Which of the following is listed as a general symptom under medical considerations for OC exposure?

• A. Nausea or vomiting
• B. Enlarged muscles
• C. Hyperactivity
• D. Drowsiness

Answer: (A)

OC exposure irritates mucous membranes and airways and can provoke a systemic response such as nausea. Nausea or vomiting is listed as a general symptom because irritation from the spray, whether inhaled or contacting the throat and mouth, can trigger nausea or a gag reflex. The other options don’t fit the typical pattern of OC’s general symptoms—enlarged muscles, hyperactivity, and drowsiness aren’t commonly associated with OC exposure. So nausea or vomiting is the best answer.
