Which term means 'producing a strong effect'?

• A. Ongoing
• B. Potential
• C. Potent
• D. Pathogenic

Answer: (C)

Potent describes something that produces a strong effect, often with a small amount. In medical or pharmacology contexts, potency reflects how strong an effect a drug has per dose—the higher the potency, the smaller the dose needed for the effect. For example, a potent analgesic can relieve pain quickly at low doses. The other terms don’t convey strength in that way: ongoing means continuing over time; potential means possible or capable but not the actual strength; pathogenic means disease-causing.
