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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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).

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

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

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

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

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

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

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

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

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

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