High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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.

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

For single-rescuer infant CPR, use two fingers just below the nipple line to perform compressions.

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

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

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

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.

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

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

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

Breathing assessment should take no more than 10 seconds to avoid delaying CPR.

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

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

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

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

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

Rescuers should switch every 2 minutes (or 5 cycles of compressions) to maintain high-quality CPR.

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

For infants, the correct pulse check location is the brachial artery (inside the upper arm).

The two-thumb encircling hands technique is the preferred method for two-rescuer infant CPR, as it provides better depth and control.

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

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

If a patient is unresponsive with a suspected airway obstruction, chest compressions should be initiated immediately to help clear the airway.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

Infant chest compressions should be at least 1/3 of the chest depth, approximately 1.5 inches (4 cm).
