Paramedics have transported a young infant with a history of apnea to the
Emergency Department. When they arrive in the Emergency Department
you note that the infant is breathing slowly, is not responsive to stimulation,

minute. What should your next action be?
a. Immediately provide rescue breaths with a bag-mask device and oxygen
b. Immediately check for a pulse and other signs of circulation to determine if
chest compressions are needed.
c. Administer oxygen but do not provide ventilations or compressions.
d. Attempt to relieve foreign-body airway obstruction.

What is the correct BLS sequence for lone rescuers for out of hospital

a. Phone the emergency response number immediately, then return to the victim,
and check for signs of circulation; if there are no signs of circulation, open the
airway and check for breathing, give rescue breaths.
b. Open the airway and check for breathing; if there is no effective breathing,
give 2 rescue breaths, check for signs of circulation, and if there is no signs of
circulation, begin chest compressions and phone 911 after approximately 1

c. Phone 911 or the emergency response number, open the airway, and check for
breathing; if there is no breathing give 2 rescue breaths, check for signs of
