What instruction should the nurse include in the discharge plan after a tympanostomy tube insertion?

Instructing the patient to use ear plugs during bathing is vital after a tympanostomy tube insertion. This guideline helps to prevent water from entering the ear canal, which can lead to infections or complications since the tympanostomy tube creates a direct passage from the external ear to the middle ear. Keeping water out of the ear is essential during healing and provides a protective measure for the newly placed tube, ensuring it functions effectively in equalizing pressure and draining fluid.

The other options present potential risks or do not align with best practices for post-surgery care after tympanostomy tube insertion. For instance, forcing the nose can increase pressure in the middle ear and disrupt the function of the tube. Continuous antibiotic administration is not generally required unless there is an active infection, and drainage should be monitored as it may still be normal in the post-operative period rather than disregarded.
