Why does administering antipyretics, such as acetaminophen, to a patient with a fever reduce body temperature rather than just suppressing shivering?

A)They inhibit skeletal muscle ATP production
B)They decrease brown fat metabolism directly
C)They block peripheral vasoconstriction signals
D)They reset hypothalamic temperature set-point

💡 Explanation

Antipyretics like acetaminophen reduce fever because they inhibit prostaglandin synthesis in the hypothalamus, thereby resetting the body's temperature set-point to a lower level, therefore reducing the perceived need for heat generation. This mechanism corrects the root cause of the fever, rather than simply suppressing shivering.
