High-quality CPR requires minimizing interruptions to maintain circulation.

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

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.

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

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

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

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

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

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

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

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

If the patient has a pulse but is not breathing, rescue breathing should be provided with continuous monitoring.

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

If there is any doubt about the presence of a pulse, start chest compressions immediately.

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

Excessive ventilation can cause complications like gastric inflation.

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

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

Most AEDs are programmed to reanalyze the heart rhythm every 2 minutes.

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

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

An AED is used on patients who are unresponsive, pulseless, and not breathing.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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

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

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

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