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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

A person with low blood sugar should be given a fast-acting sugar source like fruit juice or glucose tablets to restore normal levels.

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.

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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