A nurse is teaching a client about diagnostic vision tests. The nurse should include that which of the following tests is performed to diagnose macular degeneration?

Amsler grid.

Snellen chart.

Intraocular pressure.

Refraction test.

Answer and Explanation

The Correct Answer is A

Choice A reason: This is the correct answer because the Amsler grid test is performed to diagnose macular degeneration. The Amsler grid is a pattern of straight lines with a dot in the center. The client is asked to look at the dot and report any distortions or missing areas in the grid. This can indicate damage to the macula, which is the central part of the retina that provides sharp vision.

Choice B reason: This is incorrect because the Snellen chart test is not performed to diagnose macular degeneration. The Snellen chart is a chart of letters of different sizes that are read from a distance. The client is asked to read the smallest line they can see clearly. This can indicate visual acuity or sharpness of vision, but not macular degeneration.

Choice C reason: This is incorrect because the intraocular pressure test is not performed to diagnose macular degeneration. The intraocular pressure test measures the pressure inside the eye using a device called a tonometer. The client may feel a puff of air or a gentle touch on their eye. This can indicate glaucoma, which is a condition where increased pressure damages the optic nerve, but not macular degeneration.

Choice D reason: This is incorrect because the refraction test is not performed to diagnose macular degeneration. The refraction test measures how well the eye bends light rays using a device called a phoropter. The client looks through different lenses and reports which ones make their vision clearer. This can indicate refractive errors such as nearsightedness, farsightedness, or astigmatism, but not macular degeneration.

Correct Answer is C

Explanation

Choice A Reason: Inserting a nasal swab to observe the fluid is contraindicated, as it can introduce infection or increase intracranial pressure. The fluid can be tested for glucose or halo sign to confirm cerebrospinal fluid (CSF) leakage.

Choice B Reason: Suctioning the nose gently with a bulb syringe is also contraindicated, as it can create negative pressure and increase CSF leakage or cause meningitis.

Choice C Reason: This is the correct answer because allowing the drainage to drip onto a sterile gauze pad can prevent contamination and facilitate observation of the amount and characteristics of the fluid.

Choice D Reason: Inserting sterile packing into the nares is not recommended, as it can obstruct the drainage and increase intracranial pressure or infection risk.

A. "I will wear earphones during this test." B. "Small electrodes are placed on my scalp." C. "A small probe is placed inside my ear." D. "A tuning fork is placed on my head."

Correct Answer is D

Explanation

Choice A Reason: This is incorrect because earphones are not used in the Rinne test. The Rinne test compares air conduction and bone conduction of sound using a tuning fork.

Choice B Reason: This is incorrect because electrodes are not used in the Rinne test. Electrodes are used in electroencephalography (EEG), which measures brain activity.

Choice C Reason: This is incorrect because a probe is not used in the Rinne test. A probe is used in tympanometry, which measures the pressure and mobility of the eardrum.

Choice D Reason: This is correct because a tuning fork is used in the Rinne test. The tuning fork is placed on the mastoid process behind the ear and then moved near the ear canal to compare the sound perception.
