a. a girl has a burn on her arm.
I'll use cold water to ease the pain and then take her to the nearest clinic/ hospital if necessary.
b. a girl has a nose bleed
I’ll leave her lying flat and stuff her nose with cotton-wool to stop the bleeding.
c. a boy has a bad cut on his leg
I’ll wash the cut with bactericide. Then I'll bandage the cut to stanch it.
d. a boy has a bee sting
I’ll apply lime to the area around the sting to stop the stins from being swollen.
