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

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

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

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

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

Single-rescuer infant CPR follows the 30:2 compression-to-ventilation ratio, just like adults.

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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.

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

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

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

A firm surface is needed to ensure effective compressions.

Excessive ventilation can cause complications like gastric inflation.

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