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.

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

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

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

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.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

A firm surface is needed to ensure effective compressions.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

If a choking victim can cough or speak, encourage them to keep coughing rather than immediately performing abdominal thrusts.

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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.

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

In a hospital setting, bag-mask ventilation is the preferred method for delivering rescue breaths.

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