Visible chest rise confirms that breaths are being delivered effectively.

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

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

To minimize interruptions in care, breathing and pulse checks should be performed simultaneously, taking no more than 10 seconds.

If a patient has a pulse but is not breathing adequately, healthcare providers should provide rescue breathing without chest compressions.

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

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

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.

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

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

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

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

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

The recommended compression rate is 100-120 compressions per minute.

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

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

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

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

AED pads should be placed at least 1 inch away from a pacemaker to ensure proper function.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

Excessive ventilation can cause complications like gastric inflation.

Unlike adults, the most common cause of cardiac arrest in infants and children is respiratory failure leading to hypoxia.

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

Over-ventilation can lead to increased intrathoracic pressure, reducing venous return and cardiac output.

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

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

A firm surface is needed to ensure effective compressions.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

A firm surface is needed to ensure effective compressions.

A firm surface is needed to ensure effective compressions.

Naloxone should only be administered if opioid overdose is suspected.

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

Reassessment should occur every 5 cycles of CPR (about 2 minutes) unless an AED prompts earlier evaluation.

Over-ventilation can increase intrathoracic pressure, reducing venous return and cardiac output.

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

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

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

Once an advanced airway is in place, continuous compressions are given with 1 breath every 6 seconds.

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