the injured patient. This assessment parameter is intentionally placed in the primary survey
in order to assure that aggressive measures are taken to prevent the loss of body heat
