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

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

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

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

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

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

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.

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

For an unresponsive, pulseless patient, immediate chest compressions are the priority.

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

The best method is to tap the patient and shout to assess for responsiveness.

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

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.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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.

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

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

Most AEDs are programmed to reanalyze the heart rhythm every 2 minutes.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

If a choking victim can cough or speak, encourage them to keep coughing rather than immediately performing abdominal thrusts.

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

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

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

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