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

Equal chest rise confirms proper ventilation and airway placement.

Switching roles every 2 minutes prevents rescuer fatigue and minimizes interruptions.

The best method is to tap the patient and shout to assess for responsiveness.

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

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

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

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 ensure proper function.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

Gasping (agonal breathing) is not normal breathing and should not delay CPR.

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

Chest compressions should continue while the AED is charging to maintain circulation.

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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