A nurse is caring for a 3-year-old client who has persistent otitis media. To help identify contributing factors, the nurse should ask the parents which of the following questions?

"Has your daughter had a lot of earwax in her ears over the last month?"

"Does your daughter get water in her ears when you bathe her?"

"Has your daughter been drinking 6 glasses of water a day?"

"Does anyone smoke in the same house as your daughter?"
