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

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

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

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

Closed-loop communication ensures that orders are acknowledged and carried out correctly.

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

For infants, the correct pulse check location is the brachial artery (inside the upper arm).

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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