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

    Answer: Perform compression-only (hands-only) CPR

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

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

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

    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.

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

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

    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.

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

    Answer: Mouth covering both the mouth and nose of the infant

    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.

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

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

    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.

  6. Which of the following correctly describes the flow of air during rescue breathing into a properly opened airway?

    Answer: Mouth → pharynx → larynx → trachea → lungs

    Air travels from the mouth through the pharynx, past the larynx and vocal cords, down the trachea, and into the lungs where gas exchange occurs.

  7. A rescuer is performing CPR alone and is too fatigued to continue effective compressions. What is the best course of action?

    Answer: Call out for anyone nearby to take over compressions and continue until help arrives

    The rescuer should call for someone else to take over while continuing CPR as best they can — stopping CPR significantly reduces survival chances.
