Final answer:
Surgical treatment for Ménière's disease is meant to decrease fluid volume in the inner ear to alleviate symptoms such as vertigo, tinnitus, and hearing loss.
Step-by-step explanation:
The nurse understands that surgical treatment for Ménière's disease is performed to decrease fluid volume in the inner ear. Ménière's disease is characterized by an accumulation or over-production of fluid within the inner ear structures, which affects both equilibrium and hearing. The excessive fluid can lead to symptoms such as vertigo, tinnitus, and hearing loss. Removing impacted earwax or increasing fluid intake would not address the underlying problems caused by this disease, and while surgery may have a secondary effect on hearing loss, it is not the primary goal of the procedure.
