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

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

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

For suspected spinal injury, the jaw thrust maneuver should be used instead of head tilt-chin lift.

If there is any doubt about the presence of a pulse, start chest compressions immediately.

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

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

Switching roles every 2 minutes minimizes interruptions and maintains high-quality CPR.

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

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

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

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

Rescuers should switch every 2 minutes to maintain high-quality CPR and prevent fatigue.

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

Encourage the victim to keep coughing instead of immediately intervening.

For suspected spinal injuries, the jaw thrust maneuver is used instead of head tilt-chin lift to maintain spinal alignment.

For adult CPR, compressions should be performed with two hands, one on top of the other, placed on the lower half of the sternum.

If a choking victim becomes unresponsive, emergency services should be activated, and CPR should begin immediately.

Encourage the victim to keep coughing instead of immediately intervening.

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

Pulse checks should be limited to 10 seconds to avoid delaying CPR.

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

Visible chest rise confirms that breaths are being delivered effectively.

High-quality CPR requires minimizing interruptions to maintain circulation.

An AED analyzes the heart rhythm and delivers a shock if a shockable rhythm is present.

After a shock is delivered, chest compressions should resume immediately to maintain circulation.

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

An AED is used on patients who are unresponsive, pulseless, and not breathing.

A firm surface is needed to ensure effective compressions.

Chest compressions should continue while the AED is charging to maintain circulation.

Excessive ventilation can cause complications like gastric inflation.

Pulse checks should be performed approximately every 2 minutes when providing rescue breathing.

Breaths should be delivered over 1 second each to produce visible chest rise.

Equal chest rise and fall confirms proper ventilation and airway placement.

High-quality CPR requires minimizing interruptions to maintain circulation.

High-quality CPR for adults requires compressions at least 2 inches deep at a rate of 100-120 per minute.

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

High-quality CPR for children requires compressing at least 1/3 of the chest depth (about 2 inches or 5 cm).

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

The best way to ensure effective ventilation is by observing visible chest rise with each breath.

When a shockable rhythm is detected, defibrillation should be performed as soon as possible.

Excessive ventilation can cause complications like gastric inflation.

The correct compression depth for adult CPR is at least 2 inches (5 cm).

In BLS, medication administration is not a designated role—this falls under ACLS-level care.

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

Effective compressions allow full chest recoil, ensuring proper circulation.

Switching roles every 2 minutes prevents rescuer fatigue and minimizes interruptions.

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