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

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

For adults with an advanced airway, ventilation should be given at a rate of 1 breath every 6 seconds.

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

Pediatric AED pads should be used for children under 8 years old, if available.

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

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

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

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

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

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

Shifting the uterus to the left reduces pressure on the inferior vena cava, improving circulation.

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

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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