A nurse is caring for an older adult client in the outpatient clinic.

A nurse is reviewing a client's medical record. Select the 3 findings that place the client at risk for hearing impairment.

Choice A rationale

Canned split pea soup is extremely high in sodium, which must be restricted in patients with Meniere disease. Excess sodium intake leads to fluid retention throughout the body, including the endolymphatic sac in the inner ear. This increases endolymphatic pressure, potentially triggering an exacerbation of vertigo, tinnitus, and hearing loss. Maintaining a low sodium diet, typically less than 2,000 mg per day, is a cornerstone of managing the fluid balance issues associated with this condition.

Choice B rationale

A baked potato with cheese and bacon contains significant amounts of hidden and added sodium. Bacon is a processed meat cured with salt, and cheese is naturally high in sodium content. For a client with Meniere disease, consuming such a high salt meal can cause a spike in the pressure of the inner ear fluids. These dietary choices are contraindicated because they directly contribute to the endolymphatic hydrops that characterizes the pathophysiology of the frequent dizzy spells.

Choice C rationale

Wine and other alcoholic beverages should be restricted because alcohol can change the fluid transport and concentration in the inner ear. Alcohol consumption can alter the volume and composition of the endolymph, which may aggravate the symptoms of Meniere disease. Additionally, alcohol affects the central nervous system and can worsen the sense of imbalance or dizziness already experienced by these clients. Restricting alcohol helps maintain a stable internal environment within the delicate structures of the vestibular system.

Choice D rationale

Iced coffee contains caffeine, which is a stimulant that can exacerbate the symptoms of Meniere disease. Caffeine has vasoconstrictive properties that can reduce blood flow to the inner ear and may also increase the perceived intensity of tinnitus. By stimulating the nervous system, caffeine can make the symptoms of vertigo more distressing for the patient. Clients are generally advised to eliminate or significantly limit caffeine to help stabilize the fluid dynamics and nerve sensitivity in the ear.

Choice E rationale

Milk is generally permitted in a diet for Meniere disease unless the patient has a specific allergy or intolerance. It provides essential nutrients like calcium and vitamin D without the high sodium levels found in processed foods or the stimulants found in caffeinated beverages. While overall fluid intake should be distributed evenly throughout the day to avoid sudden fluctuations, milk itself is not a primary trigger for endolymphatic hydrops. It is a safer choice compared to caffeinated or high sodium options.

Choice A rationale

A refraction test is used to determine a client optical prescription for eyeglasses or contact lenses. It involves the use of a phoropter to measure how light waves are bent as they pass through the cornea and lens. This test identifies refractive errors like myopia, hyperopia, and astigmatism. It does not provide information about the health of the retina or the presence of maculopathy, which is the primary concern in cases of suspected macular degeneration.

Choice B rationale

The Snellen chart is the standard tool for measuring distance visual acuity. It requires a client to read letters of decreasing size from a distance of 20 feet. While it can detect a general decline in vision, it is not specific to macular degeneration. A client with maculopathy might still have relatively good peripheral vision but struggle with central tasks. The Snellen chart evaluates overall clarity but lacks the precision needed to identify central scotomas.

Choice C rationale

The Amsler grid is a diagnostic tool consisting of a grid of horizontal and vertical lines used specifically to monitor the central visual field. Clients with macular degeneration will report that the lines appear wavy, distorted, or missing, a phenomenon known as metamorphopsia. Because the macula is responsible for sharp, central vision, this test is the most sensitive and appropriate bedside or clinic tool for detecting early changes and progression of this specific retinal condition.

Choice D rationale

Intraocular pressure measurement, typically performed via tonometry, is the gold standard for screening and monitoring glaucoma. Normal intraocular pressure ranges from 10 to 21 mmHg. Elevated pressure can lead to optic nerve damage, but it is not a diagnostic marker for macular degeneration. Macular degeneration is a disease of the retinal tissue itself, often related to aging and oxidative stress, rather than the fluid pressure dynamics inside the anterior chamber.
