CPR Airway Management and Rescue Breathing 1 — Questions and Answers
Question 1: What is the correct technique to open an unresponsive adult's airway before delivering rescue breaths?
- Chin-lift only
- Head-tilt chin-lift (Correct answer)
- Jaw-thrust with head tilt
- Neck-tilt chin-lift
Correct answer: Head-tilt chin-lift
The head-tilt chin-lift is the recommended technique for opening the airway in an unresponsive adult without suspected spinal injury.
Question 2: When performing rescue breathing on an adult, how long should each breath be delivered?
- About 0.5 seconds
- About 1 second (Correct answer)
- About 2 seconds
- About 3 seconds
Correct answer: About 1 second
Each rescue breath should be delivered over approximately 1 second to produce visible chest rise without over-inflating the lungs.
Question 3: Which sign confirms that rescue breaths are being delivered effectively?
- Air escaping from the mouth
- Visible chest rise with each breath (Correct answer)
- The victim's skin color improves immediately
- A gurgling sound from the stomach
Correct answer: Visible chest rise with each breath
Visible chest rise with each breath confirms air is entering the lungs and rescue breaths are effective.
Question 4: When should the jaw-thrust maneuver be used instead of the head-tilt chin-lift?
- On all pediatric victims
- When the victim is obese
- When a spinal injury is suspected (Correct answer)
- When CPR is being performed by a single rescuer
Correct answer: When a spinal injury is suspected
The jaw-thrust maneuver is preferred when a spinal injury is suspected because it opens the airway without extending the neck.
Question 5: In hands-only CPR without rescue breaths, which victims are MOST likely to benefit from the addition of rescue breaths?
- Adults who collapsed from cardiac arrest
- Children and drowning victims (Correct answer)
- Elderly patients with heart disease
- Trauma victims with chest injuries
Correct answer: Children and drowning victims
Children and drowning victims experience respiratory arrest before cardiac arrest, so rescue breaths are especially important for oxygenating their blood.
Question 6: What is the correct compression-to-ventilation ratio for single-rescuer adult CPR?
- 15:1
- 15:2
- 30:2 (Correct answer)
- 30:1
Correct answer: 30:2
For single-rescuer adult CPR, the ratio is 30 compressions to 2 rescue breaths per cycle per AHA guidelines.
Question 7: What should a rescuer do if the first rescue breath does not cause the chest to rise?
- Immediately begin chest compressions
- Reposition the airway and attempt a second breath (Correct answer)
- Switch to hands-only CPR permanently
- Increase the force of the next breath significantly
Correct answer: Reposition the airway and attempt a second breath
If the first breath does not produce chest rise, reposition the airway (retilt the head and lift the chin) before attempting a second breath.
