A patient complains that his hearing aid is not working. What actions should a nurse implement to assess the device? (Select all that apply.)

a) "Tonometry will allow inspection of the optic disc for signs of degeneration." Tonometry measures intraocular pressure (IOP) but does not provide direct information about the optic disc.
b) "This test will diagnose the type of your glaucoma."Tonometry measures IOP, but additional tests, such as visual field testing and optic disc examination, are needed to diagnose the type of glaucoma.
c) "Tonometry is performed to evaluate peripheral vision."Tonometry measures intraocular pressure, not peripheral vision. Visual field testing is used to assess peripheral vision.
d) "This test will measure the intraocular pressure of the eye." Tonometry is used to measure intraocular pressure, which is a key factor in diagnosing and managing glaucoma.

a) Coughing without letting food escape through the tracheostomy: After supraglottic laryngectomy, the patient may have difficulty swallowing and may require specific techniques to prevent aspiration.
b) Taking care of the tracheostomy, because the patient will always have to have one: While a tracheostomy may be necessary initially, not all patients will need it permanently.
c) Teaching the patient to swallow without aspiration: The loss of the normal anatomy for swallowing after supraglottic laryngectomy puts the patient at risk for aspiration. Rehabilitation and learning proper swallowing techniques are major postoperative concerns.
d) Teaching the patient to use an assistive device to speak: This is also an important consideration, but the primary issue postoperatively is managing swallowing to avoid aspiration.
