Answer:
(a) Heavy bleeding: make the person lie down, raise the injured part, and press a clean cloth or sterile pad firmly on the wound. Keep the pressure, tie a bandage over the pad and take the person to a doctor quickly.
(b) Minor burn: hold the burnt part under cool running water for 10–20 minutes. Remove rings or tight things before swelling starts. Cover it loosely with a clean cloth; do not burst blisters or apply oil, butter or toothpaste.
(c) Fracture of the arm: do not move or try to straighten the bone. Support the arm on a splint (a stick, cardboard or folded newspaper) with padding, tie it gently, put it in a sling made of a triangular bandage and take the person to a hospital.
