Which of the following accurately describes ventilation principles associated
with use of a bag-mask device for an adult?
A.Compress the bag-mask device at a rate of one breath every 6 seconds.
B.Delivers 100% oxygen.
C.Squeeze the bag-mask device completely for each breath.
D.Maintain the oxygen saturation levels between 92% and 94%.
✓ ~~> A.Compress the bag-mask device at a rate of one breath every
6 seconds.
Rationale
A: If breathing is ineffective for an adult, assist ventilations by compressing the
bag-mask device at a rate of one breath every 6 seconds. B: Delivery of
oxygen is helpful for improving oxygenation, not for ventilation.C: Squeeze
the bag just enough to produce visible chest rise every 6 seconds. D: Delivery
of oxygen is helpful for improving oxygenation, not ventilation. Additionally,
oxygen saturation of 94% or higher is associated with effective, adequate
oxygenation in most patients.

Treatment for frostbite can include which of the following interventions?
A.Warm the affected part over 30 to 60 minutes
B.Use gentle friction to improve circulation
C.Administer tissue plasminogen activator
D.Leave all of the blisters intact
✓ ~~> C.Administer tissue plasminogen activator
Rationale
A: Warming for frostbite is done gently, over 15 to 30 minutes. B: Friction, even
gentle friction, is avoided to prevent tissue damage. C: With frostbite,
thrombus formation is a risk. Tissue plasminogen activator, a thrombolytic
medication, has been effective in maintaining perfusion and decreasing the
need for amputation when administered within 24 hours of rewarming. D:
Large blisters, whether clear or hemorrhagic, that can affect movement
should be drained. Smaller blisters should be left intact.
What is the leading cause of preventable death for the trauma patient in the
prehospital environment?
A.Airway compromise

B.Ineffective ventilation
C.Secondary head injury
D.Uncontrolled external hemorrhage
✓ ~~> D.Uncontrolled external hemorrhage
Rationale:
A: Uncontrolled external hemorrhage is the leading cause of preventable
death after injury in the prehospital environment, not airway compromise. B:
Uncontrolled external hemorrhage is the leading cause of preventable death
after injury in the prehospital environment, not ineffective ventilation. C:
Uncontrolled external hemorrhage is the leading cause of preventable death
after injury in the prehospital environment, not secondary head injury. D:
Uncontrolled external hemorrhage is the leading cause of preventable death
after injury in the prehospital environment; assessment to identify uncontrolled
external hemorrhage is key to the initial assessment process, beginning with
the general impression.
