High-quality chest compressions are the top priority in cardiac arrest, with ventilation as a secondary focus.

For a single rescuer, the correct ratio is 30 compressions to 2 breaths.

For infants, responsiveness is assessed by tapping the bottom of the foot and shouting.

Rescue breathing is the correct response if the patient has a pulse but no breathing.

The carotid artery is the preferred site for pulse assessment in unresponsive adults.

The first step after turning on an AED is attaching the electrode pads.

For adults with a pulse but not breathing, provide 1 breath every 5-6 seconds.

For children, compress the chest at least 1/3 of its diameter (about 2 inches or 5 cm).

If a choking victim becomes unresponsive and pulseless, CPR should begin immediately, starting with compressions.

The first step is to turn on the AED before attaching pads and following voice prompts.

The first step after turning on an AED is attaching the electrode pads.

A bag-mask device (BVM) is preferred for healthcare providers as it delivers more effective ventilations.

Clear role assignment and minimizing interruptions optimize CPR quality in a team setting.

Rescue breaths should be given before starting chest compressions in drowning victims.

The two-thumb encircling technique is preferred for two-rescuer infant CPR, while single rescuers typically use two fingers.

High-quality chest compressions help circulate oxygenated blood to the brain and heart.

Closed-loop communication ensures that orders are acknowledged and carried out correctly.

A firm surface is needed to ensure effective compressions.

For adults with an advanced airway, ventilation should be given at a rate of 1 breath every 6 seconds.

If the AED does not advise a shock, rescuers should immediately resume CPR.

Early defibrillation is the most critical step in increasing survival rates for patients in cardiac arrest with a shockable rhythm.

Switching roles every 2 minutes ensures high-quality compressions without fatigue.

Encourage the victim to keep coughing instead of immediately intervening.

CPR should continue until the patient shows signs of life, an AED prompts a shock or no shock, or another trained provider takes over.

Rescue breathing should be initiated for a patient with a pulse but no normal breathing.

Chest compressions maintain circulation and deliver oxygenated blood to the brain and heart.

Agonal breathing is a sign of cardiac arrest and CPR should be initiated.

Agonal breathing is a sign of cardiac arrest and CPR should be initiated.

Agonal gasps are not normal breathing and should not delay CPR.

For two-rescuer pediatric CPR, the correct compression-to-ventilation ratio is 15:2.

Chest compressions keep oxygenated blood circulating to the brain and heart until normal function is restored.

Visible chest rise is the best indicator that rescue breaths are effectively ventilating the lungs.

Encourage the victim to keep coughing instead of immediately intervening.

For a single rescuer, the correct ratio is 30 compressions to 2 breaths.

Rescue breathing is the correct response if the patient has a pulse but no breathing.

Rescue breathing is the correct response if the patient has a pulse but no breathing.

Ventilations should be given every 6 seconds when an advanced airway is in place.

Single-rescuer infant CPR follows the 30:2 compression-to-ventilation ratio, just like adults.

The E-C clamp technique ensures a tight seal while lifting the jaw for an open airway.

Excessive ventilation can cause complications like gastric inflation.

Agonal breathing is a sign of cardiac arrest and CPR should be initiated.

Rescue breaths should be given before starting chest compressions in drowning victims.

High-quality CPR requires minimizing interruptions to maintain circulation.

Gasping (agonal breathing) is not normal breathing and should not delay CPR.

Adult chest compressions should be at least 2 inches (5 cm) deep.

Defibrillation should be performed as soon as a shockable rhythm is detected by the AED.

Adult chest compressions should be at least 2 inches (5 cm) deep.

Once an advanced airway is in place, continuous compressions should be given at 100-120 per minute without pausing for breaths.

AED pads should be placed at least 1 inch away from a pacemaker to avoid interference.

In a hospital setting, bag-mask ventilation is the preferred method for delivering rescue breaths.

Rescue breathing is recommended for victims with a pulse but inadequate breathing.

Each breath should be given over 1 second with just enough volume to see the chest rise.

If the patient has a pulse but is not breathing, rescue breathing should be provided with continuous monitoring.

For children with a pulse but no normal breathing, provide rescue breaths at a rate of 12-20 per minute.

Unless a valid DNR order is confirmed, resuscitation efforts should begin.
