How does the AHA define adults, children and infants? - Correct Answer-Adults =
adolescents (ie., after the onset of puberty and older
Children = 1 year of age to onset of puberty
Infants = less than 1 year of age (excluding newly born infants in the delivery room)
, What are signs of puberty? - Correct Answer-Chest or underarm hair in males and any
breast development in females.
The BLS Course focuses on preparing students to perform ___ skills. - Correct Answer-
CPR
What are the two components of CPR? - Correct Answer-1) chest compressions
2) breaths
What do these all describe?:
*Start compressions within 10 seconds
*Push hard, push fast
*Allow complete chest recoil
*Minimize interruptions
*Give effective breaths
*Avoid excessive ventilation - Correct Answer-High-Quality CPR
How soon should compressions be started after the recognition of cardiac arrest? -
Correct Answer-Within 10 seconds
At what rate should chest compressions be given? - Correct Answer-100-120
beats/minute
At what depth should chest compressions be given in adults? - Correct Answer-At least
2 inches (5 centimeters)
At what depth should chest compressions be given in children? - Correct Answer-At
least 1/3 depth of chest , about 2 inches (5 centimeters)
At what depth should chest compressions be given in infants? - Correct Answer-At least
1/3 depth of chest, about 1.5 inches (4 centimeters)
High-quality CPR includes minimizing interruptions in chest compressions. Try to limit
interruptions to less than __ seconds. - Correct Answer-10
What constitutes an effective breath in high-quality CPR? - Correct Answer-Making the
chest rise
Chest compressions are more often too shallow than too deep. However, research
suggest that compression depth greater than 2.4 inches (6 centimeters) in adults may
cause injuries. If you have a CPR quality feedback device, what is the optimal target for
compression depth? - Correct Answer-2 - 2.4 inches (5 - 6 cm)
With adults, what is the first thing you should do when you recognize the adult is not
responsive? - Correct Answer-Activate EMS or ask someone to do it.
