A nurse is teaching the parents of an infant who has been diagnosed with otitis media (OM) about ways to prevent future OM infections. Which of the following statements by the parents indicates further teaching is needed?

A. "We will avoid exposing our baby to secondhand smoke and sick individuals.": Avoiding smoke and sick contacts reduces the risk of upper respiratory infections, which are a major contributing factor to otitis media. This reflects correct understanding of preventive measures. B. "Our child can continue to receive breastfeeding.": Breastfeeding provides immunologic protection through antibodies that help reduce the incidence of otitis media, making this a correct preventive strategy. C. "We do not need to finish the prescribed antibiotic once the baby seems better to avoid unnecessary medication.": Not completing the full course of antibiotics can lead to incomplete eradication of bacteria, recurrent infections, and antibiotic resistance. This statement indicates a misunderstanding that requires further teaching. D. "We will always feed our baby in an upright position to help prevent ear infections.": Upright feeding reduces fluid accumulation in the middle ear, which helps prevent OM, reflecting proper parental understanding of preventive practices.
