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

Equal chest rise confirms proper ventilation and airway placement.

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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.

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

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

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

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

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

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

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

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

Chest compressions should continue while the AED is charging 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.

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

Chest compressions keep oxygenated blood circulating to the brain and heart until normal function is restored.

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

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

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

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

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