Final answer:
For a patient with otitis media, an antibiotic such as Cefixime (Suprax) would be the priority treatment to address the underlying bacterial infection.
Step-by-step explanation:
The priority treatment for a patient diagnosed with otitis media and presenting with a low-grade fever would be an antibiotic, as otitis media is typically a bacterial infection of the middle ear. Considering the available options in the question, the most appropriate medication would be Cefixime (Suprax), which is a cephalosporin antibiotic and can be effective against the pathogens commonly causing otitis media. Although pain relief is also important, addressing the underlying infection is the primary concern, and antibiotic therapy takes precedence.
