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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Installing carbon monoxide detectors in homes and ensuring proper ventilation helps prevent CO poisoning.

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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.

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

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

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

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

Installing carbon monoxide detectors and ensuring proper ventilation can prevent dangerous CO buildup.

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

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

Frostbitten areas should be warmed slowly using warm water (not hot) 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.

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