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

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

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

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

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

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

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

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

If a choking victim becomes unresponsive and pulseless, CPR should begin immediately, starting with compressions.

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

Defibrillation should be performed as soon as a shockable rhythm is detected by the AED.

Equal chest rise confirms proper ventilation and airway placement.

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

A firm surface is needed to ensure effective compressions.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

For suspected spinal injuries, the jaw thrust maneuver is used instead of head tilt-chin lift to maintain spinal alignment.

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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.

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

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

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

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

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

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