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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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

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

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

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.

A firm surface is needed to ensure effective compressions.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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.

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Over-ventilation can increase intrathoracic pressure, reducing venous return and cardiac output.

High-quality CPR for children requires compressing at least 1/3 of the chest depth (about 2 inches or 5 cm).

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