What term means to directly apply a controlled substance by injection, inhalation, ingestion, or other means to the body of a patient or research subject?

• A. Administer
• B. Dispense
• C. Possess
• D. Manufacture

Answer: (A)

Administer is the term that describes directly giving a controlled substance to a patient or research subject, whether by injection, inhalation, ingestion, or another route. This word is used for the actual act of delivering the drug to the person, typically by a healthcare professional in a clinical or research setting. It differentiates from dispense, which is providing a medication to be used by the patient (often by a pharmacist) rather than giving it directly at the point of care. Possess means to have the substance in one's control, and manufacture means to produce or create the substance. So the act of directly giving the drug to the body fits the definition of administer.
