High-quality CPR requires minimizing interruptions to maintain circulation.

A firm surface is needed to ensure effective compressions.

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

Visible chest rise confirms that breaths are being delivered effectively.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

Single-rescuer infant CPR follows the 30:2 compression-to-ventilation ratio, just like adults.

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

For two-rescuer infant CPR, the correct ratio is 15:2, not 30:2.

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

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

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.

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

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

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

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

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

If the AED does not advise a shock, rescuers should immediately resume CPR.

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

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

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

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

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

AED pads should be placed at least 1 inch away from a pacemaker to ensure proper function.

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

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

A firm surface is needed to ensure effective compressions.

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

Effective compressions allow full chest recoil, ensuring proper circulation.
