Study notes for First Aid — part of the WAEC SSCE Health Science syllabus. 3 learning objectives with explanations and exam tips.
First aid is the immediate help given to a sick or injured person before a doctor arrives. Think of it as the quick action you take when someone gets hurt at home, school, or on the street.
The main aim of first aid is to save lives and prevent the situation from getting worse. When your classmate faints during assembly, giving first aid means keeping them safe and comfortable until the school clinic staff arrive. Another important aim is reducing pain and promoting quick recovery.
The key principles guiding first aid are simple: preserve life, prevent complications, and promote healing. You must stay calm, assess the situation carefully, and never move an injured person unnecessarily unless they're in immediate danger. Always get professional medical help as quickly as possible.
Remember, first aid is temporary emergency care, not permanent treatment. Your job is to stabilize the person and buy time until proper medical professionals take over.
A first aid kit is a collection of basic medical supplies you keep ready to treat minor injuries and emergencies before professional help arrives. Think of it as your immediate health response toolkit. Every home, school, and workplace should have one easily accessible. Your kit should contain items like sterile gauze, adhesive plasters, antiseptic solutions, pain relievers, antihistamines, and a thermometer. In Nigeria, many families keep their kits in a clearly marked box or cupboard in the kitchen or sitting room for quick access during accidents. A good first aid kit helps you handle cuts, burns, headaches, and allergic reactions at home, reducing panic and preventing infections. Regular checks ensure supplies aren't expired or damaged, keeping your kit always ready for use.
First aid means the immediate help you give someone before a doctor arrives. For cuts and wounds, clean with clean water and apply pressure with cloth to stop bleeding. If bleeding won't stop after ten minutes, get medical help quickly. For fractures and dislocations, don't move the injured part—immobilize it with a sling or bandage to prevent more damage. Burns from fire need cold water treatment for at least ten minutes, but never use ice directly on skin. Think of a Lagos trader who spilled hot soup on her arm—cold water helped reduce the burn damage before she reached the hospital. For poisoning, identify what was swallowed and call poison control or a hospital immediately. Shock happens when the body loses blood or fluids, so lay the person flat with legs raised. Never give food or water to an unconscious person. Asphyxia from choking requires you to clear the airway quickly using back blows or abdominal thrusts.
