Treatment for someone sprayed with pepper spray or Mace might include:
A. 50 cc of thiomene.
B. 12.5 grams in 50ml of sodium thiosulfate.
C. plenty of fluids, such as Gatorade or Pedialyte.
D. removing the victim to fresh air.
I am guessing it would be D. But not too sure about that.
Why are you guessing? Your text materials should have the answer.
