An infant is found unresponsive. What is the preferred method to open their airway?
Answer: Neutral to slight head-tilt with gentle chin-lift
For infants, only a slight head-tilt with gentle chin-lift is used because hyperextension can actually close the airway in very young children.
During CPR, if the first rescue breath does not cause chest rise, what should you do before attempting the second breath?
Answer: Reposition the airway and ensure a proper seal, then try again
If chest rise does not occur, reposition the airway (re-tilt the head and re-lift the chin) and ensure a proper mask or mouth seal before attempting the second breath.
Which of the following is the most common cause of airway obstruction in an unconscious adult?
Answer: The tongue falling back into the throat
In unconscious patients, loss of muscle tone causes the tongue to relax and fall back, blocking the airway — which is why airway maneuvers focus on lifting the jaw.
When performing mouth-to-mouth rescue breathing on an adult, how do you prevent air from escaping through the nose?
Answer: Pinch the patient's nose shut with your fingers
The rescuer pinches the patient's nose shut to prevent air from escaping during mouth-to-mouth ventilation.
What is gastric inflation, and why is it a concern during rescue breathing?
Answer: Air forced into the stomach; it can cause vomiting and aspiration
Gastric inflation occurs when rescue breaths force air into the stomach, increasing the risk of regurgitation and aspiration of stomach contents into the lungs.
For a child (ages 1 year to puberty) receiving CPR from two rescuers, what is the correct compression-to-ventilation ratio?
Answer: 15:2
Two-rescuer pediatric CPR uses a 15:2 ratio because children are more likely to have respiratory causes of cardiac arrest and benefit from more frequent ventilations.
What does the acronym 'EC' stand for in the E-C clamp technique for bag-mask ventilation?
Answer: E (three fingers on jaw) and C (thumb and index finger on mask)
The E-C clamp uses three fingers (forming an 'E') to lift the jaw and two fingers (forming a 'C') to press the mask onto the face for a tight seal.
