Tncc EXAM Questions and Correct Answers
A ____ and ___ approach is used by all members of the trauma team to provide optimal care for the
trauma pt. - Correct Answers Systematic , Organized
Trauma is injury to living tissue caused by ... - Correct Answers An extrinsic agent
A traumatic incident may be classified as ....(assault or suicide) or ... (falls or collisions) - Correct Answers
Intentional;unintentional
.... is the study of energy transfer as it applies to identifying actual or potential injuries - Correct Answers
Kinematics
The general study of forces and their effects - Correct Answers Biomechanics
How external forces in the environment are transferred to the body - Correct Answers Mechanism of
injury
A body at rest will remain at rest, a body in motion will stay in motion - Correct Answers Newton's first
law
Force = mass x acceleration - Correct Answers Newton's second law
For every action there is an equal and opposite reaction - Correct Answers Newton's third law
Energy can neither be created nor destroyed but rather I can change form - Correct Answers Law of
conservation of energy
Kinect is energy is equal to ... - Correct Answers 1/2 the mass x by the velocity squared (v^2)
, Caused by a sudden stop of the body's motion - Correct Answers Deceleration forces
Caused from a sudden and rapid onset of motion ( a Parker car being hit by another vehicle) - Correct
Answers Acceleration forces
An external force applied time of impact, ex. Steering wheels or dashboards that collide with or push up
into a person. - Correct Answers Compression force
.... is the major cause of preventable death after injury - Correct Answers Uncontrolled hemorrhage
.... is suspected in any patient with multi system trauma. - Correct Answers Cervical spine injury
... shock is from hemorrhage and is the leading cause of preventable deaths in trauma patients. Can also
be caused by plasma loss in ... - Correct Answers Hypovolemic; burns
... shock results from hypoperfusion of the tissue due to an obstruction in either the vasculature or
heart. Two examples include.... - Correct Answers Obstructive;tension pneumothorax, cardiac
tamponade. (With tension pneumo the increase in intrathoracic pressure leads to displacement of the
vena cava, obstruction to arrival filling leading to decreased preload and decreased cardiac output)
( with cardiac tamponade there is an accumulation of fluid in the pericardial sac impeding diastolic
expansion and filling leading to decreased preload, stroke volume,CO and end organ perfusion)
... shock occurs as a result of maldistribution of an adequate circulation blood volume with the loss of
vascular tone or increased permeability. 3 examples. - Correct Answers Distributive; anaphylactic, septic
and neurogenic
.... activation: .... are found in the carotid sinus and along the aortic arch, are sensitive to the degree of
stretch in the arterial wall. When the receptors sense a decrease in stretch, they stimulate the
sympathetic nervous system to release Epi, norepi, causing stimulation of cardiac activity and
constriction of blood vessels, which causes a rise in heart rate and diastolic blood pressure - Correct
Answers Baroreceptor activation; baroreceptors
...activation: consist of carotid and aortic bodies. ... detect changes in blood oxygen and Co2 and pH.
When Co2 rises or oxygen level of pH falls these receptors are activated and information is relayed to
