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

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

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

High-quality chest compressions are the top priority in cardiac arrest, with ventilation as a secondary focus.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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.

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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.

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