You should NOT remove an embedded object. Instead, apply pressure around it and seek medical help.

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

The best way to treat an electrical shock victim is to first disconnect the power source before providing first aid.

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

A firm surface is needed to ensure effective compressions.

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

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

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

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

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

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

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

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

Applying direct pressure to a wound is the most effective way to stop severe bleeding.

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

Installing carbon monoxide detectors and ensuring proper ventilation can prevent dangerous CO buildup.

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

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

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

For adult CPR, hands should be placed in the center of the chest, on the lower half of the sternum.

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

CPR should begin immediately for a drowning victim who is unresponsive and not breathing to restore oxygen circulation.

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

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

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

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

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

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

A person with low blood sugar should be given a fast-acting sugar source like fruit juice or glucose tablets to restore normal levels.

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

A hypothermic person should be rewarmed gradually using dry blankets and warm fluids. Rapid warming can cause shock.

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

CPR should be stopped only when the person starts breathing normally, emergency responders arrive, or you are too exhausted to continue.

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

Encourage the victim to keep coughing instead of immediately intervening.

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

To check if someone is breathing, look for chest movement, listen for breath sounds, and feel for air movement on your cheek.

If someone is choking and unable to breathe, the first step is to ask if they need help. If they cannot respond, perform abdominal thrusts (Heimlich maneuver).

Frostbite should be treated by gradually warming the affected area using warm water (not hot) and seeking medical help.

If a nosebleed lasts longer than 10 minutes, seek medical attention as it could indicate a more serious problem.

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

Encourage the victim to keep coughing instead of immediately intervening.

Excessive ventilation can cause complications like gastric inflation.

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

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

Laying the person flat and elevating their legs improves circulation and helps restore normal blood flow to the brain.

Asthma inhalers should be used when symptoms appear, not only when a person is unconscious. Delaying treatment can be dangerous.

Low blood sugar (hypoglycemia) can cause confusion, dizziness, sweating, and shakiness. Immediate treatment is needed.

A hypothermic victim should be warmed gradually with dry blankets and warm fluids, avoiding rapid temperature changes.

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