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

Switching roles every 2 minutes minimizes interruptions and maintains high-quality CPR.

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

Visible chest rise is the best indicator that rescue breaths are effectively ventilating the lungs.

Encourage the victim to keep coughing instead of immediately intervening.

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

Pediatric AED pads should be used for children under 8 years old, if available.

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

A firm surface is needed to ensure effective compressions.

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

Encourage the victim to keep coughing instead of immediately intervening.

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.

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

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

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

Excessive ventilation can cause complications like gastric inflation.

Naloxone should only be administered if opioid overdose is suspected.

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

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

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.

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

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

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

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

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

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

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

For adults with a pulse but not breathing, provide 1 breath every 5-6 seconds.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Visible chest rise confirms that breaths are being delivered effectively.

AED pads should be placed at least 1 inch away from a pacemaker to ensure proper function.

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

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

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.

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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