CPR Techniques 3 — Questions and Answers
Question 1: When giving rescue breaths, how long should each breath last?
- About 1 second (Correct answer)
- About 5 seconds
- About 10 seconds
- Less than half a second
Correct answer: About 1 second
Each rescue breath should be delivered over about 1 second and produce visible chest rise.
Question 2: What is the proper head position to open the airway in an unresponsive adult with no suspected spinal injury?
- Chin tucked to chest
- Head-tilt, chin-lift (Correct answer)
- Head turned to the side
- Neck flexed forward
Correct answer: Head-tilt, chin-lift
The head-tilt, chin-lift maneuver opens the airway in adults without suspected neck injury.
Question 3: If the first rescue breath does not make the chest rise, what should you do?
- Give up on breaths
- Reposition the head and try again (Correct answer)
- Give 5 more breaths quickly
- Press on the stomach
Correct answer: Reposition the head and try again
Re-tilt the head to reopen the airway and attempt the breath once more.
Question 4: What airway technique is preferred when a spinal injury is suspected?
- Head-tilt, chin-lift
- Jaw-thrust without head tilt (Correct answer)
- Full neck extension
- Turning the head sideways
Correct answer: Jaw-thrust without head tilt
The jaw-thrust maneuver opens the airway while minimizing neck movement.
Question 5: During mouth-to-mouth ventilation, what must you do to prevent air from escaping?
- Pinch the victim's nose closed (Correct answer)
- Cover both eyes
- Tilt the head forward
- Hold the victim's arms down
Correct answer: Pinch the victim's nose closed
Pinching the nose ensures air enters the lungs rather than escaping through the nostrils.
Question 6: What is a sign that a rescue breath was effective?
- The stomach expands
- The chest visibly rises (Correct answer)
- The victim coughs immediately
- Air leaks from the ears
Correct answer: The chest visibly rises
Visible chest rise indicates air is reaching the lungs.
Question 7: Why should rescuers avoid giving breaths that are too large or too forceful?
- It wastes oxygen supply
- It can push air into the stomach and cause vomiting (Correct answer)
- It slows compression rate
- It damages the lungs permanently
Correct answer: It can push air into the stomach and cause vomiting
Excessive breaths inflate the stomach, raising the risk of regurgitation and aspiration.
