Question 1

A bystander says they are unwilling to perform mouth-to-mouth breathing. What should you tell them to do?

Accepted Answer

Perform compression-only (hands-only) CPR

Answer

Hands-only (compression-only) CPR is a recommended alternative for bystanders unwilling or unable to provide rescue breaths, especially in adult sudden cardiac arrest.

Question 2

When inserting an oropharyngeal airway in an adult, what is the correct insertion technique?

Accepted Answer

Insert upside down (curve toward the palate) and rotate 180° as it passes the tongue

Answer

In adults, the OPA is inserted with the tip pointing toward the roof of the mouth, then rotated 180° so the curve follows the tongue as it passes the soft palate.

Question 3

Rescue breathing is being given to a child at what rate?

Accepted Answer

1 breath every 2–3 seconds (20–30/min)

Answer

For a child with a pulse but no breathing, rescue breathing is delivered at 1 breath every 2–3 seconds, equivalent to 20–30 breaths per minute.

Question 4

When performing rescue breathing for an infant, what is the correct mouth-to-airway technique?

Accepted Answer

Mouth covering both the mouth and nose of the infant

Answer

For infants, the rescuer covers both the mouth and nose with their mouth, because the infant's face is small enough to allow a complete seal over both openings.

Question 5

What should you do if you notice the victim's stomach is rising during rescue breaths?

Accepted Answer

Reduce the volume and speed of breaths and ensure the airway is properly positioned

Answer

A rising stomach indicates air is going into the stomach; reduce breath volume and speed, recheck airway positioning, and ensure the head-tilt is adequate.
