A client newly diagnosed with glaucoma has a history of asthma. Which of the following medications newly prescribed by the eye doctor will the nurse question?

Choice A Reason: This choice is incorrect. Instilling eye drops in both eyes every hour around the clock is not an information that the nurse will provide, as it is not a recommended treatment for chronic bilateral inflammation of the eyelid margins. This condition is also known as blepharitis, which is a common and chronic disorder that causes redness, itching, burning, and crusting of the eyelids. Eye drops may be used to relieve symptoms, but not every hour or without a prescription.

Choice B Reason: This choice is incorrect. Using sterile gloves when assisting with activities of daily living is not an information that the nurse will provide, as it is not a necessary precaution for chronic bilateral inflammation of the eyelid margins. Blepharitis is not contagious or infectious, but rather caused by an overgrowth of bacteria or mites on the eyelids, or by an underlying skin condition such as seborrheic dermatitis or rosacea.

Choice C Reason: This is the correct choice. Using baby shampoo on the eyelid margins is an information that the nurse will provide, as it is a simple and effective way to clean and soothe the eyelids. Baby shampoo is gentle and non-irritating, and can help remove excess oil, debris, and scales from the eyelids. The nurse will instruct the caregiver to dilute a few drops of baby shampoo with warm water, apply it to a cotton ball or washcloth, and gently rub it along the eyelid margins. The nurse will also advise to rinse well with water and pat dry with a clean towel.

Choice D Reason: This choice is incorrect. Using a salt scrub inside the eyelid is not an information that the nurse will provide, as it is a harmful and painful method that can damage and irritate the eye. Salt scrub is abrasive and drying, and can cause corneal abrasion, infection, or inflammation. The nurse will warn the caregiver to avoid using any harsh or unapproved products on or near the eye.

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.
