A 4-year-old child diagnosed with otitis media continues to experience persistent ear pain after being treated with an antibiotic for 24 hours. The nurse practitioner should:

change the antibiotic.

increase the dose and frequency of acetaminophen (Tylenol) administration.

alternate ibuprofen (Advil) with acetaminophen (Tylenol) for pain.

re-evaluate the child after completing 48-72 hours of antibiotic therapy.
