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

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

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

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

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

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

Switching roles every 2 minutes prevents rescuer fatigue and minimizes interruptions.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

High-quality CPR for adults requires compressions at least 2 inches deep at a rate of 100-120 per minute.

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

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

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

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

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

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

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

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

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

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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

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

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

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.

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

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

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

A firm surface is needed to ensure effective compressions.

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

Excessive ventilation can cause complications like gastric inflation.

Effective compressions allow full chest recoil, ensuring proper circulation.

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

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

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

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

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.

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

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

Chest compressions should continue while the AED is charging to maintain circulation.

Pulse checks should be performed approximately every 2 minutes when providing rescue breathing.

Visible chest rise confirms that breaths are being delivered effectively.

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

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