BLS Adult, Child & Infant Resuscitation 2 — Questions and Answers
Question 1: When performing CPR on an infant, which technique is recommended for chest compressions when a single rescuer is present?
- Two-finger technique on the center of the chest just below the nipple line (Correct answer)
- One-hand technique using the heel of the hand
- Two-thumb encircling technique with both hands
- Three-finger technique on the lower half of the sternum
Correct answer: Two-finger technique on the center of the chest just below the nipple line
A single rescuer should use two fingers placed just below the nipple line on the center of the chest for infant compressions.
Question 2: For a child victim (ages 1 to puberty), what is the recommended compression depth during CPR?
- At least 1 inch
- At least 2 inches (Correct answer)
- At least 1.5 inches
- At least 2.5 inches
Correct answer: At least 2 inches
For children, compressions should be at least 2 inches (5 cm) deep to be effective.
Question 3: A 2-rescuer team is performing CPR on an infant. Which compression technique is preferred?
- Two-finger technique
- Two-thumb encircling technique (Correct answer)
- One-hand heel technique
- Palm-only technique
Correct answer: Two-thumb encircling technique
The two-thumb encircling technique is preferred in two-rescuer infant CPR because it produces better compressions.
Question 4: After delivering rescue breaths to an adult victim during CPR, the rescuer notices the chest does not rise. What should be done first?
- Increase the force of the next breath
- Reposition the head and lift the chin before reattempting (Correct answer)
- Switch to compressions-only CPR immediately
- Check the victim's pulse before continuing
Correct answer: Reposition the head and lift the chin before reattempting
If the chest does not rise, the airway may be improperly positioned, so the rescuer should reposition the head-tilt chin-lift before reattempting.
Question 5: When should a rescuer begin CPR on a child who is unresponsive and not breathing normally?
- Only after confirming no pulse for at least 10 seconds
- Immediately, starting with 30 compressions (Correct answer)
- After calling 911 and waiting for instructions
- After delivering 2 rescue breaths first
Correct answer: Immediately, starting with 30 compressions
BLS guidelines direct rescuers to begin CPR immediately with 30 compressions (or 15 for two-rescuer child CPR) without delaying for prolonged pulse checks.
Question 6: Which of the following best describes the correct head position to open the airway in an adult with no suspected spinal injury?
- Head neutral, chin slightly down
- Head-tilt chin-lift, tilting the head back fully (Correct answer)
- Jaw-thrust only, keeping head neutral
- Head turned to the side to prevent aspiration
Correct answer: Head-tilt chin-lift, tilting the head back fully
The head-tilt chin-lift maneuver is the standard method to open the airway when no spinal injury is suspected.
Question 7: What is the maximum time a rescuer should spend checking for a pulse before starting CPR?
- 5 seconds
- 10 seconds (Correct answer)
- 15 seconds
- 30 seconds
Correct answer: 10 seconds
Pulse checks should take no more than 10 seconds; if no pulse is felt within that time, CPR should begin.
