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.

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

Encourage the victim to keep coughing instead of immediately intervening.

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

The first step is to turn on the AED before attaching pads and following voice prompts.

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

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

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

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.

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

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

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

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

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

Equal chest rise and fall confirms proper ventilation and airway placement.

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

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

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

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

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

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

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