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.

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

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

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

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

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

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

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

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

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

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).

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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