Which term refers to agents that reduce or eliminate sensation. Types are regional, local and general?

• A. Regional anesthetic
• B. Anesthetics (Class)
• C. Local anesthetic
• D. General anesthetic

Answer: (B)

Anesthetics are substances that reduce or eliminate sensation. This term serves as the umbrella for all ways to block sensation, whether affecting a small area locally, a larger region, or the entire body. That’s why the best choice is the broad class name: anesthetics. Local anesthetics numb a small area by blocking nerve signals at the site of administration. Regional anesthesia blocks sensation in a larger region by inhibiting nerve transmission in a broader area. General anesthetics render the patient unconscious and insensate throughout the body. Since the question asks for the term that covers all these forms, the anesthetics class is the correct one; the other options describe specific forms rather than the overarching category.
