Correct Answer: A

Rationale: Acetaminophen (paracetamol) is primarily used for reducing fever and relieving mild to moderate pain. In this case, the key clue is the reduction of the patient's temperature to a normal level (37°
C) after administration. This indicates that the medication was given to manage a febrile condition. The mechanism of action involves inhibition of prostaglandin synthesis in the central nervous system, which reduces the set point of the hypothalamic thermoregulatory center. Although Acetaminophen can also relieve pain, the outcome recorded—a normalized temperature—directly points to its antipyretic effect, confirming that it was administered to treat fever rather than pain, nausea, or hypertension.
