A nurse is reinforcing teaching with a client who is postoperative following a tympanoplasty. Which of the following information should the nurse include?

The client scenario requires identifying post-surgical management for a middle ear reconstruction. To select the safest option, principles of pressure management, tissue healing, infection control, and fluid dynamics within the tympanic cavity must be applied to prevent graft displacement. Choice A rationale . Sneezing with a closed mouth redirects pressure through the eustachian tube into the middle ear. This sudden increase in intratympanic pressure can dislodge the newly placed tympanic membrane graft, causing surgical failure and recurrent perforation. Choice B rationale . Sucking through a straw creates negative pressure within the oral cavity and nasopharynx. This negative pressure is transmitted to the eustachian tube and middle ear, which can disrupt the delicate graft placement and hinder optimal healing. Choice C rationale . Strenuous exercise increases intracranial and intravascular pressure, which elevates middle ear pressure and risk of bleeding. Strenuous activities must be avoided for at least three to four weeks postoperatively to ensure stable graft integration. Choice D rationale . Shampooing hair within the first week poses a high risk of water entering the external auditory canal. Water introduction introduces pathogens into the surgical site, increasing the risk of otitis media and graft contamination.
