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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

For suspected spinal injuries, the jaw thrust maneuver is used instead of head tilt-chin lift to maintain spinal alignment.

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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.

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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