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

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

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

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

Over-ventilation can increase intrathoracic pressure, reducing venous return and cardiac output.

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

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

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

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

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

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

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

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

Naloxone should only be administered if opioid overdose is suspected.

Equal chest rise confirms proper ventilation and airway placement.

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

High-quality CPR requires minimizing interruptions to maintain circulation.

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

The correct compression depth for adult CPR is at least 2 inches (5 cm).

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

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

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

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

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

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

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

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

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

A firm surface is needed to ensure effective compressions.

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.

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

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

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

Encourage the victim to keep coughing instead of immediately intervening.

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

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

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

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

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

For adults with an advanced airway, ventilation should be given at a rate of 1 breath every 6 seconds.

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

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