CFRN Trauma Test with all Correct & 100% Verified
Answers |Actual Complete Exam |Already Graded A+
Newton's First Law ✔Correct Answer-An object in motion will remain in motion and an object
at rest will remain at rest unless acted upon by a force.
Newton's Second Law ✔Correct Answer-Force (F) = mass (m) X acceleration (a)
Newton's Third Law ✔Correct Answer-For every action, there is an equal and opposite
reaction.
What are the two predictable injury patterns with head on collisions? ✔Correct Answer-1. Up
and over.
2. Down and under.
What injuries are consistent with an up and over injury pattern? ✔Correct Answer-Facial
trauma, cervical trauma, chest/abdominal trauma, and posterior dislocations of the hip.
What injuries are consistent with a down and under injury pattern? ✔Correct Answer-
Multiple fractures of the lower extremities, posterior dislocations of the hip, and abdominal
trauma.
What are the predictable injuries with rear-end collisions? ✔Correct Answer-T12-L1 back
injuries, femur fractures, tib/fib fractures, ankle fractures, and C2 fractures. Evaluate these
patients for frontal impact injuries as well (vehicles often hit whatever is in front of them after
being rear-ended).
What are the predictable injuries with T-bone / lateral impact collisions? ✔Correct Answer-
The patient may have injuries to both the impacted side and the opposite side as well (from
being thrown to the opposite side of the car).
What are the two mechanisms of injury with motorcycle collisions? ✔Correct Answer-1. Head
On
2. Side Impact
What injury patterns are consistent with a head on motorcycle collision? ✔Correct Answer-
This is an up and over injury pattern. The patient will have fractured femurs from hitting the
handlebars and significant head and neck injuries from landing head first into the ground.
What injury patterns are consistent with a side impact motorcycle collision? ✔Correct
Answer-These patients will have open femur fractures, pelvic fractures, and broken ribs (the
arm nearest the ground impacts the ribs causing a compression fracture).
, What injury patterns are consistent with a roll-over collision? What injuries are consistent with
partial ejection? ✔Correct Answer-1. The injury pattern is unpredictable in a roll-over crash.
Roll-overs are the most lethal accidents.
2. Two common injuries with partial ejections are axial loading injuries and degloving / crush
injuries.
What injuries are consistent with a lap belt restraint system? ✔Correct Answer-Lap belts
cause a "clasp knife effect" - the pelvis is held in place while the upper body sustains head, neck,
facial, and chest trauma.
What injuries are consistent with a three point restraint system? ✔Correct Answer-Injuries to
the clavicles, head, and neck.
What injuries are consistent with a passive restraint system (air bag)? ✔Correct Answer-
Injuries include abrasions and fractures to the face and arms. Respiratory problems are also
common due to the powder air bags are stored in. In pediatric patients, airbag deployment can
cause a fatal head injury.
What makes agricultural incidents so deadly? ✔Correct Answer-Agricultural accidents are
usually unwitnessed. Also, there is often a delay in arrival of help due to their rural nature, and
occasionally there is HAZMAT involvement.
What makes tractors so dangerous? ✔Correct Answer-Tractors have a higher center of gravity
so they are prone to roll-overs. End over end accidents have a greater potential for entrapment.
What injury patterns are predictable in ATV roll-over collisions? What type of ATV collisions are
pediatric patients prone to? ✔Correct Answer-1. Crush injuries to lower extremities and
head/chest/sternum/rib fractures from bouncing off the gas well.
2. Pediatric patients are prone to head on collisions with "up and over" injury patterns.
What type of injuries are common in snow-mobile accidents? ✔Correct Answer-Hangman or
"clothes line" injuries.
What type of injuries are most common in rapid vertical deceleration accidents? Who is at
highest risk for these types of injuries? ✔Correct Answer-1. Children sustain head and axial
loading injuries. Adults sustain a "lovers leap" pattern of injuries. "Loves leap" injuries are
fractures of the feet/legs/hips/pelvis and axial loading injuries to the lumbar and cervical spine.
Also included are vertical deceleration injuries to the abdominal organs and Colle's wrist
fractures as the patient falls forward. 2. Adults and children under 5 are at highest risk for
vertical deceleration injuries.
What factors should be considered in patients with implement / stab wounds? ✔Correct
Answer-1. The area of body penetrated.
