Which of the following medications is an example of an NSAID?

The selection of Advil as an example of a nonsteroidal anti-inflammatory drug (NSAID) is accurate because Advil is a brand name for ibuprofen, which is classified as an NSAID. NSAIDs are commonly used to reduce inflammation, relieve pain, and lower fever. They work by inhibiting enzymes involved in the production of prostaglandins, which are compounds that mediate inflammation and pain sensation in the body.

The other medications listed serve different purposes: Tylenol (acetaminophen) is primarily an analgesic and antipyretic but does not have the anti-inflammatory properties typical of NSAIDs. Oxycodone is an opioid analgesic, used for managing moderate to severe pain but does not classify as an NSAID. Aspirin can also be categorized as an NSAID, but it's important to note that it was not chosen as the answer in this case. Since Advil (ibuprofen) is commonly recognized and frequently used as an example of an NSAID in educational settings, it stands out clearly in this context.
