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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

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

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

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 ensure proper function.

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

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

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

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

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

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

Rescue breathing should be initiated for a patient with a pulse but no normal breathing.

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

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

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

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

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

Over-ventilation can lead to increased intrathoracic pressure, reducing venous return and cardiac output.

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