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

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

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

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

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

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

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.

Encourage the victim to keep coughing instead of immediately intervening.

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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

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

Closed-loop communication ensures that orders are acknowledged and carried out correctly.

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

Over-ventilation can lead to increased 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).

A firm surface is needed to ensure effective compressions.

Visible chest rise confirms that breaths are being delivered effectively.

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

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.

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

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

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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