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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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