Which statement best describes OC spray's effect on the eyes?

• A. It primarily affects the digestive system
• B. It causes tearing, coughing, burning
• C. It has no effect on the respiratory tract
• D. It only affects the skin

Answer: (B)

OC spray irritates the eyes and mucous membranes. The capsaicinoids in it stimulate pain receptors in the conjunctiva, provoking reflex tearing and a burning sensation. The irritation can extend to the nose and throat, often causing coughing and a sense of choking, which together create the common eye response of tearing, burning, and coughing. This description best captures how OC spray acts on the eyes. It isn’t limited to the skin or digestive system; it also affects the respiratory tract, which is why coughing is typical, and it does not have no effect there.
