Final answer:
The nurse should question the prescription of amoxicillin for the 3-year-old with otitis media due to the client's allergy to amoxicillin causing wheezing.
Step-by-step explanation:
The nurse should question the prescription of amoxicillin for the 3-year-old with otitis media because the client has an allergy to amoxicillin that causes wheezing. It is important to avoid prescribing a medication that could potentially cause an allergic reaction, especially one that affects the client's breathing. The nurse should inform the healthcare provider about the client's allergy and suggest an alternative antibiotic that is safe for the client to take.
