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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

The first step is to turn on the AED before attaching pads and following voice prompts.

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

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

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

Over-ventilation can lead to increased intrathoracic pressure, reducing venous return and cardiac output.

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

For children with a pulse but no normal breathing, provide rescue breaths at a rate of 12-20 per minute.

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

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

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

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

Agonal gasps are not normal breathing and should not delay CPR.

Effective compressions allow full chest recoil, ensuring proper circulation.

Infant chest compressions should be at least 1/3 of the chest depth, approximately 1.5 inches (4 cm).

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

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

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

Excessive ventilation can cause complications like gastric inflation.

Encourage the victim to keep coughing instead of immediately intervening.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

The E-C clamp technique ensures a tight seal while lifting the jaw for an open airway.

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

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

Equal chest rise and fall confirms proper ventilation and airway placement.

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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