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

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

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

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

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

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

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

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

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).

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

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

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

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

Signs of heat stroke include confusion, hot/dry skin, and rapid pulse. Unlike heat exhaustion, the victim does NOT sweat.

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

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

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

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

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

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

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

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

You should call Poison Control immediately for instructions instead of trying to induce vomiting, which can make the situation worse.

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

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

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

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

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

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

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

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

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

If an inhaler is not available and the attack worsens, call 911 immediately as it may become life-threatening.

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

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

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

The first priority in treating a deep open wound is to apply direct pressure to control bleeding before cleaning and dressing the wound.

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

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

Symptoms of shock include pale skin, weak rapid pulse, nausea, and excessive thirst. A slow, strong pulse is NOT typically associated with shock.

Cold therapy (ice) is recommended for the first 24-48 hours to reduce swelling and pain. Heat can worsen swelling early on.

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

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

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

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

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

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

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

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

Wild animal bites carry a high risk of rabies or infection and should always be examined by a medical professional.
