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

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

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

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

Tilting the head back can cause blood to go down the throat. Instead, the person should lean forward and pinch their nostrils.

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

Swelling, deformity, severe pain, and inability to move the injured area are signs of a fracture.

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

Check if the person is responsive. If they are unresponsive, call 911 and begin CPR if needed.

Even if a head injury seems minor, delayed symptoms such as confusion, dizziness, or vomiting can indicate a serious problem.

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

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

Never remove an embedded object from a wound. It may be stopping severe bleeding. Apply pressure around the object and seek emergency care.

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

Animal bites should be cleaned with soap and water, and medical help should be sought to assess infection risk.

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

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

Pinching the nostrils and leaning forward helps stop bleeding while preventing blood from flowing into the throat.

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

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.

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

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

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

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

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

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).

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

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

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

Cold water is effective, but ice-cold water or direct ice application can cause further damage to the tissue.

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

If an allergic reaction affects breathing, administer an EpiPen if available and call 911 immediately.

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

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

Installing carbon monoxide detectors in homes and ensuring proper ventilation helps prevent CO poisoning.

A second-degree burn should be cooled with running water, covered with a clean bandage, and left undisturbed to heal.

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

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

Keeping the head and neck still is crucial to prevent further spinal damage.

Cleaning the wound with water and covering it with a sterile dressing prevents infection and promotes healing.

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

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

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

Clean the wound with soap and water and seek medical attention, as human bites can introduce harmful bacteria.

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

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

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

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

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