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).

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Inhaling toxic fumes can cause serious respiratory issues, and the first step is to move the victim to fresh air.

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

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

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

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

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

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

CPR is only performed if a person is unresponsive AND not breathing. If they are breathing, monitor them until help arrives.

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