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

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

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

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

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

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

Defibrillation should be performed as soon as a shockable rhythm is detected by the AED.

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

Switching roles every 2 minutes ensures high-quality compressions without fatigue.

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

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

Visible chest rise is the best indicator that rescue breaths are effectively ventilating the lungs.

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

For children, compress the chest at least 1/3 of its diameter (about 2 inches or 5 cm).

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

Excessive ventilation can cause complications like gastric inflation.

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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