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

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.

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

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

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

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

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

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

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

Reassessment should occur every 5 cycles of CPR (about 2 minutes) unless an AED prompts earlier evaluation.

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

If the patient has a pulse but is not breathing, rescue breathing should be provided with continuous monitoring.

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

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

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

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.

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

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

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

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

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

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

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

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

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

Chest compressions keep oxygenated blood circulating to the brain and heart until normal function is restored.

Breaths should be delivered over 1 second each to produce visible chest rise.

Equal chest rise confirms proper ventilation and airway placement.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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