  1. What does the term 'ROSC' stand for in the context of cardiac arrest management?

    Answer: Return of Spontaneous Circulation

    ROSC stands for Return of Spontaneous Circulation, indicating the heart has resumed effective pumping activity.

  2. A rescuer is alone with an adult who suddenly collapses. The rescuer has a smartphone. What is the correct first action?

    Answer: Check for responsiveness, then call 911 (using speakerphone) while beginning CPR

    Check responsiveness, then activate EMS via speakerphone so you can begin CPR without delay while the operator stays on the line.

  3. Which statement correctly describes the recommended CPR compression rate?

    Answer: 100–120 compressions per minute

    Current AHA guidelines recommend a compression rate of 100–120 compressions per minute for all ages.

  4. An AED is being used on a victim who is lying on a wet dock. What should the rescuer do before attaching the AED?

    Answer: Move the victim to a dry surface and dry the chest before attaching pads

    Move the patient to a dry surface and dry the chest to prevent current from being conducted away from the heart through the water.

  5. During CPR on an adult, the team notices gastric distension. What is the most likely cause?

    Answer: Excessive ventilation volume or rate causing air to enter the stomach

    Excessive ventilation volume or rate forces air into the esophagus and stomach, causing gastric distension and risk of regurgitation.

  6. In which scenario is the use of a bag-mask device preferred over mouth-to-mouth ventilation during CPR?

    Answer: When a trained rescuer is available and a BVM is on hand

    A bag-mask device is preferred when a trained rescuer is available because it can deliver higher oxygen concentrations and reduce exposure risk.

  7. A patient regains a pulse after CPR but remains unconscious and is not breathing adequately. What should the rescuer do?

    Answer: Provide rescue breathing at 10–12 breaths per minute and monitor pulse

    After ROSC, if the patient is not breathing adequately, provide rescue breaths at 10–12/min (one every 5–6 seconds) and monitor for pulse loss.
