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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

Never hold down a person having a seizure. Instead, clear the area and protect their head while allowing the seizure to pass.

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

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

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

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

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

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

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

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

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