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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

High-quality chest compressions help circulate oxygenated blood to the brain and heart.

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

For a choking infant, back slaps and chest thrusts should be used instead of abdominal thrusts.

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

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

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 limited to 10 seconds to avoid delaying CPR.

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

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

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

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

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

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.

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

Effective compressions allow full chest recoil, ensuring proper circulation.
