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

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

AED pads should be placed at least 1 inch away from a pacemaker to avoid interference.

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

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

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

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

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.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

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

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

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

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

CPR should continue until the patient shows signs of life, an AED prompts a shock or no shock, or another trained provider takes over.

Visible chest rise confirms that breaths are being delivered effectively.

A firm surface is needed to ensure effective compressions.

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

For a responsive choking adult, abdominal thrusts (Heimlich maneuver) should be used.
