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

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

Equal chest rise and fall confirms proper ventilation and airway placement.

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

Unlike adults, the most common cause of cardiac arrest in infants and children is respiratory failure leading to hypoxia.

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

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

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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