What term describes a chemical substance used in the diagnosis, treatment, cure or prevention of disease?

• A. Drug
• B. Vaccine
• C. Nutrient
• D. Toxin

Answer: (A)

A drug is the term that fits this description. A drug is a chemical substance used in diagnosing, treating, curing, or preventing disease. It covers the medicines and other therapeutic agents doctors use to manage health conditions and keep people from getting sick. Nutrients are substances needed for nutrition and energy, not primarily for diagnosing or treating disease. Toxins are harmful substances that cause disease or harm. Vaccines are focused on preventing disease by building immunity, and while they are used to protect health, they are not the broad category used for all diagnostic and therapeutic purposes in the same way that drugs are. So, drug is the best fit.
