BLS Airway Management & Ventilation 3

Question 1

An infant is found unresponsive. What is the preferred method to open their airway?

Accepted Answer

Neutral to slight head-tilt with gentle chin-lift

Answer

For infants, only a slight head-tilt with gentle chin-lift is used because hyperextension can actually close the airway in very young children.

Question 2

During CPR, if the first rescue breath does not cause chest rise, what should you do before attempting the second breath?

Accepted Answer

Reposition the airway and ensure a proper seal, then try again

Answer

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.

Question 3

Which of the following is the most common cause of airway obstruction in an unconscious adult?

Accepted Answer

The tongue falling back into the throat

Answer

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.

Question 4

When performing mouth-to-mouth rescue breathing on an adult, how do you prevent air from escaping through the nose?

Accepted Answer

Pinch the patient's nose shut with your fingers

Answer

The rescuer pinches the patient's nose shut to prevent air from escaping during mouth-to-mouth ventilation.

Question 5

What is gastric inflation, and why is it a concern during rescue breathing?

Accepted Answer

Air forced into the stomach; it can cause vomiting and aspiration

Answer

Gastric inflation occurs when rescue breaths force air into the stomach, increasing the risk of regurgitation and aspiration of stomach contents into the lungs.
