A child with persistent otitis media with effusion is to undergo insertion of pressure- equalizing tubes via a myringotomy. The child is to be discharged later that day. After teaching the parents about caring for their child after discharge, which statement indicates that the teaching was successful?

A. "The tubes will stay in place for about a month and then fall out on their own.": Pressure-equalizing tubes typically remain in place for 6–12 months, not just a month, and fall out spontaneously. B. "His chances for ear infections now have dramatically decreased.": While tubes reduce the risk of middle ear effusion and some infections, they do not eliminate the possibility of future ear infections entirely. C. "He should wear earplugs when swimming in a pool or a lake.": Using earplugs during swimming helps prevent water from entering the middle ear through the tubes, which can reduce the risk of otitis media or ear infections after surgery. D. "We should keep the ears protected with cotton balls for the first 24 hours.": Routine cotton ball protection is not necessary unless directed by the provider; normal bathing and short exposure to water are generally permitted after surgery.
