Which term refers to substances that counteract specific poisons?

• A. Chelating agents
• B. Activated charcoal
• C. Urine alkalinization
• D. Antidotes

Answer: (D)

Antidotes are substances that counteract the effects of a specific poison by neutralizing the toxin, blocking its action, or reversing the damage it causes. They are chosen to match the toxin involved, making them a direct countermeasure to poisoning. Other treatments like activated charcoal reduce absorption, urine alkalinization helps eliminate some toxins, and chelating agents bind certain metals, but the term that best fits the description of counteracting a poison with a targeted remedy is antidotes.
