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

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

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

If a patient has a pulse but is not breathing adequately, healthcare providers should provide rescue breathing without chest compressions.

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

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

A firm surface is needed to ensure effective compressions.
