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

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

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

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

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

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).

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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.

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

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

Frostbite should be treated by gradually warming the affected area using warm water (not hot) and seeking medical help.

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

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.

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