While the nurse is completing the assessment of the child with Reye's syndrome, the parent states that multiple OTC medications were given before hospitalization to treat the child's influenza symptoms. Which medication stated by the parent is most important for the nurse to report to the HCP?

A: Acetaminophen (Tylenol) is an aspirin-free analgesic and antipyretic. B: Although the etiology of Reye's syndrome is unknown, the condition typically occurs after a viral illness, such as influenza, and is associated with aspirin (acetylsalicylic acid) use during the illness. Bismuth subsalicylate (Pepto-Bismol) contains aspirin. C: Pseudoephedrine (Sudafed) is an allergy and/or cold remedy used for nasal drying and decongestion. This does not contain aspirin. D: Diphenhydramine (Benadryl) is an antihistamine. This does not contain aspirin.
