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

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

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

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

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

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

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

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

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

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.

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

Excessive ventilation can cause complications like gastric inflation.

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

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

Before starting CPR, check for a pulse for no more than 10 seconds to determine if compressions are needed.

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

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

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

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 recommended for victims with a pulse but inadequate breathing.

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

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

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.

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

A firm surface is needed to ensure effective compressions.

Excessive ventilation can cause complications like gastric inflation.

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

Pulse checks should be performed approximately every 2 minutes when providing rescue breathing.

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

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

Unlike adults, the most common cause of cardiac arrest in infants and children is respiratory failure leading to hypoxia.

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

A firm surface is needed to ensure effective compressions.

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

Visible chest rise confirms that breaths are being delivered effectively.

Encourage the victim to keep coughing instead of immediately intervening.

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

Excessive ventilation can cause complications like gastric inflation.

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

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