Trauma Systems/MOI & Bleeding
the greatest amount of kinetic energy would be created if a __-pound driver struck a tree while traveling at ___mph
140,50
a healthy adult can tolerate blood loss of up to __ mL over a period of 15 to 20 minutes without any negative effects
500
Decompensated shock in the adult is characterized by
a falling blood pressure
A trauma patient with hypotension secondary to internal hemorrhage should receive IV fluid boluses in order to:
maintain the systolic blood pressure in a low normal range
common airbag related injuries include
minor skin burns
knowledge of kinetics can help the paramedic
predict injury patterns found in a patient
Patients with internal hemorrhage will benefit MOST from
rapid transport
During abrupt deceleration
the neck commonly sustains hyperextension injuries
During an explosion, secondary blast injuries occur when:
the patient is struck by flying debris, such as shrapnel
the MOST significant factor that determines how well the body compensates for blood loss is
the period of time over which the blood is lost
the physiologic process of hemostasis is achieved through:
vasoconstriction and platelet aggregation
a trauma patient with suspected internal hemorrhage and inadequate breathing requires
ventilation assistance and rapid transport
a fall in blood pressure and the resultant changes in plasma osmolality cause the release of
aldosterone and anti-diuretic hormone
The MOST common site of deceleration injury in the chest is the
aorta
A motorcycle rider struck a parked car and was catapulted over the handlebars of his bike. your assessment reveals that he is tachypneic, diaphoretic, and tachycardic. There is no gross external bleeding present. What is the MOST likely cause of this patient's clinical presentation?
bilateral femur fractures
a vagus nerve-mediated form of cardiogenic shock without compensatory vasoconstriction that may be seen following a blast injury would MOST likely present with
bradycardia and hypotension
the law of conservation of energy states that
energy can be neither created nor destroyed; it can only change form
Compared to a handgun, a rifle:
fires at a higher velocity
a patient with hemorrhagic shock would be expected to have
flattened jugular veins
an object increases its kinetic energy more by
increasing it's velocity than by increasing its mass
