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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

A firm surface is needed to ensure effective compressions.

Visible chest rise confirms that breaths are being delivered effectively.

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

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

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

Equal chest rise confirms proper ventilation and airway placement.

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

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

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).

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.
