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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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