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

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

A firm surface is needed to ensure effective compressions.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

Excessive ventilation can cause complications like gastric inflation.

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

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

Visible chest rise confirms that breaths are being delivered effectively.

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

Excessive ventilation can cause complications like gastric inflation.

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

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

AED pads should be placed at least 1 inch away from a pacemaker to avoid interference.

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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.

Naloxone should only be administered if opioid overdose is suspected.

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

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

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

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