TNCC STUDY GUIDE QUESTIONS AND
ANSWERS WITH SOLUTIONS 2024
Injury to living tissue caused by an external agent that exceeds the tissue's ability to compensate is
termed? - ANSWER trauma
what is a process designed to systematically identify and address external and internal injuries caused by
trauma? - ANSWER trauma nurse process
what are the 3 mechanism terminologies within the study of trauma? - ANSWER Mechanism of injury:
how the injury occurs; what initiates the energy transfer (e.g., hit by an automobile)
Kinematics: how energy is transferred from the source to the patient or parts of the patient; refers to
energy in motion (e.g., explains why pedestrians hit by automobiles generally fly up, over, and down);
involves Newton's three Laws of Motion
Biomechanics: describes what effects are seen following the energy transfer; may refer to cell-level
electrolyte shifts or to the deformity of a bone from an external force; (e.g., why pedestrians hit by
automobiles should be examined for knee, chest, and head injuries)
what is Newton's first law of motion? - ANSWER A body at rest will remain at rest, or in motion will
remain in motion until acted upon by an external force.
Movement -> Energy Transfer -> Countermovement
what is Newton's second law of motion? - ANSWER A body's acceleration depends on net force acting on
the body, and the mass of the body.
Force = mass x acceleration
what is Newton's 3rd law of motion? - ANSWER Every action has an equal and opposite reaction
(transfer of energy).
what are the different types of energy transfer? - ANSWER Mechanical: energy/motion from one object
to another
