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

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

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

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

Switching roles every 2 minutes ensures high-quality compressions without fatigue.

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

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

A firm surface is needed to ensure effective compressions.

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

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.

Encourage the victim to keep coughing instead of immediately intervening.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

Each breath should be given over 1 second with just enough volume to see the chest rise.

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

A bag-mask device (BVM) is preferred for healthcare providers as it delivers more effective ventilations.

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.

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

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

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

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

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

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

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