CPR Airway Management and Rescue Breathing 2 — Questions and Answers
Question 1: How many rescue breaths should be given before resuming chest compressions during adult CPR with two rescuers?
- 1 breath
- 2 breaths (Correct answer)
- 3 breaths
- 4 breaths
Correct answer: 2 breaths
Two rescue breaths are given after every 30 compressions in two-rescuer adult CPR before resuming the next compression cycle.
Question 2: What is the maximum time compressions should be paused to deliver rescue breaths?
- 5 seconds
- 10 seconds (Correct answer)
- 15 seconds
- 20 seconds
Correct answer: 10 seconds
Interruptions to chest compressions should be limited to no more than 10 seconds, including the time taken to deliver rescue breaths.
Question 3: When using a bag-mask device for rescue breathing, how many rescuers are ideally needed to use it effectively?
- 1 rescuer
- 2 rescuers (Correct answer)
- 3 rescuers
- 4 rescuers
Correct answer: 2 rescuers
Two rescuers are ideal when using a bag-mask device: one to maintain a mask seal and head tilt, and one to squeeze the bag.
Question 4: What volume of air should be delivered with each rescue breath to an adult?
- Enough to cause a small flutter in the lips
- Enough to produce visible chest rise (Correct answer)
- The largest breath the rescuer can exhale
- Enough to fill the stomach
Correct answer: Enough to produce visible chest rise
Each rescue breath should deliver just enough volume to produce visible chest rise, approximately 500–600 mL, without causing gastric inflation.
Question 5: Which of the following MOST commonly causes gastric inflation during rescue breathing?
- Breathing too slowly
- Delivering breaths that are too forceful or too fast (Correct answer)
- Using the jaw-thrust maneuver
- Failing to pinch the nose shut
Correct answer: Delivering breaths that are too forceful or too fast
Excessive force or speed when delivering rescue breaths can cause air to enter the stomach (gastric inflation) instead of the lungs.
Question 6: When performing mouth-to-mouth rescue breathing, the rescuer should pinch the victim's nose shut to:
- Prevent infection from spreading
- Stop air from escaping through the nose (Correct answer)
- Keep the airway open
- Stimulate the victim's breathing reflex
Correct answer: Stop air from escaping through the nose
Pinching the nose shut prevents the delivered breath from escaping through the nostrils, ensuring air enters the lungs.
Question 7: What is the purpose of the recovery position after a victim regains a pulse and begins breathing normally?
- To make CPR easier if the victim stops breathing again
- To maintain an open airway and reduce the risk of aspiration (Correct answer)
- To lower the victim's blood pressure
- To allow the rescuer to rest while waiting for EMS
Correct answer: To maintain an open airway and reduce the risk of aspiration
The recovery position keeps the airway open and allows fluids (vomit, blood) to drain out of the mouth, reducing the risk of aspiration.
