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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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

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