Excessive ventilation can cause complications like gastric inflation.

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

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.

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

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

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

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

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.

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

Each breath should be given over 1 second with just enough volume to see the chest rise.

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

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

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.

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

The E-C clamp technique ensures a tight seal while lifting the jaw for an open airway.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

Excessive ventilation can cause complications like gastric inflation.

A firm surface is needed to ensure effective compressions.

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

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

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

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.

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

Equal chest rise confirms proper ventilation and airway placement.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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