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

You should always handle a knocked-out tooth by the crown, NOT the root, to protect its delicate tissues for reattachment.

A person in cardiac arrest will be unresponsive, have no pulse, and will not be breathing normally.

Unlike heat exhaustion, heat stroke causes hot, dry skin and confusion, and is a medical emergency.

FAST stands for Face drooping, Arm weakness, Speech difficulty, and Time to call 911. Recognizing these signs early can save lives.

Lying the person flat with legs elevated improves circulation and blood flow to vital organs.

Never place anything in a person's mouth during a seizure. Instead, clear the area around them and let the seizure pass.

Third-degree burns destroy nerve endings, which may result in no pain. However, they are the most severe and require medical treatment.

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

Compressions should be at least 2 inches (5 cm) deep to effectively circulate blood.

Never hold down a person having a seizure. Instead, clear the area and protect their head while allowing the seizure to pass.

Human bites can be more dangerous than animal bites because they often introduce harmful bacteria, leading to infection.

Applying ice directly to a burn can cause further tissue damage. Instead, use cool (not ice-cold) running water.

A splint prevents movement of a broken or injured limb to avoid further damage.

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

A person with a spinal injury should not be moved unless absolutely necessary. Keep them still and stabilize their head and neck.

For mild allergic reactions, an antihistamine like diphenhydramine (Benadryl) can help reduce symptoms.

If a person is unresponsive and has no pulse, CPR should be started immediately to maintain circulation and oxygenation.

Applying firm, direct pressure is the most effective way to stop bleeding from a deep laceration.

An EpiPen (epinephrine) is the first-line treatment for anaphylaxis, as it quickly reverses severe allergic reactions.

The first step is to get the victim to fresh air immediately. Carbon monoxide is dangerous because it is colorless and odorless.

Moving the person to a cool environment and providing fluids helps reduce body temperature gradually.

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

If an inhaler does not relieve an asthma attack, call 911 immediately, as the attack may become life-threatening.

Agonal gasps (irregular, gasping breaths) are not normal breathing. CPR should be started immediately.

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

Carbon monoxide is a colorless, odorless, and tasteless gas, making it extremely dangerous.

Common symptoms of poisoning include nausea, vomiting, confusion, and difficulty breathing.

If you suspect a heart attack, the first step is to call 911 immediately. Early treatment can prevent serious damage or death.

Carbon monoxide poisoning prevents oxygen from binding to red blood cells, leading to suffocation and organ failure.

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

A concussion can have delayed symptoms, so the person should be monitored closely and should avoid activities that worsen their condition.

If a person is unable to speak or cough, perform the Heimlich maneuver (abdominal thrusts) to help expel the obstruction.

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

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

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

Flushing the eye with water for at least 15 minutes helps remove the chemical and prevent further damage.

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

Before assisting a victim, always turn off the power source to prevent further injury.

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

Diabetic emergencies can cause confusion, dizziness, sweating, and shakiness due to abnormal blood sugar levels.

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

During a seizure, keep the person safe by clearing the area and placing them on their side to prevent choking. Do NOT hold them down.

An AED is used when a person is unresponsive and has no pulse. It delivers a shock only if needed.

Frostbitten areas should be warmed slowly using warm water (not hot) to avoid further damage.

Do NOT push the bone back in. Instead, cover the area with a sterile dressing and immobilize the limb while waiting for emergency help.

Running cool (not ice-cold) water over a minor burn for several minutes helps reduce heat and prevent further tissue damage.

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

Carbon monoxide poisoning is life-threatening, and the first step is to move the victim to fresh air immediately.

Vomiting can worsen certain types of poisoning, such as chemical or petroleum-based substances. Always contact poison control first.
