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

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

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

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

Encourage the victim to keep coughing instead of immediately intervening.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Before starting CPR, check for a pulse for no more than 10 seconds to determine if compressions are needed.

Switching roles every 2 minutes prevents rescuer fatigue and ensures continuous, high-quality CPR.

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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.

Visible chest rise confirms that breaths are being delivered effectively.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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