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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

CPR is only performed if a person is unresponsive AND not breathing. If they are breathing, monitor them until help arrives.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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