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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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).

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

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

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

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

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

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

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

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

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

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

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

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

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

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