CPR Techniques for Adults & Children 3 — Questions and Answers
Question 1: For an infant, how many fingers or what technique is used by a single rescuer for compressions?
- Two fingers in the center of the chest (Correct answer)
- The heel of one hand
- Both hands interlocked
- A closed fist
Correct answer: Two fingers in the center of the chest
A single rescuer uses two fingers just below the nipple line on an infant.
Question 2: What is the compression depth for a child (age 1 to puberty)?
- About 2 inches (5 cm) or one-third the chest depth (Correct answer)
- At least 3 inches
- About half an inch
- Exactly 1 inch
Correct answer: About 2 inches (5 cm) or one-third the chest depth
Children should be compressed about 2 inches or one-third the depth of the chest.
Question 3: When two rescuers perform CPR on an infant, which technique is preferred for compressions?
- Two-thumb encircling hands technique (Correct answer)
- One-hand heel technique
- Two-finger technique
- Full palm technique
Correct answer: Two-thumb encircling hands technique
With two rescuers, the two-thumb encircling hands technique provides better compressions for infants.
Question 4: What is the correct head position to open the airway in an unresponsive adult with no suspected neck injury?
- Head-tilt, chin-lift (Correct answer)
- Hyperextend the neck fully backward
- Tuck the chin to the chest
- Turn the head to the side
Correct answer: Head-tilt, chin-lift
The head-tilt, chin-lift maneuver opens the airway when no neck injury is suspected.
Question 5: If a neck or spinal injury is suspected, which airway technique should be used?
- Jaw-thrust maneuver (Correct answer)
- Head-tilt, chin-lift
- Full neck extension
- Chin-to-chest flexion
Correct answer: Jaw-thrust maneuver
The jaw-thrust opens the airway without moving the neck when spinal injury is suspected.
Question 6: How much air should each rescue breath deliver?
- Just enough to make the chest visibly rise (Correct answer)
- As much as possible to fully inflate the lungs
- A small puff with cheeks only
- Two full deep breaths held for 5 seconds
Correct answer: Just enough to make the chest visibly rise
Each breath should last about one second and produce visible chest rise.
Question 7: What should you do if your first rescue breath does not make the chest rise?
- Reposition the head and try again (Correct answer)
- Give five more breaths quickly
- Begin abdominal thrusts immediately
- Stop CPR entirely
Correct answer: Reposition the head and try again
If the chest does not rise, re-tilt the head to reopen the airway before the next breath.
