What is the definition of an anesthetic drug? Adrug the decreases the pain felt by a patient A drug that is used in surgeries to ensure the patient does not become infected A drug that blocks the reception of pain Adrug that alters the brain to induce a coma-like state

An anesthetic drug is a medication used to relieve pain or to induce a coma-like state during surgeries. The primary purpose of an anesthetic drug is to block the reception of pain, making the patient feel no pain during medical procedures. Option A is partially correct but does not fully capture the primary function of an anesthetic drug. Option B is incorrect because anesthetic drugs are not specifically used to prevent infections. Option D is also incorrect because, while some anesthetic drugs can induce a coma-like state, it is not their primary function. Therefore, the most accurate definition of an anesthetic drug is given in Option C.
