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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

To minimize interruptions in care, breathing and pulse checks should be performed simultaneously, taking no more than 10 seconds.

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

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.

A bag-mask device (BVM) is preferred for healthcare providers as it delivers more effective ventilations.

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

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

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

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

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

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

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

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

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

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